XI. D, 6 Muir: Additions to Delphacidx (Hemiptera) 371 



Length, 4.5 millimeters ; tegmen, 5.3. 



Female. — Slightly darker in color, similar in size. 



Luzon, Mount Maquiling and Baguio (Baker-) . 



This species can be distinguished from M. granulata Melichar 

 by the dorsal color pattern ; by the medioventral process of py- 

 gophor being longer, narrower, and more acute at apex; and 

 by the genital styles being much straighter. 



Genus PTJNANA Muir 

 Punana MuiR, Proc. Hawaiian Ent. Soc. (1913), 2, 249. 



This genus has a single, simple median carina on face.- 

 Punana philippina sp. no v. 



Male. — Light brown; gense and face below eyes lighter; legs 

 and ventral surface lighter, legs marked with small dark bands. 

 Tegmina yellow or light brown, minute brown granules irregu- 

 larly arranged along the veins, also in the cells; apical veins 

 slightly infuscate at margin ; wings dark fuscous with darker 

 veins. 



Pygophor long, opening ventrad, ventral edge forming a deep, 

 round emargination with a minute, angular projection in the 

 middle; lateral edges also roundly and deeply emarginate, form- 

 ing a projection on each side of anal segment; anal segment 

 large, convexo-concave, about as broad as long, sides slightly 

 arcuate, apex subtruncate, anus in middle on raised area; styles 

 slightly flattened, broadest at base, apex subacute, basal two 

 thirds straight, at an angle to apical third. 



Length, 3.5 millimeters; tegmen, 4.5. 



Luzon, Laguna, Mount Banahao (Baker). 



Pimana negrosensis sp. nov. 



Male. — This species differs from P. philippina in having the 

 front and middle coxae and femora darker brown, a small fus- 

 cous spot in clavus, and fuscous over cross veins and along 

 media to apex. 



Pygophor similar in shape to that of P. philippina, but the 

 medioventral process square with corners minutely produced, 

 lateral edges without produced processes along edges of anal- 

 segment; anal segment with shallow emargination at apex; 

 styles sickle-shaped, basal fifth straight, apical four fifths curved, 

 apex pointed. 



' I wrongly stated that this genus possesses two frontal carinae. Ca»i.
