NEW BRITISH SPECIES, ETC., IN 1866. 61 



Allied to H. pagana, but distinctly smaller, darker, and 

 with the abdomen more sparingly punctured. 



In the male the penultimate segment of the abdomen is 

 roughened with elevated points on the upper surface, and has 

 a tooth-like granulation on each side. 



13. HoMALOTA suBTiLissiMA, Kraatz, Stett. Ent. Zeit. 



XV, 126; Ins. Deutschl. ii, 230, 31; D. Sharp, 

 Proc, Ent. Soc. 19 Nov. 1866. 

 Mr. Sharp has found this species in several Scotch 

 localities, among clean sand on the banks of rivers and 

 lochs. 



It has very much the facies of a small Thinohius ; and 

 from its very small size (f lin.), linear, sub-depressed shape, 

 yellowish colour and slender antennae, can be readily sepa- 

 rated from our recorded species of Homalota. 



14. Homalota fallens, (Ferrari) Redt., Faun. Austr. 131, 



48; Kraatz, Ins. Deutschl. ii, 261, 67; D. Sharp, 

 Proc. Ent. Soc. 19 Nov. 1866. 



Mr. Sharp records the capture by himself of three or four 

 specimens of this insect on the banks of the Avon, near 

 Falkirk. 



It is closely allied to H. exiUs, but distinctly smaller than 

 that species, uniformly rufo-testaceous (with the exception 

 of the fourth and fifth segments, which have a pitchy tinge), 

 moderately shining, and with the elytra shorter, being 

 scarcely as long as the thorax. 



This insect appears to be of excessive rarity ; only one 

 specimen being known to Redtenbacher and Kraatz.

1 (?); G. R. Crotch, Cat. Brit. Col. ed. 2. 

 This species appears to be larger and flatter than P. pu-
