1 68 MEMOIRS ON THE COLEOPTERA 



metrically though feebly inflated; lateral margins of the elytra more 

 distinctly serrate basally 2 



2 Mandibles broad, their outer margin strongly angulate; elytra not 

 explanate at the sides. [Type A. ccecns Duv.] Europe. 



*Anillus Duval 



Mandibles long, thin and nearly straight, their outer margin feebly and 

 evenly arcuate; elytra explanate at the sides. [Type A. explanatus 

 Horn]. Pacific coast of North America Anillaspis n. subgen. 



The typical species of the first of these subgenera may be de- 

 scribed as follows : 



Anillinus carolinae n. sp. Narrow, elongate-suboval, strongly convex, 

 shining, pale testaceous throughout; head three-fourths as wide as the 

 prothorax, polished, as long as wide, the impressions short and anterior; 

 antennae about as long as the head and prothorax, the latter not quite 

 a third wider than long, widest at anterior third, the sides rounded, 

 straighter and feebly crenulate basally; apex sinuato-truncate, barely 

 visibly wider than the base; subbasal impression deep, broadly angulate; 

 median line distinctly impressed, obsolete at apex; elytra nearly three- 

 fifths longer than wide, a third wider than the prothorax, elongate-oval, 

 very coarsely reticulate, the first stria distinct, the second feeble and dis- 

 integrated; sides with a medially interrupted series of widely separated 

 ocellate fovese. Length 1.6 mm.; width 0.48 mm. North Carolina 

 (Black Mts.), Wm. Beutenmiiller. Four specimens. 



It is possible that/07^5 Horn, from almost this identical locality, 

 may be allied rather closely to Carolina, but the base and apex of 

 the prothorax in the latter are subequal in width as in dohrni 

 Ehlers, from Florida. It is difficult, besides, to understand how 

 any such name as fortis could be applied to the very minute Caro- 

 lina. The head in fortis is said to be alutaceous and to have a 

 longitudinal impression at each side; the length is given as 2 mm. 

 My single specimen of explanatus Horn, was taken in Placer Co., 

 California. 



Lymneops n. gen. 



This singular genus combines some of the characters of the typi- 

 cal Bembidiids and the Tachys group following, and especially in 

 the absence of the scutellar stria, so uniformly present in all the 

 preceding genera, but wanting in Tachys and all related groups. 

 The outer maxillary lobe is of peculiar structure, the segments are 

 not anchylosed, but the penultimate is arcuate, pedunculate basally 

 and swollen apically; the longer following segment is attached ob- 

 liquely, so as to form an angle but slightly greater than right, and
