of Fossorial Hifmenoptera. 255 



Fargeau does not mention any spots on the face of sexjyunc- 

 tatus : that species is found near Paris ; S. hi^mnctatus may 

 prove to be an extreme variety of it. 



Salius doi'salis. 



Female. Length 4 lines. Black, with the pro- and meta- 

 thorax red. The anterior margin of the clypeus and tips of 

 the mandibles ferruginous. Thorax : the metathorax with the 

 posterior lateral angles produced and spiniform ; the wings 

 slightly fuscous, the nervures black ; the calcaria at the apex 

 of the tibiffi Avhite ; the intermediate and posterior tibiaj and 

 tarsi with a few slight short spines. Abdomen : the base, the 

 apical margins of the first and second segments, and the basal 

 margin of the latter also, with silvery-white pubescence. 



Hah. Angara (Siberia). 



Genus Chirodamus, Halid. 



Head narrower than the thorax, convex in front ; antennse 

 short, thick, and convolute in the female ; labrum exposed. 

 Thorax : narrowed anteriorly from the base of the wings ; 

 prothorax short and transverse ; the metathorax short, not 

 abruptly truncate, the margins being rounded ; wings with 

 one marginal cell, pointed at its apex ; three submarginal 

 cells ; the first one third longer than the third, which is nar- 

 rowed towards the marginal one ; the second much narrower 

 than the third, and subquadrate, being a little longer than 

 broad ; legs of moderate length, anterior pair raptorial, short, 

 and incrassate ; the claws stout, with a large pulvillus between 

 their fork. Otherwise as in the genus PompUus. 



Mr. Haliday has not given any characters whereby to di- 

 stinguish the insects belonging to this genus ; they are, how- 

 ever, indicated by him in his remarks. It will be seen that 

 the characters which separate this genus from that of Planicepts 

 are the narrow head, non-prominent eyes, and the wings having 

 three submarginal cells, and the conspicuous distinction of 

 having the front of the head convex. The abdomen is of the 

 ordinaryformof PompiV^.s, convex, and in no degree compressed. 

 As indicated by ]\Ir. Haliday, tlic situation of this genus is 

 next to Flanieeps. 



Chirodamus dlstinctus. 



Female. Length 6 lines. Black : the head, thorax, and fe- 

 mora with long erect black pubescence, not very dense. The 

 clypeus widely truncate, the truncation slightly incurved ; the 

 labrum subangular ; the apical portion of the mandibles fer-
