tojx)dtt (Marnirocampa). Larvae (Packard 1895, PI. XXIV — 

 XXXV) with setae according to type I, sometimes with a small 

 s. prostiymalis: {Hyparpax aurora, Schizura unicornis). 



It is remarkable that Packard in 1905 (p. 44), while discussing 

 the setal pattern does not figure the .s. prostifftnalis on Schizitra. 



Exceedingly peculiar setae resembling antlers are born by Jfe- 

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

 agree with .*<. dormlut of the prothorax (1. c. PI. XXX). 



7. Sub-family Cerurinae. I^ong stematopoda, setae according to 

 type 1 (Packard 1895. TM. XXXIV— XXXVII). 



Sub-family 3. Pygaerinae, 



Phaiera bucephala Linn. Plate III, fig. 7 — 13. 



Material in alcohol. Collected at Groningen, summer 1915. 



In this caterpillar the head becomes coloured last, while in 

 nearly all others the head is black immediately after moulting 

 and the tubercles become coloured afterwards. 



Instar 1. Duration 9 days. Length 2"j mm. The tubercula 

 are not black. The setae are not plumed. 



Prothorax. V. dorsalit in front of the prothoracic shield, con- 

 sisting of three setae, about */, 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 malts has also three setae of a length of not quite 

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

 has coalesced with the prothoracic shield. 



No 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 in frastig malts, v. basalis with two setae. No 

 s. pedalis and no s. ventralis. 



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

 lateralis, V. suprastig malis and v. infrastigmalis, each of them 

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

 two setae which are not joined together.
