314 MEMOIRS ON THE COLEOPTERA 



minute cinereous vestiture only moderately dense, not concealing 

 the punctures, which, on the elytra, are notably strong, deep, not 

 dense but very clearly denned, also with unusually pronounced 

 sexual differences in form, the female being larger and relatively 

 much broader than the male and with more transverse prothorax, 

 testaceous in color, the two anterior pronotal dark spots conspicuous, 

 the posterior faded and ill-defined; elytra with the feebly elevated 

 lines more densely cinereo-pubescent and distantly penicillate, the 

 lateral black area slightly invading the disk, the oblique fasciae 

 broken and serrulate, by reason of a rounded black spot at about 

 the middle of each and on the first discal line. Length (cf 9 ) 

 5.6-7.8 mm.; width 1.9-3.0 mm. New Jersey and Massachusetts

cinereus Lee. 



Body narrower, more elongate and relatively more convex, piceous in 

 color, the elytral pubescence longer, coarser and very dense, con- 

 cealing the punctures, dusky-cinereous in color; prothorax two-thirds 

 wider than long, the spots small and obsolescent, the sides feebly 

 oblique before, very strongly oblique behind, the spiniform tooth 

 near the base; elytra finely, rather sparsely punctate, the scutellum 

 and elytral bead, thence posteriorly to the middle, infuscate, the 

 lateral cloud not invading the disk, the very oblique fasciae narrow 

 and more even, though largely composed of the three elongate black 

 spots, one on each of the three raised lines or threads, the latter here 

 very feeble though slightly marked by denser vestiture, the black 

 penicillations very small and sparse. Length (9) 6.2 mm.; width 

 2.2 mm. Indiana, [lateral-is Hald.] alpha Say 



12 Prothorax more or less nearly as in the alpha group preceding, 

 strongly transverse, generally not much less than twice as wide as 

 long 13 



Prothorax much more elongate and relatively narrower, not much more 

 than one-half wider than long; body larger and more convex. ... 14 



13 Oblique fasciae of the elytra rectilinear, not broken submedially but 

 as usual not attaining the flanks; body stout, densely clothed with 

 short pale uniform ashy vestiture; color fusco-testaceous; prothorax 

 nearly twice as wide as long, swollen at the sides, the swelling with 

 an acute denticle at basal third, the three dark spots small, feebly 

 convex; elytra parallel, obliquely and feebly arcuate at the sides in 

 apical third, the narrow apices very obliquely and rectilinearly 

 truncate, the elevated lines feeble, remotely penicillate; lateral 

 dark cloud slightly invading the disk, the latter with a very feeble 

 clouded fascia behind and parallel to the narrow black fascia, which 

 is at apical third; femora moderately clavate, the posterior scarcely 

 at all less so. Length (9) 5-8 mm.; width 2.4 mm. District of 

 Columbia moderator n. sp. 



Oblique fasciae very indistinctly marked, broad but suffused, interrupted 

 and sometimes obsolete; body narrower and more depressed than 

 in the preceding, the vestiture yellowish-cinereous and not so con- 

 spicuous as usual in this group, the raised elytral lines obsolete except
