and deep fovea on each side of median line in rear center, elevated 

 slightly on postoceUar regions; gense large, rather prominent; frons 

 usually mostly covered by gense but not entirely, visible as a small 

 sclerite. Antennae about twice as long as width of head. 



Thorax arched, coarsely punctate, shghtly pubescent. Pronotum 

 rather long, flat; propleurites long and narrow; prsescutum short. 

 Wings small, hyahne, about two and one-third times as long as broad, 

 broadly rounded at apex or somewhat squarish; first marginal cell 

 larger than second; pterostigma rather long, and broad at base, 

 yellowish. 



Genitalia. — Male. — Genital segment small, rounded; forceps longer 

 than anal valve, elhptical in profile, with a short narrow pedicel, 

 rather flattened, with a long spiniform process arising from inner 

 surface near base and extending backward and upward along posterior 

 margin of forceps to near apex. Anal valve short, rather cylindrical, 

 truncate at apex, sometimes nearly as long as forceps. — Female. — 

 Genital segment almost as long as rest of abdomen, acute at apex, 

 dorsal valve longer than ventral. 



Described from numerous males and females collected at Havana, 

 Cuba, by C. F. Baker, occurring in great numbers on Leucaena glauca; 

 several specimens in the U. S. National Museum collection from 

 Santiago de las Vegas, Cuba (P. Cardin), on Poinciana regia, December 

 29, 1910. Both plants belong to the Leguminosae, the former being 

 closely related to Mimosa, which is the food plant of another species 

 of this same genus, in Texas.

HETEROPSYLLA QUASSIA, new species. 



Figs. 113, 117. 



Length of body 1.5 mm; length of forewing 1.7; width of head 

 0.72. General color light j^ellowish orange to orange, vertex and 

 dorsum of thorax sometimes brown, always more or less distmctl}'' 

 strigate. 



Head and thorax similar in most respects to the following species 

 (Jusca). Forewings seldom fumate, sometimes very slightly so, 

 usually clear. Male genital segment not as small as in fusca; forceps 

 as long as anal valve, strap-shaped, curved inward at apex, tip 

 rounded, black, sides parallel; with a short process on posterior side 

 near middle, extending upward and inward for a short distance. 

 Anal valve moderately long, of usual cylindrical shape. Female 

 genital segment as m fusca. 



Described from two males and seven females from the Bahama 

 Islands, some of them from Nassau Island (Schwarz), March 27, 1879; 

 and the rest from Long Island, April 3, 1879, on Quassia sp.
