short black hairs, scmi-recumbent near the base and erect behind the 

 middle. Body beneath slightly darker than the upper surface. Length 

 .25 inch ; 6.5 mm. 



This species may be distinguished from mhiimum by the form of 

 thorax. The head is also less elongate, and the nia.xillary prolon<ic;i- 

 tions about one and a half times the length of head. In the 

 preceding species they are longer than half the entire length of 

 body. 



Specimens were collected by Dr. A. L. Heerman in Texas. 



G. nitidum, u. sp. — Form slender, color yellowish testaceous, shining. Head 

 shining, densely punctured within the eyes, vertex smooth. Thorax campanu- 

 late, slightly longer than wide ; surface smooth, shining with few fine widely 

 scattered punctures. Elytra shining with fine distantly placed punctures ar- 

 ranged in irregular striae. Body beneath pale brownish, legs yellow. Autennee 

 black, first and sometimes second joint pale. Length .20 inch ; 5 mm. 



Differs from all our species by its shining surface, llecent speci- 

 mens have but few rather longer hairs than either of the preceding 

 species. The head is less elongate, the hind angles more rounded and 

 the maxillary prolongations scarcely longer than the head. 



.'Specimens were collected in Owen's Valley, California.

From all the preceding species it differs in color, having the entire 

 body black except the thorax, which is yellow. It appears to resem-

 in study I append the original descriptions.

Without wishing to express a definite opinion regarding the identity 

 of the two, it must be acknowledged that the two descriptions approxi-
