broad quadridentate one near the apex, the apical denticles of which 
are smaller. Hind tibiae reddish at the base ; first joint of all the 
tarsi whitish, the second brown and the rest piceus. Wings hyaline, 
the marginal vein two-thirds as long as the submarginal and four 
times as long as the stigmal. Postmarginal fully as long as the 
marginal. 
Described from one specimen collected by Mr. Schaeffer at 
Brownsville, Texas. 
This is the first species of Chalcedectes to be discovered out- 
side of the South American fauna. 
There is also a male of a second species from Brownsville, 
but is is too poorly preserved for description. 
FAMILY ENCYRTID^. 
Anastatus laticeps sp. nov. 
Female, Length 4.5 mm. Eufo-ferruginous varied with black. 
Entire body clothed with sparse glistening pubescence. Head flat, 
nearly four times as wide as thick ; viewed from in front the eyes 
reach distinctly below the middle, being two-thirds as long as the 
head-height ; above the eyes are close together so that the lateral 
ocelli are nearer to the eye-margin than to the median ocellus. Cheeks 
long, malar furrow distinct, eyes distinctly hairy. Antennae long and 
slender, the scape pale rufous, black at tip and reaching to the anterior 
ocellus. Flag-ellum imperceptibly thickened apically, black, twice as 
long as the scape ; pedicel and first flagellar joint nearly equal ; second 
a little longer, following decreasing in length until the ones near the 
tip are nearly quadrate. Surface of head microscopically rugulose, 
with a metallic reflection in certain lights. Front very slightly and 
broadly excavated. Antennte inserted just below the base of the eyes. 
Palpi blackish toward the tip, the apical joint slender, rounded at the 
tip. Prothorax very short. Mesonotum with the parapsidal depres- 
sions meeting behind the middle and continuing as a median de- 
pression to the hind margin ; the elevations sharp on the posterior 
third, then becoming very weak and broadly rounded; Scutellum very 
strongly convex, almost pyramidal anteriorly, with a wide base on 
the mesonotum, clothed with a few scattered black hairs and bearing
