tubercles on each side of the thorax, which entirely fails 

 the marginatus. 



From C ragusae Bris {piierulus Schultze) it differs in 

 the somewhat deeper punctuation of the thorax, in larger 

 size, in having the thorax somewhat narrower than elytra 

 (in ragusae it is almost as broad as elytra) and in the 

 shape of the elytra which are tapering from the shoulders 

 or a point just behind the shoulders (by ragusae they 

 are not tapering until a little before apex). 



From incisus Schultze it may be distinguished by the 

 absence of white hairs on the sides of thorax and by 

 the tubercles on thorax being more distinct. 



From C. simillimus Edwards (Entom. Monthly Mag. 

 Sec. Ser. vol XXII pag. 210) it may be distinguished by 

 the white spots of hairs on elytra which Mr. Edwards 

 tells me are totally absent in simillinuis. Also this species 

 is said to be of quite the same shape as marginatus, 

 while my species as above described differs from it on 

 several points. 



Of this species specimens have been found with 6 

 joints in the funiculus of antennae in stead of 7 as also 

 specimens with 6 joints in the one and 7 in the other 

 funiculus (quite as is the case in marginatus). 



The species is found in Denmark on Papilionaceae 

 and it seems — as far as it has been possible to ascer- 

 tain — especially to be attached to Lotus corniculatus. 

 The allied species at least marginatus, are leading on 

 Borraginaceae and I have upon the whole never before 

 heard of any species of the genus Ceuthorrynchus feeding 

 on Papilionaceae. It may be added that 1 have seen the 

 species in Thomsons collection in Lund, mixed with the 

 common C punctiger Gyll. 



The type is in my collection.
