PERIGRAPHA Lederer. 



Eyes hairy. The front without a projecting knob. The antennae 

 pectinate in both sexes, but the pectinations in the female are shorter. 

 The collar is cut out. The thorax bears behind the collar a sharp- 

 edged, longitudinal crest, and also has an angular projection on each 

 side. There is no metathoracic tuft. The abdomen is smooth, ex- 

 cept that the first segment is provided with a short, thick, hairy tuft. 

 In the female there is a projecting ovipositor. The tibiae are un- 

 armed. The apices of the anterior wings are rectangular. All the 

 marking clear and distinct.

I have already shown in» the Canadian Entomologist that P. Nor- 

 mani Grote, was erroneously referred to Perigrapha. The present 

 species agrees precisely with Lederer's definition of the genus except 

 in the extruded female ovipositor; but this alone is hardly sufficient 

 to render necessary a generic separation. The ordinary spots and 

 lines in this species are remarkably conspicuous ; for a detailed de- 

 scription of it see the original paper. 



Tsenioeampa modifica nov. sp. 



Expanse 35 mm. Length of body 17 mm. 



The eyes are hairy. The female antennae simple, with a clothing 

 of fine scattered hair. The male antennae more evidently setiform. 

 The palpi, front, collar and thorax, clothed with a dense, erect, 

 villosity. The abdomen and thorax untufted. The female oviposi- 

 tor extruded. The anterior wings are gray, overspread with blackish 

 atoms. The costa is distinctly edged with carneous, as in Panopoda. 

 The interior and exterior lines are alone distinct; they are blackish, 

 accompanied by pale, even, conspicuous shades. The former is 

 oblique, the latter is rounded, parallel with the exterior margin, 

 and nearer to it than usual, thus narrowing the terminal and sub- 

 terminal spaces. The ordinary spots are distinct, filled with black 

 and surrounded by pale annuli; the orbicular small and round; 

 the reniform of usual size, narrow and upright. The subterminal 

 line is light, faint, containing a series of interrupted blackish dots. 

 The fringe concolorous, with a yellow line at its base. The posterior 

 wings uniform dark fuscous, with a discal dot. The base of the 

 fringe is yellow ; it is separated from the outer whitish portion by a 

 dark central line. Beneath, the anterior wings are dark gray, tinged
