39Q MEMOIRS ON THE COLEOPTERA 



but a trifle narrower; antennae long, very slender, fusco-testaceous, 

 paler basally; prothorax only just visibly wider than long, widest 

 slightly before the middle, the sides less rounded than in the pre- 

 ceding, gradually less arcuate basally, where the angle is distinctly 

 more than right and not at all rounded, but with its apex not at all 

 prominent; apex as in inquietus, except that the angles are blunter 

 and the incised line finer, feebler and subinterrupted at the middle, 

 the surface otherwise as in the preceding, except that the fine median 

 stria is more impressed, the ruguliform lines obsolete and the fovese 

 less elongate; elytra three-fourths longer than wide, a third wider 

 than the prothorax, gradually rounded behind, the sinus shallow; 

 striae fine, feebly impressed suturally, the punctures extremely mi- 

 nute, the seventh distinct to the base but feebler than the others; 

 intervals nearly flat. Length (cf 1 ) 8.7 mm.; width 2.9 mm. Dis- 

 trict of Columbia, Ulke velocipes n. sp. 



20 Lfcgs pale ferruginous throughout; hind thoracic angles obtuse and 

 rounded at tip. Black, the elytra feebly iridescent; head two-thirds 

 as wide as the prothorax, not elongate, the eyes very prominent; 

 labrum and mandibles rufo-castaneous; antennae fuscous, paler bas- 

 ally; prothorax parallel, a fourth wider than long, the sides evenly, 

 moderately rounded and finely reflexed from apex to base; apex 

 feebly sinuate, with obtuse angles, not distinctly narrower than the 

 base, which is rufescent medially, finely margined laterally; apical 

 incised line distinct and entire; impressions feeble though visible, 

 the stria very fine; subbasal punctures obsolescent; foveae narrow, 

 deep, far from attaining the base; elytra one-half longer than wide, 

 barely a third wider than the prothorax, gradually rounding behind, 

 more rapidly at apex; sides more rounding basally; striae not very 

 fine, moderately impressed, distinctly though not coarsely, crenu- 

 lately punctate, the seventh obsolete basally; intervals moderately 

 convex; subapical sinus very shallow. Length (9 ) 6.5 mm.; width 

 2.35 mm. Indiana vulneratus n. sp. 



Legs dark, the femora black; hind thoracic angles slightly more than right, 

 but not rounded and more or less indistinctly, minutely and bluntly 

 subprominent 21 



21 Body oblong-suboval, rather convex, polished, black, the tarsi rufo- 

 piceous; elytra with moderate iridescence; head nearly two-thirds as 

 wide as the prothorax, with rather long neck and prominent eyes, 

 scarcely elongate; mandibles and labrum very dark; palpi pale; 

 antennae brownish-testaceous, a little clearer basally; prothorax a 

 fourth to third wider than long, parallel, with evenly and distinctly 

 arcuate and finely reflexed sides, the apex moderately sinuate, with 

 bluntly rounded angles and only slightly narrower than the base, the 

 incised line fine and feeble though entire and unusually close to the 

 apical edge; medio-subbasal punctures few, clustered toward the 

 foveae, which are moderate, rather deeply impressed; elytra rather 

 more than one-half longer than wide, scarcely a third wider than 

 the prothorax; parallel, rapidly rounding behind, the nearly straight 

 sides more rounding basally, the sinus feeble though evident; striae
