A NEW ORYSSID FROM CHATHAM ISLANDS, BISMARCK 

 ARCHIPELAGO. 



BY WILLIAM H. ASHMEAD, A. M., ASSISTANT CURATOR, U. S. NATIONAL MUSEUM. 



In a lot of parasitic Hymenoptera, sent to me by Prof. T. D. Alfken, of the 

 Stadtisches museum fiir natur-volker-und handelskunde, Bremen, Germany, 

 was a single male specimen of an oryssid, collected in 1899 by Dr. Hugo H. 

 Schauinsland, in the Chatham Islands, east of New Zealand. 



It is an interesting form belonging to a genus not yet known to occur on these 

 Islands, the only other species known from these regions being from Aru. 



Ophrvnopus schauinslandi, sp. nov. 



(J. — -Length 6.6 mm. Black, the head rugose-punctate with an aeneous black tinge, the 

 forehead tuberculate, the face with two carinae that diverge anteriorly and are connected 

 with a transverse carina bounding the front margin; thorax sliagreened ; legs wholly black, 

 the hind tibiae serrate on outer face, armed with about 11 teeth ; the first three being very 

 minute. 



The wings are hyaline, with the apical third or more of the front wings fuscous, the 

 stigma and veins being black or brown-black. 



The abdomen is as in Oryssus, black and shining, but with the first four or five seg- 

 ments above more or less shagreened and faintly, sparsely, microscopically punctate. 



Type in Bremen Museum, 



The species is dedicated to Dr. Hugo H. Schauinsland, the Director of the 

 Museum. 



1 These genera probably represent males in genera at present known only from the females, and I therefore do not 

 name them.
