no. 1857. NEW SPECIES OF WASPS— ROHWER. 555 



finely and sparsely so, antennas subclavate, third joint slightly longer 

 than the two following; thorax with the punctures rather more sepa- 

 rated than those of the front ; suture between mesonotum and scutel- 

 lum foveolate; metanotum rounded, the perpendicular face nearly 

 impunctate; posterior face of the propodeum with a median furrow; 

 abdomen longer than the head and thorax, first segment long, 

 about one-third longer than the apical width, length and width of 

 second segment subequal; dorsal surface with distinct separate 

 punctures, becoming smaller apically. Head and thorax (except a 

 broad band between eyes at vertex, a median black line on mesonotum 

 expanding at the ends, and mesopectus, which are black) testaceous; 

 abdomen rufo-testaceous, the first four dorsal segments narrowly 

 banded with white; wings yellowish hyaline, venation basally testace- 

 ous, apically dark brown.

Family MASARID^. 



Genus PSEUDOMASARIS Ashmead. 

 PSEUDOMASARIS COQUILLETTI, new species. 



In color and habitus much like P. edwardsii Cresson. The female 

 may be separated by the presence of a fine raised line on the scutellum, 

 the orbits entirely yellow, and with an interrupted yellow band on 

 the vertex. The male may at once be known from edwardsii by the 

 club of the antennae not being concave beneath. 



Female. — Length 15 mm. Clypeus much wider than long, the 

 apical margin broadly, arcuately emarginate, the surface finely sculp- 

 tured; third antennal joint longer than the fourth and fifth; ocelli 

 nearly in an equilateral triangle ; the postocellar line shorter than the 

 ocellorbital line; thorax finely, closely granular; notauli wanting; 

 angles of propodeum sharp ; transverse cubiti separated on the radius ; 

 abdomen finely, closely granular. Black with abundant yellow mark- 

 ings; the following parts yellow: Mandibles, clypeus except two black 

 lines, labrum, large subtriangular spot above antennae, orbits broadly, 

 an interrupted band on vertex, basal five antennal joints, pronotum 

 except a black line, tegulse, two lines on mesonotum, large spots on 

 mesopleurae, apex of scutellum, metanotum, two spots on metapleurae, 

 propodeum except two large black spots, all the segments of the 

 abdomen broadly (more or less emarginate in the dorsal middle). 

 Legs yellow except coxae, trochanters and base of femora beneath 

 which are black. Wings yellowish-hyaline; venation yellowish. 



Male. — Length 14 mm. Colored like the female except the black 

 on the propodeum and metapleurae is larger, and there is no black on
