170 MEMOIRS ON THE COLEOPTERA 



pleura testaceous, the disk of the elytra with a large black cloud in 

 about posterior two-thirds, not extending to the sides, the sutural 

 interval pale and with a lateral nubilous pale dilatation at about the 

 centre; under surface black, the legs pale; head actually but not 

 relatively larger than in pictus, three-fifths as wide as the prothorax, 

 the eyes and antennae similar; prothorax larger, more transverse, 

 one-half wider than long, similar, except that the base is more 

 rounded and more continuous with the sides, also more distinctly 

 wider than the apex; elytra oblong-oval, broader, with more rounded 

 sides and still more obtuse apex, only about a fourth longer than 

 wide and a third wider than the prothorax, the striae finer, much less 

 impressed and everywhere impunctate, the intervals flat, just visibly 

 convex internally, the apical sinuses only barely indicated. Length 

 (cf 9 ) 6.2-7.2 mm.; width 2.8-3.2 mm. Rhode Island, Massa- 

 chusetts, Pennsylvania and District of Columbia, [cinctus Say]. 



parmatus Say 



A Similar to the preceding in every way, except that it is much smaller 

 in size, the prothorax and elytra both shorter, the former three- 

 fifths wider than long and the latter barely a fifth longer than 

 wide; legs a little shorter. Length (cf) 4.8-5.1 mm.; width 

 2.0-2.2 mm. Indiana iterans n. subsp. 



Body less stout and very much smaller, piceous, the pronotum paler 

 at the finely reflexed lateral margins and with a small nubilous pale 

 cloud on each elytron near the suture and just behind the middle; 

 head blackish, as wide as long, three-fifths as wide as the prothorax, 

 the eyes large, the antennae very slender, filiform, the joints beyond 

 the second nearly equal in length as in the preceding species; pro- 

 thorax large, parallel, one-half wider than long, the sides broadly 

 rounded, the base broadly arcuate, somewhat lobed between the 

 impressions, the angles very broadly rounded as usual; impressions 

 small, deep but broadly prolonged anteriorly for some distance in a 

 very broad and evanescent, indefinite impression; apex rather deeply 

 sinuate from side to side; elytra oblong-oval, fully a fourth longer 

 than wide, nearly one-half wider than the prothorax, the sides 

 broadly arcuate, gradually oblique and straighter apically; surface 

 not distinctly opalescent, finely striate, the striae impunctate, all 

 distinct, the scutellar long, forming an even continuation of the first 

 stria, the basal part of which is detached, the fovea small but evident; 

 intervals flat or nearly so, the third with the usual three punctures 

 near the third and second striae; legs slender and rather long, the 

 hind tarsi five-sixths as long as the tibiae. Length (cf) 4.8 mm.; 

 width 2.1 mm. Rhode Island (Boston Neck). The single type is 

 immature innuens n. sp. 



5 Body small in size, much less broad in form, piceous-black, the 

 elytra nubilously somewhat paler laterally and also transversely 

 near basal fourth; under surface blackish, the legs pale; head 

 rather longer than wide, three-fourths as wide as the prothorax, 

 the eyes large; antennae as in the preceding species; prothorax 

 ( 9 ) relatively very much smaller, nearly three-fifths wider than 

 long, parallel, with rounded sides, the base almost circularly
