male with a very long basal joint, a short compressed second joint, 

 the third joint swollen and excavated near the apex, the fourth joint 

 swollen and excavated in the basal portion, remaining joints long and 

 slender (the last three missing), pale yellow brown with the first 

 three on the outside touched with deep piceous. In the female the 

 third joint is approximately equal to the fourth. Prothorax nearly 

 twice as wide as long with slightly rounded sides and a deep transverse 

 sulcus, entu*ely yellowish brown, nearly impunctate. Scutellum 

 pale. Elytra wider in apical half, rather depressed with a short 

 intrahumeral sulcus and feeble costae, the intervals being obsoletely 

 geminate-striate punctate; pale yellow brown with reddish brown 

 markings on the humerus, about scutellum and a little way down the 

 suture, a broad fascia before the middle not extending to the suture 

 and a rounded half circle of two spots before the apex on each elytron. 

 Body beneath yellow brown with the breast deep reddish brown, 

 legs entirely pale; first tarsal joint in all legs unusually long, anterior 

 coxal cavities open, claws appendiculate. Length 8 mm. ; width 4 mm. 



Type, male, USNM 66855, from Piedra Negra, Costa Rica, 

 collected bj^ vSchild and Burgdorf; paratype, female, from same col- 

 lection. 



Remarks: The second specimen, a female, has a slightly different 

 coloration, the entire head being yellow brown, the markings on the 

 elytra are more indistinct, but of the same pattern, and the underside 

 is entirely pale. A third specimen, also a female, from Waldeck, 

 Costa Rica, collected by C. H. Ballon, has also a pale head and under- 

 surface, but more distinct reddish-brown elytra! markings of similar 

 pattern. Still another male, from Lolola, Costa Rica, collected 

 June 22, 1957, on cacao by M. J. Stelzer, is of similar coloring. In 

 all of these specimens the elytral sculpture is like that of the type, 

 and in this respect differs from denticornis in which the costae are 

 very distinct and the punctation deep and coarse. The third antennal 

 joint in the female is about equal to the fourth, whereas in denti- 

 cornis it is a little longer in most specimens.

 fascia and another before the apex, the former sometimes enclosing 

 a pale spot; legs, undersurface and antennae pale.
