 joint not nearly reaching to tip of joint. Scales of eighth segment not fringed 

 on apical onedialf. Central tooth on labial plate bluntly rounded and not 



widely separated from the adjacent teeth U. sapphirina. 



Longest terminal spine scarcely two thirds the length of antenna, scarcely reach- 

 ing tuft ; secondary spine on terminal joint reaching nearly to tip of joint. Scales 

 of eighth segment with a fringe of uniform spines extending over apex. Cen- 

 tral tooth of labial plate sharp and distinct from the adjacent teeth. .U. socialis.

 NEW NOCTUIDvE FOR igo6.— NO. i. 



By John B. Smith, ScD., 

 New Brunswick, N. J. 



Leptina levitans, new species. 



Ground color dull sm^ky gray without contrasts. Head and thorax with a 

 whitish powdering, best marked on patagia, but not prominent on either of my ex- 

 amples. Primaries with the extreme base inferiorly a little paler but with no ap- 

 pearance of a white humeral spot and no defining or limiting line. Median space 

 superiorly ashen gray, and a slight gray powdering is visible throughout the space. 

 T. a. line barely traceable, a little irregular, with a small, somewhat even outcurve. 

 T. p. line sinuate., even, narrow, gray with smoky borderings, not well defined. S. t. 

 line very irregular, powdery gray, obscure, marked by obscure preceding dusky 

 shades and at costa by an obscure dusky cloud which does not reach the apex. A 

 series of dusky terminal spots. Orbicular wanting. Reniform of good size, almost 

 round, concolorous, ringed narrowly with brown and with a brown central dot. 

 Secondaries dirty yellowish or smoky, a little paler at base. Beneath, very pale smoky, 

 with an obscure outer line and discal spot. 



Expands. — i. 05-1. 12 inches = 26-28 mm. 



Habitat. — Ontario, Canada, A. H. Kilman ; Durham, N. H., 

 Weed and Fiske. 



One male and one female are now before me, in comparison with 

 three examples of L. dormitans with which I had in the past confused 

 this species. I have realized for some time that there were two forms 

 of Leptina without prominent white shoulders ; but supposed them to 

 be merely varying types of one species. The recent necessity for de- 

 termining a series of specimens caused me to compare more closely 

 and to resort to the original descriptions to determine the type form.
