152 Psyche [December 
This species traces to B. brevipennis Schiner in Dr. 
Curran’s key. 
Chrysogaster gewgaw n. sp. (Plate 10, Fig. 11) 
A small species obviously related to Chrysogaster shan- 
non i Cur. and to C. neotropica Shannon. Characterized by 
its yellow tibia and basal two tarsal joints and glittering 
greenish silver color with its four copper stripes on the 
thorax. The third antennal joint is shorter than in shannoni, 
the front not so long, besides other differences. The wing 
picture, eye maculation and yellow tibise distinguish it from 
neotropica. 
Male. Length 4 mm. 
Head: eyes actually touching for a very short distance, 
but appear to be contiguous for the length of the vertical 
triangle, or length of second antennal joint. Vertical tri- 
angle considerably elevated, slightly longer than wide. Front 
short, not as long as second joint of antennae, deep coppery 
brown, greatly pitted and rugose. The rugae continue to be 
prominent and transverse on the sides of the shining cop- 
pery face, except that there is a vertical smooth unwrinkled 
band running from below antennae to the base of the oral 
prominence. Oral margin in front produced as a small 
rounded knob, excavated deeply and sharply above; in this 
respect it must resemble shannoni Curran. Eyes marked 
with two vertical bands, looped and folded in a way suggest- 
ing a bow-knot. Occipital rim or margin very narrow, prac- 
tically absent. Cheeks narrow. Antennae light yellow, dark 
brown on the third joint just past arista. Arista pale, ex- 
tremely delicate, basally thickened and reaching just past 
third joint. First joint not half as long as second; second 
and third joint subequal. Pile of face sparse, quite short, 
pale, inconspicuous. Thorax: rich, coppery, finely rugose 
with four prominent dark brown vittse and traces of another 
on each outer margin. Scutellum coppery, finely punctate or 
wrinkled, its rim faintly impressed, its edge rounded but 
slightly squared. Pleurse coppery. Halteres pale brown. 
Abdomen: disk of abdomen dull shining brown. Sides of 
abdomen (and the hypopygium especially so) glittering, 
brassy in color. Legs: all the femora, except their narrow
