STAPHYLINID/E. 73 



at their own length from the base, the sides behind them parallel and 

 straight, then rounding to the base, the punctures rather large though 

 feeble, parted by a narrow impunctate line; antennae nearly half as long 

 as the body, slender and pale basally, rapidly very strongly incrassate 

 and infuscate distally, the third joint only a little longer than the second, 

 fourth slightly longer than wide, tenth scarcely one-half wider than long, 

 the last ogival, the basal joint not stout; prothorax relatively small, less 

 than one-half wider than long, widest and with the sides subprominently 

 rounded before the middle, thence subsinuately narrowing to the distinct 

 basal angles, the base rounded; surface finely, sparsely punctate, with a 

 distinct subtransverse ante-scutellar impression; elytra large, transverse, 

 parallel, with rather arcuate sides, nearly one-half wider and a third 

 longer than the prothorax, finely but strongly, not densely punctate, 

 more strongly and closely on the basal slope, the apices scarcely at all 

 sinuate externally; abdomen parallel, with evenly and moderately 

 arcuate sides, at the middle about as wide as the elytra, the surface smooth, 

 minutely, remotely punctulate, with thin side margins, the fourth and 

 fifth tergites equal, strongly transverse; sterna nearly as in loricata 

 but not quite so broad between the coxae. Length 3.0 mm.; width 0.8 

 mm. North Carolina (Tryon). 



Differs from loricata in its much smaller eyes, with the sides of 

 the head behind them less converging, and in its relatively shorter 

 third antennal joint, which, in that species, is very much longer 

 than the second; also in its smaller and shorter prothorax, more 

 angulate at the sides, more sparsely punctate elytra and many other 

 structural characters. 



Myrmedonia criddlei n. sp. Moderately stout and convex, blackish- 

 brown, the prothorax slightly paler externally, the elytra feebly darker 

 externally and toward the scutellum; abdomen black, the first two seg- 

 ments paler, the legs dark reddish-brown; pubescence short and incon- 

 spicuous; head and pronotum finely and very densely chagrined and dull, 

 the elytra more coarsely, very strongly micro-reticulate and more shining, 

 with fine subasperate close-set punctures; abdomen shining, minutely, 

 remotely punctulate; head three-fourths as wide as the prothorax, as 

 long as wide, the eyes rather large, prominent, the sides behind them a 

 little shorter and rapidly convergent and broadly arcuate to the base; 

 antennae extending to the elytral apex, very stout, gradually incrassate, 

 testaceous in color throughout, the outer joints nearly one-half wider 

 than long, second much shorter than the third, which is strongly obconic, 

 somewhat compressed, the first five or six joints (cf ) bristling within 

 with long pale hairs; prothorax two-fifths wider than long, nearly as in 

 the preceding, the sides not quite so prominently rounded before the 

 middle, the median line finely impressed throughout, without basal 

 impression; elytra transverse, truncate, a fourth or fifth wider than the 

 prothorax and of equal length; abdomen fully as wide as the elytra, 

 parallel, with the sides only very slightly arcuate; sterna nearly as in
