Tychius.] RHYNCHOPHORA. 301 
There seems to be considerable confusion with regard to the two 
preceding species, more especially 7. junceus; I have several specimens 
of both 7. tomentosus and T. junceus from Dr. Power’s collection before 
me, and the latter insect is smaller and narrower and more grey in 
appearance than the former, and has the suture of the elytra uni- 
colorous; Thomson, however (Skand. Col. vii. p. 302), speaks of 
T. junceus as broader than 7. tomentosus, and as having the suture fur- 
nished with white scales; he mentions, however, that the femora and 
rostrum are darker in the former species, which appears to be the case ; 
in some way or other he seems to have confused the two insects, which 
are certainly closely allied ; the deseriptions of Sch6énherr referred to by 
Thomson (Gen. et Spec. Cure. III. 411, 15 & 412, 17), are very slight 
and of little practical use in separating the two species. 
T. tibialis, Boh. (nigrirostris, Wat.). Oblong, convex, black with 
the antenne, tibie and tarsi red, apex of the former dark; upper side 
covered with uniform grey pubescence, which is lighter on the under- 
side ; rostrum dark, reddish at apex; thorax subtransverse, with the 
sides rounded, usually with a fine fringe of white hairs at base; elytra 
rather long, with distinct striz, which are not covered by the pubescence ; 
femora dark, tibize usually more or less infuscate at extreme base. 
L. 2-23 mm.

mouth district ; Trench Woods, Bromsgrove. 
T. pygmeeus, Bris. (brevicornis, Wat.; pusillus, Germ.?), Ex- 
tremely like the preceding, and chiefly distinguished by its very small 
size; oblong, convex, black, with the antennz red at base and dark at 
apex; underside with fine white scales, upper surface with grey 
pubescence ; rostrum dark ; thorax subtransverse with the sides moder- 
ately rounded ; elytra with distinct punctured striae, pubescence 
often thicker on suture ; femora dark, tibie and tarsi red. L. 14-1}

Six European species belong to this genus; they differ in no way 
from the ordinary species of Tychius except in the fact that the funi- 
culus of the antennz is six-jointed; like them they are found on 
Papilionacee ; our single species is the commonest member of the tribe 
that is found in Britain. 
M. picirostris, F. Oblong, convex, black, with the base of the 
antenne and the tibia and tarsi ferruginous, apex of the former and
