Cryptocephalus.'] PHTTOPHAOA. 291 



interstices somewhat convex ; the colour is bluck with a spot at 

 apex of elytra rufo- testaceous; in the male the fifth ventral segment is 

 more strongly impressed, the impression being punctured ; there is a 

 rare variety of C. bii>unctatus, (v. Thomsoni,) which very closely re- 

 sembles this species, but which differs, according to Weise, in having 

 the spot at apex narrower and more in the form of a band and less 

 rounded and widened on its anterior edge ; very few specimens have 

 occurred in Britain, and it seems still doubtful whether they should, 

 either all, or in part, be referred to C. ligutlattts or 6*. Hpunctatus, if 

 these two latter species be really distinct; this has been doubted by some 

 authors, who have united them. L. 4|-6 mm. 



On young trees; very rare; Bournemouth (Kemp Welch); Lyndhurst; Chat 

 Moss, on Eriophorum polystachyum, eight specimens (Chappell). 



C. aureolus, Suffr. (sericeus, Ktist., nee F.). A rather large species, 

 of a silky-green colour, sometimes golden, coppery or violaceous, shining; 

 head rather strongly punctured, antenna black ; thorax distinctly 

 punctured, considerably narrowed in front and strongly sinuate at base ; 

 scutellum long, raised at apex ; elytra strongly and rugosely punctured, 

 with traces of raised lines towards apex ; legs metallic, all the tarsi 

 dilated. L. 5}-7| mm. 



Male with the last ventral segment transversely impressed, emargi- 

 nate at apex. 



Female with the last ventral segment deeply emarginate at apex. 



On flowers, especially Compositao (Hieracium, <lc.); locally common ; London district, 

 common, Croyclon, Caterham, Mickleham, Reigate, Weybridge, Woking, Chatham,

 pool ; Northumberland and Durham district ; not recorded from Scotland. 



C. hypocheeridis, L. (siricetis, F., nee Kust., L. &c.). Very like 

 the preceding, but smaller, with the antennae distinctly shorter, and the 

 pygidium emarginate at apex and furnished with a more or less distinct 

 carina ; the scutellum is shorter and more raised at apex ; the elytra are 

 rather less strongly sculptured ; the male has the fifth ventral segment 

 marked with a shallower fovea which has the apex slightly emarginate and 

 furnished with a transverse and somewhat elevated line in the middle 

 of the posterior margin, and the female has the fovea of the fifth ventral 

 segment deep and ciliate at base. L. 45^ mm.

 Croydon, Shirley, Mickleham, Darentli, Chatham, Rochester, Headley Lane ; Dover; 

 Folkestone; Hampshire; Devon (on Crepis tectorum (circns)) ; Northumberland and 

 Durham district, Marsden (J. Hancock). 



C. ochrostoma, Har. (uitululus, Gyll.). Smaller en an average 

 than either of the preceding, from which it may be at once known by 

 having the base of the antennae and more or less of the legs reddish or
