another style of punctuation. The unicolored thorax as well 

 as the deeply emarginate clypeus will always enable this to be 

 separated from the darker and narrower phases of A. pul- 

 chcllus Herbst and its allies. 



Type in my collection, collected in the Chisos Mountains, 

 Texas, July 19, by Mr. H. A. Wenzel and kindly presented to 

 me by his father, Mr. H. W. Wenzel, after whom 1 take pleas- 

 ure in naming it. Two other specimens are now in the collec- 

 tion of Mr. Wenzel. 



Acmaeodera wheeleri n. sp. (PI. VII, fig. 5). 



Form elongate, subparallel and subcylindrical, head and prothorax 

 markedly bronzed, the latter with a small obscure yellow spot near 

 posterior angles, the elytra a deep blue, each elytron with two rows of 

 large yellow spots, the discal with four, one subbasal, one subapical 

 and two between equally distant from each other and the 

 nearest of these, the marginal with three spots which practically alter- 

 nate with the discal, the head and thorax clothed with short white 

 semi-erect squamulose hairs, the elytra with rows of short white semi- 

 erect setae, the latter arising from the punctures of the elytral inter- 

 vals. 



Head coarsely, shallowly, cribrately punctured, the clypeus rather 

 deeply emarginate, antennae with fifth joint suddenly dilated; thorax 

 two-thirds as long as broad, base truncate and apex bisinuate, broader 

 at base than apex and broadest at middle, sides evenly though slightly 

 arcuate, margin narrow and concealed from above, surface closely, 

 evenly, cribrately punctured, three basal foveae, one at middle, the 

 other at either side and midway between middle and posterior angles. 



Elytra twice as long as wide, as wide at base as the thorax, umbone 

 feebly prominent, sides slightly sinuate in front and gradually nar- 

 rowed from just beyond middle to apex, margins moderately serrate 

 posteriorly, disc convex, striae deeply impressed, especially near suture 

 and at the sides, and punctured with large approximate punctures, the 

 inner intervals slightly flattened, the outer convex, with single row of 

 fine punctures down the centre from which project short semi-erect 

 setae. 



Body beneath rather coarsely, closely punctured anteriorly, more 

 finely and sparsely over abdomen, densely clothed with white recum- 

 bent squamulose hairs, the anterior margin of prosternum truncate, 

 the last ventral with a short subapical carina. Length 9.5 mm., width 

 3 mm. 



This elegant and very distinct species likewise belongs with 

 the species having a truncate prosternal margin. It should be
