122 Mr. F, P. Dodd's Notes upon some ronarkahle 



them and observed that after several days the cocoons had 

 dropped off, Tlie parasites appeared in the perfect state 

 on the eighth day, the first caterpiUar dying two days, the 

 second five days and the tljird eight days after the appear- 

 ance of their respective parasites. The third caterpillar 

 seemed dead on the seventh day, but movements v^^ere 

 noticeable in the claspers during this and well into the 

 eighth day. 



It will be noticed that this and the two precedinc- 

 specics of caterpillars must be stung when they are exceed- 

 ingly small, for they are all only about the size of healthy 

 eight- or nine-days- old larvae. 



I had another species of these flies from a common 

 noctuid (AcJi/va sp.). The larva came out under the twelfth 

 or thirteenth segment and affixed its cocoon to the twig, the 

 caterpillar's tail being raised to accommodate it and pressing 

 on and partly around it. In this position the caterpillar 

 remained, though not fastened to the case in any way, it 

 died on the third or fourth day after the appearance of the 

 Hymenopterous imago. 



[This Braconid parasite (No. 5) has been described by 

 Col. Bingham as Microgaster hasalis, viz. the same species 

 as No. 3, also parasitic upon the caterpillar of a hawk-moth 

 (Appendix, p. 125). The single specimen of No. 5 together 

 with its cocoon bears the date Feb. 19, 1902. The cocoon 

 has lost its terminal lid.] 



No. 6, — From the handsome Lyc«nid Ogyris genoveva, 

 Hew. [a synonym of 0. zosine, Hew.] The larvse of this 

 butterfly aie befriended by several species of ants, chiefly by 

 a large Qamponoius, in whose nests they pass the day. 

 When young however they hide under loose bark or in 

 crevices, and can easily be stung by small parasites. The 

 numerous larvse crawl out from under the host and form 

 their lieap of cocoons, the victim dying very slowly. The 

 flies emerge in about seven days, the caterpillars having 

 a little life left in them up to five days later, 



[This Braconid parasite (No, 6) has been described by 

 Col. Bingham as Frotafimiitchs rttfivcntris (Appendix, p. 

 127). Five Braconids, 1 shrivelled Lycii'nid larva, and 7 

 cocoons bear the date March 21, 1902; 5 Braconids and 

 a heap of many cocoons bear Dec. 22, 1902 ; five Braconids 

 and another large heap bear Dec. 23, 1902, The white 

 oval cocoons have been opened by pushing off a terminal 

 lid which in many cases remains attached as it were by a
