types of TJujreopns cingalafiis reveals that Packard had confused 

 hilaris with that species. He remarks, on p. 357, that the 9 tie- 

 scribed by him is referred doubtfully to cingnlatus on account of the 

 difference in coloration. Strange to say, however, one of the original 

 types of the 9 <l<>es not possess tlie color marks about which Packard 

 speaks, and belongs to ciiKjulatKS 



13. Group tilUdive)drl><. 



Pronotum above large, convex, not crested, rounded at the sides ; 

 middle segment above divided into two smooth convexities ; ocelli 

 in an almost equilateral triangle ; pygidium ( 9 ) narrowed apically, 

 strongly depressed or excavated ; wings in all our species with several 

 dark s})ots ; abdomen, as in the two preceding groups, spotted ; an- 

 tenniie and fore legs of males simple. 



This group represents in America the genus Blcjjharijxis St. F. 

 et Br.

9 . — Head luort' distinctly and less closely punctured thau in confertu.1, particu- 

 larly the front and vertex, and ajjpears more transverse than in that species, im- 

 pressed line running from frontal depression to fore ocellus strong and wide ; 

 pronotum at the sides sub-rounded, and short ; dorsulum punctured like the ver- 

 tex ; scutellum sparsely punctured anteriorly, more closely so on posterior portion ; 

 episternal suture of mesopleui-ae very heavily foveolate, more so than in confertus : 

 base of the enclosure of middle segment with the usual transverse row of large 

 fovcEe, the central furrow broadened basally, longitudinally ridged, the outer 

 furrow forming the enclosure much more heavily foveolated than in the species 

 mentioned above, posterior face coarsely rugose apically, the lateral ridgi-s strong 

 and margined outwardly by a strongly foveolated furrow ; abdomen finely and 

 sparsely punctured above, except the first segment, which is impunctate, and, 

 excluding the pygidium, the punctures are most distinct and closest on fifth seg- 

 ment; pygidium as usual. Black, including the mandibles and episternum meso- 

 pleuralis; scape entirely, pronotum, tubercles, line on scutellum anteriorly, spot 

 on each convexity of the enclosure of middle segment, tips of fore and medial 

 femora, tibise except within and apex of hind pair, first joint of tarsi, a trans- 

 verse spot on each side of dorsal abdonnnal segments 2-4, and a band on the fifth, 

 somewhat narrowed medially, pale yellow ; clyiieus and inner orbits beneath with 

 dense, silvery i)ubescence, that on the cheeks sparser; wings as in confertus, but 

 the dark spots are moi-e distinct ; head and thorax above with pale fuscous pu-
