OF THE HIND WINGS OF HYMENOPTEROUS INSECTS. 
131 
In Ntssonid^e both the veining and the situation of the hooks vary. 
Stizus (fig. 36 a) has 25 distal hooks, commencing on junction before branching. 
Gorytes mystaceus (fig. 37 a), 12, commencing on junction after branching. 
Gorytes Natalensis (fig. 38 a), 25, commencing on junction after branching. 
Mellinus sabulosus, 14, on costal nerve after branching (no junction). 
- 
They commence on or immediately before the branching of the costal nerve in Andre- 
nldje and Apidje, and are large and recurved. They occasionally differ from the pre- 
ceding families in increasing in size after they commence at the centre of the wing.

In MuHlla, fig. 28 a, they grow on the membrane of the wing, above the costal nerve, 
which appears to dip down to make room for them. They are 17 in number, and 
commence before the branching.
