1891.] MICRO-LEPIDOPTERA OF THE WEST INDIES. 535 



dots beyond the end of the cell, and a slight angulated fuscous shade 

 before the apex running parallel to the margin of the wing (in some 

 specimens these markings are almost obsolete) ; cilia cinereous. 



H'md wings greyish ; cilia cinereous. 



Abdomen cinereous, faintly banded with a deeper shade. 



Legs : hind tibise fuscous, externally clothed above with pale cine- 

 reous hairs ; spurs and tarsal joints pale cinereous. 



Exp. al. 10-12 millim. 



Hab. West Indies — St. Vincent (Kingstown, 2 specimens ; wind- 

 ward side, 6 specimens, Smith).

In markings this species is scarcely distinguishable from a small 

 specimen of Blastobasis phycidslla, 7i., but the absence of an an- 

 tennal notch and the neuratiou of the hind wings at once distin- 

 guish it. It is the only form allied to Blastobasis that I have yet 

 met with in which veins 3 and 4 of the hind wings proceed from a 

 stalk out of 3 instead of coming direct from the edge of the cell ; 

 the whole group is an exceedingly difficult one, and the multiplica- 

 tion of genera founded on good structural differences, however slight, 

 can only facilitate their future classification, especially as the species 

 are at least as difficult to separate by pattern and markings as are 

 the genera. 



HjELIOBININM. 



Heliodines, Stn. 

 Heliodines marginata, sp. n. 



Antennae simple, as long as the fore wings ; sooty brown. 



Palpi short, slender, dependent ; sooty brown. 



Head and thorax sooty brown ; underside of the thorax with a 

 conspicuous orange yellow spot on each side. 



Fore wings shining orange-yellow, very narrowly margined through- 

 out with sooty brown, which is diffused over the extreme apex ; a 

 single lilac shining metalUc spot lies on the costal margin near the 

 base ; there are two slender, but by no means conspicuous, streaklets 

 of the same colour — one along the base of the ciUa about the 

 region of the anal angle, the other much shorter, above and parallel 

 to it, forming a short tooth-like projection inwards from the middle 

 of the suffused dark apical portion of the wing ; cilia sooty brown. 

 Underside unicolorous greyish brown. 



Hind wings deep brown ; cilia sooty brown. Underside unicolor- 

 ous greyish brown. 



Abdomen and legs sooty brown. 



Exp. al. 8 millim.
