Notes on North American Lepidqptera. 103 



the ground color is black, but the entire costa is beautifully and broadly 

 banded with pink; on the posterior wings the ground color is also black, 

 but the white markings are larger than the above, the entire anterior half 

 of the wings are pink, excepting the central white band. 



Habitat. Colorado, June 18. 



This beautiful species will at once be recognized by its 

 vivid colors beneath. From the numerous species of Heli- 

 othis described by Mr. Grote from the same locality, it 

 differs at once by the unarmed tibise. 



Telesilla vesca, nov. sp. 



Expanse 23 mm . Length of body 10 mm . Eyes naked. The palpi and 

 front as in T. cinereola. Thorax untufted, concolorous. Abdomen smooth, 

 dark gray. The middle and posterior tibise are terminated by a pencil 

 like tuft in addition to the ordinary spurs. 



Different shades of brown prevail over the anterior wings, melting 

 gradually into one another; the basal space is chestnut-brown deepening 

 into black-brown on the first part of the median space, the outer and up- 

 per portions of the median space are cinereous-brown, beyond, the ter- 

 minal and subterminal spaces are dull gray-brown ; the ordinary lines are 

 cinereous and the spots are encircled by annuli of the same color; the 

 half-line and the interior line indistinct ; the exterior line distinct, even 

 and preceded by a darker shade line; it is followed by a series of black 

 spots on the nervules; subterminal line whitish, preceded by lighter brown 

 shades; orbicular and reniform spots distinct, concolorous, the former 

 rounded, the latter upright having the lower inner corner drawn in on the 

 median nervure. 



The posterior wings are blackish gray. Beneath uniform dark gray ; 

 both wings flecked with white atoms ; the posteriors with a discal dot 

 and median line. 



Habitat. Texas ; Wisconsin. 



Smaller than cinereola, with the markings much the same 

 but on a deeper and more diversified ground color. 



Eucalyptra, nov. genus. 



Eyes naked. The antenna? in the male are clothed with fine, isolated, 

 comparatively long hair. 



The first joint of the palpus is normally formed, the second and third 

 are united together to form a long (3 mm .), thin, distinctly triangular
