when found have probably been mistaken for larvae of Corv- 

 dalis. 



There are two lots, or 14 unnamed specimens, from the Hima- 

 laya region, in the Museum of Comparative Zoology, sent from 

 Kullu, by M. M. Carleton, a missionary, eome years ago, (One 

 lot dated 1872). These I consider are larvae of Neuromus, as 

 they dilxer materially from the Corydalis larvae so familiar to 

 us, and as adult specimens of Neuromus were sent by the same 

 collector from the same region, and Corydalis has never been 

 reported from that part of Asia. 



They are distinguished from Corydalis (1) by the black ring 

 about the spiracles; (2) by the antennae being only five jointed 

 as in Chauliodes larvae; (3) by the abdominal gill tufts being 

 more distinctly peduncled. 



They have eight pairs of abdominal spiracles, one well de- 

 veloped pair and one rudimentary pair on the thorax; seven 

 pairs of tracheal gill tufts. The body, above is very black with 

 the clavate projections. These are found distributed over the 

 more flexible parts of the body and filaments. Lateral filaments 

 eight pairs, with a row of tufted hairs on dorsal side of six 

 front pairs, more tufts on the others. The head and thorax are 

 dark without distinct markings. Prothorax longer than wide 

 and as wide as the head; eyes each with six ocelli; labial palpi 

 with three joints above the base. 



The larvae appear much like those of Chauliodes, but the pres- 

 ence of the tracheal gill tufts excludes them from that genus, 

 while the black ring and center of each spiracle, as well as the 

 five jointed antennae, separate them quickly from Corydalis. 



Eggs. The eggs of this genus have never yet been recognized, 

 but we would expect them to be most like those of Corydalis.
