" rapprocliees au sommet d'une lame angulaire plus prolongce que les 

 dents laterales." 



The suture of tlie elytra in the male is elevated into a distinct carina 

 terminating abruptly at scutellum ; a variety occui'S in which this 

 sutural carina, and also that on seventh segment of hind body are 

 wanting. 



At the exudino: frass of Cossus-infecteA trees; uot unc^ainwiou in the London 

 district, and the Southern and Midland counties; rarer further north; Manchester, 

 Dunham Park, not uncommon ; not recorded from the Nortliumberlaud district ; 

 Scotland, rare, Moray district only. 



T. hospita, Maerk. {castanea, Aube, amtmlis, Key. This 

 species closely resembles the preceding in colour, but is much 

 smaller, and has the hind body much more plainly punctured ; with 

 this exception the punctuation does not differ much, and the struc- 

 ture is much the same ; the antenupe are stoat, yellowish, third joint 

 longer than second, fourth about as stout as third, as long as broad, 

 5-10 each a little broader than the preceding, fifth slightly, 6-10 

 strongly, transverse ; thorax with an indistinct longitudinal channel ; 

 hind body with segments 2-4 evenly and pretty closely and finely 

 punctured, fifth more sparingly punctured, sixth impunctate, or nearly so ; 

 legs yellowish. L. 3| mm. 



Male with the seventh segment of hind body furnished with an obtuse 

 tubei*cle on its upper surface towards middle of base, apex produced in 

 middle, in the form of two teeth close to one another, hind margin also pro- 

 duced on either side in the form of two rather blunt teeth or projections. 



In Ijurrows of Cossns ligniperda like the preceding, often occurring in company 

 with it ; local ; Sheerness ; Sittingbnurne ; Shirley ; Caterham ; Dulvvich ; New 

 Forest ; Holecombe, Devon ; Dean Forest ; Repton ; Scarborough ; Manchester ; 

 not recorded from the northern counties or from Scotland. 



NOTOTHECTA, Thomson. 



This genus differs from Thamiarcea in having the hinder angles of the 

 thorax well marked, and the first joint of the intermediate tarsi plainly 

 shorter than the second ; the elytra also are furnished with a plain raised 

 fold at the apex towards the posterior external angle : the species are 

 found exclusively in ants' nests ; three are found in Britain, one of 

 Avhich is placed by Thomson in his sub-genus Luprocorrhe ; this, 

 however, can hardly be separated from Notuthccta, and together with 

 Kraatzia, Muls. and Eey, is usually included under that genus. 



N. flavipes, Grav. Rufo-piceous, with the head and central portion 

 of hind body blackish ; rather a broad and robust species ; head black 

 and shining, broad and short, finely and indistinctly punctured ; antenna? 

 pitchy, pale at base, rather long, scarcely thickened towards apex, 

 joints 2-3 about equal in length, rather long, 4-10 not difi'ering much in 

 length, fourth rather longer than broad, .5-0 hardly, 7-10 slightly.
