the contents of the egg as the contents issued from the wounds made 

 by the ovipositor, and this appears habitual and probably necessary 

 for the continued well-being of the adults. There were probably 

 somewhat more than one hundred adults received in the shipment, 

 and very few emerged from the imported egg-masses after the first 

 day. Several different methods of rearing were tried, but the most 

 successful were in the large jar already mentioned. In this jar adults 

 lived surely for 35 days — a remarkable longevity, indicating that they 

 are probably naturally active and engage in oviposition throughout 

 the egg-laying period of the host. 



_ From Mr. Fiske 's notes, the following are quoted : 



"Ou June 1, parasites placed in the jar. 



"On June 4 they were still very active, and fresh foliage, with beetle eggs, 

 was added. 



"On June 8 another addition of fresh foliage with eggs was made. 

 • "June 11, the parasites, of which the lai'ger part were still alive, were care- 

 fully transferred to a fresh jar, with newly gathered egg-masses. The Tet- 

 rastichus continued active, and were noted ovipositing from day to day. 



"June 18, the parasites were still active, and fresh foliage was added. 



"June 23 the parasites still living were transferred to a fresh jar. There 

 were at least twenty in all. 



"Jime 26, they were still active, and fresh eggs were added. 



"June 29, more fresh eggs were added; a number of the parasites were 

 active and apparently ovipositing. 



"July 1, there was still a small number of the parasites living, and tliese 

 were carefully transferred to a fresh jar. 



"July 5, several were noted still active, but after that date none was 

 observed. 



"Reproduction occurred in all of the jars above mentioned, though in the 

 last it was very scanty. There is no possibility that any of the parasites noted 

 from time to time were other than the originally imported females (the males 

 died very soon after receipt), and the remarkable longevity of the species 

 "may be considered as established. It is reasonable to suppose that they 

 would have lived longer in the open under natural conditions than in con- 

 finement. 



"Very few observations on the larval haliits were made. The first larvae 

 were found on June 9, at which time they were in what appeared to be their 

 second stage. They were, at this time, so small as to be almost invisible to 

 the unassisted eye, and were very active when separated in a drop of water 

 from the surrounding mass of the egg sul)stance in which they were feeding. 

 In this stage they are somewhat remarkable for an armature of minute 

 spines, a row of which borders each of the abdominal segments posteriorly. 

 The last abdominal segment terminates with a somewhat more elaborate 

 arrangement of spines. 



"After reaching this stage their gi'owth is very rapid, and in three or four 

 days more, last-stage larvae were found commonly in egg-masses from several
