the body of another Homopterous insect, Aphcena sp. 

 (also belonging to the family Fulgoridce). His statement 

 is : — 



" This Aphcena I found at No. b Camp in the Dillrang 

 Valley. When found it had on the hinder part of the 

 back a lot of pure white fluffy stufl*, which I at the time 

 thought was a part of the insect or else a disease. I 

 pinned the Aphcena in the insect box and thought no more 

 about it until the next day, when I proceeded to remove 

 its contents into one of my insect cases. I then found 

 that the white mass had left the body of the AjAcBna, 

 which had died, and was wandering about the box. I left 

 it in the box and it eventually spun a cocoon, which I 

 gave to my friend Mr. Wood-Mason, with a short note 

 which was written at the time on a label underneath the 

 insects." 



Unfortunately the parasite died in the pupa state. It 

 was, however, quite clear that the white material of which 

 the insect had formed itself a case, or at least had covered 

 a case therewith, was the white waxy secretion emitted by 

 the AphcBna and other Uomoptera, and which some- 

 times, as in the Mexican species figured by Burmeister 

 (Genora qu^ed. Insect. Part I. pi. 1), extends in filaments 

 to the length of five or six inches. 



I am further indebted to Mr. Wood-Mason for an 

 opportunity of examining another instance of this Lepi- 

 dopterous parasitism occurring upon a specimen of the 

 small Fulgorideous insect, Euryhrachis spinosa, repre- 

 sented in PI. X. fig. C. 1. We here see a Lepidopterous 

 larva (which appears to me to differ in no other respect 

 than in its smaller size from the larva of Epipyrops 

 anomala) firmly attached by a strong white band of a 

 membranous texture to the dorsum of the abdomen of 

 the Euryhrachis at the base of the third abdominal 

 segment. The specimen being unique, and in spirits, and 

 belonging to the Madras Museum, I have not been able 

 to examine the nature of the connecting cord or band, 

 which is firmly fixed to the underside of the anal ex- 

 tremity of the larva, apparently held by the booklets of the 

 anal prolegs. There seems, indeed, sufficient reason not 

 to suppose that it is the attenuated portion of the mem- 

 branous connection between the second and third seg- 

 ments of the abdomen of the Euryhrachis, as the parasite 

 larva is too large, and as the Euryhrachis is entire so as 

 to prevent the possibility of the larva having been an
