Only found on the banks of tlie Nith and its tributary Cuiru Water by Dr. Sbarp, 

 uudtT stones, in coinpauy with Scopmus Erichsoni. 



H. soror, Kr. {furcijjafa, Muls. et Rey, Amischa soror, Muls. et 

 Eey). This species very closely resembles H. analls v. major in colour 

 and general appearance, but is distinguished by its more thickly and dis- 

 tinctly punctured hind body, and especially by the sexual characters; in 

 the male the head is more or less distinctly channelled ; the seventh 

 dorsal segment has a larger notch, commencing on each side near the 

 outside angle of the upper plate ; the ventral plate" is very much produced, 

 and furnished at apex with five or six distinct black hairs in middle. 

 L. 2 mm. 



Mar.^by pbices ; rare; Lee and Tonbridge, Kent ; Barnes, Micklebam, Weybridge, 

 Egbam and Walton, Surrey ; not hitherto recorded except from the London district. 



Group 12. 



This group contains five very small species, all less than 2 mm. in 

 length ; they are easily distinguished by their stout or very stout 

 antennae, and the impxinctate sixth segment of hind body. H. 2mralle7a 

 miuht perliaps be placed in a different group by reason of its different 

 habitat and appearance, and the differf ntly shaped antennae. 



XZ< ezilis, Er. ( paranfa, "Rev, parilis, Eey, Meofica exilis. Muls. et 

 Eey). A pale-coloured little species, pitchy-broAvn, dull, with thick 

 pubescence and extremely fine punctuation ; head large, as broad or 

 nearly as broad as thorax ; antennte short and stout, third joint not 

 nearly as long as second, 5-10 very distinctly transverse, tenth joint 

 tAvice as broad as long, eleventh large and broad, twice as long as 

 tenth ; thorax nearly as broad as elytra, sides nearly straight, a little 

 narrowed behind ; elytra a little longer than thorax, almost square ; hind 

 body with extremity testaceous, middle segments more or less pitchy, 

 basal segments often lighter, punctuation extremely fine, scarcely visible 

 towards apex; legs yelloAv. L. l|-lf mm. 



Male with the seventh dorsal segment of hind body truncate and 

 slightly sinuate, female with the same part slightly rounded ; the dif- 

 ferences, however, are very slight. 



Marsbv places, during early spring; very local; London district, generally; 

 Hythe ; Scarborough ; Worcester (sandy banks of Severn). Scotland, local, Low- 

 lands, Forth and Solway districts. 



A variety occurs in the London district ("Wimbledon, Esher, Lee, &c.) 

 which is rather darker and narrower, with rather shorter antennse, and 

 less transverse thorax ; this appears, in fact, to be much more common in 

 the London district than the type form ; the Scotch forms also vary in 

 (gome degree.
