Abundant from New York and Massachusetts to Michigan. 

 Easily known by its black polished integuments and smaller size 

 from hrunneus, the only other species inhabiting the same districts. 



G. faiiveli n. sp. — Stout, feebly convex, polished, dark and uniform 

 piceo-castaneous throughout ; pubescence short and very sparse. Head finely 

 and sparsely punctate, three-fourths as wide as the prothorax ; eyes large and 

 prominent, the tempora not one-half as long, rapidly convergent and feebly 

 arcuate ; vertex deeply impressed in the middle and with two short deep 

 divergent grooves ; epistoma impunctate, deeply, arcuately impressed, the de- 

 pression connected with the vertical impression by a feeble channel ; antennae 

 filiform but rather stout, nearly three-fifths as long as the body, the basal 

 joint stout, twice as long as wide, second shorter than the fourth, third very 

 much longer, obconical, three times as long as wide, eleventh one-half longer 

 than the tenth. Prothorax one-half wider than long, the sides strongly, evenly 

 rounded, rapidly constricted toward base, becoming parallel in basal fifth or 

 sixth ; base truncate, one-third wider than the apex ; disk Avidest before the 

 middle, deeply, rather coarsely and closely punctate, deeply impressed along 

 the median line except near the apex, with a deep transverse pit before the 

 scutellum. Elytra scarcely as long as wide, as long as the head and prothorax, 

 near the apex two-fifths wider than the latter ; sides straight, strongly diver- 

 gent ; humeri widely exposed ; humeral width scarcely four-fifths of the sub- 

 apical ; punctures coarse, deep and not dense. Abdomen finely but not very 

 densely punctate ; border moderate. Legs and coxse pale rufo- ferruginous ; 

 under surface blackish-piceous. Length 5.8 mm. ; width 2.0 mm. 



Oregon (The Dalles). 



Allied to strictus but amply distinct in its broader form, much 

 more divergent sides of the -elytra, longer and stouter antennae, 

 and the sexual differences in the anterior legs, which are very 

 marked. A single male.

 Not. Ent., 7, p. 89 ; plagiatus Fvl. nee Fab.: Rev. d'Ent., 1889, p. 125. 



The specimens of ovipennis which I have examined can be distin- 

 guished very readily 1 think from plagiatus or nigrita by their 

 broader form, much sparser punctures which are coarser on the 

 elytra, the latter being much more abbreviated, and by the broader 

 abdominal border. I have seen no North American examples 

 which could be referred very satisfactorily to plagiatus. 



G. nuljilatus n. sp. — Polished black with a feeble piceous tinge, the 

 apex and lateral margins of the abdomen slightly paler ; legs, mouth parts
