138 LETTERS FROM DR. STAUDIFGER. 



" Dresden, March 30th, 1802. 

 " I start for Spain the day after to-morrow." 



" Dresden, October 2nd, 1862. 



" You have probably returned safely home from your journey by 

 this time. I was in Brussels only a few days after you. M. Pologne 

 told me of your visit. 



" My this year's Spanish journey has not proved a very satisfactory 

 one ; yet I have found some interesting creatures, and amongst them 

 two new species of Lithocolletis, both of which are in the larva-state 

 during the winter on Papilionaceous shrubs. I found the living 

 larvae in April on bushes which were still almost covered with snow. 

 One species has the anterior wings entirely yellow, with only a single 

 white basal streak. [See Lithocolletis adenocarpi, pp. 163 & 165.] I 

 believe I have also bred several other new Tineidae." 



"Dresden, August 9th, 1866. 



" Next Monday I think of going for two months to the South of 

 France, to Celles-les-bains, in the Department of Ardeche, there to 

 collect, and especially to seek for the mines of the genera Lithocolletis 

 and Nepticula in September and October." 



" Celles-les-bains, pres de la Voulte, 

 "Dep. Ardeche, Sept. 21st, 1866. 



" Monsieur Milliere has now left me, and I am here all alone, and 

 propose to remain here till the middle of October, perhaps longer, 

 seeking for larvae 



" Unfortunately this season has been everywhere peculiarly un- 

 favourable for Lepidoptera. Amongst the 330 species of Lepidoptera 

 I have found here, there are only about 40 Tineidae ; the cold north- 

 east wind and the heavy rain seemed to have killed them all. To- 

 day I found the first living Nepticula-larvte, so I send them to you 

 at once : viz. six mines in the leaves of a plant [Ehus cotinus] which 

 we grow in gardens at Dresden, and call it ' Perriickenstrauch,' here 

 it grows wild ; also two mines in leaves of Pistacia terebinthus. 

 Probably both larvae belong to the same species, though the plants 

 are so different. On the first-named bush I have found about twenty 

 larvae and over a hundred empty mines, on the Pistacia I have only 

 found three larva?, but I yet hope to find more of both 



" The locality here is quite suited for an entomologist, and there 

 is excellent hunting-ground in three minutes walk from the hotel ; 

 there is very little cultivated ground about here." 



(In my reply to this letter I called Dr. Staudinger's attention to the 

 fact that No. 2228 of his Catalogue, Stathmopoda Guerinii, Stain., 

 had been " eclose d'une grande galle du pistachier, le 15. Septembre, 

 1852," but that I only knew of that one solitary specimen.) 



" Celles-les-bains, pres de la Voulte, 

 " Dep. Ardeche, October 2nd, 1866. 



" Many thanks for your letter and your determinations, especially 

 for the notice respecting Stathmopoda Guerinii, of which I herewith
