138 OBSERVATIONS ON TINEINA. 



there is a certain amount of artificial gardenings but many 

 of the natural productions of the soil grow unheeded, and 

 perhaps a little more luxuriantly than if on the perfectly un- 

 cultivated ground; the plants o^ Huta growing here had, 

 certainly, a more sturdy aspect, than those I had previously 

 met with; and here I found the larvae of J), rutana. 



They were very easy to find — drawing together a fevf 

 leaves of the plant, with a slight amount of web, after the 

 manner of the genus ; I looked carefully over every plant 

 of JRuta I could find in this sequestered nook, and collected 

 about thirty larvfe; the perfect insects made their appear- 

 ance from the 4th to the 16th of May. 



The larva I have thus described : 



Young larva. Length 1^'; yellowish-green ; head black ; 

 2nd segment reddish-brown black; anterior legs black. 



Larvaj two-thirds grown. Length 6^" ; green; dorsal 

 vessel shghtly darker; spots small, black, placed in pale 

 green rings ; head black ; anterior edge of the 2nd segment 

 reddish-brown, posteriorly with two large black lunate plates, 

 scarcely divided in the centi-e, anal segment pale green ; an- 

 terior legs yellowish. 



Adult larva. Length 9'"; this had faint indications of 

 darker green subdorsal lines. 



Gelechia pingui?ieUa, Trcitschke (see E. A. 1865, p. 129). 

 On the 15th of June last I received some larvae of this species 

 from Mr. Bond, with the intimation that they were taken 

 from the tree which furnished the perfect insects in 1865. 

 The larva3 were just in the act of spinning when they reached 

 me, but 1 made the following description: — Length oh'" y 

 pale green, with a faint rosy tinge on the back, leaving the 

 dorsal and subdorsal lines paler ; head black ; 2nd segment 

 with a black lunate mark on each side; spots small, blackislj. 



I believe it still a disputed point on what the larva feeds;
