PSELAPHIDAE. 605 



Antennae equalling head and thorax in length, their second joint as 

 long as the rather thicker first, third rather shorter, narrowed towards its 

 base, fourth shorter than fifth, which latter equals the third, 6-8 small and 

 moniliform ; ninth much enlarged, narrowed towards its apex, tenth still 

 broader, strongly transverse, eleventh about as long as preceding two 

 combined, conical and acuminate. 



Underside concolorous. Prosternum feebly carinate. Metasternum large, 

 convex. Basal ventral segment ciliate, not fully uncovered, second largest, 

 3-5 successively decrease, sixth about as long as second, its deep emargina- 

 tion occupied by the subquadrate operculum. 



This somewhat resembles some of the Scydmaenidae. In form and 

 sculpture it differs greatly from the type of the genus, 2460. The rather 

 narrow, oviform thorax has a well-marked transverse depression in front 

 of the base, but there is hardly any trace of the usual conspicuous channel 

 along the middle. 



Euglyptus is well described by M. Kaffray in Wytsman's Gen. Ins., 

 Pselaphidae, p. 51.

4170. Dalma graniceps sp. nov. 



Nitid, castaneo-rufous, legs and antennae paler, tarsi testaceous ; 

 pubescence yellow, distinct and suberect ; body moderately elongate and 

 subdepressed. 



Head smaller than thorax, obliquely narrowed behind the rather pro- 

 minent eyes, the foveae between these prolonged forwards, its sculpture 

 consists of distant, fine, lotundate granules. Thorax as long as broad, 

 widest before the middle, more gradually narrowed behind than in front, 

 apparently minutely, sparingly, and indefinitely granulate ; lateral foveae 

 situated between the base and the middle, only indistinctly prolonged 

 beyond that point ; the central angular fovea is large and deep, and the 

 rather broad furrow proceeding from it nearly reaches the apex but is more 

 slender there. Elytra about a third longer and broader than thorax, a 

 little narrowed towards the base, with rounded shoulders, their sculpture 

 fine and indistinct ; sutural striae well marked, the impression near each 

 shoulder moderately deep and broad, with a cariniform elevation separating 

 it from the sutural stria. Hind-body of about the same length and width 

 as the elytra, indistinctly sculptured, its first uncovered segment has a 

 depression across the base. 



Antennae as long as head and thorax ; basal joint rufous, stout, cylin- 

 clric, half as broad as long, the next equally thick and almost oblong, third 

 rather smaller, obconical ; joints 4-6 transversely moniliform and almost 

 equal ; seventh and eighth strongly transverse ; ninth largest, subquadrate, 

 somewhat curvedly narrowed towards its inner extremity, foveate near 

 inner side underneath ; tenth quadrate, obviously smaller, its basal and 

 apical angles at one side slightly prominent ; terminal joint as long as 

 preceding two combined, elongate-conical and acuminate. 



Underside concolorous, apparently finely punctate, distinctly pubescent. 

 Head distantly and finely granulate, bearing some outstanding elongate
