to that margin, and then followino; down the outer margin to its 

 broadest portion ; along the border the band is fully half the width 

 of the tegmina; but above this it narrows, and is not half so wide 

 as that in the upper area of the wing, along the lower edge of which 

 it sends a slender acuminate shoot much more than half way 

 toward the base ; the apical half of the remaining outer portion of 

 the wing is fuscous, and the part between fuligino-hyaline, with 

 black veins ; hind femora bi'ownish yellow or cinereous, broadly 

 bivittate with blackish, the base above and the apex also blackish; 

 hind tibia? blackish fuliginous at base, followed by a bi'oad con- 

 spicuous pallid belt; the rest of the tibise dark glaucous, merging 

 at either end into blackish fuliginous, the spines tipped with black.

PhlibOStroma (<p).{^a), rTT/xZ/m') nov. gen. 



Somewhat closely allied to Psinidia Stal, but with less angular ver- 

 tex, as seen from the side, and without any intersections of the ante- 

 rior half of the median carina of the pronotum. Head rather tinnid, 

 a little elevated, the summit arched, higher than the pronotum, the 

 eyes separated by a space at least double the width of the first joint 

 of the antennge; vertex pretty strongly declivant, shallowly sulcate 

 toward the angular apex ; lateral foveola? broad, transverse, some- 

 times scarcely separable from the parts below; ocelli touching the 

 eve at the extremity of its upper third; front but slightly declivant, 

 frontal costa rather narrow, narrowed above the antennae, sulcate 

 only below; eyes separated by fully their own length from the base 

 of the mandibles ; antennfe linear, in the female much longer than 

 the head and pronotum combined (those of male not seen). Pronotum 

 strongly contracted in the middle above, the lateral carinre, which 

 are slight though sufficiently distinct, having a clepsydra! outline; 

 disc nearly flat, the median carina very slight, distinct, equal, divided 

 once in the middle ; hind border roundly and rather obtusely angu- 

 lated ; tegmina surpassing tlie abdomen a little, rather slender.
