NORTH AMERICAN BUPRESTID BEETLES 297 



DISTRIBUTION 



Material examined : 



Texas: Victoria, April 18-May 3 (J. D. Mitchell). Kerrville, May 30-June 2 

 (F. C. Pratt). Chamberlin (1926) records it also from Davis and Flotonia, 

 Tex., and from Onaga, Kans. ; the latter record is probably from an incor- 

 rectly identified specimen, and probably should be impexus Horn. 



Variations. — The color varies from bronzy brown to cupreous 

 brown, and the length from 6 to 7.5 millimeters. In some examples 

 the pubescent spots on the elytra are scarcely visible, whereas in 

 others they are rather distinct. 



Host. — Unknown. 



This species seems to be rare in collections and very few examples 

 have been examined. Horn described the species from five examples, 

 all of which are from the Belfrage collection, and without definite 

 locality labels. The lectotype No. 3489 in the collection of the 

 Philadelphia Academy of Natural Sciences is a female. The four 

 other examples mentioned by Horn in his description as being in the 

 National Museum are badly confused, and represent three different 

 species, two of which are abjectus Horn (male and female), one is 

 impexus Horn, and the other one is addendus Crotch. 



The species is not conspicuously marked, but among those in which 

 the antennae are serrate from the fifth joint it may be known by the 

 very convex pronotum, with a feeble median depression, absence of 

 prehumeral carinae, the feeble pubescent spots on the elytra, and the 

 sides of the prosternal process expanded behind the coxal cavities.

Male. — Form moderately robust, subcylindrical, vaguely flattened 

 above, and feebly shining ; head cupreous, with a more or less aeneous 

 tinge; pronotum dark brownish cupreous; elytra reddish cupreous, 

 and ornamented with whitish pubescent vittae; beneath cupreous, 

 with an aeneous tinge, and more shining than above. 



Head with the front rather wide, feebly convex, and slightly wider 

 at top than at bottom, the lateral margins feebly expanded from 

 bottom to top, and with a rather broad, shallow, longitudinal depres- 

 sion extending from occiput to epistoma, behind which the surface 

 is transversely depressed; surface obsoletely granulose, rather 

 densely, coarsely punctate, coarsely, irregularly rugose, and sparsely 

 clothed with long, recumbent, whitish pubescence; epistoma trans-
