﻿March 1895.] DvAR. CLASSIFICATION OF LePIDOPTERA. 19 



a small black area; vii without any black area, consisting of three setre above base 

 of foot; viii inside of base of foot next niidventral line. Abdominal feet slender, 

 well developed, the crotches in a single complete circle. 



Gelechia rhombella. 



A distinct corneous cervical shield. Set;\; distinct, but witliout corneous areas; 

 i dorsad to ii, remote; iv and v closely approximate, normal; feet moderate, the 

 crotchets in a ring. 



Endrosis lacteella. 



Cervical shield well cornilied, large; seta> long and line, the tubercles scarcely 

 perceptible; i dorsad to ii, iv and v closely approximate, all normal. Feet well 

 developed, the crotchets in a single circle. 



Plutella porrectella. 



Cervical shield reduced to a series of dots. Setrc fine, short, but black and 

 very distinct, arising from minute black tubercles; i dorsad to ii; iv and v in line, 

 rather remote, entirely unconsolidated; other setce normal; vii composed of three 

 closely approximated seta.\ Feet well developed, the crotchets in a circle but break- 

 ing down and incomplete on the outer side. 



Hyponomeuta cognatellus. 



Cervical shield distinct. Setae fine but long, from minute obscure tubercles' 

 ii slightly dorsad to i (compare PsychidDe), i being situated at the upper border of 

 a subdorsal black patch; iii lateral; iv and v remote, iv being moved up out of line 

 with V, almost on a level with lower border of spiracle; vi posteriorly subventral; 

 vii of three setae on base of leg, the upper one not closely approximated to the 

 other two; viii next midventral line. Abdominal feet rather short, the crotchets 

 three rows deep in a circle. 



Acrolepia assectella. 



Cervical shield sub-corneous. Setre short, from minute tubercles surrounded 

 by a diffuse sub-corneous area; i dorsad to ii, normal; iii close above the spiracle 

 and slightly anterior; iv and v remote, iv moved up a little out of line; vi pos- 

 teriorly subventral; vii of three setae closely approximated; viii normal. Feet 

 moderate, a single outer circle of crotchets and a second concentric inner row, 

 represented only on the inner side of the foot (i. e. broadly broken outwaidly). 



Laverna phragmitella. 



Cervical shield not distinguishable, the larval shape thicker than usual, slightly 

 flattened approaching the shape of the Anthrocerina. Setae fine, obscure, tubercles 

 absent; i slightly dorsad to ii; iii above spiiacle; iv and v greatly reduced, scarcely 

 to be made out under a half-inch objective, apparently in line and rather remote; 

 vi, vii and viii normal; feet well developed with a single circle of crotchets. 



Tinea pellionella. 



Cervical shield distinct. Setre short, very fine, obscure, tubercles absent; 

 dorsad to ii; iii lateral; iv and v not very closely approximate; iv dorsad to v, the
