54 HETEROMERA. [ Lisscdema. 
somewhat irregular punctured strie, which become obsvlete 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, 2-25 mm. 
In dead twigs of white-thorn, fir, &c. ; also under bark; very local ; London district, 
rather common; Forest Hill, Ripley, 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 specimen bred from pine twigs with a large number of 
Pityophthorus micrographus) ; Salford Priors; Knowle and Smallheath, Birming- 
ham ; Repton, Burton-on-Trent. 
ZL cursor, Gyll. (Heyanum, Redt.). 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 from 
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 Lane; Wilmslow 
near Manchester, taken by Mr. Broadhurst (Chappell). 
RHINOSIMUS, Laireille. 
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 antenne 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 Asia, North 
America, Chili, New Guinea, &c.; 2. viridipennis is included by several 
authors under Salpingus. 
The larva of R. viridipennis (roboris, F.) is described by Erichson (Archives de 
Wiegman, 1847, i. p. 287); it is linear, semicylindrical 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 prothorax is the longest segment, and the 
last segment is narrower than the rest, and is furnished at apex with two short broad 
horns which are terminated by two sharp slender hooks; the anal appendage is 
tubiform and retractile, and forms a proleg. 
I. Rostrum longer and more distinctly dilated at apex ; 
antenne inserted between middle and apex of rostium ; 
vertex of head greenish-black ; thoraxred . . . . R. RUFICOLLIS, L.
