436 MEMOIRS ON THE COLEOPTERA 



resembles an unusually stout <zneus, and in reality it should stand 

 next to that species in the lists and be not separated by many 

 unrelated species as is necessary in the arrangement of Dr. Horn; 

 the anterior tarsi in the male of eeneus itself are only very moderately 

 dilated. 



The following is so totally unlike any other species of Philonthus 

 known to me, that I am in doubt as to its true affinities: 



Philonthus nematocerus n. sp. Moderately slender, rather convex, 

 shining, dark piceous-brown in color, the head blacker ; legs rufous, piceous 

 distally; antennae ochreous, blackish basally, extremely long and slender, 

 not incrassate, extending to the basal parts of the elytra, all the joints 

 very much elongated, the fifth and sixth two and one-half times as long 

 as wide; head subquadrate, as wide as long, with numerous strong punc- 

 tures on the lateral parts and, behind the eyes, three large fovese in 

 triangle, each bearing a long seta; eyes rather convex, between two and 

 three times their length from the base, the tempora forming an even 

 broad curve from near the eyes to the base- prothorax oval, a fourth longer 

 than wide, scarcely as wide as the head, widest at apical two-fifths, the 

 sides broadly rounded, slightly converging and straight basally, the base 

 broadly arcuate, the angles widely rounded; surface very convex, smooth, 

 the series having three discal punctures, which are very fine; scutellum 

 finely, sparsely punctured, scarcely more than a third as long as the suture; 

 elytra much longer than wide, much wider and longer than the prothorax, 

 the sides feebly arcuate posteriori}'; subsutural impressed lines broad and 

 feeble; punctures fine and rather sparse, the hairs moderately long, well 

 separated; abdomen arcuately tapering from near the base, finely, sub- 

 asperately, evenly and rather sparsely punctate, the segments not trans- 

 versely impressed basally; sixth ventral (9 ) circularly rounded; anterior 

 tarsi thick; legs very long and slender. Length (9) 10.5-10.8 mm.; 

 width 1.9 mm. British Columbia (Metlakatla), Keen. 



This species is not allied distinctly to any other of our Philonthi 

 and, in fact, may prove to differ at least subgenerically; the tarsal 

 claws are very long, arcuate and extremely slender. 



The two following species belong to the section having four 

 discal punctures in the pronotal series: 



Philonthus molliculus n. sp. Form rather stout posteriorly, narrow 

 and attenuated anteriorly, polished throughout, pale red-brown in color, 

 the head and abdomen slightly more obscure; legs pale; head convex, 

 parallel, oval, slightly elongate, the sides evenly arcuate, rounding broadly 

 at base; eyes small, slightly convex, at fully twice their length from the 

 base; antennae brown, not quite as long as the head and prothorax, rather 

 stout and incrassate, the outer joints slightly shorter than wide, the third 

 but very little longer than the second; prothorax subequal in width to 

 the head, barely perceptibly wider, very elongate, subparallel, the sides
