1912] Brazilian Ichneumonide and Braconide 205 
line and the lower side originating at the same point so that the cell is 
thus three-sided. Submedian vein bordered by a hyaline streak as in 
H. fishert. 
One male collected by Mann and Baker; Manaos, Brazil. 
This species is very similar to H. fishert Viereck from 
eastern North America, and aside from the form of the antenne 
and wing venation differs only in its color characters. Mr. 
Mann’s discovery of the Brazilian form is very interesting as 
the first representative of the genus was discovered in 1907 by 
Schmiedeknecht in Europe. Shortly afterwards it was found 
to occur in North America. 
The four species so far described may be separated as

Subfamily MICROGASTRINE 
Mirax brasiliensis sp. nov. 
Female. Length 2.2 mm., ovipositor as long as the head-height. 
Head and thorax pale honey-yellow, abdomen somewhat lighter; legs 
whitish-yellow; antennze fuscous beyond the second joint; wings hyaline, 
with pale testaceous stigma and veins. Head transverse, twice as wide 
as thick, rounded on the temples behind the eyes; ocelli in an equilateral 
triangle, the space between them one third as great as that between the 
lateral ones and the eye margin. Front excavated on each side above 
the antennz, the depressions separated by an elevated triangular space 
that extends down to the level of the antenne. Face smooth; elevated 
medially, broadly so below and narrowly so above where the median 
line is almost carinate. Clypeus separated by a depressed line and with 
a large circular fovea on each side, its lower edge projecting but straight 
in front view. Mandibles black at tip, with two small teeth at apex. 
Antenne 14-jointed, as long as the body, tapering; scape short, but 
little longer then the pedicel which is slightly more than half as long as 
the first flagellar joint; joints beyond growing very gradually shorter, 
none less than two and one half times as long as thick. Eyes elongate- 
oval, much narrower below; malar space very short, with furrow. 
Mesonotum with crenulate furrows on its anterior half; sharply narrowed 
in front of the tegule. Scutellum long, with parallel sides behind, but 
widened in front, its base with a curved, deep, linear impression which is 
crossed on its bottom by numerous carine. Metanotum irregularly 
areolated; with a median carina that bifurcates behind, a straight 
transverse carina behind, and a curved carina on each side at the base
