IN MEMORIAM. 



Gnophos glaucinaria, Hiibner, Heyden (E. Z. 1862, 

 p. 171). I found the larva of this Geometra, previously only 

 found in the Alps, in vineyards at Riidesheim on the Rhine, 

 on Sediwi albuin, the middle of April, 1860. It was very 

 lazy, and when sitting upright would frequently, when 

 touched, make a tremulous movement with the anterior 

 segments. In my breeding-cage, it sat throughout the fol- 

 lowing winter on its food-plant without eating. In the 

 beginning of April, 1861 (thus after nearly a year), it 

 moulted, and again began to eat, and by the beginning of 

 June had doubled its size, when it spun a thin white cocoon, 

 and changed to the pupa state. 



The perfect insect appeared at the end of June, and showed 

 no difference from specimens from the Swiss Alps. 



Some years previously I found similar larvse at the same 

 place, but they died. 



The discovery of the locality for a species only previously 

 found in the Alps is interesting. (1861.) 



Herminia modestalis, n. sp., Heyden (E. Z. 1865, p. 

 375). 



Palporum articulus ultimus secundo duplo brevior et au- 

 gustior ; alis unicoloribus cinereis, subtilissime obscum 

 squamulatis. 



Exp. al. 13—14 lin. 



This species somewhat resembles S. tentaculalis, L., both 

 in form and size, but the wings are rather narrower; the 

 antennae are shorter, as are also their pectinations ; the palpi 

 likewise are shorter, compressed, dark grey ; the second joint 

 is furnished with a specially strong brush beneath ; the ter- 

 minal joint is half as long, narrow, pointed, but little directed 

 upwards. 



Wings unicolorous ashy-grey, irrorated with very small 

 darker scales, which when highly magnified form wavy lines. 

 From the more numerous scales, the costa of the anterior
