Lowne, R. T. On the Modifications of the Simple and Compound Eyes 
of Insects. Phil. Tr. clxix. pp. 577-602, pis. lii.-liv., woodcut. 
Observations with improved methods and instruments on the structure 
of the stemmata and compound eye in Eristalis tenax^ of the compound 
eye in I'ipula, Formica rufa^ Syrphus, Musca vomitoria, Stomoxys^ Tahanus^ 
and Vanessa atalanta^ and of the eye in Agrion puella, Acridium, Sphin- 
gidce, and Noctuid moths. The highest development of the aggregate eye 
is in the so-called compound eye of the Nematocerous Diptera, and of the 
Hymenoptera. Grenacher’s observations, made on immature insects, do 
not accord well with those of the author. The form of eye typical of the 
Noctuce is th^ conic, which is termed proto-conic in its embryonic condi- 
tion, and sclero-conic in these moths ; this conic eye is the nearest 
approach to the primitive eye, but is remarkably modified into (1) hydro- 
conic (with the cone replaced by fluid, and the recipient structures 
reduced to their simplest condition), as in Brachycerous Diptera and 
Odonata, and (2) tetraphoric, with very complex tetrasome and tetra- 
phore, as in some diurnal Lepidoptera examined and in A cridkim. Muller’s 
theory of mosaic vision is on the whole accepted. The number of species 
and genera as yet examined is, however, admitted to be far too small to 
found a correct opinion as to typical structures.
