1896.] BUTTERFLIES OF THE FAMILY HESPERIID^. 89 



contains two perfect females of this fine species, taken at Gaboon 

 by Mocquerys according to the labels. The female is like the 

 male, but larger in size, and with the underside of the wings 

 redder than in the figure of the type given by Karsch. It is 

 singular that during the eight years in which I have had a collector 

 constantly residing and at work for me in French Congo, this 

 species has not turned up. It evidently must be very rare, or 

 very local in its distribution.

This species has been labelled P. ruralis by Mons. Mabille in 

 several collections, and has been sold under this name by Dr. 

 Staudinger. I can find no account of the publication of the 

 species by Mons. Mabille, and believe the name to be hitherto 

 unpublished, except as stated, and as it is once or twice referred 

 to in the writings of Mons. Mabille. It seems at all events to 

 have totally escaped the notice of the compilers of the ' Zoological 

 Eecord ' and Bertkau's ' Eegister,' and, though I have twice asked 

 Mons. Mabille to inform me where the species is described, he 

 has failed to include an answer to this question with the other 

 information he has so kindly and generously given me. The 

 identification of this species with P. calpis, Ploetz, by Dr. Karsch 

 is based upon specimens so labelled in the Berlin Museum ; but 

 these are not types, and came from Senegal, and were not labelled 

 by Ploetz. There is, further, no agreement whatever between the 

 insect figured by Karsch and the description of P. calpis given by 

 Ploetz. A comparison of the figure given by Karsch shows the 

 entire identity of the insect with Hewitson's If. cylinda. The true 

 calpis is figured in this paper. It is the female of Hidari coenira, 

 Hew. 



C. cylinda is a crepuscular insect, as I have been informed by 

 the late Dr. Good. It only appears at dusk in the morning or 

 the evening, though occasionally on dark and cloudy days it may 

 be seen upon the wing. I have one or two examples which were 

 taken at lamp-light, having flown into the room after dark.
