LETTERS FROM DR. STAUDINGER. 137 



time was so much taken up with other things ; and I must admit 

 that I am not learned in the art of hunting for Tinea-larvse, but 

 hope to learn much from you on this subject. My zeal for these 

 interesting creatures is always increasing. Unfortunately, as you 

 know, I cannot make paintings of these larvae, but I have put one 

 of each kind in spirits. These have mostly kept well, so that I am 

 in hopes they will prove quite serviceable for figuring. The mode 

 in which the individual larvae live, on what plant, &c., is probably 

 more important than the larvae themselves. 



" Some of the Tineidae larvae I have found here are perhaps already 

 known, as, for instance, Acrolepia granitella, var. cinerascens, which 

 occurs in the young leaves of Solidago virgaurea [see Acrolepia soli- 

 daginis, pp. 142 & 157], Gracilaria scalariella, Z., in Echium and 

 Cynoglossum, &c. I have already bred several pretty new species 

 of Coleophora, and one species certainly from two very different cases. 

 [See Coleophora spumosella and solenella, pp. 142 & 158.] As I am 

 leaving here so soon, in order that I may do what I can to obtain a 

 knowledge of the entomological productions of this very interesting 

 country, I will get Herr Kalisch, who was my fellow traveller to 

 Iceland, to come here shortly, and he will be able to remain here a 

 longer time." 



"Chiclana, near Cadiz, July 1st, 1858. 



" I have now about 300 species of Tineidae (including therein the 

 Crambidae, Phycidae, and Pterophoridae). You may easily imagine 

 that amongst these are many interesting new things, since before 

 my visit nobody had ever assiduously collected Tineidae here. I 

 have about fifty species ex larva, and of most of these I have the 

 larvae in spirits, or, when possible, prepared larvae. 



" Several of the species do not appear to me referable to any known 

 genus. Unfortunately I became very unwell, owing to the extreme 

 heat which prevails here. Kalisch has been here a month, and has 

 already shown on many occasions his skill in finding larvae. Thus, 

 amongst other things, in cow-dung, which was quite dried by the 

 sun, he has found Tineidae larvae [see Hypsolophus bubulcellus, 

 pp. 141 & 152], also in the roots of a parasitic Orchis. I am now 

 breeding in great numbers a very beautiful little creature, black with 

 silver markings. It feeds on Lavandula stcechas and Thymus, in a case 

 formed of its own excrements, and eats only the parenchyma of the 

 leaves." [See Pancalia Grabowietta, pp. 142 & 157.] 



(In 1866, after my first visit to Cannes and Mentone, I wrote to 

 Dr. Staudinger, " I am now very anxious to see the entire history 

 of your Spanish observations ; that which you gave in the ' Stettin. 

 entomol. Zeitung' for 1859 was only the new species; and your 

 promise to publish ' the entire results of your entomological obser- 

 vations in a special work' still remains unfulfilled." 



To this Dr. Staudinger replied, April 19, 1866, ' At this moment 

 I am not prepared to write anything special on the subject of my 

 Spanish journey, but I will do so by-and-by when I have again 

 been to Spain another time.")
