During the grasshopper egg surveys conducted in Saskatchewan by the Dominion Entomological Laboratory at Saskatoon since 1932, bee fly larvae were commonly found destroying grasshopper egg pods. In the early years of these annual surveys little was known regarding the species, life-history or economic importance of these larvae. This prompted a study of the bionomics of the species, subsequently determined as Systoechus vulgaris Loew, and a morphological study of its immature stages.

This publication describes the life history and morphology of the immatures of Spaethiella intricata associated with bromeliads. Immature stages were previously unknown for the species. Adults and larvae are bromeliad leaf scrapers. First and fifth instar larvae and pupa of S. intricata are described and illustrated with further discussion upon the epipharynx of some Cassidinae species belonging to few tribes. General observations of the known Hemisphaerotini immatures and adults are compared.

Major Project

In the realization that all exact field experimentation and census work with insects is dependent upon accurate recognition of the species involved, a study of the comparative external morphology of the larvae was planned, from the first. as an integral part of the major project on wireworms, which was incepted in 1922, at the Dominion Entomological Laboratory, Saskatoon, Saskatchewan. The soundness of this viewpoint has been amply demonstrated, in that the morphological work has repeatedly proved to be vital to the whole economic study of this pest, which is being increasingly recognized (King, 1928; Seamans, 1933) as one of the major problems of wheat-growing in western Canada.

One New Species

The taxonomy of the hylicine genus Hatigoria Distant is reviewed based on morphological study of the types and other specimens. The male external morphology and genitalia of two known species, H. praeiens Distant, 1908 and H. sauteri Jacobi, 1914, are described and photographed for the first time. A description and figures of the female ovipositor of H. praeiens Distant, 1908 are provided. One new species, H. longistylia n. sp., from Laos and China is reported with descriptions and figures. This also represents the first record of the genus Hatigoria from Laos. A key to adult males of all species is provided.

Harmful Insect

In the case of any harmful insect of economic importance, in order to war against it, or apply remedial measures at all intelligently, a knowledge of the life-history of the pest is necessary. This proposition will, I think, meet with such ready acceptance as to render proof unnecessary, but I might in illustration mention two cases which came under my own observation, where in the one case a knowledge of the round of life of the attacking insect saved a whole forest, and in the other proved of great importance.

Two New Species

In studies of army ants on Barro Colorado Island, Canal Zone, Panama, C. W. Rettenmeyer collected two new species of Euryomma in association with colonies of Eciton burchelli (Westw.). Adults of both species were collected flying above refuse heaps of the ants, a good series of one was reared, and all stages of the larvae of both were taken in berlese samples of the refuse deposits. Descriptions of all stages of both species, except for the egg and puparium of the rarer species, are presented here. No immature stages of Euryomma spp. have been known previously, nor are there any published data on the life-history and habits of any species of the genus.

A number of species of this genus of Encyrtid parasites are known to be, and others are suspected to be, secondary parasites ; but apparently the complete life-history has not been observed in any one case. As the genus has an almost world-wide distribution and is doubtless of considerable economic importance, the following observations made in Southern California in part of 1935 and 1936 are recorded.
