after that lias brauchecl and become marginal. They are generally largest towards the 

 base of the wing. 



The number on various species is as follows : —

Pimpla TurionellcB, 7- 



Pinipla (England), 6. 



Pimpla varicornis, 10. 



Pimpla (N. America), fig. 21, has 2 strong upright hairs at the commencement of the row of hooks; 

 12 follow regularly; but between the 6th and 7th and the 9th and 10th, and in a Hne with 

 the hairs, is a small hook standing up and not re-curved. In all these species of Pimpla, 

 there are rather upright and strong hairs at the commencement of the row of hooks. 



Rhyssa, 13-14. 



Ephialtes, 6.

 Crypius (Europe), 14. 

 Hemiteles, 4. 



The distal hooks are of similar form, and begin before, on, or after the branching of 

 the costal nerve in Sphegid^ {S2)hex) and Pompilid^e. 



Sphex {Qra.z\\) has .36, beginning on branching of costal nerve (7 ? sub- basal hooks). 



Pompilus bicolor 24, beginning on branching of costal nerve (no sub-bas.). 



Pompilus 44, beginning before branching of costal nerve (no sub-bas.). 



Pompilus nitiduliis 21, beginning after branching of costal nerve (no sub-bas.). 



Pompilus Br etonii 23, beginning on branching of costal nerve (7-9? sub-basal hooks). 



Pompilus 35, beginning on branching of costal nerve (2 sub-basal hooks ?). 



Macromeris violaceus .... 32, beginning after branching of costal nerve (14 sub-basal hooks).

Pepsis limbata (fig. 32 a) . . . 30, beginning on branching of costal nerve (7? sub-basal hooks). 



They are of similar form, and begin where the upper and lower divisions of the costal 

 nerve unite and again branch, in Vespid^, Eumenid-E, ScoLiADiE, and Sphegid.e 

 {Chlorion).
