[In reference to Mr. Crawshay's note I should like to say that 

 great difficulty exists as to the species of Tetropium both in Britain 

 and on the continent. T am endeavouring to elucidate this, and should 

 like to be able to examine the specimens of the genus that may exist 

 in British collections. I have before me specimens of Tetropium taken 

 near Manchester in 1865, and I think I can say with a fair confidence 

 that we have two, if not three, species in England. Weise has just 

 described a T. gahrieli from Switzerland, Germany, &c. Mr. Craw- 

 shay's insect is either T. gahrieli, Weise, or a closely allied form. 

 If the second alternative prove to be correct I propose to call the 

 Leighton form T. crmoshayi. — D. Sharp.] 



[T. gnbrie!i,W ehe (Deutsche ent. Zeitschr., 1905, p. 13(5), from the 

 Lower Engadine (Tarasp), Tyrol, and Silesia, is said to differ from T. 

 fuscum, P., and T. liiridum, L. (= castaneum, L.), in having the frons 

 somewhat convex and not canaliculate. I have taken various speci- 

 mens of what I suppose to be T. fuscum in the Engadine (at Guarda, 

 near Tarasp) and on the Simplon ; some of these have the frons 

 canaliculate, and in others the groove is wanting. — G. C. C.] 



BARIS {LIMNOBARIS) T-ALBUM, Linn., and B. lULISTRIATA, Steph. 

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



J. Sahlberg [Acta Soc. Pro Pauna et Plora Pennica, xix, 3, pp. 

 22, 28 (1900)] separates Bitris T-alhum into two species, B. T-album, 

 L, and £. mnrfuJus, Sahib. These two forms occur in Britain, and 

 were described by Stephens [Mand., iv, p. 10 (1831)]. They may be 

 separated thus : — 



Larger and more elongate, the elytral interstices irregular! j uniseriate- punctate, 

 especially towards the suture, the punctures each bearing a rather long, 



coarse, decumbent, whitish hair pilistriata, Steph. 



(= T-album, Sahib., nee Linn.). 

 Smaller, more glabrous above, the prothorax a little more transverse, the elytral 

 interstices regularly uniseriate-pnnctate, the punctures each bearing a short, 



fine, decumbent, whitish hair T-album, Linn. 



(= atriplicis, Steph., martulus, Sahib.). 



I have seen B. pilistriata from various southern localities, 

 Sheppey, Paversham, Arundel, Woking, Wicken, &c., and B. T-alhum 

 from Bearstead, Snodland, Oxford, Scarborough, Aviemore, and 

 Nethy Bridge, the latter apparently being the most widely dis- 

 distributed (Stephens gives near London, Bristol and Suffolk for
