NASUTITERMES (NASUTITERMES) MINOR Holmgren 



Winged adult. — Head castaneoiis brown, with dense long hairs. 

 Fontanelle a slender hyaline slit forming with the epicranial suture 

 a hyaline Y-shajDed marking. Post clypeus yellow, slightly less than 

 three times as broad as long, with dense long hairs. 



Eye black, not round, projecting, close to lateral margin of head.

 toward apex, with long hairs; third segment subclavate, slightly 

 shorter and narrower than second and fourth segments; fourth 

 shorter than second ; fifth shorter than fourth ; last segment elongate, 

 narrow and subelliptical. 



Pronotum light yellow-brown, saddle-shaped, sides obliquely slope 

 to posterior margin which is emarginate, with dense long hairs. 



Meso- and meta-nota broadly emarginate, nearly straight, whereas
