304 FAMILY IX. — ARADID^E. 



and sixth ventrals subequal in length, elytra extending to genital lobes; 

 female with dorsal genital segment about one-half as long as broad, its 

 hind margin truncate at middle, elytra not quite reaching its base. 

 Length, 7—9.5 mm. (PI. II, fig. 32). 



Southern half of Indiana, frequent, Feb. 11 — Oct. 1; Lake 

 County only in the north. Dunedin and St. Petersburg, Fla., 

 Dec. 3— March 15 (W.S.B.). Southern Pines, N. Car., 

 April (Davis). In Indiana it hibernates beneath half 

 buried logs and in summer occurs beneath bark and on a whit- 

 ish semi-woody fungus on stumps. In Florida it has been found 

 only beneath the bark of dead water oak, Quercus nigra L., where 

 it is common during the winter in small colonies in company 

 with Neuroctenus simples (Uhl.). The known range of A. acutus 

 covers most of the United States, extending west from New 

 England to the Pacific and south and southwest to Florida and 

 Texas, but it has not as yet been recorded from Canada. It is 

 readily recognized by its long black clavate second joint of an- 

 tennae and the pale markings of abdomen and elytra. These 

 are formed mostly of whitish granules and vary much in size 

 and extent, sometimes covering most of the connexival seg- 

 ments.
