 Isena Haw. 



Antenna inserted on the crown of the head, close to the eyes, 

 setaceous, rather short, clothed with scales above and pubescent 

 beneath in the males (1) ; more slender in the females. 

 Maxilla slender and spiral, scarcely so long as the antennae (3). 

 Labial palpi projecting nearly horizontally a little beyond the 

 head, and forming a short beak ; clothed with long scales, espe- 

 cially beneath, short at the apex (4) ; triarticulate, basal joint 

 very long and stout, curved at the base, 2nd not half so long, 

 ovate, truncated obliquely, 3rd small, ovate-conic (4 a). 

 Head small and round : eyes small and globose (7, the profile). Thorax 

 small and oval. Abdomen rather long and slender, tufted at the 

 apex in the male, loith an incurved acute claiv above and 2 compressed 

 lobes beneath ; conical in the female. Wings forming a triangle in 

 repose, superior elongate-trigonate, the apex slightly hooked, the 

 posterior margin a little angulated at the middle ; inferior ovate-tri- 

 gonate, the margin slightly loaved. Legs, anterior the shortest : 

 tibiae, anterior very short, intermediate terminated by long spurs as

When the genus Macaria was established eleven years since, 

 I consideretl the insects forming the genus before us were 

 closely allied to it, although they did not exhibit some of the 

 characters belonging to that group. In studying the Lepi-

 such important variations between the type of Macaria and 

 V. macularia that I very materially altered its situation ; and 

 upon a close examination I find the palpi, antennje, and hind 

 legs so essentially different from Macaria that I have no hesi-
