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 Tosteyoptera, as very 

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

 by any essential characters. 



DIPIvOTAXIS KIRBY. 



D. obscura, oblonga nigro-picea, subnitida, capite hemihexagono, dense punctato, antice late 

 emarginato, margine anguste reflexo, sutura frontali profunda, vertice late bifoveato, thorace

 subrectis, raarginc laterali reflexo, ad angnlos latiore irapresso, elytris punctatis, tricostatis, tibiis 

 anticis tridentatis. Long. &quot;45. 



One specimen from the Black Hills : Dr. Hammond. Kesembles 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 foveae 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 

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

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