*2384 (7649). PENTHE OBLIQUATA Fab., Syst. Eleut., I. 1701. 102. 



Broadly oval, subdepressed. Velvety black, feebly shining; scutelluiu 

 covered with long, orange yellow hairs. Thorax more than twice as wide 1 

 as long, hind angles rectangular; sides nearly parallel on basal half, thence 

 rounded to apex, base bisinnate ; surface densely and linely granulate-punc- 

 tate and with a deep oblong impression each side near base. Elytra with 

 closely placed rows of deep, round punctures; intervals narrower than the 

 rows of punctures, densely granulate-punctate. Length 11.5-14 mm. 



Throughout the State ; common. April 12-December 5. Occurs 

 on woody fungi and beneath hark of decaying wood. 



(7650). PENTHE IMMETIA Fab.. Syst. Eleut.. I, 1701, 40. 

 Readily known from the preceding by having the scutellum black, not 

 orange yellow. The thorax is slightly shorter and wider, its hind angles 

 much more acute and surface densely and more or loss continently punc- 

 tate without granules. Length 10-14 mm. 



Throughout the State ; more common than obliquata. February 

 23-December 8. Both species are gregarious in winter, and hiber- 

 nate beneath partly buried logs, especially those of beech in open 

 upland woods.

This in turn is represented in the eastern United States by a 

 single brown species having the head prominent and horizontal; 

 maxillary palpi moderate in lengtb, but slightly dilated; antenna 1 

 long, slender and feebly serrate, the second joint one-third the 

 length of third, the latter slightly longer than fourth; tarsi filiform, 

 claws simple ; tibial spurs long.

Elongate, slender. Dark brown, rather densely clothed with ash-gray 

 pubescence; antenna?, tibia? and tarsi paler. Thorax one-half wider at base 

 than long, sides nearly straight, converging from base to apex; hind an-

 impression each side near base. Elytra with a sutural groove on apical
