MAY, 1910. NOTES ON SOME CLERID^E WOLCOTT. 377 



with fine, rather dense silvery white pubescence. Antennae short, 

 stout, as long as the head ; apical joint obtuse at tip. Thorax broader 

 than long, very finely rugosely punctate; pubescence sparse, yellow- 

 ish; sides moderately dilated at middle; subapical constriction 

 strong, posteriorly gradually convergent; lateral foveae tranverse, 

 feeble ; anterior transverse impressed line distinct ; subbasal impressed 

 line deep, toward the flanks turning forward and extending to extreme 

 margin immediately behind the middle. Elytra much shorter than 

 the abdomen, densely, rather coarsely perforate-punctate ; sides 

 parallel, very sparsely pubescent but with more conspicuous, short, 

 semierect, silvery white hairs on apical half; apices obtusely, sep- 

 arately rounded, with a few well developed teeth, widely dehiscent 

 at suture. Legs moderately long, sparsely pubescent. Length 4.7 

 millim. 



Chinandega, Nicaragua. Collected by C. F. Baker. The type 

 specimen is in the collection of the Field Museum of Natural History.

A specimen of this species taken in Cuernavaca by Prof. Wickham 

 differs in no way from specimens collected in Arizona. It has not 

 been recorded as occurring elsewhere than in Arizona, whence came 

 the type.

In this species the elytra are black; at base of each elytron there 

 is a large red maculation extending to extreme lateral margin at the 

 shoulders but narrowly interrupted at the suture; this marking is 

 frequently prolonged posteriorly near the flanks, reaching in some 

 individuals the anterior margin of the tumid portion of apices. 



This species is an extremely variable one in coloration. In a long 

 series from Cuernavaca, Mexico, collected by Prof. Wickham, only 

 one example has the elytra entirely black; in this specimen the knees 

 are just touched with pale testaceous and the posterior side of an- 

 terior femora and basal joints of antennas are testaceous, this being 

 the nearest approach to an entirely melanotic form. In one ex- 

 tremely pale specimen the elytra are red excepting a longitudinal, 

 oval, sutural maculation at the middle and the apices which are
