I have one specimen from New York in which the prothorax is very dis- 

 tinctly punctured, but it does not otherwise difter. 



2. A. nigripes Lee, Ann. Lye. Nat. Hist. (N. Y.), i, 171 ; pi. 11, f. 6 ; 

 Gyll., Sch. Cure, i, 199. 



9 . Front thighs unarmed. 



(j^. Front thighs strongly toothed. 



Atlantic States to Kansas ; abundant. The legs are usually black or 

 dark brown ; in one specimen from Texas (Belfrage), they are of the same 

 red color as the body. In other specimens the head prothorax and part of 

 the under surface are dark brown. 



3. A. bipustulatus Fabr., Mant. 229 ; Syst. El. ii, 418 ; Gyll. Sch. 

 Cure, i, 201 ; Harris, Ins. Inj. Veg. 58. 



Atlantic States, not rare. The front thighs are armed with a small acute 

 tooth in all the specimens I have seen. 



4. A. genalis, n. sp. 



Of the same form and size as A. bipustulatus, but with the apical angles 

 of the beak acute, and projecting laterally. The color is black, not blue, 

 the elytra are red with a large triangular scutellar spot, and a large apical 

 blotch black ; the abdomen is red. Length 3.2 mm's ; .125 inch. 



(^. Front thighs armed with a long slender tooth. 



$ . Front thighs unarmed. 



New Mexico. The species in our fauna resemble each other in form and 

 sculpture to such an extent, that I have not thought necessary to give a 

 more detailed description of this very distinct species. 



5. A. rhois Boh., Bull. Mosc. vi, 21 ; Gyll., Sch. Cure, i, 202 ; A. pubes- 

 cem Say, J. Ac. Nat. Sc. Phil, v, 252 ; ed. Lee. ii, 315. 



Lake Superior to Virginia. Not rare on hazel bushes. 

 Attelabus scutellaris Say does not belong to this fomily, and is the type 

 of the genus PiazorMmis Sch. 



Family lY. BYRSOPID^. 



Mentum moderate in size, trapezoidal, wider in front, concave in our 

 species ; gular peduncle very small ; ligula and palpi small. 



Maxillae exposed, small, palpi very short. 



Mandibles stout and short, pincer shaped, without apical scar. 



Antennae short, inserted in front of the eyes, sub-geniculate ; scape short, 

 funiculus 7-jointed, the last joint wider fornvng part of the club in Thece- 

 sternus, club annulated, oval, pointed, and covered with sensitive surface. 



Head strongly deflexed, beak short, stout, not emarginate at tip, separated 

 from the head beneath by a strong gular constriction, for the reception of 

 the antennae. Eyes transverse narrowed beneath.
