Mr. R. Meldola read au extract from a paper by Mr. W. H. Edwards, 

 " On certain habits of Heliconia cliarltonia, L." (Pajnlio, Dec. 1881), in 

 which were detailed the sexual attraction possessed by the female pupae in 

 this species. From the observations of Dr. William Wittfeld, of Georgiana, 

 Florida, it was stated that in some instances connection was effected before 

 complete emergence, and frequently before the wings were fully developed. 



The Rev. W. Deans Cowan remarked that this was a very common 

 habit with Pajnlio Demoleiis, L., in Madagascar, the males being very 

 commonly found attached to the female chrysalids on the sweet lemon 

 trees (Citrus).

 of Lieut.-Col. R. O'Hara, of Galway, a microscopic slide containing a

 genus of Colydiidie, allied to Cossijphodes. I have now drawn up a note on 

 this insect, and Mr. Wilson has made a drawing of it for a woodcut. 



1 hope by these means that the insect may be recognised when it is again 

 met with. In looking at the woodcut it must be borne in mind that the 

 object is transparent, and the upper and lower surfaces are not easily 

 distinguishable. I propose to call it Paramellon sociale. 



" The general characters are those of Cossyphodes, Westw. (Trans. Ent. 

 Soc. Lond., 1850, p. 168). The antennae are, however, 10-jointed, and 

 the club consists of a single large joint only. When retracted they are 

 completely hidden in a cavity, as in Cossyphodes. The apical joint of the 

 maxillary palpi is rather large, obliquely truncate at the apex. On each
