L72 (JVPSV AND T>K< )\VN-TAIL MOTHS. [Jan. 



All told, there were received during 1907 from our European 

 agents, according to Mr. Fiske's notes, as follows: brown-tail 

 moth, - - webs, 111,473; larvae and pupae, 154,760; egg masses, 

 L'7,041; gypsy moth, -- small larvae, 48,000; large larvae and 

 pupa>, 143,950; egg masses, 262. Predaceous beetles were re- 

 ceived as follows: C'.ilosoma sycophant" and imjuisitor, 1,911; 

 Carol us violaceus, 54; C. auratus, 600. 



From the various forms of the gypsy and brown-tail moths 

 imported there were obtained 485 specimens of Pimpla instiga- 

 tor and examinator, of which 251 were released in 1 colony; 

 Apanteles vimincloniin, 995 obtained, 410 released, 3 colonies; 

 A. fulvipes, 3,065 (dead) ; Meteorus sp., 433 obtained, 33 re- 

 leased, 1 colony; Pteromalus egregius and nidulans, 40,300 re- 

 leased, 7 colonies; Telenomus sp. 5,000 (estimated) obtained, 

 4,560 released, 4 colonies; Trichogramma, 11,600 released, 5 

 colonies; Calosoma sycoplianta and inquisitor, 1,911 obtained, 

 578 released, 4 colonies. The very obvious discrepancy between 

 the number of parasites obtained and the number released is 

 principally due to the fact that a large percentage of the para- 

 sites died en route. With certain of the large forms, in which 

 the males predominated, only mated pairs or fertilized females 

 were released. Of the Tachinid parasites, we now have on 

 hand in hibernation upwards of 15,000 puparia. The list of 

 parasites bred from imported material during the' year, as far 

 as determined, has been furnished by Dr. Howard, as fol- 

 lows :
