Manatha edwardsii Heyl. as a synonym of Platceceticus gloveri 

 Pack. " Pseud op syche" exigua has been carelessly referred here. 

 It can have little in common with the Psychidae.

ENTOMOLOGICAL SOCIETY OF LONDON, Oct. 4, 1893. "Mr. F. Merri- 

 field exhibited specimens showing the effects of temperature in pupal 

 stage on several Lepidoptera. Vanessa polychloros-was much darkened, 

 especially towards the hinder margin, by a low temperature. Vanessa 

 c-album showed effects on both sides, especially in the female; they were 

 striking on the underside. Several examples of the striking effect pro- 

 duced by temperature on the Summer emergence (Prorsa) of Araschnia 

 levana were exhibited. Some Vanessa io showed the gradual disinteg- 

 ration, by exposure to a low temperature, of the ocellus on the fore wing, 

 which in extreme specimens ceased to be an ocellus, and was a remark- 

 able confirmation of Dr. Dikey's views of the origin of that ocellus. Mr. 

 Goss stated that, in his experience of V. c-album, the form with the pale 

 underside was the first brood, occurring in June and July; and that the 

 second brood, from the end of July to October, was invariably darker on 

 the underside. ' ' Similar interesting studies have been made in this country 

 by Mr. W. H. Edwards and others. If our species of Safynix were studied 

 from a geographical series and from the different seasonal broods with the 

 effect of cold and altitude borne in mind, a few names would probably 

 fall into the second line. 



* An undetermined species, probably also undescribed, from southern Arizona and New 

 Mexico.
