British Species of Homalota. 243 



ones, the sixth segment shining, and very sparingly punc- 

 tured ; the sides are rather sparingly furnished with out- 

 standing setge, the apex more distinctly. The legs are 

 bright yellow, the middle tibiae with a short indistinct 

 outstanding seta about the middle, the hinder ones with- 

 out any exserted seta. 



The male has the ventral plate of the seventh abdomi- 

 nal segment narrower and longer than the female. 



This species occurs sparingly in various parts of Scot- 

 land; Rannoch, Thornhill, Strath Cannich; also, but very 

 rarely, in the neighbourhood of London.

A very distinct species ; the much developed, long an- 

 tennas, the yellowish elytra, the much pointed and thickly 

 punctured abdomen, and the very long exserted setae of 

 the tibiae are quite sufficient to distinguish it. The an- 

 tennae are long and stout, not thickened after the seventh 

 joint, nearly black, with the first joint pitchy, the 

 basal joints with distinct exserted hairs ; joint three con- 

 siderably longer than two, four much smaller than any of 

 the others, its length distinctly less than its breadth, 

 from five to ten each joint is distinctly longer than its 

 predecessor, the fifth not quite so long as broad, the tenth 

 longer than broad ; eleventh joint long, obtusely pointed, 

 quite half as long again as the tenth. The head is com- 

 paratively small, considerably narrower than the thorax, 

 black and shining, sparingly and finely punctured, but 

 with the pubescence distinct. The thoi^ax is scai-cely 

 narrower than the elytra, its breadth about half as great
