Two new Species of Macrophya (Hym.).* 



By S. A. ROHWER, Specialist in Forest Hymenoptera, Bureau 

 of Entomology, Washington, D. C. 



In a recent number of Entomological News (1916, vol. 27, 

 pp. 274-77) Phil Ran has described, in some detail, the dance 

 of a species of Macrophya. Inasmuch as the species was un- 

 described it is desirable that it should be named so that the 

 observation may be catalogued and made available. The spe- 

 cies described as rani is the one referred to in the beginning of 

 Mr. Rau's paper, and the species described as simillima is 

 probably the species recorded as being captured later in the 

 week. From the material at hand it is impossible to make this 

 assertion positive as the individuals are not dated. Both of 

 these species belong to Macrophya in the restricted sense.

This species is closely allied to punctata MacGillivray and 

 propinqua Harrington. From propinqua it may be separated 

 by the spot on the hind tibiae, the mostly black clypeus and 

 labrum, and poorly defined middle f ovea ; from punctata the 

 shape and size of the postocellar area will serve to distinguish 

 it. 



Female : Length 8.5 mm. Anterior margin of the labrum truncate ; 

 the clypeus deeply, arcuately emarginate, lobes broadly rounded apical- 

 ly ; middle and frontal foveae not well denned ; antennal furrows com- 

 plete; front punctured; postocellar area more than twice as wide as 

 long, the sides curved, the surface with rather close, large punctures ; 

 postocellar line one-third shorter than the ocellocular line; vertex, 

 except the posterior part, shining, impunctate ; third antennal joint but 

 little shorter than the fourth and fifth joints; scutum and prescutum 

 shining with separate distinct punctures; scutellum closely punctured; 

 scutellar appendage completely roughened ; mesepisternum striato- 

 punctate; metepimeron normal; third cubital cell subequal in length 

 with the second ; sheath narrow, rounded apically, convex below. 



Black; labrum in the middle, two small spots on the clypeus, an in- 

 conspicuous spot on the mandible, two very small spots on the vertex, 

 the posterior margin of the pronotum narrowly, the anterior margin of
