NEW HYMENOPTERA FROM CEYLON. 
Mutillidz and Scoliidz. 
By Rowuanp E. Turner, F.Z.S., F.E.S. 
rT\HE species described in this paper are mostly from the collec- 
tion of Mr. O. S. Wickwar, who is generously depositing the 
types in the British Museum. Most of the Mutillide were collected 
by Mr. T. Bainbrigge Fletcher at Hambantota; from him the 
Museum has also received long series of some species. Most of the 
larger species are identical with those collected by Yerbury at Trin- 
comalee and described by Cameron, but few of the smaller species 
are identical with those from Trincomalee. Most characteristic of 
the Ceylon Mutillide is the abundance of species in which the 
posterior margin of the thorax in the female is furnished with a row 
of rather long teeth ; this group, though not confined to Ceylon, 
seems to be much richer in species there than elsewhere. The 
range of many of the species is probably extremely limited ; for 
climatic conditions at Trincomalee and Hambantota are very 
similar, and the difference of the species in the two localities is 
not likely to be entirely due to insufficient collecting. The 
means of locomotion in the female are so limited that local forms 
are much more likely to be developed than in other families, 
In the genus Tiphia I have observed that the part most affected 
in local races is the median segment ; and in the female Mutillid 
the shape of the thorax seems especially subject to local influence, 
the median segment in the female sex being combined with the 
thorax. 
Mr. Wickwar has pointed out to me that the colour of the head 
and thorax, used as the main points of recognition in Bingham’s Key, 
is not a reliable character; in this I fully agree with him and with 
other authorities.
