rather brown on front edge, rest and abdomen above yellowish; 

 antennae also yellowish; legs pale. Head broad, and plainly a little 

 flattened across vertex, seen from in front; nose large and very long, 

 in side view about as long as head; two long bristles near vertex, 

 extremely small ones below at base of nose, hardly noticeable; else- 

 where on head are extremely minute hairs, scarcely visible; pronotum 

 with only short hairs on margin ; abdomen with short hair, and longer 

 erect bristles on hind margin of segments; antennae long, third joint 

 plainly longer than the second, fourth and fifth joints shorter than 

 third, about equal to second, others beyond rather longer. Length 

 of head 1.7 mm. 



Lives in a small nest on ground. Near to X. surinamejisis Holmgren, 

 but no long hairs at base of nose nor on margin of pronotum, and 

 vertex not as convex, and color paler than in that species. 



Xasutitermes morio (Latreille). 



This species is common over the entire West Indian area, and a 

 form almost the same (^V. cornigera Motschulsky) occurs in Panama. 

 Holmgren has described the adult as E. costalis; but all specimens 

 do not show the pale area in the wing; the soldier is described by 

 Holmgren as E. hatiencnsis; his E. martiniqiiensis is also the same, 

 and also E. sandae-luciae. Adults and soldiers have been taken in 

 the same nest in various cases. 



As might be expected, a common and widely spread species shows 

 some variation. The distance of the ocelli from the eyes varies 

 somewhat, and in the soldier the length of the nose, and the compar- 

 ative length of the third joint of the antennae also varies; however, 

 after examining thousands of specimens I can find no definite char- 

 acters to separate races or subspecies and am much inclined to include 

 under this species the N. sanchezi of Holmgren.
