AMARIN/E 245 



elytra more obtusely rounded behind and much more distinctly 

 wider than the prothorax, with feebly arcuate sides and deep mar- 

 ginal gutter, very opaque ( 9 ) or polished (cf ), the striae (9 ) finer, 

 feebly impressed and finely punctate, coarser (cf) and more abruptly 

 groove-like and also with more convex intervals; lateral series un- 

 interrupted; subapical sinus shallow; anterior tarsi (cf) broadly 

 dilated, the first three joints each with two oblique series of very 

 stout and erect, setiform fulvous squamules beneath. Length (cf 9 ) 

 9.0-12.0 mm.; width 4.3-5.3 mm. Lake Superior (Bayfield and 

 Marquette) and New York; also an unlabeled example from the 

 Levette collection. Moderately abundant. The male and female 

 both have two setigerous fovese at each side of the apex, the pairs 

 closer in the male; it is allied to the European patricia Duft., but is 

 apparently by no means the same species obesa Say 



Coloration generally rather more rufo-piceous in the female, where the 

 elytra are opaculate; they are black and with varnish-like polish 

 throughout in a male assumed to be of this species but without 

 locality label; head one-half as wide as the prothorax, of the usual 

 structure, the eyes well developed but not very convex; prothorax 

 one-half to three-fifths wider than long, with general form and struc- 

 ture as in obesa, but more transverse and with the side margins still 

 more broadly, strongly reflexed and usually more completely attain- 

 ing the base outside of the carina; elytra two-fifths longer than wide, 

 barely visibly wider than the prothorax, the striae coarse, groove- 

 like and at the same time impressed, being much coarser, deeper 

 and more strongly punctate than in the female of obesa. Length 

 (9) 11.7 mm.; width 5.6 mm. Northern Illinois (Highland Park). 



latissima n. sp. 



5 Form short, very stout, ventricose, convex; coloration and lustre as 

 in obesa, the elytra opaculate in the female; head half as wide as 

 the prothorax, the eyes more prominent than usual, the antennae 

 obscure ferruginous, not quite extending to the thoracic base; pro- 

 thorax slightly less than one-half wider than long, as in obesa, except 

 that the sides are more widely reflexed toward base, where the ob- 

 tuse carina is less oblique than usual, and, more especially, abbre- 

 viated well before the basal margin; foveae large, shallow, imper- 

 fectly separated; elytra barely two-fifths longer than wide, about a 

 fifth wider than the prothorax; parallel and arcuate at the sides, 

 striae rather strongly impressed, not fine and with thestrong punc- 

 tures crenating the convex intervals; sides of the metasternum, the 

 met-episterna and the abdomen latero-basally with numerous mod- 

 erate equal punctures. Length (9) 10.5 mm.; width 5.0 mm. 

 New York (Long Island) ventricosa n. sp. 



While all the above forms adhere closely to a common generic 

 facies, I feel quite certain that they differ specifically from each 

 other. The single male placed with the type of latissima was un- 

 labeled in the Levette collection and has the surface highly polished 

 as though glazed throughout above; it is not deep black and
