Acrouyctiui: with several-haired warts and often with secondary 

 hair; with fine setiform granulations, with which there may be mixed 

 larger conical ones. Epicrania high, extending over 1 l-;5 times the 

 height of the front above its top; adfrontals very wide, the upper 

 setae far apart and high above the top of the front ; clypeal setae closer 

 together than the frontal seta and puncture; i and ia of labrum sep- 

 arated by a distance less than the width of a setigerous puncture; 

 last joint of maxillary pulpus short. 



With secondary hair; labrum more deeply notched. Hi and it; of labrum 

 well separated, head dark, front about as wide as high, setae i and it of 

 labrum form an angle of about fiO degrees with the horizontal. Adfrontals 

 not especiallv wide at the top of the front. 



Examples A. (Hyboma) hasta. Fig. 10.3. 



A. (Triaena) hastulifera. Fig. 102. 



Similar; adfrontals with an enlargement at the top of the front, 

 which contains the setae and i)iincture; labral notch not so deep. 

 Example A. (Triaena) occidentalis (interrupta). 

 Figs. 1, 12 and 26. 



Similar; head i)ale, labral notch shallower; front narrow; adfrontals 

 unusually high and yet narrow; clypeal setae closer together; setae t 

 and ii in a line onlv 'M degrees from the horizontal; ia distant from t. 

 F^xample A. (Acronycta) leporina. Fig. 105. 

 No secondary hair, labrum decijly notched; head black; front narrow; 

 Hi and iv of labrum ol)liquely placed, separated by only half the vertical 

 distance that separates i and ii horizontally. 



Example A. (Eulonche) oblinita. Fig. 104. 



No secondary hair; lalirum nntchcd (Hily 1-4 its height; front wide. 

 Example Simyra (Arsilonche) henrici. F'ig. lOtl. 



Jn the remaining forms there is no tufted or secondary hair ; there are 

 no fine setiform granulations, though there may be coarse ones; the 

 front is larger in proportion to the epicrania and to the adfrontals; the 

 adfrontal setae are closer to the front and to each other; i and ia of 

 labrum are more widely separated. 



Cuculliini Clypeal setae closer together than the distance between 



frontal seta and puncture, epicrania not reduced, labral setae about 



evenly spaced. 



Adfrontals i le\'cl w ilh lop of front ; clyjieal setae much closer together 

 than frontal seta and puncture; labral setae i and ii quite evenly spaced; 

 front as wide as high ; adfrontals narrower; set;c of labial ]>alpi long. 

 Iv.xample Cucullia sp. (undescribed). Fig. 110. 



Adfrontal setae t higher, clyj)eal setae farther apart; laV)ral setae dis- 

 tinctly arranged in jiairs; front narrow, adfrontals wider; setae of labial 

 palpi minute. 



F^xamj)k' Scopelosoma sp. 

 Adfrontals i high, c Ivpcal setae much closer together than frontal seta 

 and puncture; labral setae i and j'l distinctly arranged in ])airs; fr<mt dis- 

 tinctly higher than wide; setae of pal]> intermediate. 

 Example Calocampa curvimacula. 



Earia.s chlormia (of Europe) is made the type of a subfamily or 

 jilaced with Xycteola. Claw very deeply notched; second joint of 

 antenna short, tubercles ii of 8th abdominal segment enlarged, and 

 also it) of thorax : ii of epicrania directly below i and close to edge of 

 adfrontals (as in some Micros) front a nearly equilateral triangle, 

 adfrontals quite broad, and rather ill-defined; upper ocellus l)ehind 

 second instead of being above it. Fig. 112.
