middle of each elytron, and a longer median one near the flanks; 

 in this form the humeral markings are distinctly quadrate (the um- 

 bones obscurely testaceous) and the fascia is generally rather nar- 

 rower than in the specimens with elongate humeral markings; this 

 form was taken by the writer in some numbers on Acacia and Dios- 

 pyros at Brownsville, Texas.

Similar in form to mixta; pale yellowish; head, thorax, and 

 elytra with variable markings; feebly shining; moderately clothed 

 with not very dense, semierect, pale hairs. Antennas ten-jointed, 

 entirely pale or with three apical joints black. Head varying from 

 rufous testaceous to black, usually black with inner margin of the 

 eyes, large frontal maculation, labrum, and other parts of the mouth 

 testaceous; the mandibles black; very coarsely and densely punc- 

 tate. Thorax very slightly longer than broad; apical and posterior 

 angles obtusely rounded; sides at apical third nearly straight, be- 

 hind the middle acutely dilated, suddenly and strongly constricted 

 before base, which is much narrower than apex ; convex, surface even ; 

 disk coarsely, rather densely, flanks very densely, somewhat rugosely 

 punctate; entirely pale or pale with two discal slightly converging 

 black vittae, or with several small black spots, those near base trans- 

 versely placed and sometimes confluent. Elytra slightly more than 

 two and one-half times as long as thorax; sides subparallel; apices 

 conjointly rounded; punctures coarse, deep and seriate, extending 

 from base to apical third, obsolete at apex, pale yellowish; each 

 elytron with a large quadrate or lunate humeral spot (sometimes 

 wanting) and at apical fourth a large, more or less rounded discal
