 of last segment. Second dorsal genital segment of female ob-

Black (including antennae, rostrum, and legs) ; base of first 

 and a subbasal annulation of fourth antennal joint, the depressed 

 lateral parts of the pronotal basal margin, a basal vitta, an 

 antemedian subtriangular spot, a postmedian fascia (at the base 

 of the narrow produced part) and the interior half of apical 

 margin of corium, posterior margin of mesopleura, a triangular 

 spot occupying posterior angle of metapleura, a spot on middle 

 acetabula, an oblong lateral spot at base of third, and a much 

 smaller subquadrate lateral spot at base of fourth and fifth 

 abdominal segments white; a lateral spot on head at inferior 

 margin of eyes, a longitudinal line between ocelli, a basal streak 

 to clavus, and apical border of prosternum obscurely luteous; 

 membrane fuscous, tinted with violet, somewhat less than its 

 apical half hyaline, trochanters dark ferruginous ; head, spines of 

 anterior pronotal lobe, posterior pronotal lobe (including spines), 

 scutellar spine, pleura, the first three antennal joints, underside 

 of rostrum, and legs sparsely, erectly, and rather longly palely 

 pilose. Head longer than pronotum and twice longer than broad 

 (excluding the strongly prominent eyes), impunctate, lateral 

 margins bluntly carinate between eyes and antenniferous tuber- 

 cles, slightly rounded between eyes and the short subparallel 

 neck, anteocular part twice longer than postocular part, distance 

 between antennae and apex of clypeus twice longer than that 

 between antennae and eyes, first joint of antennae one-third 

 shorter than head, second a little longer than first and third, 

 which are subequal in length, fourth slightly longer than second 

 and third combined, rostrum reaching a little beyond base of 

 venter, first joint as long as head, second equal in length to 

 first and nearly twice the length of the last two joints united, 

 fourth three times longer than third. Pronotum (excluding 

 humeral spines) slightly narrower than head (including eyes) 

 and almost as broad as long, anterior lobe impunctate apart 

 from scattered points near the apical margin, with two stout 

 and rather long, divergent, conical, apically attenuated spines; 

 posterior lobe twice longer than anterior lobe, rather thickly 

 and coarsely punctate, basal margin depressed in front of elytra, 

 humeral spines as long as the anterior spines, directed obliquely
