PSELAPHIDAE. 519 



narrowed at its base ; joints 3-7 quite oblong, eighth quadrate ; ninth 

 and tenth generally oblong, the latter sometimes shorter, the terminal 

 very elongate-oval, yet scarcely as long as preceding two combined. 



Mandibles broad near the base, curvate and acute towards the extremity, 

 each minutely quadridentate inwardly. 



Maxillary palpi of only moderate length, their basal joint minute, second 

 elongate and gradually incrassate, the next short, subquadrate, fourth 

 elongate-oval and pubescent. 



Legs simple ; basal joint of tarsi short, the others elongate, with single 

 claws. 



Male. — Underside of head with an obtuse tubercle near each side, at 

 the base, of the subquadrate mentum. Prosternum not carinate along 

 the middle. Ventral segments 2-5 diminish, the first covered by the 

 femora ; the second with a band of minute brassy scales across its 

 extremity ; sixth twice the length of fifth at the sides, deeply emarginate 

 at the middle, rounded towards the sides ; seventh broadly conical, occupy- 

 ing the emargination of the sixth, and in my reversed specimen somewhat 

 depressed. 



M. Raffray in his collection at Rome has upwards of 130 genera of 

 Ewplectini. The elongate antennal articulations of Neosampa, its oviform, 

 uni-sulcate thorax, ample elytra, Eupines-\ike head, simple prosternum, 

 and the structure of the ventral segments of the male, taken together, 

 differentiate the present genus. 



4039. Neosampa granulata sp. nov. 



Nitid, elytra and hind-body subparallel, the whole surface with minute, 

 but not close, granular or tubercular sculpture ; rufo-castaneous, tarsi and 

 palpi a little paler ; the pubescence yellow, distinct, moderately elongate, 

 erect behind. 



Head plane in front, the ill-defined foveae prolonged forwards as broad 

 grooves but becoming obsolete near the forehead. Thorax of about equal 

 length and breadth, widest near the milddle ; discal groove shallow and 

 narrow in front, expanded and foveiform behind. Elytra hardly twice the 

 length or breadth of thorax, a little narrowed near the base ; sutural striae 

 subpunctiform at the base, humeral impressions broad there, indistinctly 

 prolonged towards the middle, with feebly cariniform inner borders. Hind- 

 body shorter than elytra, remotely and indefinitely sculptured ; first un- 

 covered segment in both sexes, at the base, with a median depression, this 

 is subtuberculate at each side ; second rather shorter, the others deflexed. 



Underside nitid, metasternum rather thickly pubescent and broadly 

 impressed along the middle. 



Fern. — Sixth ventral segment simple, larger than fifth ; almost the only 

 character which differentiates that sex from the male. 



Length, 2 mm. ; breadth, f mm. 



Boulderstone Cleek and Scarcliff, near Mount Algidus. Four individuals 

 found by Mr. T. Hall on the 18th October, 1913. 



Anabaxis Raffray. Gen. Ins. (Wytsm.), Pselaphidae, p. 252. 



4040. Anabaxis minor sp. nov. 



Suboblong, sUghtly convex, nitid ; light castaneo-rufous, tarsi and palpi 

 flavescent ; sparingly clothed with greyish, rather short, depressed, and a 

 few longer suberect hairs.
