16 IN MEMORIAM. 



I hope to be abl^, at a later date, to furnish a description of 

 the larva. (1861.)

SwAMMERDAMiA APiCELLA, Donovan, Heyden (E. Z. 

 1863, p. 107). The larva feeds at the end of June and 

 beginning of July on sloe-bushes which are rather shaded, 

 usually in small societies, in a rather extensive delicate web, 

 devouring the leaves which are still young. It is lively 

 and wriggles about much. 



Under the web it changes to the pupa state in a spindle- 

 shaped white cocoon, with two points at each end; the imago 

 makes its appearance in the following year at the end of 

 April and beginning of May. 



S7V. apicella appears to be a local insect. Years ago I 

 observed the larvae on the hedges of the wilderness at Frank- 

 fort, where it has not been found of late years. On one 

 entomological excursion, which I made with Herr Anton 

 Schmid and Herr Miihlig in 1861, we found them tolerably 

 plentiful in the woods at Eberstadt, near Darmstadt. 

 (1836.) 



RniNosiA HOJiRiDELLA, Kuhlwein, Tr., Heyden (E. Z. 

 1860, p. 119). The larva lives in the middle of June on 

 apple-trees ; about Frankfort it is not abundant. It gnaws 

 under a light web, the upper side of a leaf, which hence 

 becomes rather curved. It forms a boat-shaped, paper-like, 

 white cocoon, from which the imago escapes at the begin- 

 ning of July. (1824.) 



ExAPATE CONGELATELLA, Clerck, Heyden (E. Z. 1865, 

 p. 104). I have bred the male and female moths from two 

 different larvae, which I here describe.
