118 THE ENTOMOLOGIST, 



two lots of larvge it would appear they attain full growth sooner or 

 later in different localities, for the larvae from Bristol were spin- 

 ning up when received in the first week in May, and were all pupse 

 when the still smaller larvse arrived from Norwich at quite the 

 end of the month. They were feeding on the under side of the 

 leaves of the burdock, eating through and quite riddlnig the large 

 leaves. Length about three-eighths of an inch, and of moderate 

 bulk in proportion ; the head has the lobes rounded and polished, 

 and is considerably narrower than the 2nd segment ; body rounded 

 at the subdorsal region, slightly flattened dorsally, and still more 

 flattened ventrally ; it is attenuated posteriorly, and also from the 

 3rd segment to the head ; tubercles large and prominent, each of 

 them emitting a tuft of moderately long hairs ; skin very slightly 

 roughened, and the segmental divisions well defined. Ground 

 colour of the head and body uniformly pale pea-green, the 

 mandibles brown ; two rather distinct grey lines extend through 

 the dorsal region, enclosing between them the less distinct, 

 narrow, grey, medio-dorsal line ; there is an indistinct row of 

 grey spots substituting the subdorsal line, and the spiracular 

 ridge is also greenish grey ; hairs grey, those from the side 

 tubercles stand out horizontally and are slightly curved, giving a 

 remote resemblance to the larva oi Acronycta Uporina ; ventral 

 surface uniformly of the pale green of the dorsal area. When 

 full-fed the larva spins a patch of silk on the under side of the 

 leaf, or on the stem of the burdock, or on any convenient object 

 near, and in a few days changes to a pupa. This, though laid flat, 

 is attached to the silk by the anal hooks only, there being no 

 silken belt round the body. Like others in the genus it is some- 

 what similar to that of a butterfly, or an Ephyra ; is about five- 

 eighths of an inch long, and of average proportions; thorax and 

 head rounded above, flattened beneath ; head bluntly rounded off; 

 the lec^- and wing-cases extend half-way down, but are detached 

 from the abdomen. Ground colour bright green; two distinct 

 white stripes extend from the thorax to the tip of the abdomen, 

 and outside these stripes, on each side of the first two abdominal 

 segments, are two conspicuous black spots, one on each side, and 

 there is a faint indication of similar spots also on the other 

 segments : as in the larva each tubercle emits a tuft of grey hairs.
