372 XOVITATES ZOOLOGICAE XXIV. 1917. 



There has always been a dispute as to what numida and inaroccana were. As 

 the types of both these forms are in the Tring Museum, tlie matter is easily 

 settled. The two specimens of numida are labelled as coming from Nemours. 

 They are as large as pavonia-rruijor, and have the outer margins and apex of 

 wings suffused with ohve-yellow as in pavonia-7najor, but the basal three-fifths 

 of hindwings arc much paler and the obUque zigzag double hne running outside 

 the ocellus of the forewing is not contiguous to the ocellus as in pavonia-major, 

 but is well outside the ocellus and very sharply zigzag as in atlantica. When Dr. 

 Jordan and I saw these specimens we at once said these must be hybrids ; two 

 years ago I obtained from Mr. Watson of Manchester two artificially bred 

 atlantica x pyri in which the <J parent was atlantica ; these arc much smaller 

 than the two numida and more hke atlantica. I am now therefore convinced 

 that numida Aust. is the reverse cross to atlantpyri Niep (sic ! !), i.e. o pavonia- 

 major X ? atlantica. 



As regards marocc-ana Aust. the type-specimen is labelled Tlcmccn ! ! and 

 I can see no difference between it and typical atlantim. Dr. Vallantin (Bull. 

 Soc. Entom. 1898) described an aberration of atlantica as var. motheri from 

 DjidjelH ; it is very dark and strongly washed all over with pink. I have 

 seen a similar specimen in the collection of the late Captain Holl. I have only 

 seen one pavonia-major from Jlauretania (Oran), but Mr. Oberthiir has one from 

 Oudjda and one from Ain Draham.]

We have taken this at Alger, and I had two damaged specimens brought 

 me at Souk-Ahras, one only of which could be preserved.
