NEW BRITISH SPECIES, ETC., IN 1865. 105 



73. Ceuthorhynchus punctiger, (Megerle) Gyll. in 



Schon. Syn. Ins. iv. part i. 346, 92. 



Mr. Crotch states that this insect is again separated from 

 C. ■marginatus; WaUon and Thomson, however, having 

 united them purposely. 



Gyllenhal (Ins. Suec. iv. 593, 130) originally considered 

 punctifjer as a variety of the species ; applying to it the names 

 7)117107' and ■pygmcea. 



From Schonherr {loc. cit.) it appears to be very like 

 C. marginatus, but generally two sizes smaller, or even more; 

 with the sides of the thorax bearing a small (often obsolete) 

 tubercle, and the apex of the pygidium incised, instead of 

 rotundate and entire. 



I possess a very small insect, taken in company with, and 

 exactly resembling, C. marginatus, in which there are but 

 .sio? joints to the funiculus of the antennee. 



74. Ceuthorhynchus versicolor, Ch. Brisout, MSS. 

 Mr. Crotch states that his specimens purporting to be 



C. quei'cicola are referred by M. Brisout to this unpublished 

 species ; and that very possibly we have the true quei'cicola, 

 Fab., also. 



De Marseul, — although rightly eliminating, as Cevtlior- 

 hynchideiy certain species hitherto always considered pro- 

 perly located in CeutJio7'hy7ichus,— '&i\\\ retains quei'cicola, 

 Fab., in the latter genus. My specimens representing that 

 species, — most probably identical with Mr. Crotch's, as they 

 agree with the ordinary quei'cicola of British collections, — 

 are, however, to be referred to Ceuthoi-hynchide^is, having 

 only six joints to the funiculus. I see that in this (as, indeed, 

 in every other) respect they agree with the quercicola of 

 Thomson, who considers his insect to be the Fabrician 

 species of that name.
