338 EHYNCHOPHORA. \Cceliodes. 



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 striae 

 and broad shagreened interstices, tuberculate at apex ; legs black, 

 squamose, tarsi more or less ferruginous, femora toothed. L. 8| 4 mm. 

 Male with the posterior tibia3 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 iu 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, &c., from early spring ; Wallasey, Cheshire ; Stretford, 

 near Manchester ; Northumberland and Durham district ; Scotland, scarce, Tweed 

 aud Forth districts. 



M. Bedel (I.e., pp. 165 and 323) separates C. cardui, Herbst. 

 (f/uttula 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 C. CABDTTI, Herbst. 



Head without interocular stria ; thorax with a small 



tubercle on each side, which appears isolated, if viewed 



from above C. FFLiGixostrs, Marsh. 



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 S} r ria ; 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 Europe, 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. 



C. quadrimaculatus, L. (didymus, F. (s,g. Cidncrrhinus, Thorns.)). 

 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, arid 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 striaB, which are 

 almost as broad as the interstices ; legs stout, black, tarsi and tibiae more 

 or less ferruginous, femora toothed. L. 2-3^ mm.
