the characters of the imagines only. Ten species 

 of this genus are given in Gray's catalogue, the 

 adult larva of two of these being known through 

 the excellent figures of Abbot and Smith. 6 These 

 two caterpillars possess the characteristic tapering 

 form in a very marked degree ; one is figured in 

 the attitude so often assumed by our species of 

 Ch&rocampa on the approach of danger, the three 

 front segments being withdrawn into the fourth. 

 (Fig. 34, PL IV., is copied from this Plate). 

 There are no eye-spots either in D. Myron or D. 

 Chcerilus, 7 but only a broad white subdorsal line ; 

 underneath which, and to a certain extent pro- 

 ceeding from it, there are oblique white stripes, 

 precisely similar to those which meet the subdorsal 

 line in the third stage of C. Porcellus?

8 [To this group may also be added Ampelophaga Rubiginosa, 

 Menetrie's, from China and Japan, the caterpillar of which, 

 having the distinct subdorsal line without any trace of eye- 

 spots, is figured by Butler (loc. cit., PI. XCL, Fig. 4). This 

 author also gives a figure of another species belonging to the 

 subfamily Charocampina (PI. XC., Fig. n), viz. Acosmeryx 

 AnceuS) Cram., from Amboina, Java, Silhet, and S. India ; the 

 caterpillar is green, with seven oblique yellow stripes along the 

 sides, and a very conspicuous white subdorsal line with a red 

 border above. As there are no eye-spots, this species may be 

 referred to the present group provisionally, although its general 

 marking is very distinct from that of the Charocampa group.
