﻿March 1895.] DvAR. CLASSIFICATION OF LePIDOPTERA. 21 



are less numerous than in scarodactyhis, and are more confined to the dorsal area, 

 being also slightly more pointed and tubercular. The small, slender abdominal 

 feet have no crotchets. 



Platyptilus rhododactylus. 



Setae distinct, ratiier coarse, single, arising from somewhat enlarged conical 

 tubercles, supplemented by a number of short secondary hairs with enlarged tips; 

 i dorsad to ii, not appro.ximate: iv and v closely approximate, all normal. Feet 

 slender, the crotchets in a single row forming a semicircle on the inner side of the 

 planta. 



Oedematophorus lithodactylus. 



Tubercles converted into small warts, each bearing some ten to twelve setae; 

 1 and ii in line, closely appro.ximate but not consolidated; iii lateral, behind it a 

 little secondary wart with one small seta; iv+v also with a little secondaiy wart 

 with three setce behind; vi and vii each a distinct wart; viii represented by rather 

 numerous hairs on the base and inside of the leg. Legs slender, the crotchets in a 

 half circle on the inner side. 



Oxyptilus periscelidactylus. 



Tubercles converted into moderate sized warts with si.x to twelve long hairs; 

 body also rather sparsely covered with short secondary hairs with enlarged tips: i 

 and ii entirely consolidated into a single wart, a single long seta behind iv+v; viii 

 a single seta; other warts normal. 1-egs slender, the crotchets forming two-thirds 

 of a circle on inner side. 



Family DIOPTID.^. 

 Phryganidia californica. 



Mr. T. G. O. Mueller has kindly obtained the larvK of this 

 species for me in its home in California. The larvae are referable 

 to the Noctuina. 



Setce small and inconspicuous, but normal; a slight development of smaller 

 secondary setae consisting of one above and caudad to iii, another below and caudad 

 to iii close above the spiracle; iv and v remote, iv moderately well moved up; many 

 setae on the leg plate. Larva otherwise naked, noctuiform; joint 12 enlarged and 

 13 small; anal feet slender, divergent and rather weaker than the others. 



Family BREPHIDy^:. 



I have before me the larvae of three European species of 

 Brephos. The setse are greatly reduced, but the tubercles remain 

 rather distinct, in the normal arrangement of the Noctuina, with- 

 out secondary hairs. The interesting point is the structure of the 

 legs. All the abdominal ones are present, but the three anterior 

 pair are about half aborted. In the Geometridre, these legs are
