The type of this genus is a little insect having somewhat the 
general appearance of a Cryptophagus, and which appears to me to 
come between Ammobius and Phaleria. I have not, however, ven- 
tured to examine the oral organs of my solitary specimen, for which 
I am indebted to Mr. Bakewell; but apparently they are not very 
different from those of Phaleria. 
Hyocis Bakewelli. 
H, fusco-ferruginea ; elytris fortiter striato-punctatis.

Dark ferruginous ; head and prothorax closely punctured, the punc- 
tures rather large and shallow, the raised intervals having a reticulate

its anterior angles rounded, its posterior acute; scutellum small, trian- 
gular; elytra scarcely broader than the prothorax, coarsely striate-

tures ; on the abdomen they are scattered and nearly obsolete, each with 
a small silvery hair; lees reddish testaceous. Length 12 line,
