bent at about the middle and running thence almost vertically over the 

 crest distinctly behind its base ; the surface behind this vitta darker brown ; 

 median dorsal spot lengthened downward about one half way to the margin, 

 pushed well back by the greater elevation of the crest anteriorl}'; posterior 

 vitta nearly obsolete, placed as usual at the posterior sinus. Metopidium 

 with a ferruginous or black mark above each eye. Elytra hyaline with the 

 narrow apex infuscated. Tergum brown with the usual pale base. In the 

 male the crest is lower, the posterior process is a little shorter, the anterior 

 oblique vitta is scarcely defined and the tergum is black with a narrow pale 

 base. Face in both sexes rather even, loras scarcety distinguished from the 

 cheeks; ctypeus prominent, convex, produced for a third of its length be- 

 yond the lorae, and strongly incurved in the female; much less produced in 

 the male. Length 8 mm. 



Described from one pair in the Cornell University collec- 

 tion taken in Arizona. I have adopted the MS name given to 

 this species by Dr. Uhler. This insect has a superficial resem- 

 blance to Smilia camehis but the crest is much less elevated and 

 is highest at about its middle, and it differs generically in hav- 

 ing a cross vein between the two interior longitudinal nervures. 

 In the form of crest Smilia fasciat a is just about intermediate 

 between this species and Smilia camelus. 



7. Cyrtolobus sculptus Fairmaire. PI. 2, fig. 20. 



Nearest to discoidalis but more elevated anteriorly and the 

 vittse more oblique. Pronotum moderately elevated; crest 

 rounding anteriorly to the highest point a little behind the 

 humeri ; thence the dorsal line is almost rectilinear to the apex. 

 Anterior oblique vitta straight, sometimes dilated anteriorly at 

 base, the surface before it pale ferruginous with a brown ray or 

 curved vitta on either side of the metopidium ; behind this 

 oblique line the surface is darker brown or sometimes blackish 

 next the line; median dorsal spot subhyaline, longer on the 

 carinate edge than high ; posterior vitta narrow, oblique, almost 

 connecting with the anterior at base. Head sparcely punctured ; 

 clypeus and lorae large, their basal suture acutely angled ; apex 

 of the clypeus strongly incurved beyond the lorae; margin of 

 the cheeks distinctly sinuated. Elytra hyaline; brown and 

 punctured at base ; apex a little smoky. Beneath ferruginous ; 

 legs brown, oviduct black at bass, rufous at apex. Length 6 mm. 



Of this species I took three females at Milan, Ohio, in Sep- 

 tember 1905. They are a little smaller and darker than indic- 

 ated in the description by Fairmaire but of all the species
