Mesothorax and metathorax, V. dorsalis and in front of it a 

 verruca, which is not coloured black and bears setae, which 

 are about */<, mm. long. V. suhdorsalis, v. suprastigmalis, v. 2^f'o- 

 stigmalis, v. basalts. 



Abdomen 1 — 9. V. dorsalis, v. subdorsalis, v. suprastigmalis 

 which is placed very low; v. jirostigmalis, ik infrastigmalis; v. ba- 

 salts very large. On the fore-part of the segment v. propedalis 

 is located. The proleg is coloured dark and bears setae of 1 mm. in 

 length. All the abdominal segments bear the same pattern, with 

 the understanding that segm. 1, 2, 7 and 8 bear a v. pedalis 

 as well. 



Segm, 10. The arrangement in my specimens is not very clear. 

 I do not believe that there is a segment 11. 



Instar IV. Length 33 mm. The whole body is now covered 

 with irregularly spread verrucae between which there are also 

 placed setae on the skin. I could not distinguish the primary 

 verrucae. The segment is now divided into four rings. The first 

 three especially bear the verrucae. 



Instar V as IV. 



Recapitulation. The third instar of the caterpillars bears 

 a regular pattern of warts. The setae are not feathered. Between 

 these verrucae are spread shorther setae. The pattern agrees with 

 that of other families. There is no v. dorsolateralis, but we also 

 find V. subdorsalis on the meso- and metathorax. 



In the IVth instar no pattern is discernable. The number 

 of verrucae has increased considerably. The appearance of i\ sub- 

 dorsalis on the mesothorax and metathorax may perhaps be 

 ascribed to the same secondary augmentation of verrucae. An 

 examination of the first two instars may possibly give an expla- 

 nation of this fact. 



Family Endromidae. Fracker (1915) does not describe this family. 



Grote (1896) describes the verrucae as those of Bombyx mori 

 instar /, i. e. type I. 



Packard (1905, p. 40) says that the fullgrown larva of En-
