reddish brown, and the dorsal and subdorsal as well as the 

 spiracular lines were apparent. 



On December 5th, the most developed were seven lines in 

 length, and stretched themselves along the blades of grass when 

 at rest, and were no longer so easily shaken off the food. The 

 claspers on the seventh and eighth segments were by this 

 time fully developed and the spiracles also conspicuous. From 

 this date the larvse gradually increased in size and the final 

 markings became more distinct, till about the middle of January, 

 1884, when several appeared full-fed. Of these the following is 

 the description : — Body, rather stout, cylindrical, smooth, 

 tapering slightly towards each end, but mostly towards the 

 posterior; length, 12 to 13 lines; head, semi-transparent, pale 

 brown, spotted with a darker shade on the cheeks, and with a few 

 scattered fine hairs. Ground colour of body pale-yellowish or 

 reddish brown, closely spotted with darker. Dorsal line paler- 

 edged, with dark brown shading off externally ; the dark edge 

 much intensified at the centre and division of the segments, 

 especially at the latter, so as to give a dotted appearance, much 

 less conspicuous on the three last segments. Sub-dorsal lines 

 paler-edged, with continuous dark brown. Between these lines, 

 on each segment except the two last, is a dark brown spot. The 

 ground colour gradually deepens towards the spiracular line, 

 above which it is rich dark brown, almost black. The sj^iracles 

 have a black circumscription. The spiracular line is con- 

 spicuous, yellowish white in colour, spotted with very pale 

 reddish brown. Below it the ground colour is much paler, so as 

 to show a marked contrast between the upper and under sui-faces. 

 This paler band is succeeded by a similarly spotted darker one, 

 and separated from it by an interrupted dark brown line. The 

 second band is followed by another dark brown one, internal to 

 the insertion of the legs. Claspers ten, the four front ones very 

 sli"htly smaller than the others, but to such an extent as to be 

 scarcely noticeable. 



Up to this date the mortality had been small, only three 

 larvae having died. Between January 20th and February 17th 

 the larvae by degrees disappeared and were supposed to have 

 pupated. The earth was not disturbed till the end of March, 

 when it was carefully examined to remove the cocoons. It was 

 then found that only three of the larvae had gone down, and with
