STAPHYLINID/E 157 



the sides feebly rounded posteriorly, at base very little wider, the suture 

 a third longer, than the prothorax; abdomen at base much narrower 

 than the elytra, the sides thence evidently converging and nearly straight 

 through the fifth tergite, which is fully one-half longer than the fourth, 

 the first three impressed transversely at base. Length 3.0 mm.; width 

 0.8 mm. British Columbia (Metlakatla), Keen. 



This species is wholly isolated and I know nothing else that in 

 the least recalls it; no sexual marks can be discerned in the single 

 type which has lost both hind legs. 



Sipalia Rey. 



The species of this genus have a facies suggestive of certain 

 Bolitocharids, to the company of which it was assigned by Rey, 

 who associated with it as subgenera certain groups named Pasilia 

 and Pisalia, which as it happens are true Bolitocharids. The 

 present writer also fell into the same error, applying the name 

 Sibiota (Tr. St. Louis, XVI, p. 350) to an assumed Bolitocharid 

 which proves, upon observation under better conditions, to be a 

 Myrmedoniid, a subgenus of Sipalia Rey, and allied to the circel- 

 laris group. With the type of Sibiota, named impressula Csy., is 

 to be associated the species recently described (Mem. Col., I, p. 

 167) under the name Sipalia fossata Csy. Sipalia lineatula Csy., 

 (1. c.) will form another group or subgenus, with which the following 

 species may be associated : 



Sipalia fontana n. sp. Moderately slender and convex, parallel, 

 somewhat shining, the abdomen polished; color pale testaceous, the 

 head piceous-black, the elytra feebly clouded and abdomen with a large 

 black subapical area, the legs pale; punctures of the pronotum fine and 

 close, asperulate, of the elytra notably large, less close and very strongly 

 asperate, of the abdomen fine, sparse and asperulate; on the head they 

 are coarse and very shallow, rather close but not asperate and not divided 

 along the median line at least posteriorly; pubescence rather short, pale 

 and coarse; head rather transverse, barely three-fourths as wide as the 

 prothorax, the eyes small, having (cf ) about 26 or 27 coarse facets, the 

 tempora slightly more laterally prominent and much longer than the 

 eyes, arcuate and gradually converging to the base, the carinae strong and 

 entire; antenna? rather short, gradually and moderately incrassate, pale, 

 feebly infumate except basally and at apex, the third joint slightly 

 shorter though similar to the second, which is evidently shorter than the 

 first, fourth nearly as long as wide, thence gradually more transverse, 

 the outer joints nearly twice as wide as long, the last ogival, rather longer 

 than the two preceding; prothorax three-fifths wider than long, parallel,
