152 NEOTROPICAL PSELAPHIDAE 



Group LIX 



This fifty-ninth group holds a single species in the neotropical area, 

 designata (Sharp), based on seven specimens from Las Mercedes, Guatemala. 

 The median frontal fovea is absent; both sexes have the fifth and sixth anten- 

 nal segments abnormal; male with a concave, and female with flattened, 

 metasternum; the vertex is medianly swollen or prominent between the inter- 

 ocular foveae, this extending anteriorly as an elevated area, but not reaching 

 the front. This prominent vertex is uncommon in the genus, and approached 

 in the neotropics only by carinifer Fletcher of Group 55.

Group LXIV new group 



This new group is erected for a single neotropical species, femoralis 

 Fletcher. Since the sixty-third group of Raffray has been elevated to a new 

 genus, femoralis could have been placed in this vacated spot, but the subse- 

 quent confusion would have been too great, and so Raffray 's groupings have 

 been left intact, there being no sixty-third group in the genus at present. The 

 essential features may be summated as follows: head with the vertex, front, 

 epistome, and mandibles normal for genus; the vertexal foveae not normal, 

 there being the usual two inter-ocular foveae, and the median anterior fovea 

 is very small on the depressed front between antennal bases, instead of being 

 subequal in size to the posterior pair; antennae normal; pronotum normal, 

 with a large, lateral, pubescent fovea each side and a smaller, nude fovea at 

 middle nearer base; each elytron with two basal foveae, and a discal stria not 

 reaching the middle; abdomen normal, first tergite with a pair of slightly 

 divergent basal carinae not reaching middle of segment and separated by one- 

 half the segmental width at base; metasternum flattened in male (only sex 

 known) ; legs not normal, intermediate tibiae armed with a strong spur on 

 the ventral face near apex, posterior femora greatly dilated, the dilation being 

 broadly and entirely excavated on the posterior face. As Fletcher pointed out 

 (1928) this species falls in Division V of Raffray (Groups 29-32) but does 

 not fit any of these on the character of the anterior cephalic fovea coupled 

 with the abnormality of the posterior femora.
