320 Mr. R. E. Turner on Fossorial Uymenoptera. 



Uih. "RnrracKpore, N.E. India; Mathcran, W. India; 

 Ciiapra, Bengal. 



Vorv closel}' allied to these three forms of yiif/ricans is the 

 Austialiari JS\ rctiuria, Turn., in which the punetur£S o£ the 

 nicsonotum are almost obsolete and the eyes n(>arer to each 

 other on the vertex. I do not consider that small differences 

 in the comparative length of the abscissa3 of the radius are to 

 be relied on in this genus; there seems to be a slight indi- 

 vidual variation in this respect. iV. maliensh, Cam., from 

 the Si'VclRlh's, differs from reticulata in the longer aud rather 

 narrower radial cell.

Although the tarsal ungues are toothed in this species in 

 the I'emale, the very different form of the pygidial area bhows 

 that it is not closely related to Motes. 



Hah. Ea^it Africa from JMashoualand to Witu ; West 

 Atrica,'Gambia and Gold Coast. 



Doubtless this species ranges through the whole of tropical 

 Africa. 



Kotogonia deceptor, Turn. 

 Ilotes deceptor, Tm-n. Ann. & Mag. Isat. Hist. (8) xvii. p. 253 (1916). 



This is closely related to JS. crcesus, and is not a Motes. 

 It may possibly prove to be a colour-variety of crcesus, the 

 structural differences being very slight.
