Ancylonycha lanceolata Lacordaire, Gen. Coleopt.. Ill, 285. 



Throughout Kansas, extending into Eastern New Mexico and Upper Texas. 

 The male is winged, while the female is apterous. The genus Tostegoptera, as very 

 properly observed by Lacordaire (Gen. Col. HI), does not differ from Lachnosterna 

 by any essential characters. 



DIPIiOTAXIS KiRBY. 



D. obsciira. oblonga nigro-picea, sulmitida, capite lieinihexagono, dense punctato, antice late 

 emargiuato, niargine angnste reflexo, sutura frontali profunda, vertice late bifoveato, tliorace 

 brevi dense punctato, medio paulo latiore, lateribus rotundatis, angulis anticis subacutis, posticis 

 subrectis, margine laterali reflexo, ad angulos latiore impresso, elytris punctatis, tricostatis, tibiis 

 anticis tridentatis. Long. '45. 



One specimen from the Black Hills : Dr. Hammond. Resembles somewhat D. 

 brevicoUis Lee, but is more densely punctured, with the sides of the thorax more 

 rounded, and more deeply impressed at the angles : the two foveaj of the vertex, 

 if a constant character, will serve easily to distinguish it.

A genus belonging to the Diplotaxes, and having the characteristic form of abdo- 

 men of that tribe, viz., the 5th ventral segment united without suture to the 

 propygidium, with the spiracle each side midway between the anterior and posterior 

 margin. It differs, nevertheless, remarkably from the other genera by the nine-
