AMARIN.E 37 



deep; antennae slender, only feebly compressed, extending nearly to 

 the thoracic base, piceous, the three basal joints and some of the 

 fourth bright testaceous; prothorax not quite one-half wider than 

 long, the sides feebly arcuate and subparallel, gradually more round- 

 ing and converging anteriorly: apex two-thirds as wide as the base, 

 with prominent though bluntly pointed angles, deeply sinuate; base 

 only very feebly sinuate laterally, the angles right and but slightly 

 blunt, the puncture a little nearer base than side; impressions evi- 

 dent though feeble; foveae just traceable, the short incised dash of 

 the inner distinct; elytra about as wide as the prothorax, nearly 

 three-fifths longer than wide, the sides very gradually rounding 

 posteriorly; lateral series well spaced but not interrupted medially; 

 striae fine, impunctate, coarser behind, the seventh distinct, the scu- 

 tellar oblique, joining the second well behind the base and the first 

 near basal sixth; intervals perfectly flat; tarsi long and slender. 

 Length (cf) 8.0 mm.; width 3.35 mm. Colorado (Akron), Shantz. 



turbata n. sp. 



Body more narrowly elongate-suboval, moderately convex, very bright 

 golden-aeneous above; under surface piceous, testaceous along the 

 middle; legs black, the tibiae rufous; head not quite half as wide as 

 the prothorax; eyes less convex than in the preceding or any other 

 species of our fauna, almost flattened, the superciliary punctures 

 subequal; strioles linear, feebly oblique; antennae very slender, only 

 slightly compressed, extending to the thoracic base, black, the three 

 basal joints and base of the fourth bright testaceous; prothorax 

 two-fifths wider than long, the sides subparallel, gradually strongly 

 rounding and converging before the middle; apex two-thirds as 

 wide as the base, deeply sinuate, with very prominent and only 

 slightly blunt angles; base rather rapidly posteriorly oblique toward 

 the sides, the angles right, scarcely at all blunt, the puncture about 

 equidistant from base and side; impressions obsolete, the stria very 

 fine but somewhat impressed; foveae completely obsolete, except 

 the short incised discal dash of the inner; elytra one-half longer than 

 wide, about equal in width to the prothorax, the sides very gradu- 

 ally rounding behind the middle, the subapical sinus small but dis- 

 tinct as usual; striae impunctate, rather strong and groove-like sutu- 

 rally, not coarser on the declivity, the seventh very fine and almost 

 obliterated, the scutellar long, feebly oblique and somewhat disin- 

 tegrated; intervals almost flat; sides of the metasternum and the met- 

 episterna with almost imperceptible punctulation. Length (cf 1 ) 

 7.0 mm.; width 2.8 mm. Connecticut (New London). A single 

 example taken by the writer devincta n. sp. 



26 Prothorax longer, not over one-half wider than long. Body elongate- 

 suboval, convex, polished, feebly bronzed; under surface black, shin- 

 ing; tibiae and tarsi rufous, the femora piceous; head well developed, 

 with very prominent eyes, more than half as wide as the prothorax, 

 the strioles short and fine; antennae missing in the type; prothorax 

 with the sides barely arcuate and just visibly converging, gradually 

 more converging in about anterior half; apex nearly three-fourths 

 as wide as the base, moderately sinuate, with rounded angles; basal
