Casey — Observations on the Staphylinidae. 245 



lose, the fine carina not quite entire ; elytra transverse, of the usual 

 form with very widely exposed oblique humeri, the outer sides scarcely 

 as long as the prothorax, the punctulation fine and sparse, the post- 

 scutellar impression broad and deep; abdomen much narrower than 

 the elytra, parallel with arcuate sides, very sparsely, extremely minutely 

 and almost obsoletely punctulate, the impressions subequal, narrow, 

 rather deep, polished and impunctate, the basal with a few very obso- 

 lete and widely spaced punctures visible only under high power; legs 

 very slender, the basal jnint of the hind tarsi not quite as long as the 

 remainder. Length 2.6 mm.; with 0.62 mm. Iowa. 



biliiubata n. sp. 



The above identification of cingulata Lee, satisfies all the 

 published characters except sculpture of the abdomen and size 

 of the body. The rather close-set punctulation of the abdomen 

 is sufficiently evident, though very fine, but LeConte describes 

 the surface as smooth. The size is given as 3-3.5 mm. in 

 length, which, it seems to me, must be an error, as the 

 species of that size in the present genus are confined to the 

 Sonoran fauna, all the numerous eastern examples in my 

 cabinet being much smaller and frailer insects. It is prob- 

 able that the author described cingulata from a miscellaneous 

 collection of specimens, including cingulata ^to^qy and other 

 species, as well perhaps as some of the much larger representa- 

 tives of the genus Chitalia, and inadvertently measured some 

 of the larger specimens, making the observation concerning the 

 smooth abdomen from bilimbata, or some allied species, where 

 the abdomen is really almost smooth. It would be well, 

 therefore, to consider the species above selected as the true 

 cingulata, as it has the scutellar carina frequently entire and 

 therefore liable to be observed with the optical means of re- 

 search then in vogue and because all the other characters fully 

 satisfy the original description. 



Falagria Steph. 



This genus is distinguishable at once from any. other of the 

 subtribe by the acutely bicarinate scutellum. The body is 

 smaller in size than in either of the preceding genera, convex, 

 generally black or dark in color, with the characters as stated 

 in the table, the legs being rather short and stouter than 

 usual in dissecta and allied species, with the basal joint of the
