SCUTELLEROIDEA OF IOWA AT, 
rare in 1897, three specimens having been taken at Ames. It is 
most likely to be taken in prairie pastures.

Body elongate oval, pale yellowish to testaceous, variegated with fuscous 
or black. Head long, bronzed, distinctly narrowing toward tip; marginal 
and submarginal lines yellow, the surface densely, rather finely punctured 
and with remote whitish pubescence; tylus yellowish at tip and slightly 
longer than lateral lobes. Rostrum reaching to middle of second visible 
ventral segment, dull yellowish, the apex piceous. Antennae fuscous, the 
incisures paler; basal segment pale clay yellow. Pronotum regularly con- 
vex, the lateral margins straight, edges smooth, compressed; surface re- 
motely punctate with fuscous and pale brown, the fuscous punctures 
forming two oblique longitudinal rows either side of the median line; 
sometimes another and fainter ray extends forward from the humerus; 
eallosities surrounded by a group of fine black punctures; posterior 
angles moderately rounded, the anterior angles iess noticeably rounded. 
Secutellum elongate, narrowing gradually to tip, punctured rather finely 
but irregularly with pale brown to black. A series of blackish punctures 
at base either side of the middle curves outward to beyond the middle; 
median line pale clay yellow, expanded for almost the posterior one-half 
where the margins are sharply defined by black punctures. Venter pale 
clay yellow, the punctures smaller, paler and more remote than in d. 
aeneifrons; edge of abdomen beneath with obsolete or entirely without 
black spots; connexivum above black within, the outer margin immacu- 
late, pale clay yellow. Sixth visible ventral segment with anterior pro- 
longation narrow, somewhat rounded. Legs pale yeilow. The number of 
fuscous dots on the femora averages less than in H. aeneifrons; last tar- 
sal segment and claws piceous. Length, 6.0-8.0 mm. Width across pro- 
notum, 4.0-5.0 mm. 
In this species the difference in size, as well as, in some cases, 
the color between the two sexes is very marked. The male is 
much smaller than the female, with a more pointed seutellum 
which is reticulated above to a greater or lesser degree with 
black. The smooth median line with its expanded apex is less 
plainly indicated while the yellow submarginai line is slender, 
more obscure, sometimes obsolete before the base. Even the 
females are subject to a good deal of variation in size, general 
coloration, density of punctuation and the distinctness of the 
yellow submarginal line of the head.
