Cryptocephalus. | PHYTOPHAGA, 291 
interstices somewhat convex; the colour is black 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. bipunctatus, (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. biguttatus or C. bipunctatus, if 
these two latter species be really distinct; this has been doubted by some 
authors, who have united them. L. 43-6 mm. 
On young trees; very rare; Bournemouth (Kemp Welch); Lyndhurst; Chat 
Moss, on Eriophorum polystachyum, eight specimens (Chappell). 
C. aureolus, Suffr. (sericeus, Kiist., nec F.). Arather large species, 
of a silky-green colour, sometimes golden, coppery or violaceous, shining; 
head rather strongly punctured, antenne 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. 53-72 mm. 
Male with the last ventral segment transversely impressed, emargi- 
nate at apex. 
Female with the last ventral segment deeply emarginate at apex.

pool ; Northumberland and Durham district ; not recorded from Scotland. 
C. hypocheeridis, L. (sericeus, F., nec Kiist., L. &c.). Very like 
the preceding, but smaller, with the antenne distinctly shorter, and the 
pygidium emarginate at apex and furnished with a more or less distinct 
earina ; 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. 4-5} mm.

Croydon, Shirley, Mickleham, Darenth, Chatham, Rochester, Headley Lane; Dover; 
Folkestone ; Hampshire ; Devon (on Crepis tectorum (virens)) ; Northumberland and 
Durham district, Marsden (J. Hancock). 
CG. ochrostoma, Har. (vitidulus, Gyll.). Smaller cn an average 
than either of the preceding, from which it may be at once known by 
having the base of the antenne and more or less of the legs reddish or
