Ancylomjcha 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. Ill), does not differ from Lachnosterna 

 by any essential characters. 



DIPLOTAXIS KIRBY. 



D. obM'iira, oblonga nigro-picea, subnitida, capite hemihexagono, dense punctate, antice late 

 emarginato, margine anguste reflexo, sutura frontal! profunda, vertice late bifoveato, thorace 

 brevi dense punctate, medio paulo latiore, lateribus rotundatis, angnlis anticis subacutis, posticis 

 snbrectis, 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. 

 brevicollis 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 Dlplotaxes, 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 diifers, nevertheless, remarkably from the other genera by the nine-
