THE CANADIAN ENTOMOLOGIST. It 



of doors. On July 6lh they could not be seen, but tlie leaves were 

 speckled with transparent sj^ots, on the under eide, showing black grains, 

 probably the dried sap, and upon holding the leaves against the light 

 the tiny larvae were revealed, either still on the surface or having just cut 

 their way between the two cuticles. 



Mature larva. — 8 mm. long, very slender, dull olive green or 

 brownish in colour, with cons])icuous darker tubercles each giving rise to 

 several long, rather bristly hairs. Head large, smooth, pale brown with 

 black trophi. Cervical collar semicircular, in colour and texture resem- 

 bling the head. Full cotTiplement of legs and pro-legs, the latter 

 unusually long. These larvifi are not confined to a single mine, but often 

 leave one to excavate another and are therefore often seen crawling on 

 the surface of the leaves. Pupa, slender, very pointed posteiiorly, pale 

 brown, inclosed in frail, open-meshed cocoon on under side of leaf or in 

 angles of leaf-stalks. Imago appears in from 8 to lo days in summer, 

 and there are at least two successive broods. 



This insect feeds by forming a puffy mine on Piinpinella (Zizzia) 

 integerritiui, in this locality a not very common Umbellifer. I first bred 

 it many years ago, and took it with me when visiting the family of Dr. 

 Fernald, and the latter traced it to the genus Chauliodus, Tr., but, as at 

 that time I did not know that it was new and had not its complete 

 life-history, did not attempt a description. Since then I have learned 

 from Lord Walsingham and Mr. Durrant that Chauliodus, Treit., is pre- 

 occupied by Epermenia, Hiib , and also that the species was probably 

 new to science. 



Eucatoptus striateiia, n. sp. 



A?iienfice long, dull ochreous, inclining to brown; basal joint compar- 

 atively large, especially in the S  Palpi with second and terminal joints 

 about equal in length, second joint densely but closely tufted, pale buff 

 or cinereous with indistinct leaden dots and shadings. Head and thorax 

 pale buff, faintly striped with leaden gray. Patagia of the paler colour. 

 Fore ivings light brown or brownish-ochreous, sparsely speckled with 

 black. A subcostal black, longitudinal line extends from base to apex, 

 curving upward slightly and intensifying at the latter ; beneath this, two 

 more or less definite blackish striations, the one on inner margin being 

 quite broad and diffused, while the discal streak is variable, not continuous, 

 often consisting of two or three dashes. Hind wijigs silken, ashy white, 

 shading to cinereous at tips. <5 with pencil of spreading hairs from base
