The following times of appearauce are given — January to March, 

 June, August, and September ; but the following species was mixed 

 up with the specimens of P. evanidus. 



53. Pyrgus galba. 



Hesperia galba, Fabricius, Ent. Syst. iii. (1) p. 352 (1793). 



Eight specimens. Kurracliee. 



The unbroken creamy white band across the centre of the secon- 

 daries on the under surface readily separates this species from the 

 preceding, as also the straighter and continuous subbasal white line ; 

 as a rule, but not invariably, the under surface of P. galba is darker. 



Heterocera. 

 Sphingid.e. 



54. Ch^rocampa nessus (No. 1). 



Sphinx nessiis, Drury, 111. Exot. Ent. ii. p. 46, pi. 27. fig. 1 

 (1773). 



One specimen. Belgaura. 



" One specimen taken in October " (C. S.). Of other species found 

 at Kurrachee are mentioned ; — C. celerio, rarely in November and 

 December; C. eJpenor (probably C.fraterna'), one specimen, probably 

 taken in December, but the month not recorded at the time ; and 

 C. oldenlandice, one specimen in December ; Deilephila livornica, 

 one specimen taken in March, 



55. Pergesa acteus (No. 2). 



Sphinx acteus, Cramer, Pap. Exot. iii. pi. 248, A (1782). 



One specimen. Belgaum. 



The only other species of the family noted by Major Swinhoe are : — 

 Cephonodes hylas, one specimen of which was taken at Kurrachee 

 in December ; Daphiis nerii, taken from. March to May ; and 

 Acherontia morta, which is common in July and August. 



Respecting D. nerii, Major Swinhoe says : — " There appear to be 

 three broods here, one after the other. I have taken caterpillars 

 full-grown in all three months on the oleander which abounds 

 everywhere in these parts : the caterpillars eat the flower only of 

 the double garden oleander, and the leaves only of the wild single 

 oleander. How this is I can't explain ; but it is a fact I have 

 carefully observed both in the jungles and the gardens here and 

 when rearing them in my house. They are emerald-green at first, 

 then turn dull yellow, and finally black before they leave off feeding; 

 they burrow a few inches into the earth at the roots of the oleander, 

 make a smooth cell, spin a very little silk, and the moth emerges in 

 from 16 to 20 days. Out ot 5 caterpillars in my breeding-cage, 

 3 became moths in 16 days after the chrysalis was formed and 2 in 

 20 days, there being one male in both instances."
