III -f IV or two s. suj)rasfi(jiii(des, perhaps s. dorsolateralis is united 

 with I or III, V is doubled with a secondary seta = s. prostifj- 

 nia/is, nioreover a secondary seta over the wing-rudinient ; two 

 s. basales^ s. pedalis. 



Stenoptilia pelidodactyla Steiii (1. c. fig. 10) agrees with it in 

 so far as I + II together form a verruca, as also do III and IV. 

 There is moreover a secondary verruca over the wing-rudinient. 



I do not imderstand why we are to accept a doubling for V 

 and a consolidation for I + II. 



In both cases there are two setae in the place where usually 

 there is one; if one couple is interpreted as a consolidation, 

 the same ought to be done for the other. 



Family Thtjrididae. 



The place of this family seems to be very uncertain. Packard 

 considered it in 1895 as a very primitive side-branch of the 

 Neolepidopfera far from the Bombycina (p. 83) biit in 1905 (p. 46) 

 he could derive the Notodontidae directly from them. 



Sharp places it (1901, II) between the Megalopygidae, and the 

 Lasiocampidae which last group he sharply separates from the 

 Boinhyces, whilst Fracker (1915) ranges it between the Liparidae 

 and the Notodontidae. Handlirsch thinks that its place is just in 

 front of Hesperidae and Papilionidae s. 1. together with the Fym- 

 lidae, Pterophoridae and Orneonidae. 



This short account which might be enlarged a great dea'1, shows 

 at least that the family has a rather primitive character. 



In the coll. Kall. is a beautiful, fuU-grown specimen of T/ty- 

 ris fenestrella of which the drawing is to be found on PI. XIII, 

 fig. 11, 12, 13.
