104 JSfotes on North American Lepidqptera. 



piece, united to the first joint at its smallest angle, the side opposite this 

 angle being about one millimetre in length. The front is rounded ; above 

 and beyond the vertex the frontal villosity projects as a triangular tuft, 

 directed towards and almost reaching the obtuse angle of the palpal 

 piece. The thorax is weak, rounded and untufted ; its clothing entirely 

 ecaly. The abdomen is slight and closely scaled, exceeding the margin 

 of the posterior wings. 



The legs are long, closely scaled, having the tibiae non spinose. The 

 wings are elongate with all the angles rounded. 



This is a peculiar, slender-bodied genus allied to Amolita and Thauma- 

 topsis, the characters drawn from the palpi, antennae and frontal villosity 

 are very distinctive, and separate it at once from the genera mentioned 

 above, as well as all others known to us. 



Eucalyptra bipuncta, nov. sp. 



Expanse 31 mm . Length of body 14 mm . Palpi black. The front and 

 thorax whitish. The anterior wings are white, sprinkled with black at- 

 oms, outwardly they are gray and the atoms are more numerous. The 

 ornamentation is extremely simple, the two ordinary spots are reduced 

 to black dots; the median nervure is shaded with dark gray to the exte- 

 rior line; the latter is distinct, even, grayish-ochreous, regularly arcu- 

 ate beyond the cell and then extending obliquely to the inner margin ; 

 all other markings are obsolete. The abdomen and posterior wings are 

 uniform light grayish fuscous, with an ochreous tinge. 



Beneath, the .anterior wings are dark gray, with a distinct ochreous 

 costal border ; the posteriors are lighter, grayish ochreous with a dark 

 costal border. 



Habitat. Massachusetts. 

 Taken at Belmont, Aug. 17, 1874. 



The slight form, the obsolete markings, and the triangular 

 black palpi will serve to identify this species.
