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.

Hab. Tropical Western Africa. Very common at Gaboon. 
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unpublished, except as stated, and as it is once or twice referred 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 
Record’ and Bertkau’s ‘ Register,’ 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 H. cylinda. The true 
calpis is figured in this paper. It is the female of Hidari ceenira, 
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.
