eral triangle; compound eyes large; a horn-like process at the 
base of each antenna above; antennae except the two basal arti- 
cles opaque; 3 shorter than 4, 9-13 arched. Pronotum polished, 
subangulate posteriorly, with a very few punctures, and becoming 
transversely rugose at anterior upturned collar; ‘pleurae with a 
V-shaped area with large dorso-ventral striae, more distinct for 
anterior half. Scutum of mesothorax with anterior median por- 
tion convex, posterior part flattened, disc with a few coarse con- 
fluent punctures and coarse transverse striae; scutellum sparsely 
punctate with the anterior transverse sulcus carinate, mesopleurae 
polished, with rather sparse shallow punctures and with short 
longitudinal carinae on anterior and antero-dorsal edge; metano- 
tum with a semicircular median excavation. Wings normal : vena- 
tion yellowish brown. Propodeum everyw here coarsely reticu- 
late, with the cells generally transverse, the largest of which 
begins at the slope to apex; the basal one is longitudinal and 
median. Abdomen dorsally smooth and polished, with fine punc- 
tures for hair; ventrally 1 and 2 have sparse large punctures; 
others with their apical portion (beyond transverse row of hairs) 
rather closely punctate ; last sternite mesad with some fine reticu- 
lations, its apical margin deeply cleft; ventral portion of anal 
spine well margined and with a few punctures except in the 
middle line. Insect set with rather sparse white hairs. Genitalia 
(Fig. 4): Outer lobe of stipes broad, basal third polished, middle 
lobe bilobed, inner lobe simple. 
Type @. 119 and numerous ¢ paratypes; Los Banos, 1916- 
1917. Some variation in size in both sexes, and the females may 
have more reddish brown than in type.

behind eyes, and subtriangular as viewed from above. Mandibles

raised mesially, frons without bituberculation near base of an- 
tennae, but with a median pit; eyes unusually large and proxi- 
mate; vertex rather pointed (rounded subconical), anterior ocel- 
lus rather distant from posterior ones ; antennae subclavate, basal 
articles long, 3 and 4 subequal; neck of pronotum with some fine
