PARASITIC HYMENOPTERA FROM CAPE COLONY. 
107 
GONATOPUS SIMILIS Sp. nOV. 
Female. Length 3 mm. Brownish-yellow, the head darkened 
on the front ; the abdomen piceotis and the antennae black, except 
base and tip. Head deeply excavated behind, and above the 
antennae ; brownish-yellow, blackened above the ocelli. Front 
with a median raised line from the anterior ocellus to the base of 
the antennae ; smooth and shining, shagreened toward the vertex, 
on the occiput, and on the sides of the face below. Lower orbits 
not hairy or pubescent. Clypeus strongly and evenly rounded 
anteriorly. Maudibles 4-dentate. Eyes bare ; antennae short, but 
not thickened, the scape slender, arcuate, one and one-half times 
the length of the pedicel ; first flagellar joint about the length of 
the scape; second equal to the pedicel; following joints about 
two times as long as thick, gradually shortening except the last 
which is nearly twice the length of the penultimate. Scape and 
pedicel yellow, flagellar joints one to six black, seven piceous and 
eight yellow. Thorax bilobed, yellowish-brown. The prothorax 
with a transverse impression just before the middle and a narrow 
raised anterior margin. Pronotum finely microscopically 
punctured in front and shagreened behind the impression. Stalk 
of posterior lobe short ; metathorax shining centrally, micros- 
copically rugulose anteriorly and irregularly transversely acicu- 
lated posteriorly ; not toothed at the sides anteriorly. Abdomen 
short, sub-triangular ; piceous black, shining, clothed with short 
sparse pale hairs. Legs rather short, pale yellow, the swollen 
portions of the anterior femora and- tibiae brownish. Anterior 
trochanters long, with a rather long stalk-like basal portion. 
Femora swollen on almost the entire basal half. First joint of 
anterior tarsus a trifle longer than the fourth. Second and third 
about equal, together two-thirds the length of the fourth. Chelar 
claw slender, curved only at the tip ; tip of chela reaching to the 
base of the third joint. 
One specimen from Algoa Bay, Capland, May 25, 1898.

This species resembles the preceding rather closely except in 
color. The flagellum of the antennae is not so slender basally, how- 
ever, the apical joint is longer, and the thoracic sculpture some- 
what different. The body and legs also lack the whitish hairs 
which are conspicuous in G. varipes. 
Both forms are exceedingly ant-like, and strongly recall 
species of the cosmopolitan myrmicine genus Pheidole.
