excavated. Jletaatermim about half the length of 1st abdouiiual 

 segment, very narrow between four posterior coxae; episterna very 

 narrow in middle. Abdomen moderately large, sutures distinct; 

 two basal segments large, 1st slightly longer than 2nd, intercoxal 

 process wide, almost truncate, apex raised in middle, three apical 

 segments small, apical slightly shorter than 2nd and noticeably 

 longer than the intermediates combined. Lec/s rather short and 

 thick; femora feebly grooved and obsoletely dentate, posterior 

 terminated just before apex of abdomen; posterior coxa; transverse, 

 almost touching elytra; tibiai rounded, straight beneath, somewhat 

 sinuous above and thickened at apex, terminal hook short and 

 stout, each with a small subapical tooth on each side of which is 

 a tuft of elongate setaj; tarsi rather slender, 3rd joint short, not 

 much wider than 2nd, deeply bilobed, claw-joint moderately 

 elongate; claws feeble. Briefly elliptic, convex, apterous. 



A remarkable genus, the true position of which I believe to be 

 close to Ptiepholar. M. Lacordaire places each in a separate 

 "groupe," the latter in the Ithy2)orides, the former in the Crypto- 

 rhynchides vraia. I have not seen the original description. 



Hybo.moepiius melanosomus, 8. it J., I.e. p. 302. 



Black, softly shining; antennae and tarsi dull reddish-brown. 

 Pi'othorax with a very minute and indistinct scale in each 

 puncture, sides and base margined with ochreous scales. Elytra 

 with small scattered ochreous scales on apical half and condensed 

 •on sides about apex and on the rtth interstice beyond the middle. 

 Each puncture of under surface with a small scale. Tibife and 

 apex of femora with ochreous scales 



Head with small shallow punctures. Rostrum thin, subparallel, 

 shorter than prothorax and more than twice the length of head; 

 punctures .somewhat similar to those on head but less rounded, 

 and here and there interrupted by small impunctate spaces. 

 Funicle with first joint the length of 2nd 4th, 2nd equal to 

 3rd-4th, .Tth-7th slightlj' transverse. Prothorax transverse (8 

 X iOh mm.), with a ver}^ feeble impression in middle of base; with
