Pp. 1-29 give a free translation of a memoir published by the author 
in the MT. Miiuch. Ent. Yer. 1878, accompanied by some notes relative 
to recent literature; at p. 30 commences an original memoir, entitled, 
“ Nouvelles et anciennes experiences,” relative to the perception of forms 
and colours. He describes experiments he made with Bombi and Wasps, 
showing that the former are very sensitive to colour, and he considers it 
certain that Insects perceive more or less distinctly the forms of objects ; 
argues that this is consistent with Exner’s accepted views, and criticises 
Plateau’s recent paper on the perception of the forms of objects by 
Insects. He states that he is still unable to comprehend the functional 
value of ocelli to those Insects that possess also facetted eyes. At p. 145 
he commences an account of a series of experiments directed to ascer- 
taining whether the perception of the ultra-violet rays by Ants, is a 
function of the eyes, or of the surface of the body, and decides in favour 
of the eyes. He then discusses the photodermatic, or dermatoptic sense, 
and gives observations on the faculty of recognition in Ants ; and note 
on the function of the ocelli, and on the instinct of direction. Pp. 1 82— 
214 contain a good discussion of the sense of smell, and the function of 
the antennas, and detail some observations on Insects whose anntenas 
had been amputated. He next treats of the sense of taste, and then moro 
briefly on hearing and touch, and ends with some general remarks and 
considerations on the mental faculties of Insects. [For notice, see J. R.
