176 LEPIDOPTEKA (MOTHS). 



duoing Bombyces. Others are found in a cell of earth. There 

 are three noticealde types of larvae, one seen in most groups, 

 such as the Hawk -moths, Noctuse, &c., in which the larvse 

 have six true legs in front and four pairs of fleshy prolegs 

 behind, with an anal pair posteriorly. The second type is 

 seen in the Geometers or Loopers, in which only one pair 

 of prolegs exist in the middle of the body. The third is 

 seen in the Plusiadse or Y-]\Ioths (fig. 51). The five more 

 important divisions of Heterocera are — 



The Sphinijina, Bomhjicina, Noctuiiia, Geometrina, axAMicro- 

 lejiidoptera. The last three contain the majority of the injuri- 

 ous species. 



The SpMiKjiiia are the Hawk-moths {Sphinijidai) and the 

 Clearwiug-moths {Se-dadui or ^Etjeriidie). They are provided 

 with a long proboscis and usually pointed abdomen, which 

 may (in the Sesiadm) end in a fan-shaped mass of hairs. The 

 antennas taper to a point at the end. The larvfe of the Hawks 

 have a curious horn on the last segment, and live upon the 

 leaves of various plants. The Eyed-hawk (Smeriiithus ocellatun) 

 may be taken as an example. 



The larvas of the Clearwings are all creamy-white in colour, 

 and live by Ijurrowing into the stems of shrubs and trees. 



T/te Currant CJeavtcinij {^^</eria tipuUformis). 



This pretty little moth (fig. 78) is often very injurious in 

 black-currant plantations. The Clearwings 

 (^Ei/eriidtji) take their name from the fact 

 that the major area of their wings is trans- 

 parent. This species is a little more than 

 two-thirds of an inch in expanse of wing;

a black fringe to the wings, a black bal
