Exi)aiise of wings, 25 to 30iuiu = l to l.-IO inches. 



IlAiiiTAT. — New York to Texas; District of Columbia in rluly and 

 August. 



Tliis species is by no means so common as the preceding, and is not 

 generally distinguished from it. It is sometimes ranged as a pale form 

 of E. lubricaUs^ or more frequently a pale form of that species is labeled 

 E. (lenticulalis. The present si)ecies is always recognizable by the 

 ol)vious median shade line and the dusky i)atch in the outer inferior 

 angle of the median s])ace. The rather prominent pale rings to the 

 margin of the abdominal segments are also sonjewhat distinctive. From 

 the specimens I have seen the species varies much less in size and in 

 grouiKl color than E. Ixhricali-s, and is a very well-detined one. 



Unfortunately, I failed to find among the material before me any 

 female specimens, hence can not s})eak of the antennal characters of 

 that sex. The male antenna' resemble quite strongly those of E. lubrl- 

 calis; but all the features are more intensilied: the joints are broader, 

 the scales more dense, the lateral bristles are longer and more stout, 

 the tuberculate processes bearing hair, are more prominent and the 

 hairy tufts are more conspicuous, and, linally, the tubercles giving rise 

 to separate hairs are much more numerous. Examined with a hand 

 lens, the imi)ression is that the member is much more bushy than m the 

 preceding species. In the primary sexual characters there is little dif- 

 fering from the preceding. The type of the harpe is exactly the same, 

 and only the proportion of the parts differ slightly. In wing form this 

 species is quite considerably different from E. luhricalis, the i)iimaries 

 being distinctly more frigonate, proportionately shorter and luoader, 

 making the outline (juite markedly different.

Head, thorax, and primaries blackish, smoky, glistening; second- 

 aries and abdomen jtaler, more thinly scaled. Primaries almost immac- 

 ulate, only the most vague traces of the ordinary lines being observable 

 in most si)ecimens. Sometimes, however, all of them are tiaceable or 

 at least feebly indicated by pale scales, though more often they are not 

 traceable in any way, and we have a uniform smoky brown surface 

 delightfully easy to describe. The secondaries are also as a rule nearly 

 immaculate, though some traces of the usual median and extra median 

 dusky brands may be discovered, and in some cases these are fairly 

 well marked. l>eneath, the wings vary from quite pale whitish gray 

 to smoky, and the usual transverse lines are sometimes well marked, 

 especially on the secondaries. The maculation is most evidi'ut when 

 the ground is lightest and then also a discal spot is usually present.
