than long, distinctly narrowed in front, with a double punctuation, 

 consisting of rather diffuse larger punctures and very fine smaller punc- 

 tures ; this latter character is only visible under a strong magnifying 

 power ; the base is sinuate, and the posterior angles are strongly pro- 

 j-cting; elytra moderately convex, gradually narrowed behind, obtusely 

 rounded at apex, with fine punctured striae, and with the interstices 

 very finely rugose and, besides, finely punctured ; legs ferruginous. L. 

 2|-3 mm. 



Male with the club of the antennae larger, longer than the funiculus; 

 female with the club smaller, shorter than the funiculus. 



By sweeping herbage; occasionally found on palings, in sandpits, &c.; local; 

 generally distributed nnd common in the London district ; Hastings ; Portsmouth 

 district; New Forest; Glanvilles Wootton ; Snowdon; Hertford ; Knowle; Bewdley ; 

 Cannock Chase ; Brainhall, Cheshire; Barton Moss ; Scarborough; Scotland, very 

 local, Solway, Clyde, and Forth districts ; Ireland, near Belfast : it is probable that 

 it is often passed over by ordinary collectors, as it gathers up its legs and looks much 

 like a seed in the net. 



T. carinifrons, Bonv. (elateroides, Eedt., nee Heer.). This species 

 so closely resembles the preceding that it was for many years mixed 

 with it in some collections ; it may, however, be distinguished by the 

 following characters: The forehead has the two frontal carinse more 

 distinct, and the eyes are divided by a narrow horny plate considerably 

 beyond the middle ; the thorax, in the male at least, is Hatter, and 

 much more contracted in front, and the elytra are more acuminate, with 

 the striae more delicately impressed, and the punctures on the interstices 

 more distinct, the surface being less coarsely rugose. L. 2^-3 mm. 



By sweeping in woods ; occasionally on palings ; rare, but probably overlooked ; 

 ChUlehurst (Matthews) ; Sheppey (Champion and Walker) ; Tonbridge (Wollaston, 

 and recently taken in numbers at the same place by A. C. Homer) ; Shirley, Esher, 

 Tilgatc, Forest Hill; New Forest; Southampton (Walker); Glanvilles Wootton j 

 according to Redtenbacher it is very common at Vienna on Parietaria officinalis. 



T. elateroides, Heer., nee Kedt. (gracilis, Woll.). This species 

 in general shape and structure is closely allied to T. carimfrons, from 

 which, however, it may at once be known by its very much smaller size, 

 as well as by the more finely sculptured elytra, of which the interstices 

 are more thickly punctured ; from T. dermestoides it may further be 

 known by having the eyes more divided, and the frontal carinae more 

 distinct and extended . further to base of head ; in size it resembles T. 

 (ibtu#u9> but is more elongate, with longer antennae, and may be known 

 by the presence of the frontal carinae. L. 2 mm. 



At roots of grass, and in moss, flood refuse, &c. ; often in salt marshes; usually 

 found in early spring; rare; Chatham (Brewer); Sheerness (Walker); Cowley 

 (Power) ; according to Kedtenbacher it is found on Parietaria officinalit. 



T. obtusuB, Curt, (pusillus, Heer.). The smallest of our species; 

 allied to the preceding, but shorter, with the elytra shorter and less
