24 ENTOMOLOGICAL SOCIETY 



c Caves of the Alleghany Mountain District. 



Anophthalmus pusio Horn. Erhart's cave, Montgomery Co., Va. ; Luray 

 cave, Luray Co., Va. ; X cave, Carter Co., northeastern Kentucky. 



d Alabaster cave. El Dorado Co., CaL 



Anillus explanatus Horn. This species will no doubt be found also 

 under large stones or deep layers of old leaves outside of the cave. 



II. NON-CAVKRNICOLOUS SPECIES. 



Anillus debilis Lee. Found under stones at San Jose, Cal. (LeConte) ; 

 under old leaves at San Antonio, Texas (Schwarz). The only speci 

 men from the latter locality is in the LeConte collection at Cam 

 bridge. 



Anillus fortis Horn. Mountains of eastern Tennessee ; Mountain Lake, 

 Montgomery Co., Va. (Ulke) ; Penuington Gap, Cumberland Moun 

 tains, Va., under old leaves (Hubbard) ; Washington, D. C., under 

 deeply interred stones (Ulke). 



Anillus Dohrni Ehlers. Described from Florida without more precise 

 indication of locality. It has, to my knowledge, never been taken 

 by any American entomologist, and I cannot suppress some doubt 

 regarding the correctness of the locality. 



Platvpsyllus castoris Ritz. The well-known parasite of the beaver. 

 Specimens are known from Alaska, Canada, Nebraska, southwestern 

 Texas and southern France. 



Leptinus testaceus Mull. Parasitic on wood-mice and other small 

 rodents; known from Iowa, Pennsylvania, District of Columbia and 

 northern and central Europe. 



Leptinillus validus Horn. Parasitic on the beaver. Originally described 

 from the Hudson Bay region, it has subsequently been found on 

 beaver skins from Alaska. The species has feebly developed eye- 

 spots. 



Pinodytes cryptophagoides Maunh. Originally described from Sitka, 

 Alaska (found under a stone), it has subsequently been found in 

 large numbers in northern and southern California, in the mountains 

 of Virginia (Mountain .Lake, Ulke) and Maryland (Deer Park, 

 Schwarz), and at Washington, D. C. (Ulke, Schwarz). The speci 

 mens found by myself occurred under deep layers of decayed leaves. 



Pinodytes n. sp. A large and as yet undescribed species found by Dr. 

 Hamilton, near Pittsburg, Pa. 



Scydmtenida. An undescribed species of this family, and forming a new 

 genus, has been found by Mr. Ulke at Mountain Lake, Montgomery 

 Co., Va., in the ground under decaying leaves. The eyes are rudi 

 mentary.
