OBSERVATIONS ON TINEINA. 139 



all accounts seem to agree that tlie full-fed larvce are found 

 gregariously under the hark of poplar trees. Frey states that 

 according to Schmid the larva feeds on the leaves of the 

 poplar trees ; according to the observations of the late Herr 

 Grabow the larva feeds on the ??io.<?5 growing on the trunks of 

 poplar trees. Let us hope that Mr. Bond will next year 

 ascertain where the larva is, and what it is doing, about the 

 second week in May. 



^GelechiafguMa, Staudinger (Ent. Zeit. 1859, p. 242). 

 As my friend Professor Zeller is still perplexed as to the spe- 

 cific distinctness of G. terrella. and G, desertelln, it must be a 

 source of great satisfaction to him to learn that Staudinger s 

 figulella comes between the two, but has a reddish tinge, 

 which we do not perceive in either G. terrellaov G. desertella. 

 It will be remembered that I bred a specimen of G. desertella 

 from a firm sand-cocoon accidentally picked amongst some 

 moss on the sand-hills near Bidefordin May, 1865 (see Ent. 

 Mo. Mag. vol. iii. p. 57); but in reference to G. figulella, my 

 information goes further, and I have actually described the 

 larva. 



On the afternoon of the 28t;h of February, M. Milliere 

 conducted me to a sandy wood near the sea, on the east side of 

 Cannes ; thence we emerged on to some sand-hills on which 

 grew plants of Silene Nicceensis. These had been terribly 

 eaten by some larva?, the young shoots being often eaten quite 

 level with the surface of the sand ; we sat down beside them 

 and began to poke away the sand from about the stems of these 

 plants; in so doing we dislodged a number of larv£e, with 

 similar habits to those of G. marmoreay and a number of firm 

 sand-cocoons, quite similar to those of G. inarmorea. In- 

 deed I believe the bulk of the larvae and pupa? we thus 

 collected belong to a new species closely allied to G, mar- 

 •morea. 



The following morning I rose early to describe the larva
