1895, p. 434), l)ut after exainiiiiug specimens kindly sent to nie l)y 

 l)r. Everts, who finds the insect commonly in grass fields on Taraxa- 

 ctim officinale and allied Compositae, I can only distinguish it from mar- 

 ginatus by the secondary sexual characters of the male ; I quite fail to 

 appreciate the difference in contour when seen from the side, which is 

 one of the main features of Schultze's diagnosis. Schultze records the 

 species from all parts of Germany, from Italy, Hungary, Turkey, and 

 East Russia. I have not hitherto seen British examples. 



C. punctiger, G-yll.— This species is in most cases distinguished 

 from the two preceding by the broadly ovate elytra, and sometimes by 

 having the thorax covered with non-confluent deep close circular punc- 

 tures ; the latter is the state described by Bedel, and the prevalent form 

 here at Colesborne, where I have met with the species very sparingly 

 since 1894. The puncturation of the thorax is not to be relied on as a 

 distinguishing character, because confluence of the punctures occurs 

 in varying degrees, though not so extensively as in marginatus and 

 simillimus. C. punctiger may, however, be easily known in either sex 

 by the very distinct groove on the pygidium. Mr. Champion sends 

 me specimens from the New Forest and Caterham. 



C. molleri, Thorns, (rotundahis, Bris.). — Of this very distinct 

 species Dr. Bengtsson has been good enough to lend me two males 

 from Thomson's collection, now in the University Musemn at Lund, 

 and these I have, by the courtesy of Mr. Hugh Scott, of the University 

 Museum of Zoology, Cambridge, been able to compare with the only 

 specimen marked Gevtliorrliyncliidius rotundatus, in Crotch's British 

 collection, and which is presumably referred to in Ent. Mo. Mag., viii, 

 p. 83, as taken by Crotch near London, and confirmed by M. Brisout ; 

 there are also four examples, from Caterham and Eeigate, in coll. 

 Champion, and Dr. Sharp tells me that he has one. This species has 

 the elytra broadly ovate, as in punctiger, but the interstices are 

 evidently narrower in proportion to the striae, and the colour of the 

 hair-scales is, normally, quite distinctive. Brisout, however, says of 

 the hair- scales " cendrees ou d'un cendre-brunatre " ; I have not seen 

 any British specimens of this latter form, but an example sent by Dr. 

 Everts clearly belongs to it. C. m'ulleri has the tuberculation of the 

 sides and apex of the elytra less evident than in the other species, but 

 it is nevertheless present.
