May, 1910. Notes on Some CLERiDiC — Wolcott. 361 



tate. Elytra subparallel ; humeri very prominent ; basal tubercles 

 nearly obsolete; basal striga feeble, yellowish; surface moderately 

 coarsely and very densely punctate, more feebly and sparsely at apex ; 

 a broad, black, slightly ante-median fascia extending from reflected 

 portion of lateral margin to the suture, where it is narrowly inter- 

 rupted; anterior and basal margins of fascia slightly irregular. 

 Ventral surface and abdomen rather finely and sparsely punctate. 

 Length 7.25 millim. 



This species appears to be quite distinct from any other occurring 

 in the fauna treated of in this paper. The median dark fascia is 

 equal in width to half the length of the elytra and as a whole is sit- 

 uated mostly before the middle, in other words the basal one-sixth 

 and apical one-third of elytra are red, the fascia occupying the inter- 

 vening space.

A single specimen was taken by Prof. Wickham at Cuemavaca. 

 As indicated by the synonymy this is a variable species in coloration. 

 The Cuemavaca specimen has the head, under surface, and legs black, 

 the tarsi obscurely testaceous, the thorax reddish, somewhat infuscate, 

 especially across the middle. The elytra fasciae are about as figured 

 by Spinola (pi. 25, f. i) except that the lunate median fascia, while 

 interrupted at the suture, is confluent with the common triangular 

 shaped maculation. The apical portion of elytra is black, with an 

 oblique ante-apical fascia interrupted at the suture; the space 

 between the ante-apical and median fascia and the anterior margin 

 of the latter black; basal portion red. The three terminal and the 

 basal joints of the antennae red, the intermediate joints gradually 

 becoming darker from the club to the base. The specimen is 7.8 

 millimeters in length. 



Clerus salvini Gorham.

Two specimens of this species labeled "Mex.," without other data, 

 have been in the possession of the writer for a number of years. This 

 species has been recorded only from Guatemala and Costa Rica.
