Again, out of the four on the lower surface, the anterior ends of first, second 

 and fourth were turned towards the margin, while that of the third was 

 turned in the opposite direction. 



The following are short notes regarding five clusters of eggs collected : — 



(1) 23rd May 1906 : — A number of eggs were found laid in two 

 straight rows on opposite sides of a portion of lucerne stem, a few 

 inches above the ground. Only five hatched (after seven days) on 

 May 30th. 



(2) 30th October 1908 : — Forty eggs were found laid in a single 

 straight row on a leaf of Dabh grass {^Imperata arundinacea) at a height 

 of about two feet from the ground. Thirty-three hatched on the 

 same day and the rest did not hatch. 



(3) 2nd November 1909 : — One cluster was found similarly laid on 

 the same kind of grass as (2). These hatched on November 7th after 

 five days. 



(4) 12th August 1911 : — Forty-two eggs were found similarly laid 

 on the same kind of grass as (2) and (3). They hatched after four 

 days on August 16th. 



(5) 6th July 1912 : — Forty-three eggs were found laid in two rows 

 on a leaf of Polyalthia longifolia, at a height of about three feet from 

 the ground. Forty-two hatched after two days on July 8th. 



No parasite was noticed. The eggs, which did not hatch, shrivelled up. 



The larva. — The appearance of the larva is best understood from the 

 figures (see plate, figs. 2 and 3). The young larva is flattened and the 

 measurements of its body and different limbs are as follows : — 



4 m.m. from the tip of jaws to the end of the abdomen ; 



2 m.m. from the head to the end of the abdomen ; 



1-| m.m. from the base to the tip of the jaw in the curved state ; 



1 J m.m. from eye to eye (outside margins) ; 



1 m.m. across the head ; 



1\ m.m. across the middle of the abdomen which is the broadest 

 part of the body and from which it tapers both ways. 

 In shape the jaws take the form of curved hooks bearing teeth on the 

 inner side and they are only movable laterally. The head is square, plate- 

 like in form and the eyes are small groups of shiny ocelli set on a pro- 

 tuberance on the front margin behind the jaws. The antennte are thin, 

 thread-like, and situated between the jaws and the eyes. The prothorax 

 is narrow forming a neck-like junction between the head and the mesotho- 

 rax and allowing free and complete movements of the head vertically and 

 to a small extent laterally. The corners of a fold at the posterior part of 

 prothorax are produced into small spines or pointed tubercles. On each 

 side of the body there are thirteen elongated fleshy spines covered with 

 longish stiff hairs, viz., three on the mesothorax, two on the metathorax 

 and one on each of the eight abdominal segments. The head, body and 

 legs are covered with small stiff' hairs. The colour of the larva, when it 

 hatches out of the egg, is pale yellowish grey, but it soon darkens into dull 

 dark brown. Small patches (some paler and some darker than the general 

 colour) are faintly distinguishable, especially on the head and thorax. The 

 legs are of the same colour as the body. The tarsi possess two distinct 

 joints, the terminal one having a pair of brown claws. 



As the larva grows, it loses its spiny appearance, the spines being- 

 reduced to blunt tubercles ; the surface of the body also loses much of the 

 hairy appearance ; the hairs remain but they are very small. The body 

 becomes plump and a cross section through it would be a triangle with the- 

 three sides more or less curved outwardly, one side forming the back and 

 the other two the sides of the venter.
