embedded the bases of three pure white but not shining, elongate-ovate 

 and subreniform eggs, from which the above three larvae doubtless 

 emerged; they are in no wa)' eaten. — Goodwin adds "The species appears 

 to lay its eggs generally near the head of the host-larva and in numbers 

 varying from one to fifteen or sixteen, but as a rule only three to iivc^ I 

 never find the eggs on larvae less than about three-quarters grown " (?do 

 thev not attack the host till its last skin be cast). — One of these three 

 larvae seemed lu be dead by March 7th, 1904; another had become 

 strongly convex, the lateral lobes being then practically continuous with 

 the rotundity of the body, which is become distinctly fatter towards the 

 head and slightly attenuate anally, as though preparatory to jnipation ; 

 the third is still in the host-larva. — All three unfortunately died, though 

 little doubt can, I think, be entertained that they appertained to the 

 present species; but it is remarkable that none of the three observers note 

 ektoparasitism. 



The following recorded hosts were, perhaps, better gi\en generically, 

 since to the old authors the present species was most vaguely circum- 

 scribed; I omit the smaller Geometers, which are placed under P. gracil- 

 ipi's, and Dicranura vinula since the species bred from the latter is almost 

 certainly P. aphaloles, though attested by Fitch (PZntom. 1880, p. 68) and 

 Bridgman {I.e. 1884, p. 70). Recorded hosts of P. /csfairus are : — Dicra- 

 nura bifida, Clostera anachoreta, Acronyda psi (teste Bridg.-Fitch, f^ntom.
