338 RHYNCHOPHORA. [ Caliodes. 
there is a very distinct velvety black patch, which will easily distinguish 
the insect; thorax closely punctured, with a central furrow which is 
more or less interrupted in middle ; elytra with fine punctured striz 
and broad shagreened interstices, tuberculate at apex; legs black, 
squamose, tarsi more or less ferruginous, femora toothed. L. 33-4mm. 
Male with the posterior tibize armed with a hook at apex and the last 
ventral segment deeply and broadly impressed in the middle. 
By sweeping herbage; often on roads and pavements; also found in moss and 
under decaying seaweed and in sand-pits ; rather local, less common in many districts ; 
London district, common everywhere; Southern districts, widely distributed ; Mid- 
land counties, very local and apparently scarce, Bewdley, Repton, &c. ; Lincoln, 
abundant on pavements, &e., from early spring; Wallasey, Cheshire ; Stretford, 
near Manchester; Northumberland and Durham district; Scotland, scarce, Tweed 
and Forth districts. 
M. Bedel (l.c., pp. 165 and 323) separates C. cardui, Herbst. _ 
(guttula F.) and C. fuliginosus, Marsh, which are usually considered 
as synonymous, as follows :— 
Head with a little stria between the eyes; thorax with 
a lateral raised ridge or tubercle on each side, which is 
rather strongly developed and continued as far as the 
external border, if viewed from above . ... . 
Head without interocular stria; thorax with a small 
tubercle on each side, which appears isolated, if viewed

The former of these species M. Bedel records as being found in sandy 
places and on sand-hills in spring and autumn, and as occurring in 
Central Europe, Western Siberia and Syria; the latter, he says, is found 
in sandy districts and often under shady walls, and occurs in early 
spring and summer; it inhabits the whole basin of the Seine, Central 
and Southern Eurcpe, Algeria and Madeira; the larva has been found 
by Rupertsberger at the roots of Papaver somniferum. 
It is possible that these two species may be distinct, but, as far as I 
have been able to judge, intermediate specimens occur, and I should be 
sorry to separate them on the characters given by M. Bedel unless they 
were more marked, 
Cc. quadrimaculatus, L. (didymus, F. (s.g. Cidncrrhinus, Thoms.) ). 
Short and broad, convex, dull black, clothed beneath with thick whitish 
or yellowish-white scales, which are also present in spots and patches on 
the upper surface, the most conspicuous being at about the middle of 
the sides; the base, apex, and sometimes part of suture, are also more or 
less plainly whitish, but the markings are not conspicuous, and the pre- 
vailing colour of the upper surface is black ; thorax strongly and very 
coarsely punctured with a shallow central furrow, and with distinct 
lateral tubercles ; elytra with rather strong punctured striz, which are 
almost as broad as the interstices ; legs stout, black, tarsi and tibia more 
or less ferruginous, femora toothed, L. 2-3; mm.
