topoda (MacrHrondtijXf). Larvae (Packard 1895, PI. XXIV — 

 XXXV) with sotao accoi'dinji; to type I, sometimos witli a sniall 

 .s'. prodüimalis: {Hijparpax aurora, Scinzura unicornis). 



If is remarkable tliat Packard in 1905 (p. 44), wliilo discussing 

 the setal pattern does not figure the s. prostigiualis on Sc]i/ziir(f. 



Exceedingly peculiar setae resembling antlers are born by He- 

 terocampa during instar /, later on they disappear. They seem to 

 agree with 8. dorsalis of the prothorax (1. c. PI. XXX). 



7. Sub-family Cerur'mae. Long stematopoda, setae according to 

 type I (Packard 1895, PI. XXXI V— XXXVII). 



• Sub-family 3. Pijgaerinae.

In this Caterpillar the head becomes coloured last, while in 

 nearly all others the head is black inimediately after moulting 

 and the tubercles become coloured afterwards. 



Instar /. Duration 9 days. Length 2^j^ ram. The tubercula 

 are not black. The setae are not plumed. 



Protiiorax. V. dorsalis in front of the prothoracic shield, con- 

 sisting of three setae, about '^j^ mm. long, they are not united. 



V. suhdorsalis. Three setae which are longer than 1 mm., inplanted 

 on a tuberculum, which is clearly higher than the prothoracic 

 shield. V. suprastig mails has also three setae of a length of not quitc 

 7.2 mm., concentrated on a tuberculum which in most individuals 

 has coalesced with the prothoracic shield. 



Xo s. dorsolateralis, v. poststigmalis with some (mostly 3 or 4) 

 setae, if at least they have not become combined with the pro- 

 thoracic shield, seta infrastigmalis^ v. hasalis with two setae. No 

 s. pedalis and no s. ventralis. 



Mesothorax and metathorax. V. dorsalis with three setae, v. dorso- 

 lateralis, V. suprastigmalis and i\ infrastigmalis, each of them 

 with two setae. V. hasalis is not distinctly outlined, there are 

 two setae which are not joined together.
