48 MEMOIRS ON THE COLEOPTERA. 



black, the elytra rather dark and uniform brown-flavate, the legs pale; head 

 moderately transverse, the eyes longer and more prominent than the tempora, 

 which are parallel, rounding basally, the carinse very fine, not entire; antennae 

 rather short, much thicker amd more strongly incrassate distally than in the 

 three preceding, the outer joints strongly transverse, the last stout, oval, 

 pointed, rather longer than the two preceding, the second and third elongate, 

 equal ; prothorax transverse, distinctly wider than the head and narrower than 

 the elytra, the parallel sides moderately arcuate, rather more so before the 

 middle than basally, scarcely impressed; elytra distinctly transverse though 

 much longer than the prothorax; abdomen parallel throughout, narrower 

 than the elytra, the fifth tergite but slightly longer than the fourth, the sixth 

 in the type broad, very feebly and gradually sinuato-truncate medially at 

 tip; mesosternal process extending to nearly apical fourth of the coxae, 

 gradually prolonged but only moderately slender at apex, well separated 

 from the short and broadly angulate, rather blunt metasternum, the inter- 

 vening ridge very broadly convex; hind tarsi with the joints moderately 

 slender, the first but slightly shorter than the second. Length 2.3 mm.; 

 width 0.5 mm. New York (Catskill Mts.). 



This species resembles the preceding in the tarsi, sterna and 

 carinse of the head, but differs in sculpture and in the structure of 

 the antennae. 



Donesia n. subgen. 



This name is proposed for a small species, at first sight resembling 

 the preceding but distinguishable by the form of the head and the 

 complete absence of all trace of infra-lateral carinae; the type is 

 the following: 



Atheta (Donesia) temporalis n. sp. Nearly parallel, rather depressed, 

 subalutaceous, very finely and distinctly micro-reticulate throughout, more 

 feebly on the abdomen, the punctures extremely fine, close but wholly in- 

 conspicuous; color piceous-black, the elytra and legs but slightly paler, 

 piceous; head rather well developed and transverse, the eyes somewhat 

 small, strongly convex, at a little more than their own length from the base, 

 the parallel tempora broadly arcuate and sensibly more prominent than the 

 eyes; antennae not very stout, very gradually and feebly incrassate, piceous 

 throughout, extending to about the middle of the elytra, the second joint 

 cylindric, about as long as the more obconic third, tenth slightly wider than 

 long, the eleventh as long as the two preceding ; prothorax transverse, almost as 

 wide as the elytra but much wider than the head, the parallel sides feebly arcu- 

 ate, straighter basally, the angles obtuse though rather distinct, the median 

 line very faintly impressed ; elytra very moderately transverse, much longer 

 than the prothorax; abdomen narrower than the elytra, parallel basally, 

 thence very feebly narrowed to the apex, the fifth tergite much longer than 

 the fourth, the sixth in the type notably narrow, the apex feebly and gradually 

 sinuate in about median third; mesosternal process extending only slightly 

 behind the middle of the coxae, the apex gradually prolonged and very finely
