THE SHORT-WINGED SCAVENGER BEETLES. 367 



crawl into the deepest recesses of caves each day and emerge again 

 at night. So far hicifin/a has only been found in eaves, and. like 

 (Jiirdius spcla-us Horn, lias probably inhabited them too short a 

 I line to entirely lose the eyes. 



Subfamily II. STAPHYLININAE. 



Rather large or medium-sized black or brown species having the 

 antennas 11-jointed, situated at the front margin of the front; 

 spiracles of the thorax visible; front coxa; large and conical; tro- 

 chanters of hind legs prominent ; abdomen strongly margined. The 

 principal literature treating of the North American species of the 

 subfamily is as follows: 



Horn. "Synopsis of the Quediini of the United States," in. 



Trans. Amer. Ent. Soc.. VII, 1878, 149-167. 

 fforn. "Synopsis of the species of Staphylinus and the more 

 closely allied Genera inhabiting the United States," in 

 Trans. Amer. Ent. Soc., VII, 1878, 185-200. 

 LcConte. -"Short studies of North American Coleoptera," in 

 Trans. Amer. Ent. Soc., VIII, 1880, 168-174. Tabulates the 

 genera Leptaciuus, Xantholiniis and Leptolinus. 

 Jlorn. "Synopsis of the Philonthi of Boreal America," in 



Trans. Amer. Ent. Soc., XI, 1884, 177-244. 

 Casey. See above under Aleocharina\ 



Three tribes comprise the subfamily, all of which are repre- 

 sented in the State. 



KEY TO TRIBES OF STAPHYLININAE. 



(i. Side margins of the thorax simple. Tribe I. QUEDIINI, i>. 3<>7. 



<m. Side margins of the thorax double. 

 h. Antennae widely separated at base. 



Tribe II. STAPHYLININI, p. .">7.">. 



l>h. Antenna? rather close together at base: elytra often reddish, and in 

 most species overlapping along the suture. 



Tribe III. XANTHOLININI, p. 394. 



Tribe I. QUEDIINI. 



The members of this tribe have the antenna 1 inserted at the front 

 point of the side margin of the front: head usually with a distinct 

 suture beneath the eyes; thorax smooth and glabrous with but few 

 dorsal punctures, its side margin single and acute; tarsi in our spe- 

 cies 5-jointed. Three of the four recogni/ed genera are repre- 

 sented in the State.
