STAPHYLINID.E. 69 



Atheta (Adota) gnypetoides n. sp. General form, coloration and sculpture 

 as in the two preceding but smaller, the micro-reticulation rather feebler 

 and the surface therefore less dull, the stiff dark cinereous vestiture similar; 

 head nearly as long as wide, the eyes at somewhat more than their own length 

 from the base, the tempora parallel, feebly arcuate, not more prominent; 

 antennae nearly similar; prothorax but little wider than long and only slightly 

 wider than the head, the sides rounded anteriorly, becoming convergent 

 and nearly straight posteriorly from a little before the middle, unimpressed ; 

 elytra very much wider and longer than the prothorax, parallel, as long as 

 wide; abdomen relatively not so narrow as in the two preceding, the parallel 

 sides feebly arcuate posteriorly, the subapical width nearly equaling that of 

 the elytra. Length 2.2 mm.; width 0.52 mm. California (Redondo), Fall. 



Evidently congeneric with the preceding far northern forms, but 

 to be readily distinguished by the narrower prothorax, less convex 

 eyes and form of the abdomen; the type is a female, but the male 

 characters probably do not materially differ. 



Rovalida n. subgen. 



This subgenus seems to represent the preceding on the Atlantic 

 coast and the Pachnida, of Europe, the body being of similar rather 

 depressed form and subopaque lustre and with conspicuous pubes- 

 cence, but differing in the very small antennae. The mesosternal 

 process extends to slightly behind the middle of the coxae, the apex 

 being gradually very finely aciculate and well separated by a deep 

 excavation from the somewhat acute apex of the large, angulate 

 metasternal projection. The first four joints of the hind tarsi are 

 not much elongated and are equal, the fifth only as long as the 

 two preceding; other generic characters can be inferred from the 

 following descriptions, the first being the type:* 



Atheta (Rovalida) cribraticeps n. sp. Rather slender, linear, subdepressed, 

 dark rufo-piceous, the head and subapical cloud on the abdomen black, 

 the legs and antennae throughout rather pale flavo-testaceous; lustre dull, 

 the abdomen shining, the punctures fine, asperulate, close, the vestiture 

 short but coarse, dark cinereous and distinct; head well developed, wider 

 than long, coarsely and closely punctate, very feebly impressed centrally, 

 the eyes rather small, prominent, at one-half more than their own length 

 from the base, the tempora laterally swollen, rounded and more prominent 

 than the eyes, the carinse fine, not quite entire; antennae very short, scarcely 

 extending to the base of the prothorax, gradually incrassate, the outer joints 

 strongly transverse, the last short, small, obtusely pointed, much shorter 



*I at first thought that this subgenus, or perhaps more properly, genus, might be 

 the same as Halobrecthina Bernh., but in that group the head has no infra-lateral 

 carinae.
