392 MEMOIRS ON THE COLEOPTERA 



Female without a pygidial stylus. Body oblong-suboval, rather stout, 

 obscure ferruginous, with the elytra clearer rufous and with the 

 large yellowish scales abundant, covering most of the surface (cf), 

 or blackish, with the elytral scales small, blackish, sparser and more 

 lineiform, except in a central cluster of pale scales on each (9); 

 head small, with very minute stiff hairs,' the clypeus large, flat, 

 transversely oval, very feebly sinuate medially at apex; antennal 

 club small in both sexes; eyes very moderate; prothorax as long as 

 wide to very slightly wider, the sides converging from base to apex, 

 feebly, subevenly arcuate and unevenly serrato-crenulate, feebly 

 reflexed anteriorly; surface very uneven, the sides of the median 

 sulcus becoming prominently elevated and cariniform anteriorly, 

 the portion between the carinaeand the sides feebly, unevenly concave, 

 the entire surface with coarse shallow punctures bearing each a very 

 large yellowish scale (cf), or a narrower squamiform hair (9); 

 scutellum small, narrow and elongate, flat and finely, densely squamu- 

 lose; elytra evidently shorter than wide, nearly one-half longer than 

 the prothorax (cf ), or a third (9 ), about two-fifths wider, the sides 

 feebly arcuate, just visibly converging from base to the broadly 

 rounded apical angles, the humeri not in the least prominent, the 

 slight callus continued obliquely as a broad feeble ridge to the apex, 

 the surface within the ridge somewhat concave, finely, irregularly 

 striate and with moderate close-set shallow punctures. Male with 

 the pygidium very convex, large, twice as wide as long, closely 

 covered with large yellowish scales, the hind tarsi three-fourths 

 longer than the tibiae, the basal joint not as long as the following three. 

 Female with the pygidium shorter and less convex, about three times 

 as wide as long, the upper margin not evenly arcuate as in the male 

 but less arcuate, becoming slightly sinuate medially, the similar 

 very close-set shallow areolae having a mixture of large scales and 

 blacker scale-like hairs; hind tarsi thicker, shorter, two-fifths longer 

 than the tibiae, with the basal joint more expanded at tip and as long 

 as the next three combined. Propygidium with the same sculpture 

 and vestiture as the pygidium in each sex. Length (9 cf, 18 9) 

 5.5-6.6 mm.; width 3.0-3.5 mm. New York to North Carolina and 

 westward to Iowa. Abundant. [ V. seticollis Beauv.] 



squamiger Beauv. 



Female with the apex of the pygidium prolonged obliquely in a long, 

 straight, gradually tapering acuminate process, the upper side of 

 which is feebly canaliculate, the edges of the groove strongly, ir- 

 regularly serrate in the European hemiptents, but smooth in the 

 American species, so far as observed; body nearly similar to the pre- 

 ceding in general appearance. (Acanthurus Kirby) 2 



2 Size very small, the pronotal impression deep and well defined by 

 parallel carinae anteriorly; sides serrulate, more strongly in front. .3 



Size large, the anterior pronotal impression feeble; sides not serrulate. .4 



3 Form oblong-ventricose, rufo-piceous or in part blackish; head rather 

 more than half as wide as the prothorax, more or less sparsely and 

 unevenly squamulose, the large flat clypeus distinctly sinuate medi- 

 ally at apex, the sinus broader than the lobes; antennae very small;
