case before removal, aud observed that there was a tiny 

 hole, through which the larva could push its head. The 

 imago emeiges through a lid in the upper end. The 

 caterpillar never shifts from the position it has taken up, 

 along the midrib on the under-side of the leaf. Like the 

 preceding and following species it is very irritable. Death 

 takes place about the sixth day, generally a day or so 

 before the fly emerges ; but I have found a caterpillar still 

 alive after the fly had gone. One cocoon produced a 

 number of minute Hymenoptera which are shown together 

 with the case from which they had bored their way. In 

 formalin several of the stung caterpillars are exhibited, 

 each showing the wound caused by the full-grown 

 Hymenopterous larva in its exit. 



[Colonel Bingham has described the Braconid parasite 

 (No. 4) as Microgaster pereJegans (Appendix, p. 126). The 

 minute hyperparasites are shrivelled and indeterminable. 



Two cocoons (one attached to piece of leaf), 1 Braconid 

 and hyperparasites bear the date Feb. 26, 1902. 



One cocoon, 1 Braconid and 5 hyperparasites bear the 

 date Feb. 27, 1902. 



One cocoon, 1 Braconid, 5 hyperparasites, and 1 cater- 

 pillar oi Notodonta, bear the date March 2, 1902. 



Three cocoons and 1 Braconid bear March 11, 1902. 



Four of the cocoons have been opened by pushing off a 

 terminal lid. The lids have been preserved with their 

 respective cocoons in tln-ee examples. The cocoon on the 

 leaf has not been opened by a lid, but bears two minute 

 apertures, one in the side and one near the end. It is 

 probable that the fifteen hyperparasites emerged through 

 these holes. Two cocoons, dated March 11, 1902, had not 

 been opened from within. These two, unlike the others, 

 are strongly marked by longitudinal furrows, and bear the 

 appearance of a distinct cap at one end, clearly marked off 

 from the rest of the cocoon by a circular ridge. They also 

 differ from the other five cocoons in wanting the oblique 

 flattened area towards one end which doubtless marks the 

 base of attachment to the surface of a leaf] 



No. 5. — Host the bee-hawk Hemaris hingi [Ccphonodes 

 kingi, McLeay, of Rothschild and Jordan, Revision, p. 403.] 

 This larva also places the cocoon across the back of the 

 caterpillar immediately in front of the horn. One day I 

 noticed three small caterpillars upon twigs : the next day 

 in passing I found that each carried a case. I then took
