Fam. Papilioxid.k. 



Papilio dardaxps Brown. 



This Swallow-tail occurs sparingly in patches of forest in the 

 Lualaba valley in Katanga and in the valley of the Kalungwisi 

 river in N.E. Rhodesia. These points would seem to be the 

 south-east limit of its distribution. The only females observed 

 belonged to the form hippocoon Fabr. The males have the curious 

 habit of following regular routes in the forest-clearings, which 

 they traverse over and over again at intervals of three or four 

 minutes. 



Papilio hesperus Westw. 



I saw a few worn specimens of this fine species on the Lufupa 

 and Lubudi rivers, x., and found it not uncommon in the 

 valleys of the Kalungwisi and Lof u, viii. and ix. It is usually to 

 be seen flitting round the outskirts of patches of dense forest. 



Papilio constaxtixus Ward. 



A widely distributed species. Generally taken near the ground 

 among grasses, rocks, etc., on wooded hillsides. 



Papilio mackixxoxi bexguell,e. 



Papilio machinnoni bengiiellm Rothsch. & Jord Nov. Zool. xv. 

 p. 253. 



This is a scarce insect frequenting dense forest. I met with it 

 on the upper Kafue river, x., and at Kambove, ii. It is wary 

 and a strong flier. 



Papilio phorcas Cram. 



Not uncommon in the Lualaba valley, iv. and v. Not observed 

 elsewhere. 



Papilio xireus L. 



A widely distributed insect but not often abundant anywhere. 

 It chiefly frequents low-lying river-valleys and I did not meet 

 with it in high plateau country. 



Papilio demodocus Esper. 



Ubiquitous. Flies lower than most of the larger Papilios. 



Papilio pylades axgolaxus Goeze. 



This species is ubiquitous, and on the wing at all seasons. It 

 usually frequents somewhat open country, and may be taken in 

 numbers at damp mud. 



Papilio taboraxus Oberth. 



I met with this species only on the upper Chambezi, iv. and 

 x., and on the Lofu river, viii. It resembles the preceding 



species in its habits.
