larger than seventh, tenth less transverse; basal discal carinae of 



first tergite one-third of segmental length foveifrons 



Antennae with segments eight, nine, and ten less transverse, much 

 larger than seventh, forming a marked club; basal discal carinae

BRAXYDA (Raffray, 1904) 



This is a small genus of two Bolivian species, related to Bryaxina, and 

 separated by the key characters noted previously. The males have the second 

 tarsomere of the anterior tarsi expanded and supplied below with a brush of 

 setae. Pronotum with a minute, punctiform median fovea near base and no 

 lateral foveae. Elytra with a strong discal stria extending to the middle of 

 elytral length ; each elytron with two basal foveae, the sutural and discal. First 

 tergite much longer than second, with a pair of basal discal carinae one-fourth 

 of the segmental length and enclosing one-third of the segmental width. Male 

 pygidium very large, subhexagonal, curved ventrally. Fourth segment of 

 maxillary palpi truncate at base, regularly fusiform as in the genus Reichen- 

 bachia; third segment small, triangular. Middle coxae subcontiguous, allow- 

 ing the mesosternum to be seen between them as a thin lamina. 



The two species may be separated as follows: 



Key to the Species 



Male with segments of antennae III, IV, and VI short; V three times 

 wider than long; VII two times wider than long; VIII quadrate; 

 IX and X obconical-truncate, wide, slightly crescentric, tenth two 

 times wider than long; XI fusiform; metasternum broadly concave; 

 middle legs with trochanters lunate, produced mesially into a thick, 

 acute tooth ; middle femora inflated, with the ventral face obliquely 

 notched to produce an apically directed tooth ; middle tibiae with a 

 large, strongly curved spine at internal-apical angle. Female with 

 antennal segments VIII, IX and X quadrate; metasternum not con- 

 cave; middle legs simple. 2.6 mm hamata
