Obs.—This species is very nearly allied to M. Chilensis, Hagen, 
Stett. Ent. Zeit. xx. 408, which Dr. Hagen appears to be disposed 
to unite with Trichoscelia. In that species (for a specimen of 
which—of the male sex—I am indebted to that distinguished 
author) the cells of the wings are less numerous (6 or 7 oblique 
ones in the fore wings) than in the specimen above described, and 
the anterior femora are armed with very strong spines, which are 
wanting in my species. It does not appear to me, however, ad- 
visable to unite M. Chilensis and the present and next described 
insects with Trichoscelia. The cylindrical tibiz of the four hind 
Jegs, and the increased size of the hind wings (although not so 
large, as compared with the fore wings, as in the typical Mantispe) 
remove them from the true Trichosce/ia, but then the ovate form 
of the fore wings constitutes them a distinct section in the genus 
Mantispa. ‘The following are descriptions of two more species be- 
longing to the same section.
