5 (8.). Anterior logs, beneath, without long bristly hairs. The elytra without 

 intermixed fuscous hairs. The eyes of $ not very large and convex. Yertex not, 

 or very indistinctly, carinate. 



6 (7.). Fourth joint of antenna? scarcely twice, or a little less than twice, 

 shorter than the third, and distinctly longer than the first. The genital segment of 

 $ broader than the preceding ones ; the forceps very large, the right lobe bidentate, 



on the left lobe the teeth very long-produced O. prasinus, Fall. 



7 (6.). Fourth joint of antennae twice (<?)> or more than twice (?), shorter 

 than the third, and scarcely (?), or very little, longer (3) than the first. The 

 genital segment of <$ scarcely broader than the others; the forceps moderate, the 

 right lobe bidentate, with the teeth short, almost equal O. Scotti, Reut. 



8 (5.). Anterior legs, beneath, with a series of long, pale, bristly hairs. Hemi- 



elytra often (especially in the 6*) with rather numerous intermixed fuscous hairs. 



Vertex carinate, in the S almost narrower than the very convex, prominent and 



large eye. Eyes, in 6* , above, approaching each other. Antenna? (especially in $ ) 



rather robust, very densely and finely fuscous-pubescent ; third joint only one-seventh 



or one-eighth (<?), or one-fifth to one-fourth (?) shorter than the second, and two 



and one-third — almost three times — longer than the fourth ; fourth joint a9 long 



as, or scarcely longer, than the first. G-enital segment, of S small.

Globiceps fulyipes, I. c, No. 171. In vol. xv, p. 66, I have 

 given the differential characters oifulvipes, Keut., nndflavomaculatus, 

 Fabr., Reut., but now, in reading the descriptions of the British 

 authors, I find that fulvipes, Saund. (= flavomacidatus, Dougl. and 

 Scott) cannot be referred to fidvipes, Reut. Messrs. Douglas and 

 Scott say (Brit. Hem., p. 365) : "Corium: * * disc with a large 

 pale yellowish-white triangular patch," while the $ oi fidvipes, Keut., 

 has only an external, mostly very small, and often scarcely distinct, 

 white spot. Examining the descriptions, and also the figures, drawn 

 and coloured by Fieber, I find also that there really exist three very 

 closely allied species in Europe. 



1. GrL. selectus, Fieb. {=jlavomaculatus, Fall., F. Sahib., Reut.). Vertex of 



J, as far as to the margin, convex; the margin in the middle carinate, carina 



arcuate* the front very convex. Head of ? very globose, vertex emarginate, seen 



from the side, very convex, and highly raised above the eyes. Last two joints of 



antenna? paler. Eyes of $ and ? remote from thepronotum. Pronotum at the base 



about two and a-half (6*), or almost two-thirds broader than at the extreme apex 



before the calli ; the calli in $ very elevated. Corium, behind the base, with a large 



triangular whitish patch, which, at the apex, is emarginate. The right forceps at the 



apex incurved, not, or scarcely, to the right, but to the left, almost at a right angle, 



and much prolonged ; the prolongation with the margins almost parallel, the upper 



margin near the apex with small teeth. 



* The carina rarely reaches almost to the inner margin of the eye ; but in this case the species 

 is also distinguished by the convex vertex, and by the eyes being remote from the pronotum ; 

 lastly, by the different structure of the right forceps. It is possible that the British specimens 

 (described as fiavomaculatut, by Douglas and Scott) are to be referred only to this variety, and not 

 to the following species.— O. M. R.
