2G2 CLAVICORNIA. [Tjx^. 



Llack ; each elytron with two orange-red spots, tlie one at base irregular, 

 the other behind middle simple, round or nearly round • punctuation 

 diffuse, closer on thorax than on elytra ; elytra with traces of strise ; 

 apex of elytra rounded in males, produced at suture in females; antennce 

 pitchy, club darker, narrower than in the preceding species and not quite 

 so compact ; legs pitch-black, with tarsi lighter ; size very variable. 

 L. 3-6^ mm. 



Under bark and at sap of firs and other trees ; common in Scotland under bark of 

 Scotch fir both Lowlands and Highlands, Solway, Clyde, Tweed, Tay, Dee, and 

 Moray districts, and probably general. Northumberland district, not rare ; it is 

 apparently very rare further south, but has been recorded, perhaps in some cases in 

 error, from Leicester, Hertford, Windsor, Dover, Hastings, Devon, &c.

This genns has been separated from fy$ on the ground that the 

 anterior coxal cavities ore narrowly closed behind and not open ; it also 

 differs in its narrow cylindrical form ; three European species are con- 

 tained in the genus, of which one is found in Britain. 



The larva, of P. ferruffineus is described and figured by Ferris, Ann. Fr., 1853, 

 p. 596, pL 18, fig. 77 — 83; it is 8-9 ram. in length, linear and rather depressed, 

 with the head rather large, almost subquadrate, nearly as broad as thorax ; the pre- 

 vailing colour is whitish with the thorax sometimes reddish, and the last abdouiinal 

 s-egmeut is ferruginous; the abdomen terminates in two short corneous cerci and a 

 very small anal appendage : this larva is parasitic on llylesinus, Hulustes, and 

 Et/Iohius ; the perfect insect lays its eggs in the borings made by these beetles, and 

 tlie larva when hatched apparently feeds upon the larvao of its hosts ; the pupa is 

 white, with a few hairs ou vertex, and sides of thorax and abdomen. 



P. ferrug-ineus, F. Elongate, convex, cylindrical, as a rule entirely 

 ferrnginous, with head darker, but occasionally the apex of elytra is 

 tlark ; head very thickly and rather strongly punctured ; thorax longer 

 than broad, very slightly narrowed behind, thickly and strongly 

 punctured; elytra moderately thickly punctured, more closely at 

 apex, with punctures almost arranged in rows ; apices truncate, Avitli 

 outer angles rounded ; legs rather stout, with tibiae dilated towards apex. 

 L. 4-5 mm. 



Under bark and at sap of freshly cut firs ; very local; Shirley, Eshei", Weybridge, 

 Woking; New Forest; Bournemouth, plentiful (Kemp- Welch); Northumberland 

 aiid Durham district, common ; Scotla,ud, under bark of Scotch fir, uot uncommon, 

 (Solway, Tweed, Tay, Dee, and Moray districts; it most probably occurs in many in- 

 tervening districts, but 1 know of no Midland records for the species, 



RHIZOPHAGINA. 



The position of this tribe is one of considerable difficulty, and it is 

 almost certain that it will eventually have to be raised to the position of 

 a family ; perhaps a further study of the exotic alHed genera and 

 species (of which several yet remain undescribed) is necessary before this
