with the frons prominent, the antennae strongly clavate, the marginal vein 
very short, the post-marginal and stigmal veins both long. The axillae and 
seutellum are closely fused in Synaspidia as in Chalcaspis and Metaphaeno- 
discus, but both of those genera have the head menisciform. 
Female. Head much wider than long, thick fronto-oceipitally with the 
face strongly inflexed and the frons prominent; in side view, appearing 
distinetly triangular, with the planes of the face and frontovertex about 
equal in length and meeting in a right angle; eyes large, very broadly 
oval, largely dorsal and latero-dorsal in position; frontovertex narrow or 
about four times as long as its narrowest part, the ocelli in an aeute 
angle; face with a large secrobal impression which is subtriangular above; 
cheeks rather short or about one-half as long as the width of the eyes. 
Antennae inserted rather far apart close to the oral margin; scape 
slender, slightly widened at the middle, and reaching a little beyond the 
scrobal impression; pedicel of about normal length and shape, and rather 
longer than one-half of the funicle; flagellum short and strongly clavate, 
the funicle six-jointed and rapidly increasing in width distad, the first 
joint nearly twice as wide as long, the sixth about thrice as wide as long; 
elub broadly oval, about one-half longer again than wide, rather longer 
and much wider than the funicle, three-jointed with the apical joint 
obliquely truncate beneath. Mandibles slender in frontal view, expanding 
at apex and with three acute teeth, of which the middle one is much the 
largest; base of mandible expanded in a plane at right angles with the 
apex. Palpi short, the maxillary pair four-jointed, the labial pair three- 
jointed. 
General form of body short and robust, the thorax about one-third 
longer again than wide, pronotum largely concealed by the head, the collar 
not very strongly arcuate; mesoscutum nearly thrice as wide as long, its 
posterior margin slightly sinuate on each side of the middle; axillae but 
little wider than long, not especially acute at the inner angle and rather 
widely separated medially; they are also closely fused to the seutellum, 
the separating suture being only weakly indicated; the consolidated seu- 
tellum and axillae as a whole is about as long as wide at the base, and 
the apex is well rounded. Abdomen at base as wide as the thorax and 
somewhat shorter, subtriangular in dorsal view with “the apex subtruncate; 
the dorsum rather deeply concave, the venter subvomeriform; vibrissal 
plates situated near the middle of the lateral margins; ovipositor wholly 
enclosed by the ventrites and the sheaths not appreciably protruded. 
Legs short and normal in structure; middle tarsi with the usual taper- 
ing form and considerably stouter than the hind pair. Wings small and 

pulvinate, longer than wide, the apex rather broadly rounded, the sides 
and apex high and declivous. The marginal vein is about three times 
longer than wide; the stigmal short, slender, curved upward, a little over 
one-half the marginal; the postmarginal shorter than the stigmal, being 
short and triangular.
