and is straight, subcylindrical, thin, at the end olitnse. The ventrnl lobe is cnrved 

 upwards and inwards ; it is long and jioinfed, forming a strong hook, of which the 

 point is about on a level with the jienis. In couseqnence of the feeble development 

 of the middle lobe the |ienis is not concealed in a ventral view. The stronulv 

 developed ventral lube re])laces to a certain exteut the feeble middle lobe.

The insect described by Aurivillius, I.e., p. 139, from Kameruu as Precis 

 milonia ab. (hybr. ?) pelargoides, and which he suggests to be possibly a hybrid 

 between Precis sinuata and pelarga, is the " wet phase " of P. sinuata : — 



P. sinuata ( ^- P^^^^rgoides = wet phase. 

 I f. sinuata. = drv phase. 



>iuata = dry phase. 



Now, it is very curious that this " wet phase " pdargoides is apparently much 

 raver than the " dry phase." One would e.xpect that the opposite obtained in the 

 West African Forest Region. The explanation jirobably is that the two phases are 

 not truly seasonal. The diflereuce in colour and shajie between the two forms is 

 not very conspicuous. 



The S of P. sinuata ( = pdargoides) is easily recognised by the tenth 

 abdominal tergite being short, broad and truncate, the dorsal process of the clasper 

 ending in two short teeth, and tiie ventral lobe of the clasper being sinuate. In 

 the ? there is a short free vaginal process which is rather deeply sinuate. The 

 vaginal process oi Precis pi/riformis is much longer and pointed ; in tugela it is also 

 long, but somewhat sinuate. The ventral lobe of the clasper of tlie S <i oi' tut/e/a 

 and jji/ri/brmis is truncate, not sinuate, and the dorsal process is also difterent from 

 that of sitmata, being wider at the end, and bearing a much longer ventral apical 

 tooth. Moreover, the tenth tergite of pgri/hrmis is longer. 



Precis sinuata occurs from Sierra Leone to the Congo, its range extending 

 eastwards to Nyassaland and Uganda. Our S6 from Zomba (December) and 

 from near Eandawe (only one labelled, April) have the band of the wings mostly 

 deeper in tint than the West African specimens, while the ? ? from near Bandawe 

 have it rather paler than Western ones.
