Natural Groups

AbstractThe genus Ips is one of four closely related genera in the tribe Ipini, sub-tribe Ipina (De Geer 1775, Balachowsky 1949, Nunberg 1954, Hopping 1963). There are now 32 species of Ips recognized in North America, with a few more as yet undescribed. This paper defines the groups of closely related species with observations on the group relationships of species from other parts of the world. Work is in progress to define the North American species in each group.

General Appearance

The family of Nemistrinidæ comprises throughout the world one hundred and ten described species, six or seven of which are from Southern Europe and three from North America; the remainder nearly equally distributed in Asia, Africa, Australia and South America. In their habits, so far as known, the species approach the Bombylidæ most closely, as also do many in their general appearance. Structurally they are of interest to the Dipterologist, on account of their intricate and diverse neuration, which in some species is almost Neuropter-like in the reticulation.Doubtless the number of our species will be augmented by future discoveries, but yet we can never expect a very material increase.

Permian neogondolellids from south China: significance for evolution of the serrata and carinata groups in North America

Stage Boundaries

TheNeogondolella serrata(Clark and Ethington) group was originally reported as a North American provincial conodont lineage. More or less complete Permian sequences now recognized in China include species originally thought to be part of the North American provincial fauna as well as species reported previously from other parts of the world. Comparison of Chinese and North American species may be useful in correlation of series and stage boundaries between the two areas. The Chinese conodont succession demonstrates that most Permian neogondolellids were not provincial but attained worldwide distribution. Late Permian ancestors of Early TriassicNeogondolellaspecies were apparently widespread in the Tethyan Sea and the sudden appearance of TriassicNeogondolellaspecies in North America without Permian ancestors is only the consequence of the absence of the latest Permian marine rocks in North America.Of particular regional stratigraphic interest is the occurrence of the North American speciesN. wilcoxiClark and Behnken in the Chinese late Guadalupian-Dzhulfian. This occurrence supports a late Guadalupian (post-Lamar) age for the uppermost Gerster Formation in Utah.

AbstractIps calligraphus (Germar), I. ponderosae Swaine and I. interstitialis (Eichhoff) represent one variable species with the oldest name, Ips calligraphus (Germar) taking precedence. Ips calligraphus can always be recognized by the six spines on each side of the declivity. All other species in North America have less than six spines on each side.

A new species, Pholis clemensi, referred to the family Pholidae, is named and described from 12 specimens taken in southern British Columbia waters and the Strait of Juan de Fuca. Pholis clemensi is compared with other members of the genus, and a key is given to the North American species.

New distributional records, new larval host records, various collecting notes, and observations are reported for the North American species of the tribe Agallissini LeConte, 1873 (Coleoptera: Cerambycidae: Cerambycinae): Agallissus lepturoides (Duponchel & Chevrolat, 1841), Osmopleura chamaeropis (Horn, 1893), and Zagymnus clerinus (LeConte, 1873). The species are illustrated and distribution maps are provided.

The Byrrhidæ of this continent have received a comparatively small share of attention at the hands of systematists for many years, so that it is not at all surprising to find novelties among recently-collected material. Two new forms of the genus Pedilophorus have recently been detected among the accumulations in my cabinet, both of them from the west; no doubt still others remain to reward explorers of the mountain ranges and of the northern districts. The European fauna contains ten species, while but four were previously known from North America.

First Time

All macropterous species of Aptilotus Mik are keyed, with descriptions of two new macropterous North American species, Aptilotus pogophallus and A. nigriphallus. New distributional records are given for other North American species, and brachyptery is noted for the first time in A. luctuosus (Spuler). Four new macropterous species of Aptilotus (glabrifrons, spinistylus, rufiscapus, and binotatus are described from Nepal. The relationships between the North American and Nepalese species are discussed. Minocellina Papp is synonomized with Aptilotus, and the two species formerly in Minocellina, A. thaii (Papp) and A. besucheti (Papp), are thus given as new combinations. Limosina carbonicolor Richards, from Ethiopia, is redescribed and transferred to Aptilotus.

A New Species

Adults of Odontocepheus rumbleseatus n.sp. are described, the second Odontocepheus species known from North America. An unusual, deep posterior depression on the notogaster easily separates this species from all others in the genus Odontocepheus. Specimens were collected from hardwood leaf litter and rotten wood. The known distribution is Illinois and West Virginia south to northern Florida. Additional characters for separating the North American species O. oblongus (Banks) from O. elongatus (Michael) in Europe are presented, and the presence of O. elongatus in North America is documented.

There has been much confusion between the North American species of leafhoppers of the genus Streptanus Ribaut, partly because the species are so closely related and partly because the extent of the variation in markings and wing length was not fully appreciated. Four species have been found in North America, of which three hwe been recorded previously. The four are conspecific with species described from Europe, and the specific names that have been applied to North American species must be reduced to synonymy.
