AET. S SOME NEW CHALCm-FLIES — TIMBERLAKE 31 



Head with sparse, fine, inconspicuous pubescence on the cheeks 

 and frontovertex, the face mostly bare, the eyes with a few erect 

 extremely short setae; mesoscutum sparsely set with fine, pale- 

 colored, seriately arranged setae, the scutellum with a few similar 

 setae on the disk medially, and a pair of longer setae at apex; lateral 

 margins of propodeum with a small patch of white pubescence ; ab- 

 domen with sparse setae, mostly along the sides and at apex, but the 

 basal tergite with a transverse rovr on each side not far from the 

 apical margin. 



General color rather dark aeneous green, the face and cheeks 

 brighter green, with a brilliant golden luster or with a reddish luster 

 at the oral margin and over a greater part of the cheeks ; mesoscutum, 

 apical margin of scutellum in certain aspects, and lateral margins 

 of propodeum light metallic green, the axillae and remainder of 

 scutellum much darker and duller; pleura and sternum of thorax, 

 tegulae, propodeum, and lateral margins of mesoscutum, more or 

 less widely and distinctly, yellowish brown to rather dark brown 

 or even brownish fuscous, the propleura with a metallic luster; 

 abdomen sometimes somewhat bluish black, but usually light green 

 with a bright luster at the base. Antenna brownish yellow, the 

 scape and club palest, the pedicel and funicle more or less em- 

 browned. Legs broAvnish yellow, the apex of middle tibiae, spur, and 

 middle tarsi palest, the hind femora and tibiae much darker or more 

 or less brownish fuscous; a very narrow ring at base of hind tibiae 

 and apex of the same more or less broadly pale; apical joint of all 

 the tarsi fuscous. Brachypterous wing hyaline or whitish, some- 

 times a little infuscated at apex; macropterous wing rather deeply 

 infuscated, but with the basal fourth and a band across the widest 

 part just beyond the apex of the venation hyaline, the band composed 

 of two subtriangular areas opposed at their apices; subbasal infus- 

 cated band extending from just beyond the middle of the submar- 

 ginal vein to slightly beyond the apex of the stigmal vein, both its 

 basal and its apical margin straight and transverse, but the band is 

 somewhat interrupted by a curved subhyaline streak subparallel to 

 the posterior margin and placed about one-fifth of the width of the 

 wing from the margin; veins pale brownish yellow, with the apical 

 half of the submarginal, the marginal, and postmarginal veins 

 darker ; hind wings hyaline.
