Body large, robust ; head as broad as thorax, deflexed ; ver- 
tex broad, more or less cleft in front; genal cones entirely 
wanting; frons not covered by genae, but visible as a narrow 
sclerite from front ocellus to clypeus; front ocellus above; 
antennae short, about as long as width of head. Thorax large; 
pronotum very short. Forewings large, hyaline, transparent, 
acute at apex ; pterostigma unusually large, elliptical; marginal 
cells very large; branching of veins similar in type to Carsi- 
dara. 
Type of genus: Macrohomotoma gladiatum Kuwayama (loc. 
cit., p. 180). 
The genus shows a distinct relationship to Carsidarinae, 
although the head is not so deeply cleft in front and there is 
no basal spur on the hind tibiae, as there is in many of the 
other genera placed in this subfamily (Crawford—Pomona 
Journ, Ent., III; p: 381, 1911).

Length of body (male) 2.9 mm.; (female) 3.3 mm.; length of fore- 
wing 5.2 to 56 mm. General color reddish brown to chocolate 
brown; dorsal portion of scutellum and posterior part of dorsulum, 
vertex, male genitalia, and legs, lighter brown to ochraceous; venter 
of abdomen whitish. 
Head very broad, as broad as thorax, greatly deflexed; vertex 
nearly twice as broad as long, coarsely punctate, with a deep fovea 
on each side of median line posteriorly and a deep sulcus connecting 
them; front margin somewhat cleft, but not as much as in Carsidara; 
front ocellus easily visible from above. Genal cones entirely want- 
ing; frons narrowly visible between genae. Antennae slender, about 
as long as width of head, black at tip. 
Thorax very large, broad and strongly arched; pronotum very 
short, sometimes mostly concealed behind posterior margin of head; _ 
dorsulum longer than broad; metanotum produced at posterior end
