18 PKOCEEDINGS OF THE NATIONAL MUSEUM vol. CS 



sides roundly but gradually narrowed to posterior margin, markings 

 on pronotum similar to those in C . (C .) aclgtmthus Silvestri, with 

 dense long hair. 



Wings hyaline, costal area golden-yelloAV-brown, surface with nu- 

 merous long hairs, margins ciliate. In forewing median nearer to 

 cubitus than to sub-costa, branches down (5-7 sub-branches) before 

 middle of wing, but forked to apex of wing, cubitus with 9-10 

 branches to lower margin of wing, only extends but a little beyond 

 center of w^ing. In hind wing fewer sub-branches to median vein and 

 cubitus extends further, has more branches and covers a wider area 

 of the wing. 



Legs yellow-brown, tibiae darker, elongate, slender, with long 

 hairs. 



Abdomen with tergites same color as head, two hyaline, slightly 

 reni-form markings placed as in acigncdhus^ but not as clear, with 

 long hairs near base tergites, cerci not prominent. 



MeoHurerrhents. — 



Length of entire winged adult, 17.50 mm. 



Length of entire deJilated adult, 8.00 mm. 



Length of head (to tip of labrum), 1.90-2.00 mm. 



Length of pronotum (to anterior corners), 1.05 mm. 



Length of fore wing, 16.50 mm. 



Length of hind tibia, 2.30 mm. 



Diameter of eye (long diameter), 0.50 mm. 



Width of head (at eyes), 1.90 mm. 



Width of pronotum, 1.70 mm. 



Width of fore wing, 4.30 mm. 



The winged adult of G. {C.) holivianus Snyder has a wider head 

 and pronotum and the ocelli more distant from the eyes than in 

 G. (G.) strlatus Hagen; it has smaller eyes than acignathus Silvestri 

 and narrower head and pronotum. There are marked differences in 

 the sexual winged adults within the species in the genus G oimitermes. 



Soldier. — Head yellow, darker anteriorly, broadest posteriorly, 

 tapers (narrows) anteriorly, frontal tube slightly darker, elongate,

 rowed, with long hairs. 



Mandibles blackish, fairly elongate and slender, sharp pointed 

 apices incurved, marginal teeth on left mandible small (pi. 1, fig. 4), 

 no marginal teeth on right mandible.
