nearly of the same stature, they breed in wood, and inhabit 

 trees and flowers. 



* The thorax nearly cylindric. 



1. T. elongatus Linn. — Panz. 43. 16. — ruficollis Hilb. 

 Bluish black, with a red thorax. 



Found in June upon Oaks in Hampshire, and I once met 

 with it tolerably plentiful in sunflowers at Bungay in Suffolk. 



2. T. ambulans Fab. — ater Panz. 8. 9. — bimaculatus Don. 



Brit. Lis. V. 12.pl. ^ll.yi 2. var. 

 Entirely bluish black, and rather more slender than the 

 former species. 



Having once taken a pair of this insect in a garden in Suf- 

 folk, I consider it distinct, although Schonherr has included 

 it as a variety of T. elongatus. The insect figured by Mr. 

 Donovan is a singular and probably an immature variety, with 

 a testaceous spot on each side of the elytra. 



** Thorax somewhat obcordate. 



3. T. unifasciatus -Rossz. — Curt. Brit. Ent. pi. 26"! . 



This pretty and rare insect has several times been captured 

 at Windsor. I believe it inhabits Oaks in June ; it has also 

 been found on Oak posts, it is said, in Hertfordshire. For 

 the specimen figured I am indebted to my friend Richard 

 Latham, Esq. 



Specimens of Lathyrus Aphaca (Yellow Lathyrus) were 

 communicated by Professor Henslow and Mr. G. Charlwood.
