353 Mr. Toulmin Smith on the Classification 



was by far the most abundant coleopterous insect I met with. 

 It is not at all gregarious, but single individuals are seen resting 

 on the leaves of trees that overhang the sides of the roads; 

 scarcely a shrub being without several for miles together. 



98. Elaphidion spinicorne. From the creaking sound made 

 by this species in common with many others of the Longicornes, 

 it is commonly known by the name of the Fiddler. It is one of 

 those species whose activity is not confined to any particular sea- 

 son or locality, but is a common visitor at all times, flying in at 

 open windows, and crawling around the candle- shades, or up the 

 walls, in the evening. The spinous processes of the antennae and 

 of other parts are so long and sharp that they pierce the fingers 

 when the insect is handled, though ever so tenderly. 



99. Elaphidion 6-fasciatum. Very common on the leaves of 

 low trees by the sides of the Hampstead Road throughout June. 



100. Elaphidion bidens ? Rare : a specimen taken at the 

 Hampstead Road near the end of June. 



lOI to 104. Elaphidion (sp. neair insulare) . And three other 

 species ; occurring sparingly in June, on the Hampstead Road, 

 and occasionally flying in at the open window at Content, in the 

 evening. 



105. Callichroma virens. Of this magnificent insect, which I 

 have taken also in Alabama (U.S.), two specimens occurred in 

 Jamaica, both of them much larger and finer than my American 

 specimen. The first was taken resting on a projecting twig of a 

 tree overhanging the Hampstead Road, June 24th, pretty high 

 up. The other was brought me from the woods behind Blue- 

 fields, on the 1 8th July. Both were strongly fragrant during 

 life.

 By J. Toulmin Smith, Esq. 



Genus Brachiolites. 



Character. Shape and size very various, but always much lobated 

 or branched : internal cavities of lobes and branches always 

 communicating : extremities closed or open : membrane form- 

 ing the wall sometimes plain sometimes folded : margin of wall 

 thinned or rounded off to an edge : membrane of wall poly- 

 piferous on both external and internal surfaces. 

 Departing altogether from the forms hitherto examined, the 



present genus is characterized by its lobated or branched divi-
