162 MEMOIRS ON THE COLEOPTERA 



elytra red, with a common sutural piceous vitta extending to the 

 second stria, and another submarginal and slightly abbreviated at 

 the ends; it is from New York. 



Tritoma nigripennis n. sp.- Body oblong-oval, obtuse behind, convex, 

 shining, ferruginous throughout above and beneath, but with the entire 

 elytra black, the coloration exactly as in affinis; head fully half as wide 

 as the prothorax, finely, evenly and sparsely punctate, the antennae and 

 eyes nearly as usual, the latter strongly convex; prothorax short, rather 

 more than twice as wide as long, the sides converging and nearly straight 

 from the base, more arcuate anteriorly, the lateral bead slightly thickened 

 at the moderately advanced apical angles, the apex broadly sinuate, the 

 bottom of the sinus slightly arcuate medially; basal lobe rather strong, 

 gradually formed, somewhat narrowly rounded; punctures fine but dis- 

 tinct, sparse, less so laterally; scutellum piceous-black, finely punctured, 

 smooth apically; elytra barely more than a third longer than wide, slightly 

 behind the base a little wider than the prothorax, the sides broadly ar- 

 cuate, only very moderately converging posteriorly, the combined apex 

 broadly obtuse; punctures moderate but deep, close-set in even series, 

 which are distinctly impressed, especially toward the sides, the intervals 

 with sparse and fine but very evident punctulation; epipleura wholly 

 black; under surface uniformly ferruginous, the sterna finely and sparsely, 

 the abdomen strongly and, toward the sides rather closely, punctured. 

 Length 3.8 mm.; width 2.15 mm. Florida (Lake Worth), Kinzel. 



Allied to affinis but more oblong and very much more obtuse at 

 apex, differing especially, however, in the strong and rather close-set 

 punctures of the abdomen. 



Tritoma Carolines n. sp. Oval, convex and rather shining, pale flavo- 

 testaceous throughout above and beneath, the elytra black, each with a 

 large triangular basal spot, of the same color as the anterior parts, ex- 

 tending from the humeral callus to the scutellum and occupying rather 

 more than basal fourth of the length; head half as wide as the prothorax, 

 the eyes moderate in size and prominence, the punctures fine but strong 

 and well separated; antennae pale, the club infuscate; prothorax not quite 

 twice as wide as the median length, the sides converging and very feebly 

 arcuate from base to apex, the latter broadly and feebly sinuate from side 

 to side, the angles rather obtuse and barely at all advanced; basal lobe 

 large and gradually formed, broadly rounded; punctures fine and sparse 

 throughout; base a little narrower than the elytral base; scutellum with 

 a few minute punctures; elytra less than one-half longer than wide, dis- 

 tinctly wider near basal fourth than at base, the sides there somewhat 

 prominently rounded, thence arcuate and rather converging posteriorly, 

 the apex moderately obtuse; punctures fine and not deep, close-set in 

 regular series that are not impressed, except feebly toward the sides, the 

 eighth at a considerable distance from the sides; intervals remotely and 

 extremely minutely punctulate; under surface sparsely and excessively 

 minutely punctulate throughout. Length 3.7 mm.; width 2.2 mm. 

 North Carolina (Southern Pines), Manee.
