Frons and mesoscutum punctate, the latter more weakly so; occipital

(8) pallipes (Curtis). 
(1) EUPHORUS OCCIPITALIS, new species 
Most similar to maculipennis, from which it differs, however, in 
having the occipital carina complete, in the presence of a distinct recur- 
rent vein, and in having the first cubital and first discoidal cells com- 
pletely closed. 
Female.—Length 2mm. Head from above subquadrate, in profile subtriangu- 
lar, the anterior angle being the point of insertion of the antennae; eyes large, 
prominent, converging anteriorly; face short and receding, smooth, not densely 
hairy; malar space a little shorter than basal width of mandible; cheeks a little 
narrower than eyes, broader than temples; vertex broad, convex; frons long, 
gradually declivous, smooth and polished; ocellocular line slightly longer than 
postocellar line, more than twice diameter of an ocellus; antennae 15-segmented, 
a little shorter than head and thorax combined, slightly thickened toward apex; 
scape about twice as long as thick; pedicel as long as thick; first flagellar segment 
about as long as scape, slender, the following gradually shorter and thicker, except 
apical segment, which is much longer than that just preceding. 
Thorax slender, much narrower than head; mesonotum smooth and polished; 
notaulilacking; impression at base of scutellum broad and deep, divided by longi- 
tudinal carinae into four foveae; propodeum elongate, weakly declivous, rugulose 
reticulate; mesopleurum mostly smooth and shining; metapleurum finely rugulose 
and opaque; stigma broad, less than twice as long as broad; radial cell very short, 
less than one-fourth as long as stigma; first abscissa of radius punctiform or 
lacking; first cubital cell slightly longer than first discoidal, both completely 
closed; recurrent vein entering first cubital cell, removed by nearly its length 
from intercubitus; median and submedian cells glabrous; submediellan cell 
complete; nervellus distinct. ; : : 
Abdomen at third tergite as broad as thorax; first tergite broadening slightly 
behind, nearly three times as long as broad at apex, finely longitudinally rugulose 
striate, the spiracles only very slightly beyond middle; remainder of abdomen 
polished; ovipositor subexserted.
