base and finely at the apex. The under-side is covered with ashy 
pubescence, the abdomen being more or less red towards the tip. L. 
15-17 mm. 
A single male was taken by Mr. Thorncroft at Holme Bush, Sussex, in the 
summer of 1865; the species is found rarely in the south of France, Spain, Turkey, 
and Greece, so that in all probability this specimen can hardly be considered 
indigenous, as no other specimen has occurred either before or since, and it might 
have been imported in timber.) 
STRANGALTA, Serville. 
According to the Munich catalogue and M. Lameere’s supplement the 
genus Strangalia proper only contains fourteen species, of which one 
only (S. attenwata) is found in Europe, the rest being described from 
North America, Northern Asia, and Persia; a large number of species, 
however which have been included under Strangalia are placed under 
Leptura by Gemminger and Von Harold, Thomson, Reitter, and others; 
of these eighteen inhabit Europe, of which six occur in Britain; they 
are found like other members of the tribe on Umbellifere and other 
flowers; the larve occur in decaying wood of various trees; that of 
S. armata is described by Westwood (Classification, i. p. 369); it is 
subparallel, with the head nearly as broad as the prothorax, which, 
together with the head, is depressed and scaly ; the posterior margin of 
the thorax is furnished with a transverse series of short recurved spines, 
and the same is the case with the abdominal segments of the pupa; the 
extremity also of the abdomen is terminated by two acute points bent 
upwards. 
The species much resemble those belonging to the genus Leptura 
proper, but may easily be distinguished by having the posterior angles of 
the thorax produced in a spine ; from Grammoptera they may be known 
by having the elytra distinctly narrowed to apex. 
I. Thorax narrowly or very narrowly and suddenly con- 
stricted just before apex; elytra with the humeral 
tubercle situated on the base.
