REPORT OF ENTOMOLOGIST.

ing the hind edge of the pronotum. Pronotum somewhat strangulate in 
advance of the principal sulcus, the lateral carinae not much interrupted 
though bowed, fairly prominent; the median carina straight, of medium 
height, cut a little in advance of its middle; hind edge of the disk some¬ 
what obtuse-angled. Tegmina and wings about equalling the abdomen in 
length, the apex of former broadly rounded. Hind femora normal, not 
quite reaching the tip of the abdomen. 
General color pale grayish testaceous, the sides of pronotum ob¬ 
scurely banded with dull black or brown, the disk of pronotum with the 
X-shaped pale marking of sordidus , costalis and parvus. Tegmina crossed 
with four heavy dark bands and marked basaliy with irregular small 
blotches. Hind femora decidedly trifasciate with fuscous externally; 
hind tibiae largely glaucous, the base pale. Sutures of abdomen nar¬ 
rowly black. 
Length of body, 19 mm., 9,28 mm.; of antennae, 7 mm., 9 ? 
8 mm.; of pronotum, A, 4 mm., 9,5 mm.; of tegmina, 17, 9,20; of 
hind femora, < 5 % 11 mm., 9 , 14 mm. 
Habitat. Fort Collins, Colorado, August 14, a single $ (C. P. 
Gillette); same locality, 1 and 1 9 (L. Bruner). 
TiHigroii'opSs inconspisua new species. 
A trifle under the medium size for the vinculata group to which it 
belongs, and at once recognized by its generally light color and compara¬ 
tively narrow, but well defined, posteriorly converging tegmina bars, 
together with the pale disk of pronotum. 
Head of moderate size, the eyes a trifle prominent and semiglobose. 
Vertex longer than wide and provided with a well-defined longitudinal 
carina. Antennae dark brown annulated with testaceous,nearly or quite 
as long as hind femora. Pronotum rather flat on disk but provided with 
a net-work of low, smooth ridges which gives its surface a granular ap¬ 
pearance; the anterior lobes very little tumid and furnished with a medi¬ 
an carina which is but little more prominent than that on the hind lobe; 
posterior edge of disk right-angled in both sexes. Tegmina extending 
nearly one-third (A) or only about one-fifth ( 9 ) of their length beyond 
the tip of abdomen, the veinlets on basal half or two-thirds very numer¬ 
ous and a trifle coarse, thereby giving to that portion of these members 
a sort of granular appearance.' Hind femora moderately slender, not 
quite reaching ( 9 ) or a little surpassing (A) the tip of abdomen. 
General color very light cinero-ferruginous, with the usual dark- 
brown or blackish markings of the group to which it belongs. In some 
specimens the anterior portion of pronotum both on sides and disk are 
marked with clusters of small black flecks, but in others this portion is 
entirely pale—being relieved only by the brownish dots which adorn the 
carinae of vertex, front, cheeks, pronotum, etc. The pale ferruginous 
tint which pervades the whole insect is due chiefly to the color of the 
bottom of punctuations which are well scattered over its surface. While 
the bands on tegmina are not solid they are quite prominent and made up 
of clusters of dark dots or by the infuscation of certain veinlets. O 11 
the basal portion these bands are narrower than usual and show a de¬ 
cided tendency towards converging posteriorly, while the apical portion 
is nearly destitute of markings save for the infuscation here and there 
of a few veinlets. Wings with their disks very pale greenish-yellow, 
crossed about the middle by a narrow fuliginous band which sends its 
anterior spur nearly one-half way to the base, the apical portion beyond 
the band perfectly transparent. Hind femora with lower sulcus yellow 
or at least with two pale bands. Hind tibiae, except 011 extreme base 
where they are dark-brown, pale greenish-yellow, a little infuscated be¬ 
yond the subbasal pale annulus and apically. F ront and middle legs 
with well marked dusky annulations. 
Length of body, A, 17 mm., 9, 24-26 mm.; of antennae, A, 40 mm., 
9, 10.5 mm.; of pronotum, A, 4 mm., 9, 5.5 mm.; of tegmina, 18.5 
mm., 9 ,24-25mm.; of hind femora, 10-10.5 mm., 9, 10.5-12 mm.
