more tlian lialf-way across, iu the elateroides of Hear it occupied at least two-thirds 

 of the entire distance, whilst iu the gracilis of his ' Insecta Maderensia' it very nearly 

 touched the opposite part of the circumference. The antennae of Trixagus being 

 implanted very near to the inner margin of the eye, he believed that this sulcus 

 had reference to the lodgment of those organs when the insect was in a state of 

 partial activity, and had removed them from out of the grooves of its anteriorly pro- 

 duced prosternura, — an hypothesis which was rendered the more probable since the 

 only species in which he had as yet remarked the impression to be totally absent was 

 one from Madeira (which he had lately described under the name of integer), in which 

 the antennae are inserted further from the eye than in the normal members of the 

 group, and in which, consequently, any such ocular receptacles would be superfluous. 



Mr, Tapping communicated some notes by Mr. Fedarb, of Dover, on Acari found 

 in a photographic portrait-case, alluded to by that gentleman at a former Meeting of 

 the Society; and also a notice, by the same, of the ravages committed by a species of 

 Atropos on the Barbadoes nut, accompanied by drawings of the insects.

Exhibitions.
