that the larvjs will feed upon any Acacia, and there are many 

 species to be found even in the Bombay Presidency. In Sind, and 

 the Districts of Khandesh, Poona, Sholapur, Bijapiir, Dharwar, the 

 eastern parts of Satara and Belganm and even the eastern outskirts of 

 Kanara, it is very common wherever Acacice occnr and may be found 

 any day, in their flowering season, flying in numbers around these 

 trees in the hottest hours. They are insects of bright sunshine 

 and open places, and fly v/ell and quickly though they do not ever 

 go very far at a time ; they are fond of resting near the ground or 

 even on it, especially where it is covered with the fallen flowers of 

 the foodplant. In the bright sun the Avings are often held half- 

 opened in the position of rest when basking ; the normal attitude 

 is, however, with them closed over the back in the usual lycsenine 

 manner. The habitat is: N. W. Himalayas; Baluchistan; the 

 Punjab ; Oudh ; Bengal ; Orissa ; Central, Western and Southern 

 India ; Ceylon ; Upper Burma : Tilin Yaw (Watson). 



141. Azanus uranus, Butier. — Male and Female. Closely resembles A. 

 ubaldus, Cramer. The male on the upperside has the ground-colour much 

 paler and the terminal edging on both fore and hind wings much narrower, 

 reduced, in fact, to a conspicuous dark-brown auteciliary line, while the two 

 dark spots at the tornal area of the hind wing are more or less obsolescent. 

 In the female on the upperside the ground-colour is sometimes also much 

 paler than in the female of ubnldus, but the suffusion of purplish blue at the 

 base of the wings is often spread slightly further outwards than it is in the 

 female of ubaldus. Underside : Male and female : ground-colour greyish 

 white ; character and disposition of the markings much as in ubaldus, but 

 sometimes faint and not clearly defined, often many of them scarcely trace- 

 able, the transverse subbasal row of black spots on the hind wings then 

 either completely absent or barely visible. The black subcostal spot in 

 interspace 7, though it may be smaller than in itbaldus, is always present 

 while the tornal black spots are always large and prominent in both sexes. 

 Expanse : Male and female, 25-28mm. 



Larva — Is very like that of ubaldus. The " hump " of each segment 

 is, perhaps, more accentuated ; the anal segments 12-14 are perhaps 

 shorter, have certainly fewer dorsal depressions round the margin ; the 

 hinder margin is more inclined to be square, the dorsum of these anal 

 segments is not so flat and the second segment is quite semicircular and 

 not waved at the side as in ubaldus ; also the surface is more shagreened- 

 looking, being covered with mimite, more or less appressed, shining, 

 minute, white-transparent, short, broad hairs all over; there is a dorsal 

 depression on segments 2 and 3 and a small, roundish, dorsal depression 

 at front margin of segment 5, The colour is light green with a doreal, 

 reddish band and signs of a lateral, similar one, both often reduced to 

 a faint mark in the centre of each segment; the hinder face of the 

 " humps" is generally yellowish and there is a glint of yellow on the sub- 

 spiracular region ; at the depressions of segments 3-6 the dorsal, red band 

 surrounds them and does not extend into them; the depression on segment 

 2 is black and has a minute lateral black tubercle bearing a black hair. 

 The head is very light yellowish-brown with the clypeus outlined dark- 

 brown ; otherwise it is as in ubaldus. The spiracles are minute and whitish 

 in colour. L : 10mm ; B : 3mm. 



Pupa. — The only difference between this and that of ubaldus is that this
