decima). B. E. Z. xvi. pp. 49-124. 
100 new species and some new genera are characterized ; the latter inci- 
dentally, at the end of specific descriptions. This " century " completes the 
work ; and some general observations, corrections, and additions, with an 
index to it as a whole, are given, pp. 112-124. The genera Triglyphus^ 
Arthropeas, Bolho7iiyia, Synamphotera, Cacoxenus, Stilpon, and Rhicnoessa, 
founded by the author in other publications, are quoted, with proper refer- 
ences, at p. 113.

From varied experiments and observations upon the eyeless larvae of 
Lucilia ccesar and Eristalis tenax, the author concludes that they not only 
perceive light, but immediately appreciate its intensity and the direction in 
which it comes, that this sensibility is not by means of the antenniferous 
organs, and that it is only completely developed when the larvje are full- 
grown. The name actincssthesia is proposed for this sense. The plates are 
reproductions of the actual movements of the larvae under the influence of 
light of various natures.
