142 Dr. F. A. Dixey on 
of “dry-season” forms. The large proportion of Pierines 
to the whole number is remarkable ; as also is the general 
resemblance borne by the whole assemblage to the butter- 
‘fly fauna of Aden. It was remarked by Dr. ‘Butler in 
Proc. Zool. Soc., 1901, p. 25, that the collection made by 
Captain Dunn on the Bahr-el-Zeraf (White Nile) had a 
very Aden-like aspect, and in particular that it contained 
all the forms of Limnas chrysippus, Linn., just as they occur 
at Aden. In Somaliland, as is well know n, the prevailing 
form of L. chrysippus is L. klugti, Butl., w ith a sprinkling of 
its modification L. dorippus, Klug; in other respects the 
present collection recalls the Somaliland fauna almost as 
distinctly as it does that of Aden. 
It will be noticed that Mr. Loat’s insect-collecting was 
limited to a very few occasions, and to only three months 
in the year. This will no doubt account for the absence 
from his collection of a few species which occur in that of 
Captain Dunn (Joe. cit.). Among such are Precis bodpis, 
Trim., Atella phalantha, Drury, and especially Hypolimnas 
misippus, Linn. There is no new species among Mr. Loat’s 
captures, but they include the male of Pnacopteryx 
venatus, Butl., of which the female only has hitherto been 
known to science. 
Subjoined is an account of the places and dates of 
capture, as carefully recorded by Mr. Loat, together with a 
list of the specimens taken on each occasion. It has been 
thought worth while to preserve his details, even to the 
time of day at which the captures were made.

T. antigone group. It is barely, if at all, distinguishable 
from 7’ evagore, Klug (7. saxeus, Swinh.). See below, p. 161.
