this condition may occasionally be seen in the latter species. 

 Many specimens of P. demoleus from Aden resemble P. bennetti 

 in the narrowness of the pale median band of the hind wing ; 

 they differ, however, in the other particulars. 



Mr. Bennett's specimens were taken on the extreme summit of 

 Jebel Dryet (4900 ft.), settled on a Bedaween's bright-coloured 

 cotton wrap or loin-cloth. The species is a strong flyer. It was 

 not often met with, and never at a less elevation than 3500 ft. 

 It does not occur in the collection made by Prof. Bayley Balfour.

Three specimens, all c? . This species, as remarked by Trimen 

 (South Afr. Butt. A'ol. iii. p. 373) is near E. keithha Wallgr. from 

 the East African mainland. It is also alhed to R. taranis Hew. 

 (R. anchises Gerst.), which has a wide African distribution and 

 occurs at Aden (Butler, Joe. cit. p. 179).

 Ghalansyah and Tamarida." — E. N. B. 



Geuenes NOSTRADAMUS Fabr. (No. 52.) 



One specimen, a $ . This species, which extends throughout 

 the Mediterranean subregion into the North-western districts of 

 India, was not obtained by Prof. Balfour. Specimens from Aden 

 ( var. Jcarsana Moore) are more sandy in colour than the Socotran 

 example. 



The Heterocera collected by Mr. Bennett consist of 26 speci- 

 mens, belonging to 16 species. These have been kindly named by 

 Sir George F. Hampson. There are no new forms among them ; 

 Oligostigma incommoda, which was described by Dr. Butler (Proc. 

 Zool. Soc. 1881, p. 180) from a specimen obtained by Prof. 

 Balfour, does not occur in Mr. Bennett's collection. The Socotran 

 Heterocera, so far as they are known, appear to present a mixture 

 of African and Oriental species, the former predominating, together 

 with some widely-distributed types such as D. pulchella. As in 

 the case of the Ehopalocera, the African element does not seem to 

 be exclusively East African. It is unfortunate that the Moths 

 collected by Eiebeck ' were never determined.
