72 STAPHYLiNiDiE. [Ilomalota. 



cannot be classed with Group 1, as the male has no tubercle on the sixth 

 abdominal segment. 



Group 2. 



The species belonging to this group are distinguished from the 

 preceding by their smaller size, by having the sixth segment of the hind 

 body punctured as well as the others, and to a certain extent by the fact 

 that their antennae are not at all thickened towards apex. 



K. eximia, Sharp (Thincecia merifa, Muls. et Key). Linear and 

 depressed, very finely and thickly pubescent, fuscous or pitchy brown, 

 dull, very finely and densely punctured ; antennce, mouth, legs, and apex 

 of hind body clear testaceous ; head scarcely narrower than thorax ; 

 antennae slender and elongate, each joint very distinctly longer than 

 broad, third joint a little .shorter than second, fifth plainly longer than 

 fourth, 5-11 differing only slightly in length and breadth; thorn x a 

 little narrower than elytra, scarcely as long as broad, very slightly 

 narrowed behind, with a very distinct central channel, elytra considerably 

 longer than thorax ; hind body not so densely punctured as thorax and 

 elytra ; legs testaceous, tarsi rather short and stout. L. 2 mm. 



Male with the ventral plate of seventh segment of hind body very 

 much produced, very broad, and truncate, and plainly visible from 

 above. 



Very rare; Snowdon (Brewer) ; Toubridge (Horner), six specimens 188 i; Bewdley 

 Forest, Woreesttrsliire (Ehitch), 188G ; Scothind, Solw;iy, Tweed, and Forth districts 

 (Peebles, banks of Nitli, and of Almond near Ediuburgli). 



K. frag-ilis, Kr. (TJrhioecia frac/llis, Muls. et Eey, Ili/drosm.ecta 

 fragilis, Tlioms.). Eather closely allied to the preceding, but darker 

 in colour, Avith the antennae much shorter and the joints shorter in 

 proportion ; the eleventh joint instead of being equal to the tenth is half 

 as long again ; the head is somewhat narrower behind the eyes, and the 

 thorax is not so distinctly channelled ; in the male the under plate of the 

 seventh segment of hind body is rounded and not truncate, and in the 

 female it is gently emarginate in the middle ; sometimes the thorax has 

 a broad longitudinal depression in middle instead of a channel. L. 2 mm. 



Apparently not found except in Scotland, but stated by Dr. Sharp to be " very 

 abundant on the banks of rivers and streams everywhere" in that country. Ireland, 

 Bray., Co. VVicklow (Champion). 



ZI. long-ula, Heer. {thinohioides, Kr. ?, Thinoecia tliinohioides, Muls. 

 et Eey, = T. callida, Muls. et Eey, Hydrosmecta longula, Thoms.), 

 Yery like //. fragilis, but differs by having the abdomen much more 

 densely and finely punctured, and by its darker colour ; head a little 

 narrower than thorax, almost square, thickly and very finely punctured; 

 antennae pitchy with all the joints longer than broad, second joint longer 

 than third, third longer than fourth, 5-10 nearly equal, eleventh slightly 

 lon^'er than tenth ; in //. fragilis joints two and three are about equal, 

 ancl the eleventh is much more evidently longer than tenth ; thorax
