COLLECTING AT LYNMOUTH, NORTH DEVON. 245 



other hand, the D brood were the slowest growers, and so far 

 have produced only imagines much smaller than either A, B, 

 or C; whilst at this present date (September 17th) seven larvse 

 are still feeding. It will be seen from the following table that 

 twenty-nine imagines from the A larvse emerged from August 

 17th to 23rd, thus completing their metamorphoses in about 

 sixty-two or sixty-three days. I should mention that at the later 

 date (August 23rd) two larvae of brood A were still feeding.

Cidaria sujfumata. — I took several specimens of this species 

 during the latter half of June ; but the capture of a fine and 

 perfect specimen on Jul}' 4th was a great surprise. 



I did not try the attractive power of sugar, so m}' captures in 

 Noctuse were only of such species as I could net at dusk or meet 

 with at rest, and certain others of which I found larvse. The only 

 species in this group worthy of note is Toxocampa craccce, of 

 which I obtained a few larvae from the locality where I took it in 

 1881 and 1882. Vicia sylvatica, the food-plant of this species, 

 occurs sparingly on the rocky cliffs close to Lynmouth on the 

 west side of the river. I also noticed some large patches of the 

 vetch among the brambles in the " Tors," near the Lyndale 

 Hotel, Lynmouth. No signs of larvae having fed on the plant 

 were observed in the latter place, but plants on the cliffs showed 

 evident traces of larval attentions ; and the way in which the 

 leaflets were cleared from the stems was very suggestive of the 

 neat kind of work performed by larvse of I 1 , craccce.
