THE LONGICORNES. 207 



and poles, etc. C. arietls is very abundant in flowers, 

 etc., about June. 



The Obriades have the thorax cylindrical, constricted 

 at the base; the antennae setaceous, never less than the 

 body in length ; the elytra entire and parallel, and the 

 femora clavate. 



Obrium cantharinum, a small, shining, entirely reddish 

 species, with large eyes, and very long antennae, is of 

 considerable rarity : Gracilia pygm&a, our other repre- 

 sentative, duller and darker, occurs not unfrequently on 

 old wood- work, twigs, etc. 



The LAMIAD^; are divided into two sub-families, La- 

 miades and Saperdides; in which the head is abruptly and 

 vertically bent down, the antennae are inserted within 

 the emargination of the eyes, the tibiae armed with small 

 spurs, and the legs not very elongate. 



In the Lamiades the femora are distinctly clavate, the 

 intermediate tibiae obliquely truncated, and with a se- 

 tose tubercle on the outer side behind the middle, the 

 thorax is armed with a lateral spine, and the mandibles 

 are short. 



In this sub-family some of our largest and most 

 curious Longicornes are found ; Lamia textor and Asti- 

 nomus aedilis being especially remarkable. The former 

 of these is a large, clumsy, convex, dull black insect, 

 found near Bristol, and at Rannoch in Perthshire, on 

 willow-trees and in osier beds, the top shoots of which 

 it is reported to weave together as a nidus. 



The other, A. adilis (Plate XIII, Fig. 4), is con- 

 spicuous for the enormous length of its antennae, espe- 

 cially in the male. This, also, occurs at Rannoch, where 

 it may be not uncommonly seen flying across the glades 

 of the Black Forest with its long appendages streaming
