This bciiii;; t'stal)li>lif(l, one may return to the afliiiitics of 

 the Paltostuma-\n,r\n with the J\e//oi/i/i>ia-\iirvii. They aj^ree 

 in the form of the antenuie, the (lis()()sitiou of tlie branehial 

 filaments in tufts, tlie form of tlie lateral processes (closely 

 similar), and the presence of only one pair of processes on 

 the sixth se^jment. Hut the Kel/of/f/ifia-hdrva has no spines 

 on its dorsal surface, only some weak ones on the lateral 

 marjjins. In the |>ossessiou of spiues, the Paltostomu-\dr\n 

 approaches (Junipira. 



The writer is a little uncertain as to the importance 

 attached to the disposition of the branchial filaments — 

 whether in longitudinal series or tufts. Even when arranjj^ed 

 in tufts, the filaments as seen under a high power (in Pa/to- 

 stoma, at least) do not arise co-basally, i. e. all from one 

 point, but from a numljcr of points. It is easy to imagine 

 the pushing up together of a series to form a tuft, or con- 

 versely the spreading out of a tuft to form a series. While 

 the arrangement provides a useful systematic character, 

 perhaps too much weight should not be attached to it. If 

 this be so, the larva described by F. Miillcr as Curupira 

 torrentium "'^ is not widely removed from that of Pultostoma, 

 the Pa/tosio}na-\a.r\a, being intermediate between it and 

 Kelloyyina. 



The writer is at a loss to explain the apparent relationship 

 of the Kello(/(/iiui-]a.r\'a. with that of Bltphuroctra fasciutu. 

 As he has not seen the larva of any species of the genus 

 BlepharoctrUj and as the larvae of species of that genus 

 (according to liezziN tables) difier somewhat widely inter st^ 

 the cjue>tion will not be discussed further here. 



Affinities of Pupa. — So far as I am aware, the only pub- 

 lished reference to a pupa covered with spinifurm hairs_, like 

 that of Paltostoma, is given by Bezzi in a footnote on p. 30 

 of his work cited ( 1913). He there mentions such a |)upa as 

 sent from Brazil among a mixed lot of material. The j)upa 

 of Ketloy</iiia barnardi is nude, and has the outer laminae of 

 the respiratory horns much more bluntly pointed at the apex. 

 The figure given by Miiller {op. cit. ])1. vii. fig. 6j shows 

 respiratory horns apparently of much the same form as in 

 Paltostoma schineri. 



• These remarks are made on the assuraption that the larva described 

 by Miiller, with o7tlij one pair of processes on the sixth seffvutit, reallv is 

 t'urupira. That he undoubtedly had before him more than one kind ia 

 shown by his pi. iv. tig. 3, which illustrntea a very different larva, havinij
