between the Lusika Eiver and Chimoia's the weather was dull and 

 rainy and unfavourable for collecting. Had it been fine I might 

 have seen and caught a few more specimens. 



" P.S. — The Pungwe Valley, in which I caught a few Butterflies 

 last September and October, is covered with forest and intersected 

 by numerous streams. The altitude is here, however, below 1000 

 feet. Below Sarmento, and from there to the coast, there is a 

 great deal of open country covered for the most part with ex- 

 cessively long grass." 



The tract so well described by Mr. Selous is a belt of not more 

 than about ten miles in width, running east and west between 

 S. lat. 18° 50' and 19°, and E. long. 32"^ 32' and 33° 20'. From 

 Chimoia's to Sarmento and the Pungwe Eiver is a narrower con- 

 tinuation of the same belt to the eastward for another sixty miles, 

 at first a little north but afterwards slightly south of the 19th 

 parallel. From the existing maps the entire tract seems to be less 

 than 200 miles south of the nearest reach of the Zambesi. 



Including two forms of Mycalesis which I have not been able to 

 determine with certainty, and two of Terias which I cannot 

 satisfactorily place, Mr. Selous's collection contains representatives 

 of 166 species, represented by over 1100 examples. This is a very 

 good result of three months' collecting, but it must not by any 

 means be regarded as completely representing the Butterfly fauna 

 of the district, as there can be no doubt that many forms known to 

 range both north and south of Manica, although not represented 

 in Mr. Selous's collection, must occur in the intermediate tract. 

 Fifteen such species, for instance, are recorded from the Zambesi 

 Valley and from extra-tropical South Africa— ten of them ranging 

 widely also in other parts of the continent— and these can hardly 

 be absent from Manica. Moreover, a certain proportion of species 

 are sure to be peculiar to the dry-season months, during which 

 Mr. Selous had not the opportunity of collecting. 



Of the 165 species in the collection 44 are of general distribution 

 south of the Sahara ; and of the remainder, 26 (of which 9 appear 

 to be undescribed) seem peculiar to the South-Tropical area. As 

 many as 51 inhabit both the South-Tropical and the South Extra- 

 tropical areas, and 13 others are also found in both these areas, 

 but hitherto, as regards the former area, have been recorded from 

 Manica only. Twelve are dispersed through both these areas as 

 well as in part of the West North-Tropical area, and eight through 

 the two former and also the East North-Tropical area; while seven 

 others inhabit both Tropical areas, but are unknown in the South 

 Extra-tropical area. Three {Deudorix ccerulea, Durhania liilde- 

 gardi, and Pierygosjndea galenus) seem elsewhere to be recorded 

 from the West of both Tropical areas, and one {Lijccena antinorii) 

 from Abyssinia only. . . 



The collection is disappointing in one respect, viz., its deficiency 

 in mimicking species. There is no example of any form of Euralia 

 or Pseudaercea, and the only imitative Butterflies represented are 

 the female Diadema misippus and two forms of the female Papilio
