This genus comes near Zulcika Distant if that genus possesses the 

 spur of the Delphacini ; apart from the spur it approaches Malaxa Me- 

 lichar. 



N. flava sp. nov. 



$ Pale yellow-orange, eyes light brown, ocelli black, a longitudinal 

 brow^n mark down antennae not quite reaching the base of each joint. 

 Tegmina hyaline, milky white with waxy secretion, veins basad of cross- 

 veins concolorous, cross-veins and veins apical of cross-veins brown. 



Styles broad at base, gradually narrowing to apex, reaching to apex 

 of pygophor and covering the greater portion thereof. 



Length 2.4 mm. ; tegmen 3.6 mm. 



Hab. Majaguez, Porto Rico, July, 1914. Described from 

 two females, one in bad condition, in the American Mus. Xat. 

 Hist., Xew York. 



Genus Delphacodes Fieb. 

 D. erectus nigvipennis (Crawford)*. 



Megamelus erectus nigripennis Crawford, 1914. Proc. II. 

 S. Xat. Mils., Vol. 46, p. 625. 



One male specimen from Point a Pitre, Guadalupe, W. I. 

 This insect is very close to the brachypterous form of D. mata- 

 nitu (Kirk.) from Fiji and Papua. They are hard to distin- 

 guish except for the aedeagi, which are quite distinct (figs. 

 2, 3). D. erectus is most likely the macropterous form of ni- 

 gripennis and is paralleled by the light, macropterous form of 

 D. matanitu. 



D. mardininae sp. nov, 



$ ]\Iacropterous. Lateral pronotal carinae divergingly curved, not 

 reaching hind margin ; vertex square, carinae distinct ; face slightly nar- 

 rowed between eyes, sides subparallel, median carina simple ; antennae 

 reaching slightly beyond base of clypeus, second joint 1.5 times the length 

 of first; hind tarsi shorter than hind tibiae, first joint longer than other 

 two together, spur slightly shorter than first joint, laminate, subtectiform, 

 with minute teeth on hind margin. 



Head and thorax ochraceous.buff, abdomen ochraceous orange, carinae 

 of head and thorax lighter, face and clypeus between carinae slightly 

 fuscous, apical portion of each antenna! segment, apex of rostrum and 

 apices of tarsi brown. Tegmina and wings hyaline, veins fine, yellowish, 

 fuscous at apices, granules very small. 



Pygophor figured (figs. 4, 4a). 



Length 2 mm. ; tegmen 3 mm. 



*I propose the new name pscudonigripciutis for D. nigripennis IMuir.
