12 RESULTS FROM GIPSY MOTH PARASITE LABORATORY. 



tion of this mass indicated that 181 of the eggs were apparently 

 healthy. Parasites had emerged from 108, while the dead or douhtful 

 eggs numbered 35. Mr. Fiske thinks that the parasites that had 

 emerged were probably Schedms. On December 14 the 35 eggs of 

 the third category were assorted into those which appeared to contain 

 parasites and those which were dead. They were emptied into a 

 watch glass, and a single, small, living parasite (the Perissopterus 

 under consideration) was found. Careful examination of the eggs 

 showed two which had very small round holes in the side, from either 

 of which the parasite might have come. These holes were smaller 

 than those usually made by any of the other known parasites. These 

 eggs were separated from the others, and on March 4 one of them 

 was boiled in caustic potash (KOH) and its contents examined. 

 Fragments of the pupal exuvium of a small Chalcidid different from 

 that of any other parasite studied was found and mounted. There 

 was no other indication of any other parasite in the egg, and the 

 one which emerged appeared to have fed upon the caterpillars pri- 

 marily. No parasite remains were found in the other pierced egg. 

 The parasite found on December 14 was placed in a small vial with 

 a variety of eggs, including some of dispar that contained larvje of 

 Anastatus, others that contained healthy dispar caterpillars, and 

 some of the tussock moth. The Perissopterus (which was a female) 

 lived for some days, but showed no interest in any of the eggs.

 TELENOMUS, new species. 



In the autumn of 1897 there was received from Prof. S. Mokshetsky, 

 of Simferopol, Russia, a single specimen of a new species of Telenomus, 

 which he reared during September, 1906, from the eggs of the gipsy 

 moth. As probably Professor Mokshetsky will describe tliis species 

 himself, it is given no name at this time. Curiously enough, it belongs 

 to the same group of the genus to which Telenomus cultratus Mayr 

 belongs much more closely than to any of the species reared from 

 Lepidopterous eggs. T. cultratus lives both as larva and pupa in 

 the eggs of the Pentatomidee, from which it has been reared by 

 Rogenhofer and Hofmann. This new species does not appear to be 

 an important parasite of dispar eggs, since tliis is the only rearing 

 known to us, and none has been recorded.
