tained, but it is the Rh. Alliaria of Gyl. and Payk .*, and the R. 

 megacejihalus of Schonherr." The R. interpunctatus of Wilkin's 

 cabinet (now in the Zoological Society's museum) I have care- 

 fully examined. 



I found this species very plentiful in Swanscombe Wood near 

 Gravesend^ on the young shoots of the oak underwood of two or 

 three years' growth, in May.

Of this insect I am only acquainted with one example ; it is in 

 the National cabinet : with that specimen I have compared one, 

 with which it agrees, sent me by Dr. Gerniar bearing the same 

 name. 



It is found upon the white-thorn in Saxony.

Of the true Cure, mieovirens of Marsham I sent specimens to 

 Schonherr, who states the species to be synonymous ^\\x]l his R. 

 obscurus. 



I sent to Dr. Germar many specimens of No. 12, including 

 varieties, which he informed me were the R. obscurus of Schon- 

 herr.

* In the Linnajan cabinet I find an insect agreeing with Linnaeus 's de- 

 scription pinned to a label with the name All/aria' on the upper side, and 

 "4 violaceiis" on the underside, both in the handwriting of Linnaeus. This 

 insect is a?, and I have little doubt, judging from Gj'llenhal's description 

 is the T/iamtioph/liis frontalis of that author. Also besides the specimen 

 with the double name upon the label there is another label, upon which is 

 written by Linnaeus the name violaceus only ; the two insects upon this label 

 are <? ? of the same species as the single insect which stands on the double 

 name. In the ' Fauna Suecica,' p. 174, " No, 579, Cure, violaceus, medice 

 magnitiidinis." " No. 580, Cure. Alliariae, magnitudo pulicis, praecedenti 

 simillimus ; sed paullo major, an scxiis vel cstatis discrimenV 



Now it will be seen that Linnaeus, in his ' Syst. Nat.' 17G7, separates and 

 places in two distinct sections the C. AU'iarm and the C. violaceus ; the 

 lormer being placed in the section which he gives as character " longirostris 

 femoribus siniplicibus ;" the latter (C. violaceus) is located in the section 

 " longirostris femoribus dentatis." The fact is, that the C. violaceus and 

 C Miliaria; of Liimaeus are the sexes of one species, and in one sex (?) the 

 rostrum is longer, more curved and shining than in the male. Linnieus must 

 have overlooked the tooth in the femora, as he has done to my knowledge 

 in Ti/cki/ts, Brtichiis and some other genera.
