72 COLEOPTERA RHYNCHOPHORA. 



scarcely visibly punctate, intervals a little more than twice as wide as 

 the striae, second and third a little wider and fully three times as wide 

 as the striae ; interstitial punctures fine and not very close on the inner 

 intervals, on the outer intervals coarser and closer and about one-half 

 as wide as the intervals. Beneath coarsely closely punctate, the abdo- 

 men more sparsely so, especially at the middle ; prosternum nearly flat, 

 separating the coxae by slightly more than half their own diameters. 

 Legs moderately punctate. Length, 3.75 mm. ; width, 1.7 mm. 



Type. — From Ormsby County, Nevada (Baker). 



The type is a male with abdomen at base strongly im- 

 pressed. The prothorax being more than half as long as 

 the elytra would lead the student to place this species under 

 "16" in Casey's table; but the other characters are more 

 in harmony with the following species and lead us to " 22 " 

 in the neighborhood of sparsa. The latter is smaller (2.8-3 

 mm.), dark rufopiceous in color, with distinctly sparser punc- 

 tuation both of the pronotum and elytra. 



PYCNOBARIS Csy. 

 P. iiigTOStriatiis n. sp. — Oblong ovate, black, shining, clothed 

 rather densely with robust parallel truncate or subtruncate recumbent 

 white scales, which are on the average from three to four times as long 

 as wide. Head minutely sparsely punctate. Beak robust, three-fourths 

 as long as the prothorax, its anterior outline strongly evenly arcuate, 

 posterior outline straight for the greater part of its length when viewed 

 in profile ; punctuation close, forming rugae at sides, squamose laterally 

 toward the base. Antennae nearly as in pruinosa. Prothorax very 

 nearly as long as wide, sides convergent and nearly straight from base 

 to apical fifth, then strongly rounded to the well marked apical con- 

 striction ; surface densely coarsely punctate, the punctures about one- 

 third as wide as the scutellum and nearly in mutual contact. Elytra 

 about one-third longer than wide, three-fifths longer and at the humeri 

 about one-sixth wider than the prothorax, sides very feebly conver- 

 gent from the humeri, discal striae coarse and deep, feebly punctate, 

 glabrous ; intervals but little wider than the striae, irregularly rather 

 coarsely punctate and densely squamose, the white vestiture contrast- 

 ing strongly with the black striae. Beneath densely punctured and 

 squamose. Prosternum flat, nearly as wide between the coxae as the 

 coxal width ; transverse impressed line or sulcus deep, midway between 

 the coxae and the front margin. Length, 3.6 mm. ; width, 1.75 mm. 



Type, — From Palm Springs, California (Fenyes). 



Readily distinguished from our two previously described 

 species by the coarser glabrous striae and narrow intervals 

 of the elytra. The vestiture is much denser than in pruinosa.
