viously emarginate ; surface strongly convex, polished ; coarsely, sometimes 

 confluently, punctate. Scutellum convex and polished as in the allied 

 species, impunctate; medially obscurely transversely wrinkled. Elytra as 

 in fenestratus, broad, convex, including the embolium coarsely fusco- 

 punctate; base of cuneus sometimes punctate. Membrane obscurely bi- 

 areolate. Rostrum reaching the intermediate coxae; first segment attain- 

 ing base of head. Sinistral clasper of male with a long acute porrect basal 

 tooth as in grandis, the ventral member in the type concealed but appar- 

 ently very acute at apex and passing beyond the dextral clasper which is 

 of the usual form, ovate at base and produced in an acute point. 



■Color testaceous white, coarsely fusco-punctate and maculate ; head 

 tinged with yellow, infuscated; vertex and front with four or five trans- 

 verse arcs and margined with the same color, deepened to piceous above 

 the antennae ; clypeus pale, bilineate with piceous, the "sutures of the cheeks 

 also piceous. Antennae with long scattering pale hairs ; segment I obscurely 

 lineate, as long as the greatest length of the eyes; II as long as pronotum, 

 slightly clavate and infuscated on apical third; III and IV infuscated. III 

 longer than I, IV shorter. Pronotum slenderly edged with pale, the fuscous 

 punctures usually forming a cloud either side of the disk ; anterior margin 

 forming a broad testaceous collum ; callosities contiguous, black, polished, 

 bordered anteriorly by a pale sinuate vitta. Scutellum whitish with a dark 

 spot either side, basally contiguous. Elytra with a large piceous cloud at 

 apex produced basally to cover the disk of the corium and apex of the 

 clavus ; cuneus pale, piceous at apex ; membrane enfumed, with a pale 

 band across at apex of areoles, the veins piceous at base and apex. Legs 

 pale, the femora mostly piceous. Beneath more reddish, invaded at times 

 with piceous; anterior coxal cavities and osteolar region white. 



Described from one male and ten female specimens taken by 

 me in the Garden of the Gods at Manitou, Colo., July 19, 1900, 

 and July 25, 1903, and five specimens from Colorado, received 

 from Mr. H. H. Knight. This is the species I formerly deter- 

 mined as Camptobrochis cerachates Uhler but a study of the 

 type in the museum of the California Academy of Sciences 

 shows the latter to be a paler form common in California more 

 allied to fiihescens.
