XVIII. Descriptions of new Species of Mantispide in the 
Oxford and British Museums. By J. O. Wexst- 
woop, M.A., F.L.S., &c. 
[Read Ist April, 1867.] 
I sec, by way of supplement to my memoir on the Mantispide 
(Trans. Ent. Soc. 2nd ser. vol. i. p. 252) to offer to the Society 
descriptions of several new species, chiefly belonging to the curious 
sub-genus Trichoscelia, mostly collected on the Amazons by 
Mr. Bates, and contained in the Hopeian Collection at the Ox- 
ford Museum. [I find that the species of this little group differ 
considerably in the thickness and setose clothing of the hind tibiz, 
varying in this respect in the opposite sexes of the same species. 
To these I have added several other species of Mantispa, two 
of which are in the British Museum, and a fine new species of 
Nemoptera, in the same collection.
