DESCRIPTIONS OF NEW HYMENOPTERA, NO. 9. 



By J. C. Crawford, 



Associate Curator, Division of Insects, United States National Museum. 



In this paper are included, in addition to the descriptions of new 

 parasites of economic importance, records of some North Dakota 

 bees from O. A. Stevens, a series of specimens having been given to 

 the United States National Museum. All the illustrations, with the 

 exception of those of G. Tiagenowi, were made with a camera lucida. 



Superfamily APOIDEA. 



MELISSODES FOXI, new species. 



Melissodes trifasciata Fox, female, Trans. Amer. Ent. Soc, vol. 18, 1891, p. 347, 



not of Cresson. 

 Melissodes mimica Fox, male, Trans. Amer. Ent. Soc, vol. 18, 1891, p. 347, not 



of Cresson. 



Female. — Length about 10-11 mm. Similar to M. trifasciata 

 Cresson, but the pubescence of head and thorax ochraceous instead 

 of griseous, the plurae with no dark hairs; front and middle tibiae 

 and middle and hind femora, in addition to the tarsi and hind tibiae, 

 fulvous; abdominal hair bands more ochraceous. 



Male. — Length about 8 mm. Similar to the female, but with 

 the clypeus, labrum, and base of mandibles lemon yellow; legs, 

 except coxae and trochanters, fulvous. 



Habitat. — Portland, Jamaica. 



Type.— Cut. No. 18179, U.S.N.M. (female). 



Four males and four females from the Fox collection, three of the 

 males (paratypes) being labeled only "Jamaica." 



In the collections of the United States National Museum are two 

 females from Utuado, Porto Rico, collected in January, 1899, by Mr. 

 August Busck, which, while they have the thorax clothed with grise- 

 ous rather than fulvous pubescence and the abdomen with a metallic 

 luster, are certainly the true M. trifasciata of Cresson, and are the 

 ones used in the comparison made in the above description. 



M. mimica Cresson has, as a reexamination of the type by Mr. E. T. 

 Cresson, jr., shows, the clypeus only, yellow. M. rufodentata Fabri- 

 cino, male, is very similar in general appearance to foxi but the dorsum 

 of the mesonotum is without dark hair.
