districts, but apparently rarer further north ; not recordid from the Northumberland 

 district; Scotland, local, Forth, Tay, and Moray districts. 



This species is easily distinguished by its parallel form, shining appear- 

 ance, and short, yellowish antennae ; it somewhat resembles Homalota 

 analis in shape, but besides other things, the form of the head will at 

 once separate it. 



O. amoena, Fairm. [favicornis, Kr.). This species closely resembles 

 the preceding, but it is as a rule a little less black and shining, and rather 

 broader ; the antennae are slightly shorter and of a lighter colour ; the 

 elytra are a little longer and rather more finely punctured ; the hind 

 body is not quite so parallel -sided, and is more uniformly punctured ; 

 the pubescence is finer and closer ; the elytra are said to be always 

 reddish or castaneous, but in many of the Scotch examples they are 

 quite dark. L. 2j mm. 



Apparently very rare, but most probably overlooked, as it is extremely hard to dis- 

 tinguish it from 0. hamorrhoa, except by very close comparison ; Eltham, Kent. 

 Scotland, rare, Forth district (Braid Hills, &c.). 



A, Waterhousei, Rye {nigrofvsca, Wat. nee Steph.). This species 

 appears to be generally considered by continental authorities to be 

 synonymous with the preceding ; it is, however, distinctly smaller, and 

 much duller, and differs in the sculpture of the elytra, which is as fine 

 or almost finer than in 0. amcena, but is slightly more distinct ; the 

 elytra also are more strongly sinuate near the postero-external angles ; 

 the only specimens I have seen are of an entirely dull reddish brown 

 colour, with the head and a greater or less part of the central portion of 

 hind body darker : the species appears to be more distinct than several 

 of those which are generally received, but the differences are hard to 

 express in words. L. vix 2 mm. 



Under large stones, lying among tidal refuse; also in haystack refuse, &c. ; 

 Sheerness (J.J.Walker); Hampstead (Waterhouse); Sydenham (Gorham); West 

 Ham. 



Section VII. (Sub-Gen. Bessopora, Thorns.) 



This section contains five species, 0. soror, 2^ciUiduIa, hrachyptera, 

 tarda, and misella ; they are well marked by having the elytra plainly 

 shorter than the thorax ; the hind body is sub[iarallel ; the antennae 

 are short Avilh the exception of those of 0. soror, which species, except 

 as regards the length of the elytra, bears a stronger relation to one or 

 two of the other sections : this latter species and 0. jJCiUiduIa are of a 

 lighter or darker testaceous colour ; the other three species are more or 

 less pitchy or dark ferruginous. 



O. soror, Thorns. (Java, Kr. 1). Entirely testaceous with the hind 

 body darker before apex, finely punctured, and pubescent ; head and 

 antennae testaceous, the former with the eyes alone black, antennae rather 

 long, thickened towards apex, third joint plainly shorter than second,
