352 THE ENTOMOLOGIST. 



ErlocoUas. Two specimens. In collections of Mr. F. Moore 

 and my own. Mr. Moore's specimen from Punkabaree, 1500 ft., 

 Eastern Himalayas ; my specimen from Corea. 



This ab. of C. erate and the one of E.Jieldii together form an 

 instance of the third type of aberration or overlapping ; the male 

 ab. schilli of P. parts is a case of the second or transitional ; and 

 as an instance of the first or adventitious aberration (which is 

 not, however, referable to secondary sexual character), I may 

 mention the type-specimen of Calinaga siidassana (Melv. Trans. 

 Ent. Soc. 1893, pi. 8). On closely examining the lozenge- or 

 spindle-shaped spot (beautifully shown on the plate) on the 

 costal nervure of hind wings, and which only the type-specimen 

 shows, it is seen to be a split in the nervure at a certain point, 

 on both hind wings and at the same place, where the nervure 

 forks, and, having diverged about one-fourth of an inch, the two 

 separate limbs approach, anastomose, and continue as the 

 costal nervure. It is here interesting to note that a male of 

 C. buddka in my collection has, at about the same position on 

 the costal nervure of hind wings, on one side only however, a 

 small short spur or veinlefc given off from the costal to the costal 

 edge of the wing. Mr. Hastings Dent's specimen of C. siidassana 

 does not show the split, nor does the third specimen of this 

 species in the Hon. Walter Eothschild's collection. This aberra- 

 tion of siidassana may be classed along with monstrous aberra- 

 tions, but it may, along with the male of C. huddha mentioned, 

 have a morphological significance as yet not understood. 



SILK-PRODUCING LEPIDOPTERA. 

 By Alfred Wailly. 



(Continued from p. 279.) 



African Species. 



The African silk-producing Bombyces, excepting a few, are 

 yet unknown as silk-producers ; I can therefore only give the 

 names of some species : — In Sierra Leone, Satarnia alenda and 

 S. plujediisa, Drury. In Natal, Actias mimosce. In Senegal there 

 is a species with a closed cocoon, Attacus faidherbia, which must 

 then be an Antliercea, and it may be the species otherwise known 

 as Bombyx bauhinice. 



The wild silkworms of Madagascar are better known, thanks 

 to the liev. P. Camboue, who has written numerous and interest- 

 ing reports on this subject, which have been published in the 

 ' Bulletin ' of the Societe Nationale d'Acclimatation de France. 

 I shall therefore reproduce an article from the ' Bulletin ' of 

 June, 1885, by the Rev. P. Camboue.
