310 Coleopterological Notices, V. 



slender, very slightly incrassate, rather more than attaining the middle of the 

 elytra, the first three joints elongate, subequal, the first slightly the stoutest, 

 fourth distinctly longer than wide, tenth just visibly wider than long, eleventh 

 small, conoidal, pointed, not as long as the two preceding. Prothorax but 

 slightly wider than long, widest just before the middle, the sides broadly 

 arcuate and distinctly convergent anteriorly, much more feebly convergent 

 and distinctly sinuate to the base which is broadly arcuate and much wider 

 than the apex ; apical angles greatly defiexed and rounded ; basal obtuse and 

 distinctly rounded ; disk strongly convex, very obsoletely impressed along the 

 median line, with a feeble rounded impression in the middle just before the 

 base. Elytra large, quadrate, two-fifths wider and longer than the prothorax ; 

 sides subparallel ; humeri broadly exposed at base ; surface strongly, broadly 

 impressed just behind the scutellum ; suture excessively finely margined. 

 Abdomen rather longer than the anterior parts, distinctly narrower than the 

 elytra ; sides parallel, becoming feebly convergent near the apex ; border 

 rather deep ; first three segments strongly, the fourth feebly, impressed at 

 base ; fourth and fifth subequal ; sixth exposed, rounded. Legs moderate in 

 length, slender ; posterior tibiae very slender, nearly equally thick through- 

 out, the tarsi much shorter, filiform, the basal joint rather longer than the 

 next two and fully as long as the last. Length 4.0 mm. ; width 0.95 mm. 



Yancouver Island. Mr. Wickham. 



The middle coxas are large oblique and narrowly separated, the 

 acetabula deep and acutely limited on all sides except the long 

 isthmus, which separates the acute apex of the prosternal process — 

 extending two-thirds the length of the coxae — from the extremely 

 short obtuse metasternal process, the latter scarcely entering at all 

 between the coxae. The neck is much wider than in puncticollis.

It is difficult to understand just why this genus is still placed 

 among the allies of Atheta, for in my specimen of rigidicornis 

 from the Caucasus, the anterior tarsi are as distinctly five-jointed 

 as in any species of Aleochara ; the facies also indicates its affinity 

 with ll3^obates. 



C. pilljerulUS n. sp. — Subparallel, moderately stout, convex, slightly 

 shining, the abdomen polished, dark brown, the elytra, apices of the tergites, 

 legs and basal parts of the antennae paler, obscure rufous ; punctuation of the 

 head rather strong and moderately sparse, of the pronotum finer, very dense 

 and rather feeble, of the elytra coarser, rather close and subasperate, of the 

 abdomen moderately sparse but distinct, subasperate, extending to the base 

 of the segments ; pubescence rather long, dense and conspicuous, sparse on 

 the abdomen. Head orbicular, longer than wide, only slightly but distinctly 

 narrower than the prothorax, even, convex ; eyes at much more than their own
