well developed than are the maxillae. It consists of a pair of whit- 
ish pilose fleshy convex lobes, each about twice as long as broad, 
with a pair of brown rudimentary palps, the former being fused 
with, and the latter closely apposed to, the surface of the highly 
polished, densely fringed but otherwise hairless hypopharynx, 
which fills up the space between the maxillae. The strongly chitin- 
ized ventral plate behind the mouth parts is much shorter than the 
clypeus ; it bears a pair of longitudinal grooves close to the middle- 
line, and its anterior margin is lightly concave as a whole. 
Both the dorsal and ventral plates of the prothorax are dull 
as a whole, owing to an even and almost microscopically fine 
granulation; but the median ventral groove with a strongly fan- 
shaped area in front of it, and the dorsal YW with a less expanded 
area in front of it, are polished. The rest of the body is dull 
except for the posterior end which is polished. 
This larva closely resembles larvae of the allied genus Dzcerca, 
as these are defined in Xambeu’s key to the genera of Buprestid 
larvae. 
TENEBRIONIDAE. 
A key to the genera of Tenebrionid larvae was published by 
Schigdte (Nat. Tidsskr., X1, 1877-1878, pp. 491-522). Thishas been 
republished by Kiesenwetter and Seidlitz, who also give a new 
key (Naturg. Ins. Deutschl., Coleoptera V [1], pp. 210-216). 
The following is a list of the references I have been able to 
find to descriptions of Tenebrionid larvae. Those not available in 
Calcutta are marked with an asterisk.
