" Many hours were spent during the ensuing tew weeks iu searching for these 

 strange calerpiihvrs, wliicli were also t'onnJ uiioii tliree other species of Fuli/orifhe ; 

 some more cocoons, too, were discovered, but throe-fourths of tliese, and of otiiers 

 collected later, produced small jumping ichneumons, six, eight, or eveu twelve 

 emerging from a cocoon, according to its size. Presumabl}' the larvae are stung 

 after leaving their hosts— in all probabilit_v whilst sjiinning, for none of those that I 

 have taken from time to time proved to be victimised ; maybe tiiey are safe under 

 the wings of the hoppers, though, as they ajiproach maturity, they cause sjome 

 displacement of the wings, and though easily seeu may present no weak point 

 to be attacked. 



"The larvae are not rare, but there are only special localities where I ol)tain 

 them ; small shrubs where ants abound are j)roduclive, the hoppers often being 

 numerous in such places, even where the green Oecopliylla ants are. The auts do 

 not fraternise with these Ftdgoridae, like they do with so many species of Jassidue, 

 Fgi/Uidae, etc. ; but they do not molest them, and pass by in scores without seeming 

 to notice their presence. I have seen the green ants traversing branches where 

 there were no less than three species oi Fahjoridae dotted along them. 



" I have never found two larvae of the same size upon a hoi)per, but not 

 infrequently have noticed two of difl'ereut sizes, the second, in every case, being very 

 much smaller than the other, and upon the ojijiosite side. With but few excei)tious, 

 all the larvae I have seen were upon winged insects, the exceptions, as alreiuly 

 stated, being ujmu pupae of the green and the black sjiecies only. I have kept 

 these for many days, supplying succulent shoots regularly to the hosts, until the 

 larvae changed to white, and finally departed to spin. UiKin another page I give 

 particulars of several larvae which I obtained some time ago, two of them when 

 they were exceedingly small, and which I was enabled to carefully observe for 

 many days ; the hosts are still alive, one with a second caterjiillar upon it, but, 

 as the larger portion of my material was despatched five weeks ago, I cannot 

 delay my notes any longer, or would give fuller particulars concerning these. 

 {}\ote. — I kept my notes back for seven weeks, by which time two of the hosts 

 had died, the third dying several days after despatch of notes.) 



" A full-grown caterpillar is in reality a very small creature, with a thick, 

 eveu coating of a waxy-white and light-as-down substance covering the dorsal 

 surface, the sides, and extending well underneath ; it is so thick that the cater- 

 pillar ajipears to be double its real size. This coating parts slightly at the segments 

 when the insect is in motion or curled up, — wheu parted from tiie host, if touched or 

 alarmed, it curls up almost into a ball, and can easily roll from whatever it may be 

 upon, and generally dangles by a thread, and thus suspended bears a strong resem- 

 blance to a round hanging egg-bag of a spider. The head and adjoining segment 

 are (Mily slightly covered with this white matter, liut are drawn closely to the 

 thickly clothed segments, leaving the face alone visible ; wheu the insect is extended 

 the head can be seen. 



" I have collected larvK of various sizes, some being exceedingly small, 

 evidently not long from the egg, and, owing to their colour, scarcely discernible, the 

 lens revealing their presence. Very young specimens arc much the colour of orange 

 pulp. In about ten days this gradually alters to didl purplish red, after which 

 it daily becomes paler until almost colourless; then the skin slowly assumes a 

 whitish hue, as if caused liy a thin deposit, and becomes somewhat distended, 

 and the head is raised a little ; it is now perceived that a moult is about to take
