Observations on the Sources of Hawaiian Encyrtidae 

 (Hymenoptera). 



BY P. 11. TI.MKKKLAKE. 



In 1901 when Ashmead jjiihlishcd liis descriptions of the 

 Hvmenoptera Parasitica of the Hawaiian Islands in the Fauna 

 IFawaiiensis, Vol. 1, Pt. 3, only five species of Encyrtidae^ 

 were known to occur in these Islands. Of these one species 

 was described by Cameron in 188<j from a specimen collected 

 by Blackburn. This species, Eiiryiius insularis, belonging 

 apparently to the new genus Bofhriencyrins,- has not been 

 found since and is presumably an immigrant species that failed 

 to become established. Two other species described as new are 

 apparently endemic and may be known in the future as 

 Eclifhrogonatopus molokaiensis and Nesencyrtus Jraalac, having 

 ix-en wrongly referred by Ashmead to Microferys and Adelen- 

 cyrtus respectively. The fourth species is considered to be the 

 common Encyrtus infclix (Embleton) incorrectly identitied l)y 

 Ashmead as Encyrtus fuscus (Howard) and now known to be 

 iK^arly cosmopolitan. A fifth species not mentioned by Ash- 

 mead was descril)ed in 1898 by Dr. Howard as BJepyrus mars- 

 (li')ii. and which 1 have recently synonymized Avitli Blepyrus 

 mcxicanus Howard . 



In 1907 Mr. Swezey published his observations and figure 

 of a small Encyrtid, under the name of Ageniaspis species, 

 which he found parasitizing the larvae of Odynenis nifjripcimis

1 In the sense used here the Encyrtidae inchide only the griuip known 

 as the Encyrtinae by most modern writers, to tlie exclusion of the 

 Eupelmidae, Signiphoridae and .-Xphclinidae wliicli have heen associated 

 with the Encyrtidae by some authorities. 



- The new genera and species mentionefl will be described in an 

 appendix to this paper.
