APHROPHORA SIGNORETII Fitch. 
A. signoretii Fitch. Third Report Ins. N. Y., p. 70, 1856. 
Tawny-brown, varying to pale ochraceous, line on vertex 
and pronotum and marking of elytra almost obsolete; slightly 
smaller than samtogensis, with a shorter, blunter vertex and 
stronger front; length 8.5-lOmm., width 3.5mm. 
Vertex, sloping or depressed, very obtusely angulate, anterior and 
posterior margins parallel, anterior margin sharp to the tylus, tylus dis- 
tinct, slightly elevated; front moderately inflated, about equaling the long 
diameter of the eye, not produced anteriorly, forming an acute angle with 
the vertex; pronotum rather strongly depressed before the middle, but 
only slightly elevated behind, leaving it rather flat, side margins distinctly 
shorter than the distance between the ocelli; elytra moderately long, the 
costal margin reflexed anteriorly. 
Color: Vertex, tawny, darkest on the tylus, carina obscurely marked; 
pronotum tawny-brown, scarcely a trace of gray on the elevated disc, 
anterior depressed portion lighter, scutellum lighter on the disc; elytra 
varying from tawny to ochraceous, light bands, not very prominent, the 
anterior one arising well back of the scutellum and not attaining the costa, 
the posterior one arising near the apex of clavus and running nearly trans- 
versely to the costa. 
Genitalia: Female py gofers convex, moderately long, exceeded by the 
ovipositor, which does not reach the tips of the elytra; ultimate ventral 
segment of the male abdomen nearly twice longer than penultimate, one- 
half longer than its basal width, narrowing apically, disc convex; plates 
stout, forcep-like, black-tipped, their outer margins rounding, the inner 
ones obliquely divergent. 
Habitat: Specimens are at hand from New York and 
Ontario, Canada. 
This species has been confused with saratogensis to such an 
extent that it is impossible to separate the references ; it may 
be readily distinguished, however, by the forcep-like male 
plates, while in saratogensis they are nearly quadrate discs. 
GENUS LEPYRONIA A. & S. 
Vertex, together with the eyes, as wide as the pronotum, angularly 
rounding anteriorly, the margin sharp, disc nearly flat, without carina, 
tylus large, parallel margined; ocelli about midway between tylus and 
pronotum, nearly as far from each other as from eyes; front broad, moder- 
ately inflated, coarsely ribbed, except along a median band; rostrum, two- 
jointed, reaching the middle coxae; pronotum about three times as wide as 
its length on middle, anterior margin slightly rounding, lateral margins 
nearly parallel, sharply carinate, shorter than the long diameter of the 
eye, posterior margin deeply, roundingly emarginate, disc but slightly 
convex; elytra coriaceous, broad and rather short, outer margin broadly 
and regularly rounding to the acutely angulate apex; venation of the
