tlie Early Stages o/' Pultostoimi scliiiieri. 190 



larvce and pup ce described as those of Kelloggiua buruardi do 

 really belong to that species. 



This being established, one may return to the affinities o£ 

 the Paltostoma-lcirva. with the Kelloggina-la,rva. They agree 

 in the form of the antennae, the disposition of the branchial 

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

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

 the sixth segment. But the Kelloggina-\a,Yva. has no spines 

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

 margins. In the possession of spines, the Paltosto7)ia-\arva 

 approaches Curupira. 



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 arranged 

 in tufts, the filaments as seen under a high power (in Palto- 

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

 point, but from a number 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. Wiiile 

 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. Miilier as Curupira 

 torrentium ^ is not widely removed from that of Paltostoma, 

 the Paltostoma-\a.vvvi being intermediate between it and 

 Kelloggina. 



The writer is at a loss to explain the apparent relationsiiip 

 of the Kelloggina-lsiVVdL with that of Blephurocera fasciata. 

 As he has not seen the larva of any sj)ecies of the genus 

 Blephurocera, and as the larvae of species of that genus 

 (according to Bezzi^s tables) difi'er somewhat widely inter se, 

 the question v\ill not be discussed further iiere. 



Affinities of Pupa. — So far as 1 am aware, the only pub- 

 lished reference to a pupa covered with spiniform hairSj like 

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

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

 sent from Brazil among a mixed lot of material. The pupa 

 of Kelloggina 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. oil. pi. vii. fig. tjj shows 

 respiratory horns apparently of much the same form as in 

 Paltostoma schineri. 



* These remarks are made on the assumption that the larva described 

 by Miiller, with only one pair of processes on the sixth seyment, really is 

 Curupira. That he undoubtedly had before him more than one kind ig 

 shown by his pi. iv. fig. 3, which illustrates a very different larva, havinij 

 txoo pairs of processes on the sixth seyment.
