Elytra broad as in variegata and pallida. Eostrum reaching to apex of 

 penultimate ventral segment. Hind edge of genital segment feebly 

 arcuated in the female, quite deeply notched in the male, leaving a con- 

 spicuous lobe or tooth at the lower angle next the ventral insicure; dorsal 

 plate of the male long and triangular at apex. In the male of septen- 

 trionalis the genital segment is truncated, without a ventral notch, and 

 the dorsal plate is short and truncated, not exceeding the plates. 



Color fulvo-testaceous, becoming more gray on vertex and pronotum; 

 elytra milky-white with pale nervures, varied with testaceous-brown and 

 dotted with fuscous, the brown forming a longitudinal series of three 

 squarish patches on each elytron, the anterior two sometimes obscurely 

 united by a brownish cloud along the claval suture; inner apical cells 

 mostly brown crossed by white nervures and veinlets; the fuscous dots 

 arranged along nervures and on costal margin, where they form two 

 irregular marks before the apical areoles. Wings infuscated at apex. 

 Pronotum irrorate with brown, the fulvous mesonotum more obscurely so. 

 Beneath and legs almost uniformly fulvo-testaceous with a dark lateral 

 vitta covering the eye and shading below to black with the extreme edge 

 of the inferior aspect of the pronotum clear white. Front whitish, with 

 the base to a little below the upper angle of the eye darker and irrorate 

 with brown. Edges of the pleural pieces and ventral segments whitish. 



Described from numerous examples taken on the Jeffrey pine, 

 especially along the southern slope of Mount Tallac, after July 

 19. They were also beaten from cypress bushes growing on this 

 same slope and here the young were taken with the adults. This 

 is of a clearer gray than any of our other species of Elidiptera. 

 It has much the aspect of the eastern variegata but that is a larger 

 and darker form with a shorter vertex. In my key of 1907 it runs 

 directly to septentrionalis but may be distinguished from that 

 form by its more whitish aspect, broader form, the mostly pale 

 front and the different genital characters. 



Catonia nemoralis, new species 



Size and aspect of grisea, to which it is closely related; ashy gray 

 with the elytra irrorated and mottled with fuscous and dotted with white 

 veinlets, the front uniformly whitish-testaceous. Length 5 mm. 



Vertex short, truncate, broader than in grisea, not as long as width 

 of each compartment. Pronotum at the middle scarcely as long as vertex. 

 Mesonotum shorter than in grisea, about twice length ot vertex and pro- 

 notum together (in grisea three times as long). Front broader than in 

 grisea, but little wider toward clypeus. Last ventral segment of the 

 male truncated, with a subacute triangular median tooth about one-third 

 the length of the valves, while in grisea it is nearly half their length. 

 Plates oblong, a little narrowed at apex.
