34 IN MEMORIAM. 



of the second in September. They feed on Betonica offi- 

 cinalis; turning down the leaves lengthways towards the 

 underside, forming a thin cocoon. The larvae of the second 

 brood winter, however, under a rather thick white cocoon. 

 The perfect insect appears in May and June, and then 

 again in August and the beginning of September, It is not 

 scarce round Frankfort. (1828.) 



BoTYS iNSTiTiALis, Hiibncr, Heyden (E. Z. 1860, p. 

 115). The larva is not scarce on the sands of Mombach, 

 near Mayence, where it was first discovered in 1835 by 

 Herr August Becker, who communicated it to me. It feeds 

 in June gregariously between the leaves o^ Eryngium cam- 

 pestre^ which it spins together to a large, long cone. At the 

 end of June it changes to a pupa in this singly, in a longish,

 or end of July the imago appears, and makes its escape by 

 one of the round holes which the larva had gnawed in the 

 cone. 



Of late the larva has been often found in the same locality 

 by Herr Miihlig, Herr Anton Schmid and myself. 



Herr August Becker also informed me in a letter that in 

 1855 he found the same larva between Paris and Fontaine- 

 bleau. (1836.) 



Ckoreutis Myllerana, Fab. (Mullerana), Heyden 

 (E. Z. 1865, p. 104) ; (Scintillulana, Hiib). I found the 

 larva near Frankfort at the end of August on Scutellaria 

 galericulata, the leaves of which it turns downvt^ards by 

 means of a slicrht web and gnaws from the underside, hence 

 causing large brown spots. 



Professor Fritzsche, of Freiberg, called ray attention to this 

 on an excursion we were making, he having first found the
