inner margins. The antennae are rather short, sometimes 

 slightly thickened towards the apex ; the anterior wings have 

 two submarginal and three discoidal cells, but the second 

 submarginal and third discoidal are enclosed by such very 

 fine pale uervures, that at first sight they are liable to be 

 overlooked; propodeum rather short, abdomen very long and 

 narrow, its first segment channelled at the base, apical 

 segment in the ? with no distinct pygidial area; tibiae and 

 tarsi not spinose. 



The species of the genus nest in the ground, or in de- 

 cayed wood or bramble stems, and provision their nests 

 with spiders ; their cocoons are tough and leathery. Smith 

 says that the cocoons of T. fyulus are separated from each 

 other by a partition of agglutinated sand. 



Kohl, in 1884, gives seventy-four described species of this 

 genus, and says it occurs in all regions ; there are seven 

 Paleearctic species, of which we have three. 



(4) 1. Petiole broader, first segment of abdomen 



not nearly twice as long as the second. 

 (3) 2. Larger, legs entirely black . . _ . . figultjs. 

 (2) 3. Smaller, anterior tibia; pale, at least in front clavicerum. 

 (1) 4. Petiole very narrow, first segment of abdo- 



mcQ twice, or nearly twice, as long as the 



second ATTESUATUM. 



T. figulus, Linn. — Black, clothed with short cinereous 

 pubescence, mandibles red at the apex. Head dull, exceed- 

 ingly closely punctured, face between the eyes nearly flat, 

 clypeus with a slight sinuation in the centre, auteuusB 

 scarcely clavate, the apical joint in the cJ acuminate, as 

 long as the preceding two united; thorax finely punc- 

 tured, wings dusky at the apex, propodeum diagonally 

 rugose, channelled down the centre; abdomen with the 

 basal segment raised at the apex, not quite one-half 

 longer than the second, all the segments especially in the 

 (J with an apical baud of gray pubescence, widest at the 

 sides, apical segment in the ? pilose beneath ; legs black,
