94 Mr. F. P. Pascoe on the Colydiide 
it Sosylus Squirei*, after the ardent collector who discovered it, and 
who, unfortunately for science, has since fallen a victim to yellow 
fever. All the species have the prothorax impressed with shallow 
oblong punctures, differing, however, in size ; and the elytra, which 
have four carinz on each, are deeply fluted posteriorly, less so at the 
base, the sculpture of the interstices varying. According to Mr. 
Bates’s notes they “ drill into the solid wood of Inga trees,’ and run 
“very nimbly over the trunks of dead trees.” The larvae are wood- 
eaters,

Hab. Figa? 
Dark pitchy brown, shining ; head rather narrower than the prothorax, 
finely punctured, short and convex in front, the clypeus rounded and 
hiding the lip; prothorax subelongate, broadest anteriorly, finely punc- 
tured; scutellum small, elongate; elytra with broad, stout carinz, the 
interstices nearly smooth or with a few almost obsolete punctures ; 
body beneath dark brown, shining, sparsely punctured, the punctures on 
the abdomen larger; legs and antennee ferruginous. Length 23 lines. 
I have asingle and not very perfect specimen of this species, which 
I received from W. W. Saunders, Esq. It is somewhat more massive 
than the others, except Sosylus crassus. 
* Sosylus Squirei. S. niger, subnitidus; capitis fronte sulcata; prothorace 
ovato, leviter punctato; elytris interstitiis lineatis minutis longitudinalibus 
impressis. 
Hab. Rio. 
In addition to the sulcated front, this species is distinguished by the depres- 
sion of the carine at the base of the elytra, and by the interstices, which are 
marked by numerous short and very minute longitudinal lines, giving them 
a roughish and somewhat opake appearance. Length 2 lines.
