64 Memoirs on the Coleoptera 



sinuate apex; surface with the transverse rugulee very fine, feeble, 

 irregularly somewhat close-set and scratch-like; anterior impression 

 fine, barely traceable, the posterior wholly wanting, but said to be 

 well marked in the LeConte type, the stria fine, feebly impressed; 

 fovese large, somewhat deeply, subevenly concave, not strongly 

 sculptured; margins rather narrowly but strongly reflexed, barely 

 more so toward base; elytra one-half longer than wide, not quite 

 twice as wide as the prothorax, rather depressed, gradually obtusely 

 rounded behind, the sinus distinct; striae fine, feebly impressed, 

 just visibly micro-punctulate; intervals not quite flat, the third 

 with five not large but broadly impressed foveae, the three or four 

 anterior at the third stria, the fifth more axial; anterior male tarsi 

 very moderately dilated, the first three joints diminishing uni- 

 formly and rather rapidly in length and very slightly in width. 

 Length (d^) 6.7 mm.; width 2.5 mm. Hudson Bay Region, — Leng. 



marginellus Lee. 

 Body with brighter green metallic lustre on the head and pronotum, the 

 latter however becoming more abruptly testaceous and non-metallic 

 about most of the contour, and especially so between the linear 

 fovese and the sides. Elytra, epipleura and legs pale brownish- 

 flavate; under surface nearly black; head slightly elongate, nearly 

 four-fifths as wide as the prothorax, with notably large and promi- 

 nent eyes; antennae slender, slightly more than half as long as the 

 body, fuscous, the first three joints paler, the third and fourth equal; 

 prothorax a fourth wider than long, widest before the middle, 

 though with broadly and moderately arcuate and rather finely 

 reflexed sides, which become almost straight basally, the angles 

 very obtuse and with their tips blunt; base as wide as the feebly 

 sinuate apex, obliquely rounded at the sides; surface smooth, the 

 anterior impression feeble, angulate, the posterior obsolete, the 

 stria very fine; foveae smooth, narrowly and deeply linear, not 

 anteriorly prolonged; elytra oblong-oval, rather convex, less than 

 one-half longer than wide, abmit twice as wide as the prothorax, 

 the sides rapidly rounding at base; apex gradually rounding in 

 nearly posterior half, the sinus very short and feeble; striae fine, the 

 micro-punctulation traceable laterally; intervals flat, the third 

 with five punctures, which are relatively much stronger than in 

 tritus or fractus, the three anterior adjoining the third, the other 

 two the second, stria; anterior male tarsi with very moderately 

 dilated and unusually elongate joints, rather wider and much longer 

 than in the male of tritus. Length (cf ) 6.6 mm.; width 2.35 mm. 



Massachusetts (Chicopee) anchomenoides Rand. 



Body without distinct metallic lustre at any point 14 



14— Prothorax small, as long as wide and but little wider than the head; 

 elytral punctures five, very minute. Body and legs pale ferruginous 

 throughout, the head piceous-black; surface smooth, feebly sculp- 

 tured and shining in both sexes; head but slightly elongate, with 

 large and prominent eyes and short, unevenly lineate anterior 

 impressions; palpi piceous, the last joint slightly longer than the 

 third; antennae very slender, fusco-testaceous, clearer basally.
