slightly broader than the anterior portion of it; vertex with the lateral 
borders well elevated and with a distinct and moderately prominent 
median carina; frontal costa narrow, scarcely more than, one-half as 
wide as the interocular space in either sex, percurrent, sulcate at the 
ocellus and, like the entire face, punctate; eyes prominent, not as long 
as the infraocular portion of the genae, in the female less than two-thirds 
as long; antennae uniformly dark reddish brown. Pronotum moderately 
slender, the posterior process rectangular or acute, there being considerable 
variation in this respect; median carina moderately elevated on the 
prozona, linear on the metazona; prozona about two-thirds as long as 
the metazona. Elytra with a nearly solid black band at the humeral 
angle, a more or less broken one across the middle, and across the center 
of the apical half a third band which is usually broken up and lost in the 
black neckings that occupy the apical fourth of the elytra ; the basal portion 
of the elytra, before the humeral band, is darker in ground color than the 
rest of the ground surface; wings moderately broad, not quite twice as long 
as the greatest breadth; disk pale yellowish, the fuscous band represented 
by a cloud on the anal field and usually a slight infuscated spot near the costal 
margin; sometimes the band is not represented at all and there Ts never 
a costal tasnia. Posterior femora ashy on the outer face with a black 
band across the apical third and a large infuscated spot on the upper half 
just before the middle; inner face black with two broad white bands, 
the lower sulcus white with a subapical black band and sometimes slightly 
infuscated on the basal half; hind tibiae yellowish, the spines black on 
the apical half. 
Length, male, 18 mm., female, 25 mm.; antennae, male, 9.5 mm.; 
hind femora, male, 10 mm., female, 13 mm.; elytra, male, 18 mm., female,

Eight males,' 3 females, Spreckels, Monterey Co., California, 
on sugar beets, September 20, 1904 (E- S. G. Titus). 
Superficially this species bears a very close resemblance to 
Trimerotropis albescens McNeill, but is very distinct from it. 
Albescens has the antennae barred with black and white while 
here it is unicolorous, the pronotum of titusi is more slender 
than that of albescens and the color is considerably darker. 
Finally the hind tibiae of albescens are blue while in titusi they 
are yellowish.
