pupa-skin was very similar to those of other Zygaenids. The 

 imagines exhibited were all aberrations, and consisted of 

 females of the ab, flaviUnea, with bright yellow nervures ; 

 a large male and several females of the ab. striata, with the 

 red spots more or less confluent and developed into streaks ; 

 also, an unique female aberration in which the wing, from 

 the base to far beyond the centre was entirely crimson. 



Mr. Warburg exhibited a long series, showing considerable 

 variation in colour and curve of line, of what are considered 

 on the Eiviera to be typical Bomhyx quercus and ab. spartil, 

 with a few preserved larvie of each. According to Hiibner, 

 the insect he calls spartii differs from quercus in being 

 darker brown with a white dot instead of a lunule, and a 

 narrower straighter band sharply defined outside in the S- 

 The fringe of hair was in the male dark brown instead of yellow 

 ochre. This description on the whole fits fairly with both 

 the S. French (Cannes) varieties, which are differentiated by 

 the colour of the larvae, spartii being more fulvous than 

 quercus. According to Guenee this difference is constant, a 

 point which he said he was hoping to ascertain soon. Guenee 

 separates $ $ of spartii from quercus by the following 

 character, that spartii has the band of the forewing whiter in 

 colour than that on the hindwing, a character which however 

 appears to be present in Cannes quercus. His specimens of 

 both pupated about May, and emerged from 28th July, 1896, 

 to end of October, ovipositing as soon as paired. Some ova 

 were still unhatched and a few larvse were already in their 

 second skin. He also exhibited a series of Aberdeen Boinhjx 

 callunce and some Swiss B. quercus. 



Dr. Sharp exhibited a specimen of a lepidopterous insect 

 that had been alluded to in " The Entomologist's Monthly 

 Magazine," Sept., 1896, p. 201. It was a caterpillar which 

 had received the eggs of a parasite on the anterior part of the 

 body; the abdomen, nevertheless, went on to the pupal meta- 

 morphosis, while the head and thorax remained attached to 

 it in the caterpillar stage. He also called attention to some 

 peculiarities in the pupa of Flusia uwneta, pointed out to him 

 by Mr. Fleet ; in this species the pigmentation varies greatly 

 in extent, and is sometimes entirely absent.
