African Species of the Genus Acraca. 218 



" Pupa waxy white with the usual fine black lines on the 

 wing covers and black spots witli orange centres on the abdo- 

 minal segments. 



"Feetls on CommcUna." 



Every kind of intermediate form may be observed in a 

 loug series. None of the forms seems to be specially 

 characteristic of any particular locality, though the 

 cdeip2)ina form seems to attain its maximum development 

 in West Africa. Long series of examples have been bred 

 by Mr. Lamborn near Lagos, and the majority of these 

 broods consist of two forms, viz. infvscata and lycia. The 

 latter are somewhat unusual in having broad suffused 

 orange internervular markings on the hind margin of the 

 secondaries on the underside, also some basal markings of 

 the same colour. 



Examples of the lycict form may have the ground-colour 

 pale creamy yellow. Another now before me has the f-w. 

 sepia black except for the subapical white band. 



An exceptionally fine $ example of the typical form 

 from Chishi I., L. Bangweolo, measures rather over 70 mm. 

 in expanse and has the ground-colour ricli red brown. 



In Proc. Zool. Soc. 1900, Butler quotes from Crawshay 

 who writes that f/^rcf/o?; "is a graceful insect . . . alternately 

 flapping its wings and skimming along in its flight very 

 differently to the other Acracinae." 



Dr. Longstaff has noted a disagreeable odour in the ^ 

 when crushed, and Marshall has noted that the insect has 

 a bitter taste. 



The species appears to have no very near allies.
