and close to eye. Labrum yellow-brown, somewhat ton^i^ue shaped,

 first segment long, stout, cylindrical; second shorter than first, more 

 clavate; third somewhat darker colored, shorter than second, clavate; 

 fourth short, about half as long as third, ringlike; fifth longer than 

 fourth; antenna becomes gradually wider towards apex. 



Pronotum slightly paler than head, broader, anterior corners 

 turned down, anterior margins deeply concave, posterior margin 

 plainly emarginate, nearly twice as broad as long, shorter than wing 

 scale, long hairs on margins. Pronotum and wing scale longer 

 than in N. connexus Snyder. 



Abdomen with longer hairs than in connexus. 



Legs with femora more enlarged than in connexvs. 



Measurements. 



Length of entire deiilated adult: 10.75-11.0 nun. 



Length of head: 2.35-2.4.'5 mm. 



Length of pronotum : l.oO nun. 



Length of hind tibia : 1.70 nun. 



Width of head (at eyes) : 1.95-2.0.5 mm. 



Diameter of eye: 0.40S mm. 



Width of pronotum : 2..35+-2.45+ mm. 



Soldier unknown. 



More material is needed to determine whether this is merely a 

 variety of N. connexus or a distinctive species. It is darker colored, 

 larger, head and pronotum larger than in connexus; pronotum with 

 po.sterior margin plainly emarginate; pronotum and wing scale with 

 more numerous and longer hairs. The third segment of the antenna 

 is longer and more clavate than in X. connexus; the last segment 

 of the maxillary palpi is longer. 



Tijije locality. — Kaiwiki, Hawaii, Territory of Hawaii. 



Described from two dealated adults collected at the type locality 

 by W. H. Ashmead in July ; Ace. No. 38341. Kaiwiki is near Kilo — 

 being a few miles above— at an elevation of 610 to 915 meters (-2,000 

 to 3,000 feet).

Genus CRYPTOTERMES Banks. 



In 1906, Nathan Banks created the genus Cryptoterm^s for a 

 termite from Florida, the soldier of which has a uniquely cavate 

 head {C . cavifrons). Until recently this has been a genus of com- 

 paratively few known species. These are of local distribution, being 

 apparently restricted to the Tropics or subtropical regions. There 

 are several new species from the West Indies and South America.
