aud the last ou May 15. The llrst egg was deposited ou May 1.'), 10 day* after 

 the first emergence. From the earliest female progeny 3 complete generations 

 were reared and from the latest group 2 generations, the total time consumed 

 by the 3 generations being only 1 day longer than that consumed by the 2. 

 With the hibernating brood this gives a maximum of 4 generations in the year 

 and a minimum of 3 generations. Development was found to cease at about 

 50° F. although oviposition was frequently carried on actively at that tem- 

 perature. This parasite hibernates as a full-grown larva in its cocoon, in 

 which stage it is capable of withstanding a very low temperature. The mor- 

 tality among hibernating larvae during the winter of 1911-12 was very slight, 

 if not nil, in spite of the fact that a temperature of — G° was recorde<l in the 

 iusectary. 



In a study of the alternate hosts the author found that a Enarmonia larva 

 available was parasitized within 2 days, a diminutive male emerging from 

 the cocoon 22 days later. The larvae of neither Euzophera semifuncralis nor 

 Gnorimoschcma gaUacsoUdaginis were parasitized, although the former were 

 left in the cage for several weeks. A codling moth larva containing the inter- 

 nally parasitic larvae of Aficogaster carpocapscd was readily attacked and 

 parasitized by this Calliephialtes and this always resulted in the death of the 

 earlier parasite aud the production of diminutive adult Calliephialtes.

 of recent papers relating to the manner in which the larva of this fly gains 

 entrance to Its host. It appears that the eggs of this fly are in some way 

 attached in clusters of about 16 in number to the basal third of the abdomen of 

 mosquitoes of the genus Janthinosoma. The eggs of the Dermatobia hatch and 

 the larvae find their way into the host while the mosquito is sucking blood.
