I have also seen specimens of this form in the British Museum and in 

 the collection of Commander Walker. It occurs sparingly in various 

 parts of Kent (Sittingbourne, Sheppey, and Chatham) in company 

 with the true B. rufimanus, from which it differs in the greyer and 

 more uniformly coloured vestiture of the elytra. The true B. affinis 

 (which I have taken in Corsica) probably has no claim to a place on 

 the British list ; it has two almost bare black spots on the pygidium 

 as in B.pisi, L., as noted by Boheman. 



Ceu/J/orrJtynchidius chevrolati, Bris. in litt. — The name O. barne- 

 villei, Gren. (1866), should be used for this species, that of Brisout 

 being simply a '' nonien nudum.' 1 '' 



Ceutlwrrliynclius chalybceus, Germ. — Continental authorities are 

 unable, I believe, to recognise C. cliaiyh&us with any certainty, but as 

 Germar expressly states that the femora are " unarmed," it is evident 

 that the species known under this name in British collections has been 

 incorrectly identified. Our insect is, in fact, the C. timidus of Weise 

 (Deutsche ent. Zeitschr., 1SS3, p. 325), originally described from 

 Eastern Europe, but now known to be much more widely distributed. 

 I have taken it in abundance on Sisymbrium officinale at Plumstead, 

 Dartford, and elsewhere. 



Ceuthorrhynclms viridipennis, Bris. ? — This insect is mentioned 

 (partly on my authority), but not described, in Canon Fowler's 

 " British Coleoptera." It is the C. moguntiacus of Schultze (Deutsche 

 ent. Zeitschr., 1895, p. 420), a species common on crucifers, especially 

 BipJotaxis tenuifblia, in various parts of Germany. I have taken odd 

 specimens of it on several occasions at Caterham, Mickleham, and 

 Guildford, but never could be sure as to its food-plant, and Dr. Sharp 

 gave me an example of it many years ago under the name C. viridi- 

 pennis, Bris. These individuals are smaller, narrower, and less shining 

 than C. timidus, Weise, and they have the head and prothorax a little 

 less coarsely and more densely punctured, and (when the insect is in 

 fresh condition) more pubescent. C. moguntiacus and C. timidus may, 

 nevertheless, prove to be forms of one species, when a long series 

 of each can be compared, and though both attack Crucifera?, it is 

 hardly likely, to judge from my own experience, that their actual 

 food-plant is the same. I am indebted to the late A. Schultze and to 

 Dr. Karl Daniel for their assistance in determining these two insects. 



Poophagus nasturtii, Germ. — All recent continental authors, 

 including Heyden, Rcitter, and Weise (1S91), refer this species to 

 Geutdi orrhyn cli us.
