OBSERVATIONS O^. TINEINA. 135 



CaJamagrostis Egirjejos, in June, would do well to keep 

 a sharp look out for a Rufescens-\\ke larva on that plant. 



Professor Zeller subsequently satisfied himself that the 

 perfect insects of the two species were truly distinct. 



Gelechia Rhomhella. Of the larva of this insect I received 

 a good supply, June 13th, from Jena, where Dr. Schlager 

 finds them very local, to quote his words : ^' I find them 

 only on three apple trees, which present themselves near the 

 village Lichtenhain, at the slope of a mountain." 



These larvae throve very well with me, and I bred a fine 

 series of the perfect insect. The larva I have thus described : 



Length 6 lines : dull dark green, with a whitish line on 

 each side of the back and whitish spiracular line ; the belly 

 is pale greenish-grey ; head dark brown ; second segment 

 above with a black plate divided down the centre. The 

 space between the subdorsal and spiracular lines has more or 

 less of a reddish tinge. The larva feeds between united 

 leaves of apple. 



Gelechia Hithneri, Haworth (Krosmanniella, H.-S.) Of 

 this insect I received larvs from Frankfort, kindly forwarded 

 by Herr Miihlig, and from Hanover, for which I have to 

 thank Herr Glitz. The larva is so similar to that of Gelechia 

 maculea, which occurs at the same time and on the same 

 plant, that I am rather puzzled to know how to separate the 

 two insects when in the larval condition. My description of 

 it is as follows : 



Lengths.! lines : pale green ; head black ; second segment 

 black, at the sides and front edge more of a brown-black 5 

 first pair of legs black; second and third pair of legs green. 

 Feeds, like Tricolorella and Macvlea, between the united 

 shoots of Stellana Holostea ; the larvae reached me on the 

 10th and 25th of May.
