sects, which is at times at variance with their structure, so that both 

 and together must be studied, to determine properly their classificatory 

 position. The failure, at times, to do this, seems to me the only fault

 proportions of Fsi/chonoctua would lead us to consider it as belonging 

 to the Xoctuiilse. 



Sub-Family, LITHOSIIN.E. 



CYTOEUS, nov. gen. 

 Allied to Crocotn. Hiibner. Head large and prominent. "Front" 

 broad. Antennae short and stout, tapering to the tips, biserrate. 

 Wings broad. Anterior wings rounded at the apices and along exter- 

 nal margin. Posterior wings ample, rounded at costal angle and along- 

 external margin. Abdomen short, not as long as the secondaries. Tho- 

 racic parts well developed; prothoracic pieces broad. Labial palpi flex- 

 uous ; terminal joints somewhat depressed, exceeding the front. This 

 genus differs from Crorota in the wider clypeus, more prominent eyes, 

 shorter, stouter and serrated antenuce, and in the rounded apices of the 

 piimaries. 



Cytorus latus, n. sp. (Plate 4, fig. 1, % .) 



Primaries ferruginous-tawny, with irregular shades. A prominent 

 broad white basal streak extends for one-fourth the leng-th of the winu' 

 longitudinally below the median nervure. Secondaries pale reddish- 

 luteous, contrasted, in their much paler color, with the dark primaries; 

 entirely immaculate. 



Under surface of both pair, immaculate. The primaries are covered 

 with brighter, more reddish scales than their upper surface; seconda- 

 ries paler, concolorous with their upper surface. Head, caputal append- 

 ages and thorax, immaculate, nearly concolorous with primaries above. 

 Abdomen somewhat paler than thorax, without markings. Two speci- 

 mens. Exp. S , 1.00 inch. Length of body .40 inch.

CROCOTA, Hiibner. 

 Crocota heros, n. s. (Plate 4, fig. 2, 9 •) 



Size large. Palpi moderately exceeding the "front;" antennae slen- 

 der and rather long. Tawny fulvous. Anterior wings straight along 

 internal margin ; costal margin arcuated, depressed at apex ; external 

 margin very moderately oblique, nearly straight. Squammation ob- 

 scure tawny fulvous, presenting dark leflections from the discal spot
