{Aphaenogastcf fiilva ) but usually 

 take it at large. 



Sropaeus bi-evipeitnis Ca.ity (in litt.). 

 This is the species recorded in the pre. 

 vious paper, without a name. It occurs 

 with ApJiaenogaster fulva. 



Oxvte/iis placusinus Lee. and O. 

 suspectjis Casey were taken with For- 

 mica subsericca. They probably make 

 galleries of their own in the ant-hill rather 



than dwell in the run ways of' the ants. 

 Atomaria tnesotnela Hbst.. ''or one 

 of the other 4-maculate species" (Bren- 

 del). This occurs at Iowa City with 

 an Aphaenogaster, the identit\- oi 

 which cannot be deteiniined with the 

 limited material in hand. Several 

 specimens were taken from one nest. 

 This is probably not the customary 

 habit of this species. 



TWO CAVE BEETLES NOT BEFORE RECORDED. 



BY H. GARMAN, LEXINGTO-N. KV. 



Two small beetles have proved so 

 constantly present in small caves in 

 the vicinity of Lexington that it seems 

 worth while to place them on record 

 as cave insects. Both have pretty well 

 developed eyes and ma}' therefore live 

 at times in ordinary situations, but 

 thev are perfectly at home in the deep- 

 est parts of caves and are at times very 

 abundant there. In all my collecting 

 in ordinar\ situations I have not seen 

 either species out-of-doors, and am 

 disposed to consider them true cave 

 dwellers. 



Clioleva alsiosa, Horn. This is a 

 small black beetle (one of the Silphi- 

 dae) about 4.5 mm. in length, described 

 in 1SS5 by Dr. Horn from the Yukon 

 River, Alaska. Is it possible that the 

 low temperatui'e prevailing in the caves 

 has enabled this insect to persist here 

 since glacial times.' I have several 

 hundred specimens, male and female, 

 all taken in caves beyond the penetra- 

 tion of li<rht. 



Calodcra cavicola, n. s. A small, 

 reddish brown insect with very short 

 wing covers and a slender elongated 

 body. Head generally darker than 

 the body, sometimes nearly black in 

 alcoholic specimens. The middle ot 

 the abdominal somites also darker than 

 elsewhere giving this division of the 

 bod}' an annulated appearance. Speci- 

 mens taken from the caves and kept 

 alive seem to me to become gradually 

 darker in general coloi . It is one of 

 the Staphilinidae. 



Length 4.5 — 6.0 mm. Greatest width 

 about i.o mm. OutUne of head, seen from 

 above, nearly circular, truncate behind, its 

 length contained I5 times in width, pube- 

 scent and obsoletely punctate above. An- 

 tennae when drawn back reaching nearly to 

 posterior edge of prothorax, gradually 

 enlarging from the base, finely pubescent, 

 and with a ring of rather strong hairs on 

 most of the segments. First to third seg- 

 ment cylindrical, the basal largest and long- 

 est of the three, the second and third nearly 

 equal; fourth segment shortest, contracted
