One male from the Rio Madeira (Madeira-Mamoré R. R. 
Camp 39), Brazil, Mann and Baker. 
These are the first two South American representatives of 
the genus to be discovered, although three have been described 
from North America by Ashmead. Only one of these, dyari, is 
known in the female sex. 
Cryptanura uniformis sp. nov. 
Male. Length 12 mm. Head, thorax, and antenne black, with 
white ornamentation; legs and abdomen, except part of petiole, bright 
ferruginous. The white markings are as follows; annulus of 6-7 seg- 
ments on antennze; clypeus except lower and side margin, face, wide 
anterior orbits, broad stripe behind eye, and palpi; prothorax with an 
elongate spot on each side above and below; mesonotum with a round 
spot on the middle lobe behind the tegule; elongate spot at side of 
scutellar fovea, scutellum and post-scutellum with side lines from each; 
metanotum with four broad longitudinal stripes on posterior half and a 
large spot at anterior angles; mesopleura with spot beneath wing and an 
elongate spot below; mesosternum with an elongate spot on each side. 
The legs also bear white on the anterior coxze which are white in front 
and black behind, while the ferruginous middle coxe are whitish in 
front. The ferruginous color is very uniform except that the anterior 
four legs and hind tarsi are more nearly fulvous. The apical joints of 
tarsi and the enlarged part of the abdominal petiole are piceous. The 
head is rather finely punctate on the face and clypeus, and the front 
bears two small spines above the antenne; ocelli rather large, the 
posterior pair closer to one another than to the eye margin; eyes showing 
a very slight pubescence. Mesonotum deeply and sparsely punctate 
medially, nearly smooth on the sides, scutellum at the base with a very 
deep quadrate depression that is longitudinally striated. Metathorax 
with a complete transverse carina, joining a complete pleural one, 
and with a basal median and lateral area partly enclosed. Metathorax 
rugose-reticulate over its entire surface, more coarsely so behind, its 
spines long, slender, erect. Pro- and mesopleuree smooth and shining, 
except for longitudinal striations below on the propleura and mesopleura. 
Mesopleura with a round impression medially behind, and rugose near 
the base of the coxa. Hind coxe punctate near base. Petiole of abdo- 
men very highly polished with a deep groove along the side passing 
below the spiracle which is situated just before the apical third of the 
petiole; following abdominal segments smooth, impunctate. Wings 
hyaline, infuscated at extreme tip; veins black, areolet very incom- 
pletely closed, the outer vein nearly hyaline. Submedian cell slightly 
shorter than the median; discoidal nervure inserted at the middle of the 
second discoidal cell; transverse median vein of hind wing broken at 
its lower fourth. 
Described from a male taken by Mr. Wm. M. Mann, at 
Ceara-Mirim, Rio Grande do Norte, Brazil.
