330 MEMOIRS ON THE COLEOPTERA 



much narrower than the elytra, almost parallel, the sides feebly 

 prominent medially, the spicule strong, near basal fourth; surface 

 dull black, rather finely but very deeply and densely punctate; 

 elytra broadly cuneiform, three-fourths longer than wide, with very 

 widely exposed and slightly rounded humeri, within which the 

 surface is somewhat impressed, the sides just visibly sinuate for 

 a short distance behind the humeri, thence converging and feebly 

 arcuate, then gradually more strongly to the apical angle, which is 

 produced and spiculiform; surface uniform in sculpture and ves- 

 titure but flat medially and, except basally, sloping at the sides to 

 the lateral carina, which is very finely acute and subprominent; 

 punctures strong but not very coarse and notably close-set; flanks 

 more shining, strongly and closely punctate and picescent; femora 

 clavate, the posterior ( 9 ) more slender though rather distinctly 

 clavate distally. Length (9) 5-9 mm.; width 2.25 mm. Florida. 



femoralis Hald. 



15 Elongate, subparallel, dark testaceous, clothed throughout very 

 densely with conspicuously pale cinereous-white pubescence; head 

 well developed, indented; antennae testaceous, blackish apically, 

 the scape sometimes piceous, twice as long as the body (cf 1 ) or a 

 little less ( 9 ) ; prothorax subsimilar in the sexes, about three-fourths 

 wider than long, subparallel, the spicule rather strong, at basal fifth; 

 surface densely cinereous, the sculpture concealed, the four black 

 spots well developed; elytra three-fourths longer than wide, the 

 punctures strong and rather close when exposed but normally entirely 

 concealed by the vestiture, the spots of blackish tint small, occasion- 

 ally subobsolete, scattered, the posterior discal spot relatively very 

 small and sometimes wanting; lateral carina fine, rather prominent; 

 apical angles dentiform, somewhat blunt; flanks moderately punc- 

 tate, closely so, the cinereous vestiture distinct but less dense than 

 above; male with the hind legs rather long, approaching Anisopodus, 

 the fifth ventral equal in length to the preceding, broadly rounded, 

 with a feeble and moderately narrow apical sinuation. Length 

 (cf 9 ) 5.0-6.3 mm.; width 1.8-2.35 mm. California (Sta. Cruz 

 Mts.) californica Csy. 



Maculata Hald., is a very peculiar species, universally misidenti- 

 fied in collections; it is probably of very local distribution on the 

 eastern Appalachian slopes; nigrella Hald., is also a distinctly 

 characterized form, not of wide dispersal; in fact most of the 

 species seem to be narrowly circumscribed in habitat and, although 

 the Catskill example of cryptica described above is very similar to 

 the Indiana exponents, there is a certain quality in the vestiture 

 which may indicate a difference, racial or otherwise. The three 

 species variolata, cryptica and frigida, of the above table, are mu- 

 tually allied and, although easily differentiable on inspection, do 

 not have any marked structural differences that can be expressed
