Genus DISTANTINIA novum 



Differing from Leomelicharia in the neuration of the tegmina. 

 The cubitus arises from the median vein about one fourth from 

 base ; thus there are only two longitudinal veins in basal portion 

 of tegmen. 



Distantinia nigrocacuminis sp. nov. Plate I, fig. 5. 



Brown; carinse of vertex and pronotum, hind margin of me- 

 sonotum, edge of tegulse, legs, genitalia, and small spots on ab- 

 dominal tergites lighter. Tegmina hyaline, apical fourth dark 

 fuscous with four white spots, the dark color continuing on 

 costal and subcostal cells to middle of tegmina, another dark 

 mark at junction of clavus with media, and a smaller one at ex- 

 treme base; hind margin excavate at apex of median sectors, 

 making the margin sinuate; veins reddish, especially the costa 

 and the transcostal and apical veins; wings minute, triangular, 

 fuscous, lighter on hind margin; stridulating area large. 



Male. — Lateral edges of pygophor dravni out into acute an- 

 gles ; anal segment a little longer than broad, apex rounded, anal 

 style about as long as segment, arising from ventral part of 

 apex of segment; genital styles not reaching to end of lateral 

 processes, acutely angular, attached to pygophor by one corner 

 of base, apex subacute. 



Female. — Posterior edge of pregenital sternite produced as 

 a subspatulate process, depressed along middle; lateral plates 

 well developed, ventral plate circular, dorsal plate subangular 

 with obtuse apex; between them lies a small bifurcated sclerite 

 (belonging to basal plate?). 



Length, 1.8 millimeters; tegmen, 5. 



Luzon, Laguna, Mount Maquiling (Mtiir), on palm trees; 

 cotype in College of Agriculture, No. 18130. 



In general appearance this is very much like Leomelicharia 

 nigrovittata Muir, but the white spots in the black apex of the 

 tegmina constitute a well-marked character, 



RHOTANIN.^ 



The subfamily Rhotaninse, as now constituted, contains six 

 genera {Decora, Levu, Rhotana, Genestia, Sumangala, and Mecij- 

 norhynchus), but they are ill defined. There are still a few 

 undescribed species before me, but I do not feel justified in 

 naming them until I can define the genera more definitely.
