much finer than above; clypeal process quite prominent, more so than in 
subulatus; mandibles black, rufous medially; cheeks with punctures ar- 
ranged in rows or striae; ocelli normal; flagellum of antennae uniform 
dark brown. Prothorax carinate, rounded on the sides and sparsely punc- 
tured, with two yellowish white dots laterally. Mesothorax and scutellum 
with a weak longitudinal median carina, almost imperceptible on the lat- 
ter, which has a reflexed margin and is very coarsely punctured; tubercles 
yellowish white; propleura with extremely fine punctures, mesopleura very 
coarsely punctured, especially anteriorly, and with several strong ridges or 
elevations running downward; crest before intermediate coxae distinct; 
metapleura with numerous longitudinal ridges; posterior face of meta- 
thorax with numerous polygonal reticulations; a strong median carina 
starts at the juncture of the abdomen and extends upward to about one- 
third of the altitude of the metathorax where it becomes bifurcate, the 
forks forming a balloon-shaped depression which is impunctate and almost 
smooth within; squamae terminating in quite long curved points; the post-- 
scutellum yellow, almost concolorous with squamae, and making it appear 
as if they were broadly joined medially. Postscutellar spine black, broad 
at base, and rapidly narrowed to an acute point. Abdomen with quite 
large, medium close punctures dorsally, exceedingly coarse sparse punc- 
tures ventrally; abdominal bands quite broad, those on one and two nar- 
rowly interrupted, remaining ones entire; apical segment with golden 
pubescence. Legs black, anterior and intermediate femora at tip beneath, 
and all tibiae outwardly more or less yellowish white, tarsi brownish; 
posterior and intermediate tibiae quite strongly spined outwardly. Wings 
clear hyaline excepting distal and posterior margins, which are smoky; 
netvures brownish. 4 
3. Unknown. 
Type, West Point, Nebraska, June 28, 1905 (P. R. Jones) ; 
paratype (?) Holt county, Nebraska. This species is related to 
subulatus Robertson by the acute postscutellar spine and the 
coarse puncturation of the abdomen. I am undecided as to 
whether or not the Holt county specimen belongs to this species. 
It differs in being rather smaller, has two white spots on the 
scutellum, the markings on the prothorax and tubercles are con- 
nected, and the sculpture not quite so strong. It may prove to 
be distinct.
