STAPHYLINID/E. 83 



Atheta (Lamiota) profecta n. sp. More elongate and parallel, moder- 

 ately, the abdomen strongly, shining, the transverse fine wavy strigilation 

 of the latter almost obsolete; punctures fine, not close, not asperate, 

 sparse on the abdomen, the vestiture rather long, pale and coarse; 

 color rufo-piceous, the elytra paler and more flavate, the abdomen dark 

 testaceous, with a blackish subapical cloud, the legs pale; head as in 

 the preceding but larger and more transverse, the eyes at their own length 

 from the base, the tempora converging and broadly arcuate behind them 

 to the base, the carinee fine and subentire; antennae long, pale piceous, 

 paler basally, gradually moderately incrassate distally, the third joint 

 longer than the second, fourth longer than wide, sixth as long as, and 

 the tenth nearly as long as, wide, the last pointed from near the base 

 and nearly as long as the two preceding; prothorax parallel, more than 

 one-half wider than long, a fourth wider than the head, widest near 

 apical third, where the sides are broadly rounded, straighter basally; 

 elytra only just visibly wider, the suture about a third longer, than the 

 prothorax, the apices sinuato-truncate externally; abdomen slightly 

 narrower than the elytra, parallel throughout, with nearly straight sides, 

 the margins thin, the fourth and fifth tergites equal, the sixth (c?) 

 arcuate and strongly crenate between the lateral processes, which are 

 rather short and thick. Length 3.3 mm.; width 0.76 mm. British 

 Columbia (Metlakatla), Keen. 



Allied to the preceding rather than keeni, but differing in the paler 

 coloration, larger head and prothorax and longer and more slender 

 antennae; the male sexual characters are similar, except that the 

 lateral processes of the sixth tergite are a little shorter and thicker. 

 The head in the male is feebly impressed at the centre of the upper 

 surface, the pronotum broadly and moderately impressed along the 

 median line from apex to base, but without the broad depression 

 of achromata and keeni. 



The following species is much smaller and differs in sculpture 

 and sexual characters: 



Atheta (Lamiota) concessa n. sp. Stout, subparallel, rather strongly 

 shining, the reticulation fine, moderately strong, large but feeble and 

 polygonal throughout the abdomen, the punctures relatively closer and 

 more asperate than in the two preceding, the pubescence nearly similar 

 but closer; color deep black, the elytra dark piceous-brown, feebly in- 

 fumate extero-posteriorly and suturo-basally, the legs pale; head well 

 developed, wider than long, parallel at the sides, the eyes feebly convex, 

 at fully their own length from the base, the equally prominent tempora 

 parallel and straight, then abruptly very oblique to the base, the carinae 

 fine, not quite entire; antennae black, slightly pale basally, moderate in 

 length, gradually and rather strongly incrassate, the second and third 

 joints subequal, fourth scarcely longer than wide, the outer joints rather 

 strongly transverse, the last longer than the two preceding; prothorax
