ABT.6. NEW SPECIES OF TERMITES — SNYDER. 11 



shorter than the outer, another row of hairs is on the anterior of the 

 head. 



Antennae light yellow-brown, 10 or 11 segments, a little longer 

 than mandibles, with long hairs, segments become broader toward 

 apex; first segment elongate, cylindrical; second shorter than first, 

 not clavate; third longer than second, clavate, appears to be divided 

 near narrow base, latter however with no hairs; fourth broader, 

 shorter than third; last segment elongate, subelliptical. 



Eyes pale, large, elongate, subelliptical, near antennal socket. 



Labrum yellow-brown, longer than broad, somewhat tongue- 

 shaped, rounded at apex, with 2 long hairs (longer than labrum) set 

 in center of apex, also with shorter hairs. 



Mandibles blackish, short, not as long as width of head, broad at 

 base, pointed and incurved at tips; 2 pointed, small marginal teeth 

 near tip and a broader tooth near base on left mandible; right 

 mandible with 2 broader marginal teeth nearer base (pi. 1, fig. 3). 



Gula elongate, narrowed in center, not twice as broad at front as 

 in center. 



Pronotum paler than head, twice as broad as long, anterior and 

 posterior margins nearly parallel, anterior corners high, sides rounded, 

 gradually slope to posterior, with long, light-yellow hairs on margins 

 (pi. 1, fig. 4). 



Legs with tibiae and tarsi yellowish, fairly elongate, femora 

 thickened. 



Abdomen gray-white, with long, dense, light-yellow hairs. 



Measurements. — ^Total length of soldier, 5.5-6.5 mm.; length of 

 head with mandibles, 2.4-2.5 mm.; length of head without mandibles, 

 1.8-1.9 mm.; length of left mandible, 0.85 mm.; length of pronotum 

 (at corners), 0.65-0.80 mm.; length of hind tibia, 0.57-0.705 mm.; 

 width of head, 1.2-1.4 mm.; width of pronotum, 1.1-1.4 mm. 



Described from 2 soldiers found with the typical dealated adult. 



The genus Glyptoterrries Froggatt has not been previously recorded 

 from the Antilles. 



Type locality. — Aibonito, Porto Rico. 



Described from several dealated adults collected at the type 

 locality from partly dead coffee tree on December 2, 1921, by F. Sein 

 and George N. Wolcott, Ace. No. 488-'21; 2 soldiers and nymphs 

 were found with these dealated adults. 



Type, dealated adult.— Cat. No. 25415, U.S.N.M. 



Biological. — The burrows of G. pubescens in a partly dead coffee 

 tree at Aibonito, Porto Rico, in dry, hard, sound wood (pi. 2, figs. 

 11-12) are similar to those of Cryptotermes. The impressed pellets of 

 excrement are small, more elongate, irregular in shape and are 

 pointed at the apex, as an apple seed (pi. 2, fig. 13).
