185 



Length, 0.45 to 0.5 inch. Massachusetts (Harris). 



All these are placed by Harris under the following division : 



Antennae 14-jointed. Eyes very prominent, with a projecting ridge 



between them, formed by a horizontal extension of the flat top of the head. 



Thorax (pronotum) prolonged beyond the extremity of the body. 



T. ciiciillnta, Scudd., Bost. Jour. Nat. Hist., VII, 475. 

 Syn., Tetrix ciicullata, Burm., Handb. Ent., II, 658. 



Vertex at the front border smaller than across the middle of the promi- 

 nent eyes. Testaceous-fuscous, granulose. Pronotum dilated in front, ad- 

 vanced upon the head to the eyes. 9 4 to 5.5 lines. • South Carolina (Bur- 

 meister). 



Differs from T. granulata, which it most resembles, in having the vertex 

 very narrow, slightly less than the diameter of the much-inflated eyes, the 

 front cut off square and slightly hollowed, not projecting outward so far as the 

 eyes. The pi'onotum is broader and more compact over the thorax, more 

 suddenly sloped off* "behind, and extending backward nearly twice the length 

 of the abdomen, the wings overreaching slightly. The punctures upon the 

 elytra are of the same size, but not so deep, as in T. granulata. 



Length of pronotum, 9 0.5 inch ; 3 0.4 inch. 



Massachusetts, Missouri (Scudder). 



T. femorata, Scudd., Trans. Am. Ent. Soc, II, 305. 



Vertex but little broader than one of the eyes, barely projecting in 

 advance of them; the front scarcely rounded. Pronotum reaching to the tip 

 of the abdomen, not including the ovipositor; median carina very prominent, 

 slightly arched ; surface arenose. Elytra small, well rounded, with shallow 

 punctures. Wings not longer than the elytra. Hind femora very broad and 

 stout. 



9 Length, 9.5 miUimeters ; pronotum, 8 millimeters; elytra, 1.6 milli- 

 meters ; hind femora, 5.2 millimeters. 



Maryland (Scudder). 



T. triaiagularis, Scudd., Bost. Jour. Nat. Hist., VII, 475. 



Allied to T. ornata, and agreeing with it in ornamentation, in the char- 

 acter of the vertex and prominence of the eyes, but differing in the length of
