54 HETEROMERA. [L 



somewhat irregular punctured striae, which become obsolete towards base 

 and apex, and with the reflexed margin narrowed almost from the first 

 ventral segment ; prosternum red, breast and abdomen fuscous ; legs 

 red. L. 2-2 f mm. 



In dead twigs of white-thorn, fir, &c. ; also under bark; very local ; London district, 

 rather common ; Forest Hill, Kipley, Camberwell, Battersea, Coombe Wood, Darenth 

 Wood, Chatham, Cobham, Lee, Esher, Claygate, Hampstead, Southend, &c. ; Tun- 

 bridge Wells ; Sittingbourne ; Kingsgate ; Hastings ; New Forest ; Glanvilles 

 Wootton ; Malvern (one sj edmeii bred from pine twigs with a large number of 

 Pityophthorus micrographics) ; Salford Priors j Knowle and Sinallheath, Birming- 

 ham ; Kepton, Bui tou-ou-Trent. 



Zi cursor, Gyll. (Heyamim, Eedt.). Larger than the preceding, and 

 easily distinguished by having the elytra unicolorous reddish or brown, 

 without yellow patches, and by the subquadrate thorax, the anterior 

 angles of which reach the eyes ; the thorax has the sides evidently den- 

 ticulate, and the disc closely and finely punctured ; the rows of punctures 

 on the elytra are more regular, and the reflexed margin is narrowed fivni 

 the base of the abdomen ; the general colour is lighter or darker reddish- 

 castaneous ; legs red. L. 3 mm. 



Under bark, in dead twigs, &c. ; very rare; first taken at Ockbrook, Derbyshire, 

 by Archdeacon Hey ; Mickleham ; Forest Hill (Marsh); Headley Laue ; Wilmslow 

 near Manchester, taken by Mr. Broadhurst (Chappell). 



RHXNOSXIMEUS, Latreille. 



This is an exceedingly distinct genus, which may at once be known 

 from all our other Heteromera by having the head prolonged into a 

 rostrum, which is variable in length and is more or less dilated, and 

 depressed at apex ; the antennae are long, and are inserted either at or in 

 front of the middle of rostrum ; the thorax is more or less cordate, 

 broader than the head, about half as broad at base as the elytra, which are 

 ovate and convex, and furnished with distinct rows of punctures ; the legs 

 are slender ; the genus contains about fourteen or fifteen species, of which 

 five are found in Europe, three occurring in Britain ; the remainder are 

 widely distributed, representatives occurring in Northern Aeia, North 

 America, Chili, New Guinea, &c. ; It. viridipcnnis is included by several 

 authors under Salpingus. 



The larva of S,. viridipennis (rc.boris, F.) is described by Erichson (Archives de 

 Wicgmau, 1847, i. p. 287) ; it is linear, semicylinclrical and depressed, with the in- 

 teguments chiefly membranous and furnished with scattered hairs ; the head is rather 

 depressed, with five ocelli on each side ; the prothorux is the longest segment, and the 

 last segment is narrower than the rest, Hiid is furnished at apex with two short broad 

 horns which are terminated by two sh;irp slender hooks; the anal appendage is 

 tubiform and retractile, and forms a proleg. 

 I. Rostrum longer tnd more distinctly dilated at apex ; 



antennae inserted between middle and apex of rostium ; 



vertex of head greenish-black ; thorax red . . . . R. KUFICOLLIS, L.
