Ceuthorrhynchus. | RHYNCHOPHORA. 359 
tarsi slightly ferruginous ; underside thickly clothed with white scales; 
thorax moderately long with the sides and front thickly clothed with light 
scales, which are also present on a short band at base, lateral tubercles 
strong, black, completely surrounded by the scales, margins strongly 
constricted before apex ; elytra with a cruciform spot of white scales 
at base of suture, and a lunate band on each side and other markings 
towards apex, punctured strie rather fine, interstices rather broad, 
rugose ; femora strongly toothed, claws simple rather slender, L. 3-4 
mm, 
Male with all the tibiz armed with a strong hook and the last 
ventral segment of abdomen slightly impressed. 
Female with the tibiz simple, the teeth of the femora stronger, and 
the elytral markings larger. 
On thistles; local but not uncommon and generally distributed throughout the 
kingdom. 
C. trimaculatus, F. (crucifer, Ol.). Very like the preceding in 
general appearance, but easily distinguished by the scutellary patch, 
which is yellowish in the middle with a white patch and small spot on 
each side, and by the fact that the tubercles of the thorax are not 
surrounded with white scales, as well as by the light reddish testaceous 
tarsi ; the antenne also are reddish, except the club ; the teeth of the 
femora are strong and the tarsal claws are simple and rather slender. 
L. 3-4 mm. 
On thistles ; local and much less common than the preceding; Mickleham, Cater- 
. ham, Shirley, Purley, Headley Lane, Chatham; Dover; Folkestone; Hastings ; 
Littlehampton ; Brighton; Portland; Glanvilles Wootton; Whitsand Bay, Ply- 
mouth; Swansea; Ashbourne, Derbyshire; Scarborough; Ireland, Armagh, one 
specimen (Rey. W. F. Johnson). 
CEUTHORRHYNCHIDIUS, Duval. © 
This genus contains comparatively few species, seventeen only being 
recorded in the Munich catalogue of 1871, all of which, with the ex- 
ception of one from South Africa, are recorded from Europe ; in the 
European catalogue, however, of Heyden, Reitter and Weise, published 
in 1883, twenty-four species are enumerated ; about sixteen of these 
have been recorded as British ; they are very closely allied to the species 
of Ceuthorrhynchus, but are, on the average, considerably smaller, 
although one or two species, e.g. C. horridus, are comparatively large : 
they may be distinguished from the three preceding genera (Celiodes 
Poophagus and Ceuthorrhynchus) by having the eighth joint of the 
antenne included in the club and the funiculus consisting of only six 
joints ; this distinction, it must be allowed, does not always appear to 
be very evident as certain species have been placed in both genera by 
different authors ; from Zapinotus the species may easily be known by
