«584 TRANSACTIONS OF THE 



to produce an acute, but small, common emargination ; tergum 

 less than half the length of the elytra, blackish-brassy, somewhat 

 hairy ; feet yellow, pale ; tibiae with obvious, but not very promi- 

 nent spines. 



Length nearly one-twelfth of an inch. 



This is very broad in proportion to its length, iu consequence 

 of the great contraction of the abdomen in drying. It resembles 

 Jocosus N., but is wider in proportion to its length, without taking 

 into consideration the extraordinary brevity of the abdomen. [468] 



7. T. FABER — Thorax and elytra yellowish ; near the scutcl 

 depres.sed ; last joint of the palpi very short. 



Inhabits Indiana. 



Body somewhat depressed; head blackish-piceous, polished ; 

 antennae yellowi.sh towards the base ; palpi, penultimate joint 

 rather dilated ; ultimate joint very short, conic, hardly one- 

 fourth as long as the preceding; thorax honey-yellow, glabrous; 

 scutel small, dusky ; elytra paler than the thorax, slightly hairy ; 

 suture and base near the scutel a little dusky ; region of the 

 scutel somewhat indented ; tergum wider and more depressed 

 than in most species, paler towards the tip; beneath reddish- 

 brown ; feet yellowish ; tibiae a little spinous. 



Length about one-twelfth of an inch. 



The abdomen is more depressed than usual in this genus, and 

 the terminal joint of the maxillary palpi is much shorter than in 

 our other species. 



3Iuch reform seems requisite in this and the preceding genera. 



[According to Erichson this is the European T. faher. —

8. T. FIMBRIATUS Grav. — Varies in being more or lesss tinged 

 with ferruginous. The head and thorax are sometimes entirely 

 dull ferruginous. It is the loleti of Melsh. Catal., but it was after- 

 wards first described by Gravenhorst under the name which I 

 have of course adopted.
