lected together at the radius and bordered narrowly with pitch-brown, are apt to 

 produce a small spot by the confluence of their boi'dering ; the weaker of the

 neighbouring membrane only very slightly tinged with yellowish amber-grey ; 

 pterostigmatic region also very slightly tinted with pale sepia-grey. Body dull 

 pitch-broAvn above ; the apical borders of the abdominal segments, especially at the 

 sides, darker, the darker colour extending thereabouts towards the base obliquely 

 below a brown-ochreous space at the base of the segment ; posterior lateral angles 

 of the dorsum of the penultimate segment produced acuminately, somewhat as in 

 ^. armatus. Venter pitch-brown, with bright brown-ochreous joinings ; the de- 

 pressions in the neighbourhood of the genitalia also brown-ochreous or ferrugineous.

DESCKIPTION OF A NEW SPECIES OF REIZOPEAQUS. 

 BY W. G. BLATCH, F.E.S., AND A, C. HORNER, E.E.S. 



Ehizophagus oblongicollis, sp. n. 



General appearance. — Of a ferruginous colour throughout, although the head 

 and thorax are occasionally somewhat dusky or pitchy ; it is more convex or cylin- 

 drical than the other species, except R. nitidulus, to which it most nearly approaches. 



Head rather elongate, very slightly narrowed behind, scarcely as wide as 

 thorax, uniformly punctured, the punctures being distinct but not close, scarcely if 

 at all impressed on each side of forehead. Eyes rather small, and not very promi- 

 nent. Antennae ferruginous ; 1st joint large, dilated on the inner side, 2nd sub- 

 globose, 3rd elongate, about 1^ times as long as 2nd, 4th lo 8th short, length and 

 width about equal, 9th a little larger and slightly transverse, club ovate. Thorax 

 oblong, parallel-sided, all angles completely rounded oft', margined at sides and base 

 punctuation not close, a little stronger than that of head, a distinct but very small 

 narrow space behind centi*e smooth, base gently emarginate. Scutellum with an 

 impression at apex. Elytra elongate, narrowed behind, rather finely and closely 

 punctured in regular rows, the sutural rows only being in evident striae, punctuation 

 at sides finer than on disc, interstices equal, fiat, and finely aiutaceous, the sutural
