feebly impressed ; eyes pale, more prominent laterally in the male than in the lemale: 

 antennie very stout, all the joints of nearly equal thickness, the second joii* about as 

 long as the eye and pronotum united, the third and fourth short, both contracted at 

 base, the fourth shortest almost at tip ; rostrum pale rufopiceous, reaching to tip ol 

 the middle coxa:. Scutellum paler brown, yellowish at tip, moderately convex, 

 transversely impressed before the base. Legs piceo-fulvous, a little embrowned at 

 the points of articulation, the posterior acetabular flap white. Pleural ])ieces fulvous, 

 polished. Plemelytra pale fuscous invested with erect hoary pubescen.e ; the clavus 

 fulvous, a little embrowned at base, corium witli a triangular white spot at base, a 

 pale costal margin and a white oblique band across the liroad apex : cuneus short, 

 triangular, fuscous, margined cxterii)rly and at tip with wliite ; membrane dusky, 

 darker at base, venter piceous, sericeous pubescent, fulvous in the basal angle. 



Length to tip of membrane 4 mm.; to end of venter 3 J mm. Width of base of 

 pronotum a little less than l mm. 



Two specimens collected in the neighboiliood of San Francisco, were 

 kindly given to me by Mr. James Behrens, to whom I desire to dedicate 

 this species as a slight recognition of the many services he has done in 

 several branches of Entomology. 



The thick texture of the integuments, besides the exceptionally stout 

 antennit, and bent hemelytra, will abundantly se{)arate this species from 

 all its allies thus far recognized. 



Diommatus, new genus. 



General outline oblong elliptical. Head viewed from above nearly 

 triangular, the face almost vertical, moderately tumid in front, longitudi- 

 nally indented and excavated above. Superior cheeks short, tapering 

 towards the tip, inferior cheeks wide, oblong, prominent, blunt at tip. 

 Occipital edge carinate. Eyes large, prominent almost spherical {(^), 

 vertical sub-oval Q. Tylus short, very prominent, cylindrico-convex ; 

 curved beneath. Antennce about as long as the wing-cover, slender, the 

 joints gradually decreasing in thickness from the basal to the third one ; 

 the basal stout, abruptly contracted at base, but little longer than the 

 apical one, the latter being of the same thickness as the third, the second 

 long, cylindrical, equal to the third and fourth united. Rostrum slender, 

 the basal joint a little longer than the throat. Pronotum trapezoidal, 

 nearly flat, shorter than the width at base, the callosities prominent, and 

 breaking the continuity of the oblique, blunt lateral margin. Scutellum 

 moderately convex, bluntly acuminate at tip. Hemelytra long and nar- 

 row, thin, pubescent, the cuneus long, slender and acute at tip, with the 

 outer margin nearly straight, the inner margin concave, and the base very 

 slightly incised. The membrane also long, with the principal cell long 

 and rather narrow. Legs long, slender, the posterior femora stout, com- 

 pres.sed, curved ; posterior tarsal joints moderately long, the basal and 

 middle joint subequal, the apical one longest. Abdomen narrow and not 

 distinctly contracted at base.
