when found have probably been mistaken for larvae of Cory- 
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, some years ago. (One 
lot dated 1872). These I consider are larvae of Neuromus, as 
they differ 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 ia. 
They are distinguished from Gonpdein (1) by the black ring 
about the spiracles; (2) by the antennae being only five jointed 
as in Chauliodes larvae; (8) 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.
