more turned towards the front of the insect than in other species. 

 Many of" tlie species Iiave four callosities on the surface of the thr)rax, 

 but these are not always visible, and it is better not to rely on this 

 character. The eye facets of this section appear to me usually lart^er 

 than those of the other, so that character is not so satisfactory for 

 G. cellaris as it is for C. acutangidns. 



I do not feel sure whether C. punctipennis is really distinct from 

 C. pilosus. ]t is, in my experience, the commoner insect of the two, 

 but I may draw the line of distinction at the wrong place. In the 

 British Museum there is a specimen in which the punctures are not 

 oidy far a|)art, but also much larj^er. li punctipennis ought to have 

 the punctures larger as well as further apart, my insects and most of 

 those standing in British collections as punctipennis are really pilosus. 

 In C. setuJosus the joints of the club of the antennae are more widely 

 separated than in the other species, and the elytra are shorter and 

 the pubescence is very rough. C. schmidti and rujicornis, on the other 

 hand, are very distinct. I have no British representative of the 

 former. C. rujicornis I have from a faggot heap on the hill above 

 Streatley, Berks. ; the specimen in Stephens' collection (presumably 

 the type) is pale coloured. The species is not included in the last 

 European Catalogue except as a possible synonym of li/coperdi, which 

 is absurd ; it is only mentioned by Ganglbauer in a note, in which he 

 says that Stephens' name is not a synonym of timhratus, but that the 

 insect referred to appears to be more like lycoperdi, in which he is 

 right, as it undoubtedly belongs to the group with outstanding 

 hairs ; but there is a great difference between being " more like " and 

 being synonymous with. It has a sharp tooth behind the callosities 

 of the thorax. I know of no other European species to which it can 

 ])ossibly be referred. In connection with the above article, I have 

 jiarticularly to thank Mr. G. C. Champion for valuable suggestions 

 and help, Mr. Newbery for kindly checking most of the table with 

 me with actual specimens, Mr. E. Saunders for going through his 

 collection with me and for the loan of specimens, and Mr. Arrow, of 

 the British Museum, for obtaining for me Kraatz's types, without 

 which I should have fallen into error, and for comparing s[)ecimens 

 for me.
