 tpo short to penetrate to any great distance. It is also not 

 in any way a special enemy of the hornfly but apparently 

 attacks any muscoid puparia it encounters. 



26. AspiLOTA KONAE Ashmead. 



This species has been taken in recent years on Oahu only 

 m the mountains ; on Mt. Kaala, in Wailupe, Palolo, Wai- 

 mano and Opaeula valleys by Swezey, and from Mt. Kaala^ 

 Palolo and Kuliouou by Timberlake, 



In January or February, 1914, the tree shells of the 

 genus Achatiiiella were found down on the paths along the 

 Castle trail in large numbers and from them were bred the 

 Sarcophagid Dyscritomyia sp. Fi-om one of the puparia of 

 this fly 5 or 6 Alysiids were bred. In the press of other 

 work at the time this material was probably all lost, but I 

 am inclined to believe that it was this species which emerged. 

 In any case it has so far always been taken in the regions 

 where these flies are found. It would not be surprising if 

 it should prove ^o be an endemic species. 



The varintioii in the uiiinbcr of antenna! joints in the 

 species is most remarkable. I have seen females with. 26 

 joints and others with but 18 while the type was described as 

 having 28 joints. 



27. Table of Some Species of Hawaiian Bracoxidae. 



With the exception of one or two species, the Bra- 

 conidae found in the Hawaiian Islands are immigrant forms 

 brought in by the ordinary operations of commerce or, in 

 some instances, })urposely introduced in the effort to control 

 obnoxious insects. In all about forty species are now known 

 to be established and it is desirable for the use of local Avorkers 

 to have the species tabulated. The wi-iter has recently tabu- 

 lated* the species falling into the sub-family long known as 

 the Braconinae but which through the vicissitudes of type
