260 THE ENTOMOLOGIST, 



general revision of the group. C. Troglodytes appears from 

 M. Brisout's account to be rather a magazine of species : 

 the very small form from our south coast, Folkestone, Isle of 

 Wight, Weymouth, &c., known in this country as pygmaeus, 

 Guyon, had been received by him from the Rev. J. F. Daw- 

 son : he therefore intends to describe it as C. Dawsoni. Two 

 other species which occur here will be described — C. fron- 

 talis, a small species, like C. Dawsoni ; and C. Chevro- 

 latii, at once known by its beautiful white variegated 

 markings. 



Among the true Ceuthorhynchi many changes must, unfor- 

 tunately, be made. C. inaffectatus = Rapae, GylL, Schh., 

 as Mr. Walton had previously suspected,, the true C. inaffec- 

 tatus being only C. Syrites, female. C. uliginosus has already 

 been disposed of by Mr. Waterhouse, but, as if to add to the 

 confusion, the Schonherrian type does not = Caeliodes di- 

 dymus, as does Mr. Walton's. C. Chrysanthemi = campes- 

 tris, Hbst. : from this species M. Brisout separates a smaller, 

 differently marked form as C. vicinus. C. melanostigma = 

 rugulosus, Hbst., which removes the confusion between this 

 and C. melanoslictus, Msh. C. inarginatus has a species 

 separated from it — C, punctiger, ScJiJi. (Mr. Walton, how- 

 ever, unites them purposely, as does also M. Thomson in 

 his recently published volume). C. quercicola = versicolor, 

 Bris. MSS.f as far as my specimens are concerned ; very 

 possibly we have the true quercicola, Fab., also. C. bigut- 

 latus = verrucatus, Sclih. C.inornatus I have already stated 

 to equal C. AUiariae, Bris., a name having the precedence by 

 about a year. In addition to these, I forwarded M. Brisout 

 specimens of the species in our lists under manuscript 

 names : these appear pretty generally to be known. C. im- 

 pressicollis, Little = angulosus. Germ., and is of very great 

 rarity there as here. C. Crux, Walt., is hitherto unde- 

 scribed : M. Brisout has provisionally named it C. Euphor- 

 bise. C. hispidulus, Siev. = pilosellus, Schh., a species from 

 Spain and S. France. Besides these there remains one species of 

 which I have one example from Gainsborough, taken by Mr. 

 Wollaston, and Dr. Power has also a specimen : this appears 

 to be the nigrolerniinatus, Woll. (Cat. Col. Mad. 1854), a de- 

 termination in which Mr. Wollaston himself agrees, remark- 

 ing only that it is a little less tessellated than the Madeiran
