cation of this superb tribe of insects, which now amounts to 

 about 600 species: of these 14 only have been found in En- 

 gland, several of which have been most probably imported in 

 timber ; and although this is a proof that the Buprestidae are 

 not attached to northern latitudes, yet it is remarkable that 

 twice as man}' are actually natives of Sweden, and Gyllenhal 

 has described 46 species in his Insecta Suecica, including 

 those that are supposed to have been introduced by intercourse 

 with foreign countries. 



Trachys is a singular little group of this family, readily re- 

 cognised by its short broad ovate figure, and although so dis- 

 similar to Aphanisticus (pi. 262.) it is evidently closely allied 

 to that ffenus. M. Solier not having been able to detect the 

 maxilla? and palpi of Trachys, I am happy in the opportunity 

 of adding figures of them. 



Three species of this circumscribed genus have been found 

 in the neighbourhood of London. 



1. nana Fab. — Paiiz. 95. 9. 



"Obscure black, somewhat aeneous, smooth; face excavated, 

 elytra triangular, with punctures somewhat in striae and a 

 lateral elevated line." Gyll. v. 1. 464. 3. 

 May and June, amongst underwood in Coomb Wood. 



2. minuta Linn. — Curt. Brit. Ent. pi. 686. 



May 13th on Sallows, Coomb Wood and Epping Forest, 

 J. C. ; end of May, a pair in Parley Copse, Mr. Dale ; June, 

 Clapham, Park Wood, Bedfordshire; July and August, Met- 

 ton and Monk's Woods; on birch and nut trees, Darent, 

 Norwood, &c. 



3. pygmaea Fab. — Do7i. v. 8. pi. 282. 



Head and thorax smooth, cupreous or aeneous, elytra blue 



or green, with lines of strong punctui*es. 



May, in a puddle of water in Coomb Wood, Mr. MacLeay, 

 and the late Mr. Joseph Hooker found one on Menyanthes 

 trifoliata (pi. 294.) at St. Faith's in Norfolk. It has also once 

 occurred in Cambridgeshire. 



The Plant is Bryonia dioica (Red-berried Bryony).
