NORTH AMERICAN LEPIDOPTERA. 109 



Coloi-s olive aud red brown ; hodj- more graceful and slender. 



Discal cell of primaries free ; vitreous field of secondaries usually crossed by 

 five nervules. 

 Thorax beneath with lateral red shades; hiud wings beneath with a pale 



shade at anal angle gracilis. 



Discal cell of primaries crossed by a bar of scales; vitreous field of secondaries 

 crossed by six nervules. 



Inner margin of band of primaries inwardly dentate tliysbe. 



Inner margin of band of lU'imaries not dentate. 



Larger var. riiflcaiidis. 



Smaller var. bufl'alooiisiiii. 



The synonymy will be given in the list at the end of thi.s ])tij)er. 



LEPI^ESIA Grt. 



Pr. Ent. Soc. Phil, v, 38, 1865. 



Head small, eyes small, more or less distinctly lashed ; tongue 

 moderate or long, corneous ; palpi somewhat variable, usually short, 

 rarely forming a short snout {gaune) ; body stout, sometimes more 

 or less depressed ; abdomen with inconspicuous lateral tufts, often 

 wanting, and a more distinct anal tuft ; posterior margins of seg- 

 ments spinulose. Feet moderate, anterior tibi?e stout, with a series 

 of stout spines or claws outwardly and at tip. Primaries rather 

 elongate, outer margin oblique, sinuate, hind angle distinct and 

 somewhat produced. Secondaries somewhat variable in form, usually 

 somewhat produced. The venation presents nothing peculiar. 

 There is never any difficulty in recognizing this genus as the com- 

 bination of clavate antenna3 and armed fore tibiie is found nowhere 

 else. 



Taken as a whole the genus is not a compact one. In Mr. Grote's 

 List the species here united are divided among Lepi-sesia, Euproser- 

 pinu'< and Pogocolon, and at first sight the division seems justified. 

 As, however, we get the species together and compare them more 

 closelv, it will be seen that the differences are hardly tangible, and 

 that following the same line, clarkliT^ is not congeneric with gaurce, 

 and, indeed, offers better characters for separation, while terlooi Hy. 

 Edwards, certainly does not belong with its associates and probably 

 furnishes an ally to Arctonotus. The species is Mexican, and I am 

 at a loss to know why it stands in our catalogues, as it has never 

 been recorded from this country. 



■•■■■ I find that Mr. Butler has made this the type of Dieneces.
