ART. 2. ICHNEUMON-FLY GENUS METEORUS MUESEBECK. 41 



The material from which the above host records were taken is 

 in the United States National Museum, and the gipsy-moth parasite 

 laboratory, with the exception of the type of relativus, recorded as a 

 probable parasite of Malacosoma disstria by Viereck in his descrip- 

 tion. Localities represented by this large amount of material include 

 many points in District of Columbia, Missouri, Florida, Massachusetts, 

 North Carolina, Maryland, West Virginia, Indiana, Michigan, New 

 Jersey, Connecticut, Arkansas, New Mexico, Oregon, Nova Scotia. 

 Other specimens, in the collections of Cornell University, the Boston 

 Society of Natural History, of Doctor Brues at Harvard University, 

 and of Mr. Nathan Banks at the Museum of Comparative Zoology^ 

 Cambridge, Massachusetts, are from localities in New York, New 

 Hampshire, Maine, Rhode Island, Virginia, California, Quebec. 



A careful study of the types of hyphantriae, oecopsidis, Jioridanus, 

 and triangularis has led me to regard all as the same species; and Mr. 

 Gahan's notes on the type of relativus, together with the original 

 description, make practically certain the identity of this species 

 with hyphantriae. In his description of relativus Viereck stated that 

 the antennae were 23-segmented. This was midoubtedly a typograph- 

 ical error. Dr. S. J. Hunter of Kansas University has very kindly 

 had the type examined, and writes me that it has 33-segmented 

 antennae. 



SPECIES TRANSFERRED TO THIS GENUS, BUT EITHER UNRECOG- 

 NIZABLE, OR BELONGING ELSEWHERE. 



METEORUS VITTICOLUS (Holmgren). 



Saprotichus vitticollis Holmgren, Eugenies Resa Insect., 1868, p. 431. 

 Meteorus vitticollis Holmgren, Szepligeti, Genera InBectorum, faec. 22, 1904, 

 p. 180. 



Type. — Doubtless in a European collection. 



While the original description is extensive many important char- 

 acters are not discussed, and I have found it impossible to place this 

 species in the key. Quite probably it will fall near trachynotus, 

 which it resembles in having the first and second abscissae of radius 

 about equal, in the prominent mesonotal lobes, and to a considerable 

 degree, in color; however, the long malar space would ally it more 

 closely with terebratus. 



Distribution. — California. 



Host. — Unlmown.
