59. OviPosiTsoN OF IscHioGONUs PALLiATUs (Blackburn). 



A lot of three females and males were bred from a larva 

 of FJagithmysus ■pulverulent us under the bark of Acacia 

 l-oa from Oahu brought in by Mr. Swezey. These emerged 

 about June 15, and were fed and seen to mate and were placed 

 with a branch of Euphorhia containing larvae of N eoclytarlus 

 iind on July 7 four males and three females had emerged. 

 These were placed with material containing larvae of Neocly- 

 tarlus. A female was seen ovipositing July 8, the oviposition 

 being similar to that of Heterospilus prosopidis, the ovipo- 

 sitor being grasped by the apical two-thirds of the sheaths, 

 the bases of the sheaths and ovipositor being widely separated. 

 The sheaths are strongly bent and served to brace the ovi- 

 positor while in operation. The oviposition was nearly com- 

 plete when noticed and no details further were observed. 



This species has been recorded l)v Dr. Perkins as attack- 

 ing the Plagithmysine beetles in the native forests. My , ob- 

 servations show that these attacks are responsible for a very 

 lieavy mortality among them, particularly in the case of species 

 ^ittacking thin-barked trees. 



30. Myrmosula Bradley. 



j\fy)mosa parvula Fox and M. rufiventris Blake were 

 originally included. The former may be considered the 

 type. Probably the group is better considered as generic.
