140 OBSERVATIONS ON TINEINA. 



of the suspected novelty, which I v.-as anxious to have figured 

 as soon as possible, lest indeed they should all be spun up 

 before that could be effected. On turning out the sand- 

 cocoons and larv83 on the table, great was my surprise to find 

 one larva which differed from all the others; it was larger, 

 nearly 6 lines long, the others averaging only 4J ; it was 

 whitish-ochreous instead of greenish, and instead of a shining 

 black head, the head was pale brown, with the mouth darker. 

 In short it was evident at a glance that this larva was totally 

 distinct from the others. 



I described it as follows : — Length nearly 6'" ; whitish- 

 ochreous; head pale brow^n, the mouth darker; second seg- 

 ment with a dark brown semi-crescent on each side ; dorsal 

 line slender, reddish-ochreous ; subdorsal lines dark brown, 

 paler in front; spots minute black; anal segment glassy. 



I put this individual larva carefully in a box by itself, and 

 it commenced spinning-up the same day ; on the 27th of April 

 it produced a specimen of Gelechia figulella ! 



I bred three other specimens from the sand-cocoons on the 

 6th, 8th and 10th of April — so that the specimen which ap- 

 peared on the 27tli of that month was exceptionally late, but 

 for which circumstance I should not have had the pleasure 

 of seeing the larva ; the proper time for finding these larvae 

 should be the latter half of January up to the first week in 

 February. 



I am now actually acquainted with the larva of one of the 

 Terrella group, but as yet I do not know it in a feeding state, 

 but the probability seems to me very gi-eat, that it feeds on the 

 Silene Nicceensis. I do not call to mind that there was any 

 moss in the locality where we found these plants. The sand 

 was perfectly loose and shifting. If Gdechia desertella be 

 also attached to one of the Caryophyllacecej it will probably 

 be found to feed on the same Ceraf^tium as the larva of 

 G. marmoi'ea.
