e\ Portion of the wing beyond the fuscous band either fuscous or fuligi- 

 nous, spur reaching half way to the base. 



conspersa, new species. 

 e''. Portion of the wiiig beyond the fuscous band hyaline, spur reaching 

 two-thirds the distance to the base . .varkgnta, new species. 

 <i'. Wings entirely hyaline without fuscous band and colored disk, or the latter blue 

 with the fuscous band distinct or indicated by infuscated 

 nerves and cells. Fascia of the tegmina never solid ])ut 

 obviously made up of fuscous annuli often imperfectly 

 segregated. 

 h^. Fuscous l)and jjresent. Disk blue. Posterior tibise blue, with a light sub- 

 basal annulus Caeruleipennis group. 



(•'. I'rozonc <>f the pronotum strongly elevated and bilobate. Disk of the 

 wings faintly tinged with blue. Fuscous l)and narrow and 



indistinct caeruleipenaix Bruner. 



c'^. Prozone of the pronotum very little elevated and scarcely bilol)ate. Disk 

 of the wings deep blue. Fuscous band broad and distinct. 



cyaneipennis Bruner. 



h'\ Fuscous band wanting. The wing entirely hyaline. Posterior tibiae obscure 



greenish or brown. Posterior femora with the disk of the 



inner face black with two light bands on the apical half. 



Lower sulcus light with one preapical black band. 



AZURESCEXS C4ROUP. 



(•\ Scutellum of the vertex broad, scarcely longer than broad and about equal 

 in width to the diameter of the eye as seen from al)ove. 

 Process of the metazone acute azurescens Bruner. 



c'\ Scutellum of the vertex narrow, plainly longer than liroad and much less 



than equal in width to the diameter of the eye as seen from 



above. 



(P. Process of the metazone rounded. Basal fuscous liand distinct from the 



fuscous points of the immediate base. Larger, male more 



than 20 nun. long pseudo fasdaia Scudder. 



(P. Process of the metazone sharp. Basal fuscous band of the tegmina not 

 distinct from the spots of the immediate base. Smaller, 

 male less than 20 mm. long lauia Scudder. 



HYALINA group. 



Testaceous, entirely plain except for a few spots on the tegmina. 

 In size and appeai-auce much resembling Conozoa hehrensi^ but with 

 most of the characteristic features of that genus weakened or wanting. 

 It, however, forms the connecting link between that genus and Trlm- 

 erotropis. Scutellum of the vertex wide, about equal to or not much 

 less in width than the short diameter of the eye; median carina very 

 slight. Pronotum with the metazone one and a half times as long as 

 the prozone, with the process very obtuse angulate; lateral lobes with 

 a strong tooth on the posterior part of the lower border. Posterior 

 femora with the inner face light, with the usual dark bands much 

 weakened or wanting.
