258 ROYNCHOPHORA. [ Orchestes. 
connate on vertex; thorax bisinuate at base with a more or less distinct 
dorsal channel; elytra with rather fine punctured striw, with a large 
triangular common patch (often more or less abraded) extending from 
the shoulders to beyond the middle of the suture, densely clothed with 
pale pubescence, the rest of the surface being less densely pubescent ; 
anterior and intermediate femora each with a minute spine in the 
middle, the posterior with a double series‘of six or seven spines on each. 
L. 23-35 mm. 
ne oaks; generally distributed and common throughout the greater part of the 
inguom. 
O. scutellaris, Gyll. Longer and narrower than the preceding, 
oblong, rufo-ferruginous above, underside and apex of rostrum black, 
clothed with ashy pubescence, which is thick and lighter on scutellum ; 
antenne inserted near base of rostrum, with the scape much shorter 
in proportion than in the preceding species; thorax rather strongly 
punctured, obsoletely channelled, with the sides narrowed in front 
and slightly narrowed behind; elytra with rather deep punctured 
stri#, interstices somewhat shining and rugose ; anterior femora nar- 
rowed, posterior with a small tooth in the middle; anterior cox con- 
tiguous; pubescence of episterna of metasternum very close. L. 
23-3 mm. 
On alder and wild cherry ; rare; Coombe and Darenth Woods, Carlisle and Sketty, 
near Swansea (Stephens) ; Norfolk (F. Smith); Lowestoft; Bearsted (Gorham) ; 
Sandown ; Deal; Glanvilles Wootton (Dale) ; Stretford, near Manchester (Reston) ; 
Northumberland and Durham district (Bold); Scotland, very rare, Solway and 
Dee districts (Sharp) ; Ireland, near Belfast (Haliday); there has been some con- 
fusion regarding this insect, and it is possible that mistakes may have arisen with 
regard to some of these localities. 
V. semirufus, Gyll. In this variety the head and thorax and often 
the legs are dark, whereas in the type form they are red; the legs, how- 
ever, are very variable in colour; according to Stephens the posterior 
femora, which in the type have only a single small tooth in the middle, 
are in the variety armed with several small teeth; it seems possible 
that it may be a distinct species. L. 25-3 mm, 
On alder and wild cherry; very local; St. George’s Hill, Weybridge (Stevens) ; 
Woking (where Mr. Champion has taken it not uncommonly unaccompanied by the 
type form). 
O. alni, L. Blick, pubescent, with the antenna, tarsi, thorax, anal 
segment of the abdomen and elytra rufo-testaceous, the latter with four 
black spots, which are very variable, the apical ones being often united 
at suture, often very obscure, and sometimes wanting; antenne with 
the scape long, inserted just behind middle of rostrum ; thorax closely 
aud rather strongly punctured, sometimes with an abbreviated black 
patch in the middle of disc ; elytra with strong punctured striz ; pos-
