1896.]. ON MOTHS FROM ADEN AND SOMALILAND. 257 
Belenois lordaca feeds at Huswah on Caparis galeata, that ‘is, 
if this plant be conspecific with the Aden plant bearing the same 
name (to the uninitiated the plants look allied, but decidedly 
distinct from each other). I suspect that 7. vi also feeds on this 
plant, though I have never yet found a larva in spite of careful 
search. 
Catopsilia larvee feed on Cassia, sp., but I have been unable to 
correctly obtain the specific name of this plant; it is, however, 
allied to adenensis, and may be that species. 
Zesius livia.—Specimens bred from the pods of Acacia edgeworthir 
collected in Gold Mohur Valley. At Haithalhim a number of 
pupe were found under a large stone; from these, too, a species 
of Zesius emerged. 
Limnas.—The larve feed on Calotropis gigantea. 
Seasonal dimorphism does not seem to occur to any extent in 
the neighbourhood ; though it may possibly do so in the case of 
Teracolus calais and dynamene. 
The year 1883 was very wet, heavy rain having fallen in May, 
consequently in July a large number of Butterflies appeared— 
among others, a very brightly-coloured form of 7’. calais (all, I be- 
lieve, females however): this may point to 7’. calais being the rainy- 
season form and 7. dynamene the dry. I never met with this 
unusually brightly-coloured form in after years.—J. W. YERBURY.

_ The following paper contains a record of the collections made 
at Aden and its neighbourhood in the year 1895 by Col. J. W. 
Yerbury and Capt. C. G. Nurse, and of a small Somaliland 
collection made at Zaila. by Capt. Nurse. Ht also includes the 
Heterocera recorded from Aden in a paper by Mr. A. G. Butler 
in the Society’s ‘ Proceedings ’ for 1884 (collected by Cols. Yerbury 
and Swinhoe), and the few Moths recorded from Somaliland by 
Mr. Butler in his paper on the Lepidoptera of Somaliland in the 
Society’s ‘Proceedings’ for 1885, nearly all these species, how- 
ever, being again represented in the collections now worked out. - 
The Aden forms show, as might be expected, a mingling of 
the European, N. African, and Western Indian species, the latter 
decidedly predominating. The number of species is very large for 
such a barren locality, especially among the Pyralide, the number 
of Phycitine being a marked feature of the fauna, whilst the / 
most interesting new form is the archaic genus of the Wola/: 
group. The portion of the paper on the Pterophoride, Tortricidag
