Posterior Position

Two phyletic lines are present in the Percidae: the Percinae, in which the anteriormost interhaemal bone is much larger than the posterior ones and the anal spines usually are well developed, and the Luciopercinae, in which the interhaemal bones are of uniform size and the anal spines are poorly developed. Parallel evolution has produced in each subfamily small, benthic, rheophilic forms with depressed or terete bodies and reduced or vestigial swimbladders. This differentiation is shown by dividing each subfamily into two tribes. Within the Percinae, the Etheostomatini (Percina, Ammocrypta, and Etheostoma) are interpreted as derivatives of the Percini (Perca, Gymnocephalus [=Acerina], and Percarina). The North American species Perca flavescens is distinguished from the Eurasian species P. fluviatilis and P. schrenki on the basis of the more posterior position of the predorsal bone. In the Luciopercinae, the Romanichthyini (Zingel [=Aspro] and Romanichthys) have evolved from the Luciopercini (Stizostedion [including Lucioperca]).

Generic Relationships

The systematic position of the genus Massalongia and the closely related genera Koerberia, Vestergrenopsis, and Placynthium in the family Peltigeraceae including lichens with hemiangiocarpic apothecia is discussed. The ontogeny of a hemiangiocarpic apothecium is described briefly. A key for the determination of the genera is provided.A general survey is given for the morphology and anatomy of the genus Massalongia. The two species, M. carnosa and M. microphylliza, are described in detail. The new combination M. microphylliza is made.

A New Species

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.

A new approach to the phylogeny of Euascomycetes with a cladistic outline of Arthoniales focussing on Roccellaceae

Bitunicate Ascus

A phylogenetic working hypothesis of euascomycete relationships is presented. Paraphysoidal ascolocular fungi are monophyletic and ascohymenial fungi are paraphyletic as paraphyses are considered plesiomorphic and paraphysoids apomorphic within euascomycete fungi. As a result it is not necessary to postulate parallel evolution of the bitunicate ascus, and furthermore presence of paraphyses in the prototunicate caliciaceous fungi is no longer in conflict with paraphyses in ascohymenial fungi. A cladistic outline of the order Arthoniales with special focus on the Roccellaceae including 20 taxa and 92 characters is presented. The type species of all genera considered are used as terminal taxa. It is suggested that the type species of Arthothelium should be excluded from the order Arthoniales. The Arthoniaceae are paraphyletic as Arthonia radiata and Arthothelium spectabile form a grade pair. The family Roccellaceae is monophyletic and corroborated in its traditional sense, but some rearrangements within the family are made. Opegrapha vulgata and Lecanactis abietina form a pair, but the family Opegraphaceae is paraphyletic if the pair Chiodecton sphaerale and Schismatomma pericleum are included. The originally described ascoma of the species Darbishirella gracillima, Ingaderia pulcherrima, and Reinkella fragillima are found to be lichenicolous fungi. The mycobiont ascomata of Darbishirella gracillima produce 3- not 2-septate spores. No ascomata of the mycobionts of the two latter species have as yet been found. Key words: Euascomycetes, Arthoniales, Roccellaceae, phylogeny, cladistics, lichenicolous.

The Family

The family Opomyzidae is composed of small (2.0 mm.-4.4 mm.), slender, usually brown or reddish flies; the wings have at least an apical spot and are usually more heavily marked. Several species of the genus Geomyza have the wings reduced and are nearly flightless. The few species whose larvae are known feed in grass stems. Some are of minor economic importance in Europe but none have been so reported in North America.

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.

The North American species of Trichoceridae belong to three genera, Diazosma Bergroth (subsinuata Alexander), Paracladura Brunetti (trichoptera Osten Sacken) and the dominant Trichocera Meigen, with numerous species, some of which are widely distributed throughout the Holarctic Region. The scope of the family, its phylogenetic relationships, and a key to the known genera, are all discussed in a recent paper by the writer. (The Trichoceridae of Australia; Proc. Linnean Soc. N. S. W., 51 : 299—304; 1926) and need not be considered further at this time.
