304 Mr. Poulton's notes in 1886 



five eggs of P. eephalotes attached to it in the following 

 positions : three eggs between the 2nd and 3rd thoracic 

 segments, one of these being close to the median dorsal 

 line and two rather farther down on the left side ; two 

 eggs at the same level as the two last described, between 

 the 3rd thoracic and 1st abdominal segment. They had 

 all just begun to develop before the larva arrived, but 

 were in the first stage. When the larva darkened on 

 the 25th the area to which the parasites were attached 

 remained green. In this instance the larva was unable 

 to protrude its flagella. There was every reason for the 

 belief that the eggs had been attached to the larva 

 before the last stage, and that DeGeer was right in 

 saying that the skin can be changed without removing 

 the eggs. Thus there were ragged remnants of skin 

 round the ova at their points of attachment, and further, 

 one of the prothoracic spiracles contained the main 

 tracheal branch of the last stage, still lying in its lumen, 

 seeming to show the difficulty with which the skin had 

 been thrown off owing to the fact that it was pinned 

 down, as it were, by the ova, so that ecdysis was only 

 accomplished after the old skin had been torn to a 

 considerable extent. There were minute scars near the 

 ova, as if others had been attached to the larva, but had 

 been torn out in ecdysis, or they may have been due to 

 ineffectual attempts at oviposition on the part of the 

 female Paniscus. In this case also all the ova were 

 removed except one. 



(3). On August 22nd I found another adult larva near 

 Oxford, and to it only three ova were attached : one 

 ovum between the 2nd and 3rd thoracic segments just 

 below the white margin of the purple band ; two ova 

 between the 3rd thoracic and 1st abdominal segment, 

 close together and in the same position. These latter 

 ova were removed. The larva was unable to make use 

 of its flagella. On August 25th the larva was about 

 full-grown, and the parasites had just begun to develop. 



On September 3rd larva (2) was examined, and the 

 parasite was seen to have grown immensely, being far 

 larger than any obtained last year. Its posterior 

 extremity was detached from the egg-shell, and it was 

 still eating the larva, although the latter was much 

 shrivelled and was dead (recently). The Paniscus was 

 very distended and glistening, being thus quite different
