A single specimen in the Osborn collection is from Bed- 

 ford County, Pa., Aug. 12. 



Very closely allied to impunctata, and is Fitch's variety 

 a of this species and Van Duzee's female impunctata of his 

 1907 paper. In 1910, Van Duzee recognized this as being 

 a distinct species, having both sexes with the frons entirely 

 black. In the writer's opinion, this is probably a color 

 variety of impunctata. 



Structurally identical with impunctata to which it is most closely 

 allied, with the exception of the male genitalia which are slightly dif- 

 ferent. Easily distinguished by having the front entirely black, cly- 

 peus white, and the vertex and pronotum without the black discal 

 spots. The legs are whitish with a dusky spot on the base of the 

 hind tibiae exteriorly; in impunctata the legs are immaculate whitish. 



Female genitalia substantially as in impunctata. In the male the 

 median tooth of the basal valve is short triangular, its blunt apex 

 attaining the middle of the plates, the margins either side of the tooth 

 forming a moderate sinus and then retreating to the basal angles. In 

 impunctata this median tooth is long and acute, attaining the apex 

 of the plates, and the margins either side are deflected at right angles, 

 making the basal portion of this valve of nearly equal length across 

 its whole width. 



Length same as in impunctata 6 mm. 



Catonia grisea VAN DUZEE 

 (1908 Proc. Acad. Nat. Sci. Phila., lix, p. 482). 



Known from Ontario and New York. 



Larger than most of the eastern species. The elytra 

 are gray varied with white, and the scutellum brown with 

 two black ocellated points posteriorly, which differentiate 

 it from the other species. 



Vertex pale, almost square, feebly angled anteriorly, produced 

 about half its length before the eyes, the lateral foveae marked with 

 a dark point. Frons elongate, quite strongly narrowed basally with 

 the sides almost straight and the carinae strong; pale yellowish, ob- 

 scurely irrorated on the base of the frons and clypeus, leaving a 

 paler intermediate band, indicated on the marginal carinae by two 

 brownish spots. Pronotum shorter than the vertex, rather sharply 

 angled and marked with a blackish line beneath the eye, tricarinate. 

 Scutellum very long, tricarinate, pale quite strongly maculated with 

 brown in the female, carinae pale, and a black spot placed in a pale 

 round area within the lateral carinae near the apex. Elytra whitish 

 tinged with smoky especially toward their tips; nervures white, the 

 areoles with numerous imperfect, transverse, white veinlets; on the 

 costa are a few larger brown spots. Beneath pale, the abdomen
