204 Mr. G. T. Bethune-Baker’s notes on Chilades galba. 
they arise being so fine and minute that they are invisible 
except under a high-power objective; in galba and also in 
phiala, but particularly in the latter, they are coarser, and 
the hairs are shorter and denser. The falces in laius are 
longer and finer than in either of the other two species, 
but they all have the same short, sharply upturned little 
hook at the tip; in laius, however, they are fixed well 
below the arms of the tegumen, whilst in both galba and 
phiala they are fixed so close beneath the arms as to be 
practically almost attached to them. The slight differ- 
ences of the aedoeagus are best seen from the figure, being 
little more than relative size and length of the taper. 
A comparison of the underside of the perfect insects at 
once shows the relationship with the Indian laius, the 
general pattern being very similar. 
My descriptions and figures are taken from specimens in 
the British Museum, the one being a specimen taken in the 
Plain of Jenin, Palestine, by Miss Fountaine and agreeing 
exactly with the coloured figure of galba given by Lederer, 
and the other is from Groum-Grshimailo’s type of phiala 
out of the Elwes collection and now also in the National 
Collection. 
In the course of my examination of these specimens I 
found mixed with them several others which were evidently 
belonging to the genus Zizeerva, Chapman, and were either 
lysimon or karsandra: of one of these from Beirut I have 
mounted the genitalia, and it turns out to be karsandra. 
This led me to examine several in my own collection from 
Egypt and Algeria, all of which are karsandra; the range of 
this species will therefore be thus extended westward to 
this extent.
