258 GEO. H. HORN. 



C'. fiinbriata Mels.— Oval, slightly oblong, very little narrower in front, 

 moflerately convex, piceous, shining, the entire border narrowly, but indefinitely 

 paler. Thorax closely punctate on the disc, more sparsely and less deeply at the 

 sides, the arcuate and transverse series well marked. Elytra near base punctured 

 similarly to the thorax, at ai)ex more sparsely and less distinctly, the usual series 

 of coarse punctures well marked, sutnral stria deeply impressed three-fourths to 

 base. Body beneath opaque black. Femora opaque black, tibiae piceous, tarsi 

 rufescent. Length .18 — .22 inch. ; 4.5— 5.5 mm. 



Presternum simple, mesosternum with a nearly straight, transverse, elevated 

 ridge. 



Claws slender, feebly arcuate, slightly broader at base, similar in the sexes. 



This species resembles Philydrus j)erplextLs, although a little broader 

 in form. In the present genus its form is intermediate between la- 

 custris and rotunda. From both species it differs in the form of the 

 mesosternal ridge. 



When specimens of this species are immature it is not at first 

 sight easy to separate them from specimens of Blanchardi, which 

 may be a little dark from defective preparation, but after one be- 

 comes familiar, by examination, with the shape of the two species 

 there need be no great difficulty, especially as it will be observed 

 that Blanchardi has the head in front of the eyes pale, while in fiin- 

 briata, no matter how immature the specimen may be, the head is 

 of one uniform color. 



Specimens are known to me from Canada, New England States, 

 Pennsylvania and Texas. It is evidently very widely distributed. 



C. Blauchardi n. sp. — Form rather broadly oval, scarcely narrowed in 

 front moderately convex, piceo-ochraceous, head black, with a large pale space in 

 front of each eye. Thorax moderately closely punctate, more sparsely near the 

 sides, the arcuate and transverse series of coarser punctures not very distinct. 

 Elytra similarly punctured, although a little less closely than the thorax and 

 much more sparsely near the apex, the series of coarser punctures indistinctly 

 represented by a few distant punctures, the outermost series alone being dis- 

 tinct, sutural stria well impressed and reaching rather more than two-thirds 

 to base. Body beneath piceous or brown, opaque, rarely black. Femora and 

 tibise brownish, tarsi paler. Length .16 inch. ; 4 mm. 



Presternum simple, mesosternum with a very distinct, straight, transverse 

 ridge, moderately elevated. 



Claws simple and slender in the two sexes. 



This species represents, in its color, hnbeUis of the striate series, 

 althouo-h there is no discal piceous space on the thorax. It is also 

 very like Philydrus ochraceiis, but is more broadly oval in form. 

 The character of the mesosternal ridge is very like fiinbriata. It is 

 the only species of the genus in our fauna in which, with a black 

 head, the sides in front of the eyes are pale, as in many Philydri.
