162 THE ENTOMOLOGIST. 



in its head when annoyed, the anterior part of the body 

 assuming a graceful curve, but more commonly falls from its 

 food-plant, retaining its straight rigid position, in which it 

 exactly resembles a twig of the ling. Head and body about 

 equal in width ; head broadly but very indistinctly notched 

 on the crown : body extremely slender, notwithstanding the 

 presence of a dilated lateral skinfold ; the 12th segment is 

 slightly elevated ; the divisions of the segments are not clearly 

 defined, but each is transversely wrinkled, and divided by 

 the wrinkles into fourteen or sixteen extremely narrow but 

 distinct sections. Colour of the head wainscot-brown, with 

 four longitudinal darker marks, which are continuous with 

 dorsal stripes on the body : body pale wainscot-brown, with 

 a medio-dorsal darker stripe, which increases in intensity at 

 the divisions of the segments, and still more at the anal 

 extremity ; it is traversed throughout by a thread-like paler 

 stripe ; between this medio-dorsal stripe and the spiracles is 

 a rather paler stripe, also intersected by a paler thread-like 

 stripe ; the skinfold is paler than the dorsal area, and below 

 the skinfold is a darker stripe, which becomes more intense 

 towards the anal extremity, and terminates in the ventral 

 claspers ; the ventral area is very pale, except between the 

 ventral and anal claspers ; the spiracles are black, and there 

 is a black dot below the 2nd, 3rd and 4th spiracles ; the feet 

 are very pale; the claspers darker, but having a pale external 

 area. I am indebted to Mr. Birchall for a bountiful supply 

 of this larva, which has not been previously described. Al- 

 though apparently full-grown on the 25th of September, they 

 seem inclined to hybernate. — Edward Newman. 



Life-history and Characters of Aplasia ononaria. — 

 When last at Epping my friend Mr. Doubleday showed me 

 a specimen of Aplasta ononaria, given him by Mr. Pifiard, 

 and taken by that gentleman about the 18th of July, in the 

 Warren at Folkestone, amongst plants of Ononis arvensis. 

 The genus Aplasta was established by Hubuer in 1816, and 

 has been adopted by Herrich-Scha^fler, Lederer and Guenee; 

 it forms part of the genus Fidonia of Duponchel, and of the 

 genus Cabera of Treitschke and Boisduval. Guenee appears 

 to have exercised his usual judgment in retaining it as a dis- 

 tinct genus, since it exhibits no affinity ^with either Fidonia 

 or Cabera, from both of which the larva widely separates it.
