334 Mr. H. W. Bates's descriptions, ^c. 
insect agrees with Singilis in pal])i, tarsi, &e., but differs 
in the naiTOwer neck, more explanated margins of the 
thorax, and rather more convex elytra. Tlie tarsi are 
hairy above ; the fourth joint strongly bilobed ; the claws 
pectinated. The metathoracic epimera are extremely 
short and inconspicuous, as in Singilis, Endynomena, and 
allied genera; the labial palpi have the terminal joint very 
much thickened, but not securiform, and obtusely trvm- 
cated. The interstices of the elytra are impunctate, as in 
S. bicolor, but I do not perceive the two setiform punc- 
tures on the third.
