38 IN MEMORIAM. 



the privet (Ligustrum vulgare). It quits its domicile the 

 middle of November and spins in any convenient corner an 

 oval, flat, thin, white cocoon, in which it soon assumes the 

 pupa state. 



The imago appears from the beginning to the middle of 

 June of the following year. It is not scarce round Frank- 

 fort, and flies in little swarms by day along the privet 

 hedges. (1825.) 



P.S.— (E. Z. 1862, p. 176.) According to Kaltenbach 

 the larva feeds also in the seeds of the ash. Here I have 

 not met with it in these seeds. 



Coccyx zephyrana, Treitschke, Heyden (E. Z. 1860, 

 p. 117). The larva feeds in June in the root of EryngiiiTn 

 campestre; more rarely it occurs in the stem. At the 

 beginning of July it assumes the pupa state in a thick, grey 

 cocoon, mixed with '^ frass," in the root or in the stem of 

 the plant, and the imago makes its appearance through a 

 hole in the second half of July. 



Not plentiful in the neighbourhood of Frankfort, occur- 

 ring in open places in woods and on the margins of fields 

 behind Biirgel, near Offenbach. (1830.) 



CocHYLis FLAGELLANA,* Duponchcl, Hcydcn (E. Z. 

 1862, p. 173). The larva winters full-fed in the stems of 

 J^ryngium caiwpestrej and the imago appears at the begin- 

 ning of July; the pupa skin remains sticking with its hinder 

 segments in the dead stems. (1847.) 



CoNCHYLis Helveticana, n. sp., Ileyden (E. Z. 1865, 

 p. 100). I found the larva at the beginning of July at St. 



* See p. 39. This is not flagellana, Dup., but a new species Eryn- 

 giana, Heyd.
