middle excepted ; elytra convex in both sexes, very coarsely and deeply punctate- 

 striate, the punctures closely placed and the striae deep to the apex, the 

 interstices more or less convex ; body distinctly pubescent, the elytral inter- 

 stices each with a regular series of decumbent hairs pyrencBus, Seidl. 



lu both species the anterior tibiae are incurved at the apex in the 



male, and straight in the female, and also emarginate on the inner 



side towards the tip. Dr. Seidiitz describes the rostrum as broader 



in B. piirencBiis, but this is due to its more parallel shape. From B. 



pelJucidiis, Schonh., apart from the more slender femora in the male, 



the present insect may be known by the shorter pubescence, this 



character also separating it from the European B. mollicomus, Ahr., 



the latter also having a more curved rostrum. I am indebted to Mr. 



Keys for living and dead specimens of B. pyrenceus for examination. 



M. Fauvel, too, has sent me an example from Caen ; he says it is to 



be found in woods throughout Calvados.

THE LEMA ERICRSONI, Sttffr., OF BRITISH COLLECTIONS : 

 SYNONYMICAL NOTE. 



BT G. C. CHAMPION, P. Z S. 



The insect standing under this name in British collections should 

 be referred to L. septenfrionis,W else {= ^richsoni, Thoms.,«ec SufEr.), 

 it agreeing much better with the description of the latter than with 

 that of L. Ericlisoni, Suffr. "We have two forms of it : — one, found 

 as yet only in Ireland, having the thorax pitchy-black ; the other, 

 found in the south of England, with the thorax metallic-green and the 

 elytra relatively a little broader. 



L. septentrionis is described by Weise (Naturg. Ins. Deutschl., vi, 

 p. 63) as being " more slender than L. Erichsoni, Suffr., and nearly as 

 elongate as L. melanopa, L. ; sky-blue, the thorax darker, nearly black, 

 the head generally greenish. The latter shaped as in L. Erichsoni, 

 but rather more distantly, strongly, and deeper punctured. The 

 thorax very similar to that of L. Erichsoni, but distinctly narrower 

 and deeply constricted before the base, the constriction rather re- 

 motely impressed with deep punctures of different sizes, but more 

 finely and evenly punctured at the sides, where the constriction is 

 more shallow ; the disc scarcely visibly and not closely punctured, very 

 shining, with large punctures nearly arranged in row^s towards the 

 anterior angles and in three longitudinal rows on the middle. The 

 elytra moderately shining, coarsely punctate-striate, the striae deep, 

 the interstices very narrow, partly touched by the punctures."
