RETICULITERMES FLAVIPES Kollar. 



Winged. — Hard parts brown to blackish, always darker on head 

 and thorax than on the abdominal segments; legs beyond femora 

 whitish; last joint of palpi barely if at all marked with dark. Head 

 about as broad as long; margin of labrum a little emarginate; eyes 

 about circular, each about its diameter from the lower margin; 

 ocelli more than diameter from eye, and as far from the lateral fene- 

 strae; latter semielliptic, fairly distinct, and much larger than the

 mandibles about as long as width of head; gula about two and a half 

 times as broad in front as at middle. Pronotum nearly semicu-cular,
