ninth and tenth large, triangular; eleventh somewhat longer, oval. 

 Last joint of palpi a little elongate, gradually dilated and obliquely 

 truncate. Prothorax subcorneal, base subequal in width to the 

 elytra, disk evenly convex. Elytra with narrow deeply impressed 

 finely punctate striae. Prosternum not visible, except on dissection, 

 short, declivous ; front coxa? contiguous, their apices expanded into 

 a transversely elongate horizontal surface against which the mandi- 

 bles abut in repose. Mesosternum with a posterior compressed and 

 elevated process, its free edge horizontal, on a level with the meta- 

 sternum and extending from between the middle coxae to the ante- 

 rior coxae, the apical plates of which are on the same level. Middle 

 coxae rather narrowly separated, the legs received in deep excava- 

 tions of the mesothorax and metathorax. Metasternum deeply 

 channeled, declivous at sides in front, narrowly truncate at middle. 

 Hind coxal plates very narrow and parallel. Ventral segments not 

 very unequal, sutures nearly straight; first segment excavated for 

 the reception of the hind legs, and finely longitudinally bicarinate 

 at middle. Epipleurae foveate for the hind knees. Legs slender, 

 tarsi short, the first joint a little elongate. 



1. T. profunda, Lee. — Elongate-oval, piceous, antennae pale, legs and abdo- 

 men usually rufous; above with fine, moderately long, intermixed prostrate and 

 erect grayish pubesceuce. Head sparsely not coarsely punctate. Prothorax 

 strongly narrowed from base to apex, sides straight, finely margined, hind 

 angles obtuse; surface densely coarsely punctate, except toward the middle at 

 base. Elytra finely striate, strife finely punctate, the intervals about three times 

 as wide as the stria} and scarcely punctate. Beneath coarsely punctate, the 

 metasternum closely, the abdomen more sparsely so. Length 2-2.5 mm. 



A widely diffused species, but apparently nowhere common. The 

 following localities are represented in the material studied : Penn- 

 sylvania, Maryland, West Virginia, Michigan (Marquette and 

 Eagle Harbor), Oregon, California. 



The single specimen from California is the type of striatopunctata. 

 A careful comparison of this with the types of profunda from 

 Pennsylvania and Lake Superior and with Oregon specimens con- 

 vinces me that the differences mentioned by LeConte are only indi- 

 vidual and not greater than may be observed in Eastern specimens. 

 A single specimen from Texas in my own collection is perhaps dis- 

 tinct by its coarser elytral striae and more closely coarsely punctate 

 abdomen. I am unwilling to give it a name without seeing addi- 

 tional specimens.
