Sept.-Dec, igiS.l ScHAEFFER : OSTOMIDTE. 195 



in the Leconte collection which I examined and in the collections of 

 Dr. Horn and the American Entomological Society, kindly examined 

 at my request by Mr. Chas. Liebeck, all have the anterior tibire mar- 

 gined and the outer margin with one or two teeth. They all came 

 undoubtedly from the original lot collected by Crotch in the Mohave 

 desert. 



Temnochila acuta Lee. 



This is a distinct species and not synonymous with viresccns as 

 given in our lists. The head is dull, the abdominal segments finely 

 alutaceous, the sensitive spaces of the joints of the antenna! club are 

 larger than in any of our other species and the posterior margin of 

 the prosternum in most of the specimens is more convex and ap- 

 parently feebly produced at middle. The males have the ventral seg- 

 ments at sides with a rather finely and closely punctate area which 

 extends almost to middle and with very few larger punctures inter- 

 mixed. 



This species occurs also in Mexico and was considered by Dr. 

 Sharp in the " Biologia " to be Fabricius' viresccns. While there is 

 a possibility that viresccns is wrongly identified it is also possible that 

 Dr. Sharp's identification is wrong as he gives no tangible reason why 

 this species should be the true viresccns of Fabricius. Drury who 

 sent the specimen to Fabricius, received his American insects either 

 from North or South America as far as I know, but Dr. Sharp did not 

 give any South American locality for his viresccns. If the specimen 

 sent to Fabricius came from North America it was collected on the 

 Atlantic coast and could be nothing else than our common species 

 which occurs from Long Island to Florida. 



Fabricius gives America only as locality and his rather vague 

 description might fit almost any metallic green species of Temnochila. 

 However, the size he gives — " triplo major L. caraboidcs" — restricts 

 it only to the larger species. I have seen a great number of speci- 

 mens of our common species but all are not nearly three times as 

 large as Tenehroides mauritanica, which is the same as Fabricius' 

 Lucamis caraboidcs, except one specimen from Florida which is about 

 19 mm. long. The examination of the type would settle the matter, 

 but unfortunately I was unable to locate it. Mr. Champion and Mr. 

 Arrow wrote me that the type is not in the British Museum collection
