1915] New Chalcidoid ITymenoptera Zito 
2. Pheidoloxenus wheeleri new genus and species of the Encyrtini. 
Female: Head quadrate, apparently lenticular, the antenne inserted 
near the mouth, 10-jointed with one very short ring-joint, the club 
solid; scape strongly compressed, widening strongly distad, the pedicel 
normal, the funicle compressed, its joints not annular but much wider 
than long, widening distad; club two-thirds the length of the funicle; 
pedicel slightly longer than wide at apex. Middle tooth of mandible 
obtuse, much the largest, the other two subequal and small. Maxillary 
palpi 4—, the labial 3— jointed. Wings mere scales. Legs simple, the 
middle tibial spur stout, the hind tibial spur single. Propodeum non- 
carinate. Abdomen with a short petiole, stout, oval, the ovipositor 
inserted at about distal fourth. Pronotum large, wider than long, 
distinctly longer than the scutum or scutellum, the axille separated a 
short distance. 
Length, 1.85 mm. 
Yellow brown, the club black; the body washed with metallic 
purple except the scape, funicle, pedicel and four proximal joints of the 
tarsi. Fore wings purple. Body scaly and with numerous minute pin 
punctures. Funicle 1 less than a third of the width of 6 but nearly as 
long, less than half the length of the pedicel. Fore wings nearly twice 
longer than wide at apex. Distal joint of maxillary palpus nearly as 
long as the other three combined. 
From one female on a slide in the U. S. N. M., ‘‘ From nest 
of Pheidole. Pheidoloxenus wheelert Ashm.’’ 
Type: Catalogue No. 19336, U. S. N. M., the foregoing 
female on a slide. 
This genus was partly described by Ashmead as an Asaphine 
Pteromalid. According to J. C. Crawford, Wheeler has already 
figured the species. 
3. Eunotus americanus new species. 
Female: Length, very variable, average about 1.20 mm. 
Black, the head very dark green, the abdomen shining. Wings sub- 
hyaline, the venation pale yellow, the legs and antennz reddish yellow, 
the coxee subconcolorous, also the pedicel. Head densely finely scaly, 
nearly scaly punctate, the thorax a little more densely so. Scutellum a 
half longer than the scutum. Propodeum short, areolate or foveolate, 
the areas not large. Abdomen nonsegmented, glabrous. Postmarginal 
and stigmal veins subequal. Hind tibial spurs double, much unequal. 
Antenne as in the figure of acutus Kurjumov but the second articulation 
of the club is absent, the club thus but 2-jointed; insertion on the 
clypeus or nearly. Lateral ocelli not touching the eye margin. 
The male is the same but the antennal club is 3-jointed, the 
flagellum filiform and about as figured for acutus. Male mandibles 
bidentate, both teeth acute and equal.
