the summit of crest gently sinuous, and backward sloping 
to the acute angulate produced apex, the margin here 
being distinctly sinuous or trisinuate toward the apex ; 
viewed from above the crassate-sinuate margin becomes 
thin toward the apex, the acute posterior process being 
produced beyond the hind femoral apices; lateral lobes 
Insinuate, the posterior angles subreflexed and truncate ; 
elytra rather large, elongate; wings fully explicate, 
strongly extended beyond the pronotal apex; anterior 
and middle femora elongate, margins entire ; hind femoral 
margins above arcuate, granulate, below substraight, and 
sparingly hirsute, hind tibiae rather stout, armed with 
spines; the first articles of posterior tarsi longer than the 
third, the second and third pulvilli equal in length, the 
first minute. 
Female.—Entire length of body to end of wings 
19*5 mm.; pronotum 17 mm. ; height of dorsum from

Stegaceps, gen. nov. 
Face little oblique ; body granulate ; eyes conoidal in 
profile. Vertex wide, median carina produced; antenna 
very short, inserted below the eyes, the distance between 
them much greater than the space intervening between 
them and the eyes ; frontal scutellum above divided be¬ 
tween the paired ocelli and distinctly widened between the 
antennae. Pronotum anteriorly acute-angulate produced, 
slightly extended beyond the head, posteriorly lengthily 
extended beyond the hind femoral knees, dorsal disc trans¬ 
versely tectiform, acute compresso-cristate, in profile arcu¬ 
ate ; lateral lobes posteriorly bisinuate; body bearing elytra 
and wings ; anterior and middle femora elongate, margins 
minutely subcrenulate; hind femoral magins above 
minutely crenulate, below entire, antegenicular spine 
acute, genicular spine moderately expressed; first articles 
of posterior tarsi slightly longer than the third. The type 
is S. brevicornisj herewith described.
