lOi 8TArHYLixiD.E. [Homalota. 



verse, 6-10 distinctly transverse, eleventh as long as the two preceding 

 together ; thorax nearly as broad as elytra, broader than long, with sides 

 rounded in front and nearly straight behind, rather closely and distinctly 

 punctured, and, together with elytra, clothed with rather thick yellowish 

 pubescence ; elytra plainly longer than thorax, distinctly punctured ; 

 hind body shining, segments 2-4 sparingly punctured, fifth more so, . 

 sixth nearly impunctate ; legs yellow or reddish yellow. L. 4-4| mm. 



Male with a raised longitudinal line nearly parallel to sutnre on each 

 elytron, and with two raised lines converging behind on the upper surface 

 of sixth segment of hind body ; female with the posterior margin of lower 

 surface of seventh segment excised in middle. 



Rare, but lias occurred singly or very spai'iugly iu many localities ; in moss, dead 

 leaves, and other situations; also by sweeping; Greenliitlie, Cliatluim, St. Mary Cray, 

 Dareuth Wood, Eslier, Asbtead, Caterhaui, Shirley, Cobham, Coombe Wood, Hamp- 

 stead ; Wimbledon Couimon (by beating willows); Highgate (on fences); in London 

 (birds' nests); Studley, Ripon, Yorkshire (by sweeping buiebells). 



H. exarata, Sharp. This species is certainly allied to the preceding, 

 and, like it, the male has the raised fold on each elytron, but it appears to 

 be distinct by its much smaller and narrower form, shorter and more slender 

 antennae, and shorter thorax ; the elytra also are more coarsely sculp- 

 tured ; the appearance of the two insects is entirely different, one being 

 largo, broad, and robust, and the other slender and linear. L. 3^ mm. 



Very rare; in nests of Formica fuUginosa, Tilgate Forest (Power and Brewer); 

 The Holt, Farnhani (Power). 



__ Group 14. 



The species belonging to this group are in general appearance much 

 allied to those of Group 5 {H, luridipennis, &c.), but differ by their 

 more transverse thorax, shape of antennae, and other points of structure ; 

 they seem, however, in their present position to be rather too widely 

 separated from that group. 



K. aquatica, Thorns, [suhfevea, Sharp, Afhda aqnatica, Thorns.). 

 Black Avith the elytra chestnut brown or fuscous brown, anterior parts 

 dull, hind body shining ; head narrower than thorax, slightly brassy, 

 finely and indistinctly punctured ; antennae rather long and slender, 

 and scarcely thickened toAvards apex, black Avith reddish or yelloAvish- 

 red base, joints 2-3 rather shnder, of about equal length, fourth shorter 

 than fifth, 5-10 each a little longer tluin broad, and each a little 

 narroAved toAvards base, eleventh shorter than the tAvo preceding to- 

 gether ; thorax black, often Avith a rather distinct brassy reflection, 

 broader than long, very finely punctured, Avith a broad impression in 

 middle of base ; elytra transverse, longer than thorax, distinctly punc- 

 tured ; hind body Avith segments 2-4 diffusely but distinctly punctured, 

 5-6 impunctate or nearly so ; leg.^ testaceous or dirty testaceous. L.
