Scoll/tUJt.] RHYNCHOPHORA. 409 



ceding, but is easily distinguished by the sculpture of the elytra, 

 which have the punctured striae much less strongly impressed and the 

 punctures of the interstices not much finer than those of the striae and 

 arranged in single rows ; it is also a little narrower ; the colour is 

 shining black with the elytra ferruginous, and the antennae and greater 

 part of the legs are red ; the thorax is very finely punctured on disc and 

 less finely but not very closely at sides, and the ventral segments of the 

 abdomen are simple in both sexes. L. 3|-4| mm. 



In decaying apple, apricot, pear, cherry and other fruit trees; Ratzebur? has 

 nlso found it in whitethorn and elua ; very local, but not uncommon where found ; 

 Peckliam ; Hammersmith (Stevens) ; Tonhridge (Homer) ; Southsea, on black- 

 thorn (Moncreaft'); Monmouthshire and Herefordshire, freely (Chapman); Lindow 

 and Urmston, Cheshire (Chappell); Strett'ord, near Manchester (Restou) ; Scar- 

 borough (Lawson). 



(S. carpini, Ratz. This species is very closely allied to the preceding, 

 but is smaller, and may be distinguished by having the punctuation of 

 the thorax stronger and closer at the sides, and the punctuation of the 

 stria? and the interstices equally strong, whereas in S. pruni the punc- 

 tuation of the interstices is a little finer ; the general punctuation of 

 the elytra is also less regular than in the last mentioned species. L. 

 3-3| mm. 



This species occurs in France, Germany and Austria, on the Horn- 

 beam (Carpinxs betulus), and has been introduced into one or two of our 

 collections, but I know of no authentic specimen, although it very prob- 

 ably occurs in Britain ; in fact, Mr. E. "W". Janson has seen workings in 

 Hornbeam which were almost certainly to be referred to it; the differ- 

 ences between the species and S. pruni are so very slight that the two 

 insects may very easily be confused.) 



S. intricatus, Ratz. Black, shining, elytra duller, with the 

 antennae and legs ferruginous, and the femora and elytra pitchy-brown 

 or pitchy-red, the latter with very close rows of punctures and extremely 

 narrow interstices, more or less rugose, with short erect yellow bristles 

 at sides and towards apex; underside with close grey pubescence; 

 thorax longer than broad very finely and rather closely punctured on 

 disc, more closely and sub-rugosely punctured at sides ; suture depressed 

 behind scutellum ; the colour is variable, the thorax occasionally being 

 reddish. L. 3-4 mm. 



Male with the forehead depressed and clothed with short thick fuscous 

 villose pubescence. 



Female with the forehead convex and somewhat strigose. 



In decaying oak ; not common ; Dareiith ; Chatham ; Forest Hill ; Dulwich ; 

 Hastings district ; New Forest ; Monmouthshire and Herefordshire rare (Chap- 

 man) ; Sherwood Forest; Dunham Park, Manchester; Northumberland and Dur- 

 ham district, rare, Little Benton. 



Si rug-ulosus, Eatz. The smallest of our species; black, shining,
