44 PROCEEDINGS OP THE ACADEMY OF 



from Pentariaby the antenna, which are long and slender, very slightly thick- 

 ened externally, by the form of the mesosternum, as well as by the sexual 

 characters. 



Scutellum rounded triangular, last dorsal segment not prolonged, sixth 

 ventral visible ; hind tibiae slender, without ridges ; fourth joint of anterior 

 and middle tarsi emarginate, not smaller than the third ; claws dilated at base. 

 Hind coxae small. Mesosternum compressed, much elevated. Eyes coarsely 

 granulated, with a small emargination ; antennae long and slender, slightly 

 thickened externally, not serrate ; third and fourth joints each equal to the first 

 and second together, fifth and sixth a little shorter. Palpi ? 



In the male the fifth ventral segment is broadly emarginate, and from the 

 tip of the abdomen proceed two long triangular appendages, truncate at the 

 apex. The sculpture is of fine transverse lines. 



Yellow ; scutellar cloud and two posterior bands of elytra black, venter 

 fuscous, -12. Texas. 1. lae tula Lee. 



Pentakia Muls. 



Scutellum rounded triangular ; last dorsal segment of abdomen not pro- 

 longed ; sixth ventral segment visible ; hind tibiae without ridges, more slen- 

 der than in Anaspis ; third joint of anterior and middle tarsi not lobed, fourth 

 equal to the third, and emarginate ; claws dilated at base. Hind coxae smaller 

 than in Anaspis. Eyes coarsely granulated with a small emargination ; an- 

 tennae with the joints 4 6 short, 7 11 thickened, not serrate ; last joint of 

 maxillary palpi triangular, acute at tip. 



Notwithstanding the visible sixth ventral segment, the present genus is so 

 closely allied to Anaspis that it would be unnatural to place it anywhere but 

 in this family. The reduction in size of the hind coxae and the slender hind 

 tibiae indicate a relationship with Scraptia,. 



The species are small, narrow, finely pubescent insects, living upon flowers ; 

 the sculpture consists of very fine, transverse lines as in Anaspis. 



I have not discovered any external sexual characters. 



Body fuscous ; head, thorax, feet and base of antennae testaceous ; elytra 

 black, with a large spot before the middle, extending nearly to the suture, 

 and a broad band near the tip, yellow, *14. Middle States. Anaspis trifas-

Anaspis Latr. 



Scutellum rounded triangular, last dorsal segment not prolonged ; sixth 

 ventral not visible ; hind tibiae slightly thickened, without ridges ; fourth 

 joint of anterior and middle tarsi very small, received upon the third joint, 

 which is slightly lobed ; claws dilated at base. Hind coxae flat, moderate in 

 size. Mesosternum not compressed, finely carinate. Eyes coarsely granulated, 

 with a miall emargination ; antennae slightly thickened externally, not ser- 

 rate ; last joint of maxillary palpi rounded internally, pointed at tip. 



In the male two long, slender appendages are seen proceeding from between 

 the fourth and fifth ventral segments ; the fourth and fifth, and sometimes the 

 others, are longitudinally excavated. 



The genus Anthobates Lee. (Agassiz's Lake Superior, 231) was established 

 on false observations ; the type of it, Anaspis trifasciata Mels. cannot 

 be placed in the present genus, but must be referred to Pentaria Muls.. 

 the generic name under which the characters were first properly exposed. 



Body entirely black ; transverse striae exceedingly fine : 

 Thorax twice as wide as long ; base of antennae, palpi and front legs tes-
