CARL VON HEYDEN. 39 



Moritz and Pontresina in the capsules of Genilana acaulis, 

 of which it devours the seed. I took many specimens with 

 me to Frankfort, but they died. Afterwards I found one 

 dead Tortrix in the box. 



My C. Helveticana^ of which I can give no sufficient 

 diagnosis, agrees very well with Herrich-SchafFer's Flagel- 

 lanaj fig. 95, both in size and colouring. 



I believe that amongst C. sanguinana, Tr., Flagellana, 

 Dup., and Fra^ic'/llana, F., there are still different species, 

 very closely allied, to be distinguished. It is probable that the 

 larvae and their different habits may help us in this respect. 



C. sanguinana, Tr. {Baumanniana, Hb.), is sufficiently 

 distinguished by the broad red fascia from the allied species ; 

 its larva feeds in the stems of Eryngium campestre. 



The larva which I have described as that of C.Flagellana, 

 Dup. (E. Z. 1862, p. 173), is not that species. It feeds, like 

 that of C. sanguinana, in the stems of Eryngium campestre. 

 It is considerably larger than Flagellana, Dup. Possibly 

 Herrich-Schaffer's Flagellana, fig. 345, may belong to it, 

 but in my numerous specimens, the first fascia is always in- 

 terrupted towards the costa. I now name my species 

 C, Eryngiana. 



The C. Francillana, F. (Wood, fig. 1152), to which the 

 Flagellana of Duponchel probably belongs, feeds in the 

 larva state on the seeds of Daucus Carota. 



C. dilucidana, Steph., Wilkinson, which is also a closely 

 allied species, feeds in the larva state on the seeds of Pas- 

 tinaca saliva. 



Tortrix rutilana, Hiibner, Heyden (E.Z. 1861, p. 32). 

 I found the very lazy, hybernated larva at the end of March 

 and beginning of April on juniper, where it lives in a short, 

 tubular cocoon, covered with brown-grey excrement. In
