This very distinct species belongs to the group with the 

 mentum entire in the middle of its hind margin, and 

 which have the anterior tarsi with the terminal joints not 

 suddenly dilated, but differs from the two species hitherto 

 described, having the legs short and fossorial (C. Schaumii 

 and angularis), by having the legs comparatively much 

 broader and shorter, with the joints of the tarsi broader 

 than lonff. 



The following additional species of the genus Cremas- 

 tocheilus has recently been described, and is here added to 

 complete the bibliography of the genus: — • 



Cremastocheilus Wheeleri, J. Leconte, in Appendix

Brownish-black, not shining; head feebly punctured, 

 much dilated in front, broadly truncate, side angles 

 rounded. Prothorax subquadrate, a little wider behind, 

 sinuate on the sides; front angles acute, incurved and 

 densely hairy on the inner side; hind angles rounded, 

 expanded posteriorly; middle third of disk depressed, 

 covered with large shallow punctures ; lateral thirds 

 separated by a shallow impression more distinct near the 

 base and tip, very sparsely punctured, rather shining and 

 quite smooth behind the middle. Elytra with large shal- 

 low elongate punctures as usual; humeri shining; meso- 

 thoracic epimera not visible from above in consequence of 

 the posterior expansion of the hind angles of tlie prothorax.
