' 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 saratogeiisis, 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 pygofers 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 wittPsaratogensis 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 coxa?: 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
