 Thorax broader than the elytra, sides strongly arcuate.

Color pitchy black, apex of elytra paler. 



Form convex, femoi'a and coxae piceous naiiiis. 



Form sub-depressed, legs testaceous Mcitiilii!^.

briiiineus. 



T. niaciilipciinis, Lee. — Piceo-testaceous, shining, convex. Head smooth, 

 black, shiuitij;. Antennae testaceous, as long as head and thorax. Thorax 

 testaceous, smooth, shining, nearly twice as wide as long, not wider than the 

 elytra, sides arcuate and gradually narrowed to apex, hind angles broadly 

 rounded. Scutellum piceous. Elytra conjointly wider than long and slightly 

 longer than the thorax, tips conjointly feebly emarginate, disc shining, very 

 sparsely and minutely punctulate, sparsely pubescent, color testaceous, a spot 

 near the side margin and one oblique, on the middle of each elytron black. 

 Abdomen piceous, hind margins of each segment paler, sparsely punctulate 

 and pubescent. Body beneath piceous, abdomen more distinctly punctured 

 than above. Legs testaceous, anterior coxae very slightly darker. Length 

 .14— .16 inch; 3.5— 4 mm. 



In form this species resembles chr/jsomc/imo;, Liun., but the thorax 

 is less broad. The ornamentation of the elytra resembles somewhat 

 that of Cilea silphoides. 



Appears to be very widely distributed, Michigan to Georgia, Middle 

 Statt s to Kansas. 



T. elegans, n. sp.— Bright rufo-testaceous, head, last two segments of 

 aJidomen, and scutellar spot black. Antennae slightly longer than tha head 

 and thorax ))ale testaceous. Thorax as in the preceding. Elytra rufo-testace- 

 ous, paler than the abdomen, a cii'cum scutellar spot piceous, surface distinctly 

 punctulate, sparsely pubescent. Abdomen bright rufo-testaceous, last two seg- 

 ments bl.ick, surface sparsely punctulate and pubescent. Body beneath rufo- 

 testaceous. abdomen more distinctly punctured than above. Legs pale testace- 

 ous. Length .14 inch; 3.5 mm. 



This species resembles jocoam m form. Differs remarkably from 



all our .species in its coloration and resembles in this respect obtusus,
