I had very little opportunity to do anything with this species, 

 except prepare a sketch from which the wood cut above cited was 

 made. It is even doubtful if the species belongs to our fauna. The 

 type is in the museum of Magdalen College, Oxford, England. 



One species (blanda), constitutes section B. It has very broad 

 elytral markings, very badly defined in the two specimens I have 

 seen. The humeral lunule unites with the basal spot, the median 

 band is sinuous as in cuprancens, or even more so. The female has 

 no tooth near the tip of the elytron, and the sinuation is very feeble. 

 (Fig. 24). This species is a lead in the direction of the Gabbii 

 group. 



Section C contains two species which diflFer from all the others in 

 the group, in the absence of the basal spot, and by the markings 

 being usually disconnected along the margin. 



C sperata, Lee. — Dark bronze; labrum with median tooth; median band 

 with long, moderately sinuous longitudinal portion; anterior end of apical 

 lunule moderately prolonged. 



J/a/e.— Elytra slightly sinuous near the tip, the latter acute with sutural 

 spine. 



Female. — Elytra rather strongly sinuous, and with a distinct angulation. Tip 

 less prolonged than in male but with sutural spine. 



C nevadica, Lee. — Coppery bronze, labrum without median tooth. 

 Elytral markings widely disconnected along the margin. Median band with 

 rather short, feebly sinuous longitudinal portion. Apical lunule not prolonged 

 in front. 



Male. — Elytra broadly subsinuate near the tip. 



Female. — Elytra strongly sinuous, the anterior angle of the sinuation 

 rounded. 



For fuller description and figure, see (Trans. Am. Ent. Soc, 1875, 

 p. 159). 



Section D contains two species especially characterized by the 

 entire abdomen being punctured, and covered at middle with similar 

 pubescence as at the sides. 



C hirtilabris, Lee. — Labrum rather densely clothed with prostrate 

 hairs. The markings are similar to those of gratiosa, but less extended, so 

 that the sutural dark space is broader. 



Male — Elytra very feebly sinuate, tip obtuse. 



Female. — Sinuation deeper, limited in front by a distinct angulation, i p 

 obliquely truncate. (Fig. 25).
