VII r. Fou/r New Species and a New Genus of j^cirasitic 

 Hymenoptera (Ichneumonidas, suh-fam. Opbioninaa) 

 from the Hawaiian Islands. By Robert Cyril 

 Laytok Perkins, B.A. Commiaiicated by Dr. 

 David Sharp, M.A., F.R.S. 



[Read March 5th, 1902.] 



The three new species oi Enicosinlus, Curt., as well as the 

 more interesting form for which the genus Abanehogastra 

 is created, are all found in the Koolau range of raountains 

 on Oahu. The latter with the neuration of Banchogastra, 

 Ashm., combines the cephalic and abdominal characters of 

 many species of Enicospilus. It is probably a rare, and 

 certainly a very inconspicuous species, several journeys to 

 the locality where the iirst specimen, a $ , was obtained 

 having resulted in the capture of a single example of the 

 other sex. Most of the Hawaiian Ophionines fly freely in 

 the day-time as well as at night, and, made conspicuous by 

 their activity, are more easily collected than many other 

 native insects. 



Abanehogastra, gen. nov. 



Eyes large, toucliiiig the base of mandibles or nearly, distinctly 

 emarginate on a line with insertion of the antennae ; ocelli large, the 

 lateral ones touching the eye-margins, but distinctly separated from 

 one another. Propodeum without a transverse carina. Claws of 

 tarsi pectinate. Neuration almost as in Banche^adra, Ashm., the 

 first recurrent nervure interstitial with the second transverse median 

 nervure ; transverse median nervure in hindwings obtusely angularly 

 broken about the middle ; discocubital nervure very regularly 

 curved. Abdomen and legs as in most Hawaiian Enicospilus. 



Abanehogastra dehilis, sp. nov. 



(^ $ . Length 8-9 m.m. Black ; face yellow, with a median 

 longitudinal band in the $ testaceous ; palpi pale, teeth of mandibles 

 black, posterior orbits yellow in both sexes, and the space between 

 the ocelli of the same colour in the $ , black in the $ . Thorax
