on the alternate interstices whu h are some- 

 what convex ; anterior tibiae with three teeth 

 at apex T. ALTEEXAKS, Gyll. 



T. myrmecophilus, Seidl. Pitchy black or brownish, with the 

 antennae and legs pitchy or pitchy ferruginous, very dull ; head with a 

 central furrow, antennae very stout ; thorax with sides rounded and 

 narrowed in front, very closely sculptured, and with an exceedingly 

 obsolete central furrow ; elytra with well marked striae which are almost, 

 if not quite, irupunetate; apex of anterior tibiae almost simple. L. 

 2-3 mm. 



Extremely local ; found by Mr. Moncreaff near Southsea, and recorded by him as 

 at one time common at Lumps Pond, Southsea beach, at roots of grass and in sand 

 holes, but the locality has been destroyed ; Hastings district (Bennett and Ford); 

 Mr. Gorham records it doubtfully from Freshwater, Isle of Wieht ; according to 

 Uedel it occurs under stones in May, and its name would seem to imply that it has 

 been found in company with ants ; it has been fouud in France and at the E>cuiial 

 in Spain. 



The species is intermediate between T. aristatus and T. squamulatus, 

 resembling more particularly the latter, from which it may be known by 

 its stouter and more evident elytral setae, its larger eyes, laterally more 

 rounded and bristly thorax, rather longer second abdominal segment, 

 and less horizontal scrobes, which are directed at first rather upwards 

 and then down towards the eye, and have their upper margin not 

 so sharply defined. 



T. aristatus, Gyll. Pitchy-rufous, with the head and thorax often 

 darker and the elytra lighter, the latter with comparatively close and 

 very distinct erect white scale-like setae ; scape of antennae stout ; head 

 furrowed ; thorax with the sides dilated and obtusely angled in middle, 

 very closely, but distinctly, sculptured, and with a very distinct central 

 furrow ; elytra subglobose, or globose-ovate, slightly rostrate and in- 

 flexed at apex, with strong deeply and coarsely punctured striae, inter- 

 stices finely rugose; anterior tibiaa almost simple at apex. L. 2^-3 nim. 



Sandy and chalky places; in moss and at the roots of Lotus corniculatus ; not 

 common ; Hampstead. ilickleham, Shirley, Favershani, Coombe and Birch Woods, 

 Mersthaiu (Surrey) ; Xew Forest ; PortsdowE, near Southsea, on chalk ; Scotland, 

 very local, Solway district. 



The castaneous or rather bright rufo-piceous elytra, strongly punctured 

 striae, and very stout white erect setae, together with the shape and 

 sculpture of the thorax, will easily distinguish this species. 



T. squamulatus, 01. This species is allied to the two preceding; 

 from the former it differs as above described, and from the latter it may 

 be known by having the sides of the thorax rounded and not obtusely 

 angled, the erect setae of the elytra relatively finer and the second ventral 

 segment equal to, and not less than, the third and fourth united ; the
