of the two 5 specimens before me. I have both sexes of undularis, not 

 differing perceptibly j but of umbrij^etmis I find I have only females. 



Zanclognatha l^vigata, Grote. 



A large series shows immense variation in color. The most extreme 

 9 variety has the median space ochreous, the basal and terminal fields 

 blackish ; this form is very striking. The species may be known by th& 

 irregular subterminal line. The reniform is sometimes open ; again 

 solid and black ; the orbicular is sometimes visible near the t. a. line. 

 Sometimes the median space is bronzed and dark ; again the whole wing 

 is coucolorous purply-brown ; the median shade is sometimes present 

 and again obsolete. The species is common at light and at sugar near 

 Buffalo, N. Y., in June and July. 



Zanclognatha miwimalis, n. gp. 



$ 2 . — Half the size of cruralis or laevigata. Of the same dusty ochrey 

 color, varying in depth (one 2 very dark). Fore tibiae of the male with 

 the usual brush of pale and dark hair. Smoothly scaled; subterminal line 

 straight, inconspicuous, more or less margined with pale externally, run- 

 ning from costa to internal margin. T. p. line much as in cruralis, a 

 little drawn in submedially, irregular, accented on costa, Discal spot 

 solid ; t. a. line thrice waved. Hind wings paler, powdered with fuscous. 

 A mesial line bent and most distinct at anal angle. On both wings, a 

 terminal interrupted line. Beneath paler, with discal dots and distinct 

 mesial line more or less plainly crenulated ; subterminal line absent or 

 indistinct. Expansion, 21 to 25 millimetres. Maine (Mr. Charles Fish)] 

 New York. 



This species is the smallest known to me. I have examined four 

 specimens. 



Deecetis, n. g. 



The fore wings are deeply excavate to vein 4, so that there is a re- 

 semblance to Aventia. The palpi are disproportionally long stretched 

 straight out, the short, third joint vertical; the elongate second joint as 

 in Eypena. Ocelli; eyes naked, unlashed. Legs unarmed, untufted. 

 Male antennae very shortly pectinate, setose. Fore wings deeply' exca- 

 vate to vein 4; external margin produced at the middle about veins 4 

 and 3, thence sloping inwardly to internal angle; 12- veined, vein 1 

 simple, 2 from submedian at basal f, 3 shortly before 4, 5 on a line 

 with 4 from a cross- vein very near 4 at base, cell open, 6 opposite 5 

 from a cross- vein, 7 and then 8 out of 9, 10 within 6 from the upper 

 side of the vein about midway between 11 and 7. Hind wings rounded, 

 a slight depression opposite the cell; 8-veined, two internal veins counted 

 as 1, 3 and 4 from one point, 5 from a short cross- vein within 3 and 4, 

 cell open. The moth is light purplish-gray ; beneath, the abdomen and 

 wings are stained with ochrey and brown. It looks like one of the 

 Pyralidce, but from its structure I refer it to the Deltoids.
