dense microscopic thimblelike puncturation, which is finer than that 

 of the head; pleura finely reticulately shagreened, abdomen finely 

 reticulate. 



Eyes bare, the frontovertex and face with sparse, semierect, very 

 fine short setae, the face below the eyes with equally fine appressed 

 whitish pubescence; mesoscutum with rather numerous fine and 

 short, dark-colored setae; the base of the scutellum with a few con- 

 siderably coarser setae and its apex with a pair of long bristles; 

 sides of propodeum moderately densely covered with glistening 

 white appressed pubescence, the metapleura and hind coxae bare, 

 abdomen apparently wholly bare. 



Coloration rather brilliantly metallic; the antennae blackish, but 

 with the club white. 



Male. — Not known. 



CYRTOCORYPHES VIRIDICEPS, new species 



Plate 1, fig. 5 ; plate 2, fig. 19, 19a 



Female. — Head bright metallic emerald green (Ridgway), chang- 

 ing to blue green on the face and cheeks below the eyes ; thorax and 

 abdomen metallic dark violet blue, except the axillae and scutellum, 

 which are matt fuscous or with a metallic sheen only when viewed 

 at a very oblique angle from the side; antennae fuscous, the club 

 white; coxae and hind femora concolorous with the thorax, front 

 and middle femora and all the tibiae fuscous, the spur of middle 

 tibia and the tarsi brownish yellow. Wings with a broad discal band 

 deeply infuscated, reaching from the middle of the submarginal 

 vein to apex of the stigmal, its distal margin strongly rounded, the 

 basal margin squarely truncate; following the discal band is a 

 curved, rather narrow, clear band imperceptibly grading distad 

 into the faintly infuscated area on apical fourth of the disk; some- 

 what less than basal fourth of the wing is hyaline, but with an in- 

 fuscated streak from the base of the submarginal vein along the 

 posterior margin for a short distance; veins brown, but the part of 

 the submarginal vein opposite the hyaline area is nearly trans- 

 parent.
