12 PROCEEDINGS OF THE 



thorax, apex more or less truncate, slightly pointed ; sheaths of 

 saw hairy, exserted ; blotch very large. Feet whitish testaceous ; 

 base of coxae black ; aj)ex of coxae, trochanters, and basal half of 

 femora more or less obscured with black or fuscous ; apex of tarsi 

 fuscous. Wings smoky, apex hyaline ; nervures deep black, 

 stigma large; 1st marginal cellule triangular, smaller than the 2d; 

 marginal nervure received a little past the middle of 2d sub- 

 marginal cellule; 1st sub-marginal cellule nearly double the 

 length of 2d, and near its apex there is a conspicuous round black 

 horny point; 2d sub-marginal cellule not much longer than broad, 

 anded where the recurrent nervure is received. 



The male is similar as regards coloration ; the antennae are a 

 good deal thicker, slightly compressed; the 3d joint scarcely 

 longer than the 4th (in the female it is perceptibly longer), and 

 the femora have usually more black on them. 



Length If lines. 



Pumilio can only be confounded with hetidae, and from that 

 species it can easily be known by its shorter antennae, perfectly 

 smooth head, the position of the marginal nervure, and the smoky 

 wings with hyaline apex. From the descriptions of Hartig and 

 Thomson it seems to vary considerably in the coloration of the 

 body. The former author describes it as having the mouth, 

 antennae, abdomen, and feet dark brown, with the knees, tibiae, 

 and tarsi pale brownish-yellow; while Thomson states that the 

 antennae are fuscous beneath, and the palpi, knees, tibiae, and tarsi 

 whitish-testaceous. A British specimen in my collection has a 

 dark brown splash across the mesonotum. 



Common, and generally distributed. 



The larva is sordid white ; the head pale brown, darker at the 

 sides; mouth dark brown; eyespots black. The thoracic feet are 

 banded with brown, the abdominal are marked posteriorly Avith a 

 semi-circular black mark, and the anal pair are surrounded with 

 black. On the back the 2d segment is black or brownish-black, 

 and sometimes on the 3d and 4th there is a narrow band ; beneath 

 the 2d segment is dark brown ; there is an irregular band on the 

 3d and 4th, and on the 5th and Gth a round dot, but these are 

 frequently absent. When full-fed the markings are cast off. 

 Length from 9 to 10 lines. 



They mine the leaves of lluhus frucUcosus and IL idaeus, and 

 to the raspberry they often do so much damage that, according
