COLEOPTERA OF SOUTHWESTERN PENNSYLVANIA. 353 



Eumicrus n. sp. — This is a small sj^ecies, 1.2 mm. long, resembling a miniature 

 Cholerus zimmermnnni in appearance, and more or less also in sculpture, but 

 has the long posterior coxse of Eumicrus. A colony of twenty-two specimens 

 was found Dec. 26, 1894, in the black, accumulated, decayed material of a 

 partially hollow, though still living, oak that had been broken down by a 

 recent storm. 



Brachycepsis subpunctatus Lee. — Thirteen specimens, found at different 

 times among decaying leaves. 



Brachycepsis marise Lee— Taken more abundantly (thirty specimens) with 

 the last, also obtained from Cambria County. 



Brachycepsis n. sp. (teste Dr. Brendel) — Very scarce, also taken with the last. 

 The antennal club of this consists of three large joints. 



Brachycepsis cribrarius Lee. — Eight specimens collected with the sieve, and 

 two on Dec. 26, 1894, with the above-mentioned Eumicrus sp. 



[Scydmsenus fossig'er Lee. — Abundant under stones, etc., March to April.] 



Scydmsenus from capillosulus to minimus were all taken at various times with 

 the sieve, or found in dead wood, or under stones; none at any time in the 

 company of ants. No notes were made of the captures of the different spe- 

 cies. For the names I am indebted to the kindness of Dr. Brendel. 



Scydmsenus minimus Brend. — Found in very friable, rotten wood in April, 

 usually in small colonies. 



Scydmsenus sp. long. .95 mm.— Probably not described, of the form of ovitho rax 

 Brend. Yellowish red ; the second joint of antennae the largest, the seventh 

 larger than its neighbors, club 3-jointed ; frontal margin without impressed 

 lines. One specimen. 



Scydmsenus clavipes Say. — Black, slightly larger than Sc. clavatus. Head and 

 elytra very shining, and with but few scattered long hairs ; the head lacks 

 the usual basal tufts of coarse hair, whereas the thorax is densely, almost 

 completely, covered with long, yellowish brown, bristling hair, giving it a 

 striking, shaggy appearance. Four examples sifted in Cambria County. April. 



PSELAPHID^. 



Faronus tolulse Lee. — Very scarce. Altogether but six specimens have been 

 taken on the Chestnut Eidge, by sifting layers of old leaves during Winter. 



Rhexius insculptus Lee. — Taken but rarely in dead wood under bark, or under 

 stones, and more abundantly with the sweeping-net in a grassy wood in 

 Spring. 



Rhexius schmitti Brend. — A single specimen found under a stone on the Chest- 

 nut Eidge in May. 



Rhexius canaliculatus Lee— Occurs abundantly in moss on the Chestnut 

 Eidge, also in North Carolina in Autumn and Spring. 



Rhexidius trogasteroides Brend. — Six males and one female have been sifted 

 from deep layers of old leaves on the Chestnut Eidge during Winter. 



Trimium parvulum Lee. — A colony of twenty to thirty specimens were, on one 

 occasion, taken in a very rotten oak stump in April, and a single individual 

 last July also in rotten wood. 



[Trimium thoracicum Brend. — Eare, six examples found in very rotten wood, 

 April 20th.] 



Trimium sp. — A single specimen, undescribed, with very widely separated oc- 

 cipital fovefe.
