Temnochila prosternalis new species. 



Elongate, subparallel ; color of upper and under surface metallic green, 

 blue or purple; antennae and palpi piccous. Head shining, rather densely and 

 relatively coarsely punctate especially in front ; front with a deep, longitudinal 

 median impression. Prothorax densely and rather coarsely punctate on the 

 disk, less densely near lateral margin ; anterior angles acute, slightly pro- 

 duced ; lateral margin feebly rotundate-angulate slightly behind middle ; basal 

 angles obtuse, not prominent. Elytra with rather coarse deep and closely 

 placed punctures ; intervals with slightly smaller punctures. Presternum with 

 moderately large not densely placed punctures, behind the coxae with a more 

 or less distinct transverse impression. Metasternum punctured as the pro- 

 sternum. Abdominal segments shining, with moderately large punctures ; 

 males with a very small area of finer punctures intermixed with larger punc- 

 tures at sides of each segment. Length lo— 11.25 'iirii- 



Williams, Arizona. (Barber & Schwarz coll.) 



The type is in the Nat. Musettm collection, paratypes in the collec- 

 tions of the Museum of the Brooklyn Institute and in Prof. Wick- 

 ham's collection. 



This species looks very much like small specimens of vircsccns 

 var. cJilorodia but has a much more densely and relatively coarsely 

 punctate head, prothorax and elytra and the prosternum behind the 

 coxae at apex more or less distinctly impressed. 



It is apparently closely related to fraudulenta from Mexico and 

 planicollis from Guatemala. The metallic green species in this genus 

 differ much individually in color, sculpture, etc., and it is possible that 

 these three species are all one. 



Temnochila obscura Reitt. 



This species does not occur in North America. 



Tenebroides crassicornis Horn. 

 Trogosita plcuralis Horn. 



This is not a variety of mauritanica but a distinct species. It is 

 always smaller, relatively less elongate and the joints of the antennae 

 are shorter and more closely placed than in mauritanica. T. pleuralis 

 Horn does not seem to differ except in coloration. 



Tenebroides sorer Duv. 

 T. foveata Blatch. 



I have several specimens from Florida (Key Largo and Key 

 West) which agree closely with the description of the West Indian 

 T. soror. Blatchley's foveata is the same thing.
