of area- 7 and 8. These patches are distinct on both .surfaces, 

 but especially on the under. In addition to the specimen 

 taken on July 27, a male of the type form taken Dec. 15 

 exhibits extensive injuries evidently inflicted by enemies, the 

 anal quarter of both hind-wings being torn away symmetric- 

 ally. Furthermore, 22 males of the type form and 7 of 

 carpenteri exhibit smaller injuries, of which the great majority 

 were inflicted at the anal angle of the hind-wing, and, from 

 their form, almost certainly by birds. Two female H. misippus 

 accompanied the Pseudacraeas — one of the inaria form 

 " caught at the same time and place as poggei " on Nov. 3, 

 and one misippus with slight development of white on the 

 hind-wing, taken Nov. 11.] 



('apt. Carpenter had not as yet recorded the proportion of 

 dorippus to chrysippus at Lulanguru and adjacent localities, 

 but further to the east and north it was known that dorippus 

 largely predominated. Thus Capt. \Y. A. Lamborn had written 

 on .1 une 3, 1916 : — 



" 1 have been much struck by the abundance of dorippus, 

 the type form being almost absent. Inarm also seems to be 

 more numerous than the type, and encedon is almost invariably 

 a brown form [daira] without any subapica] bar at all." 

 Out of hi l>. chrysippus collected by ('apt. Lamborn in north 

 centra] ex-German East Africa, to be recorded with preei e 

 localities by Dr. Eltringham in our Transactions for 1917, 

 33 were dorippus, 3 all/inns, Lanz. (a more or less white-hind- 

 winged dorippus), 3 chrysippus, and I with less white on the 

 hind-wing than alcippoides, .Moore. Out of 21 Acraea encedon, 

 L., It) were daira, Godm. and Salv., 3 encedon (one approach- 

 ing infuscata, Stand.), and 2 lycia, F. 



(apt. Carpenter's captures were made on what was prob- 

 ably the border of the area in which the above proportions 

 obtained, and it was likely that if the Pseudacraea had pene- 

 trated still further into this area the proportion of the new 

 form would be found to be much higher to the north and 

 east.

 the type form of /'. poggei some three or four hundred miles 

 south and a little to the wesl of Lulanguru. wrote to Prof.
