22 IN MEMORIAM. 



Gelechia triparella, Z., Heyden (E. Z., 1860, p* 

 120, E. Z. 1862, p. 176). The very lively larva occurs 

 e\ery where in this neighbourhood in September and October, 

 in serpentine silken galleries betvreen oak leaves fastened one 

 flat upon the other, of which it gnaws the cuticle. The 

 change to the pupa state takes place in the web, and the 

 imago is developed at the end of May or beginning of June 

 of the following year. (1826.) 



I have also found the larvae on oaks as early as the be- 

 ginning of July, but the perfect insects did not make their 

 appearance till the middle of May of the following year. 



Gelechia Rhenanella, n. sp., Heyden (E. Z. 1863, 

 p. 343). 



Alis anterioribus fusco-griseis, squamulis flavidis inter- 

 mixtis, post medium fascia recta flavida. 



Exp. al. 3i'". 



Anterior wings rather short, brown-gi-ey with yellowish 

 scales intermingled ; beyond the middle is a straight yellow 

 fascia, not sharply defined. At the apex of the wing before 

 the cilia are some very small yellowish spots. Cilia dark 

 grey. Posterior wings grey. Head, thorax and abdomen 

 grey-brown. Antennae brownish-yellow, with darker annu- 

 lations. Palpi rather long, yellowish ; beneath black. Legs 

 grey-brown ; tarsi annulated with white. 



It has rather the form of G. basaltinella^ Z., but is only as 

 large us a small G. stipella, H. [nceviferella, Z.]. 



I found the larva, which I have not described, at the be- 

 ginning of July, at Mombach, near Mayence, in hedges, 

 on the lower leaves of Convolvulus sepium, which appeared 

 withered at the tips or at the edges. 



The perfect insect appeared the beginning of August. 

 (1845).
