nearly in a straight line; the nasus is cylindrical, but slender. The 

 mandibles of the soldier caste, as a rule, are absent. The post- 

 clypeus is large. 



NASUTITERMES (SUBULITERMES) ZETEKI. new species. 



Soldiers (pi. 4, figs. 25-26). — Head pale yellowish, nasutiform, 

 pear-shaped, elongate, but narrow, tapers anteriorly, where slightly 

 thicker (higher), with dense long and short hairs; nasus castaneous- 

 brown, elongate, narrow, straight, with dense short hairs even to 

 apex and on both dorsal and ventral surfaces. Mandibles absent. 



Antennae Vviiite with tinge of yellow, 11 segments, pubescent, 

 segments become broader and longer toward apex; first segment 

 elongate, broad, cylmdrical; second shorter than first; third sub- 

 clavate, slender, slightly longer than second or fourth, also slightly 

 narrower; fourth subclavate, slightly longer than second; last seg- 

 ment elongate, slender and subelliptical. 



Pronotum white with tinge of yellow at anterior margin, saddle- 

 shaped, not nearly as broad as head, with long hairs. 



Legs white with tmge of yellow, fairly elongate, slender, pubescent. 



Abdomen grayish-white with tmge of yellow, with dense short 

 light yellow hairs on both dorsal and ventral surfaces and long hairs 

 at each side at the base of each segment. 



Measurements. — Length of entire soldier, 2.2-3.1 mm.; length of 

 head with nasus, 0.95-1.1 mm.; length of head without nasus, 0.6- 

 0.7 mm.; length of nasus, 0.35-0.3S mm.; length of pronotum, 0.11 

 mm.; length of hind tibia; 0.45-0.50 mm.; width of head, 0.42-0.46 

 mm.; width of pronotum, 0.27 mm. 



This small, hairy, species of Subulitermes is the first to be found in 

 Central America; it differs from the two known South American 

 species as well as from undescribed species from South America in 

 the collection of the United States National Museum. S. zetelci is 

 smaller and has more longer hairs on the head than either S. micro- 

 soma Silvestri or incola Holmgren. It also differs from 6 undescribed 

 species from South America, which will be described by A. Emerson 

 and F. Silvestri; only one other of these 2 described and 6 unde- 

 scribed species of Subulitermes from America consistently has 11 

 segments to the antennae. 



Winged adult unknown. 



Type locality. — Summit, Canal Zone, Panama. 



Described from a series of soldiers found with workers at the type 

 locality by J. Zetek and I. Molhio (Z. 1731), on July 29, 1922, abun- 

 dant, in the trunk and petiole of an oil palm {Eleas melanococca)
