70 SPHINGIDiE. 



thorax and abdomen. Species very similar to Psilogramma 

 menephron, from which they may be distinguished by the 

 naked stripe on the inner side of the second segment of the 

 palpus in the latter species. 



" c£$. Antenna long and slender, with a long and slender 

 hook. Palpus large, prominent, second segment almost 

 as broad in side-view as long. Eyes large, not lashed. Legs 

 long ; tibiae not spiny ; fore tarsus without prolonged spines, 

 first segment shorter than segments 2 to 5 together ; mid- 

 tarsus with very strong basal comb which terminates abruptly, 

 being continued by much shorter bristles ; comb of hind 

 tarsus also prominent, the spines gradually shortening distad : 

 spurs long, long apical one of hind tibia at least two-thirds 

 the length of the first tarsal segment, which is longer than the 

 tibia and also the other four segments together ; hind tarsus 

 more than twice the length of the cell of the hind wing (measured 

 along SC) ; SC 2 and R 1 of hind wing on a rather long stalk ; 

 D 2 very oblique. With pulvillus and paronychium, the latter 

 with two flaps on each side. 



" $. Clasper with patch of modified scales on outer side ; 

 penis-sheath armed at end with one or two long tapering 

 processes which are curved basad." (Roths. & Jord., 1903, 

 p. 35). 



Egg. — Rather small, yellowish -brown or green in colour. 



Larva. — Similar to that of Psilogramma menephron, but the 

 tubercles on the anterior segments, horn, anal flap and clasper s 

 smaller ; colour green with oblique stripes. The larva of 

 M. nyctiphanes has a large fleshy hump on the dorsum of 

 segment 3. 



Pupa. — Tongue-sheath free ; coxal piece, sculpturing on 

 segment 4 and antespiracular ridges present ; colour chestnut. 



Habits. — The food-plants belong to the families Verbenaceae^ 

 and Laurineae. Pupation takes place in a cell underground, 

 except in the case of nyctiphanes. 



Hab. Oriental Region. Three Indian species and sub- 

 species.
