yellow, legs pale, femora scarcely darker. Head plainly constricted 

 as in C. antillaruvi, sparingly clothed with short hairs, and among 

 them a few longer ones, nose slender, as long as width of head at con- 

 striction, hairy at tip; antennae long, third joint plainly longer than 

 second, fourth, fifth, and sixth, and beyond as long as third, more 

 than twice as long as broad. Abdomen with short hairs, and longer 

 bristles on margin of segments. Length of head 1.2 to 1.3 mm. 



Closely related to C. aniiUarum, but the very pale head distinguishes 

 it; in numerous specimens of both forms I have seen no intermediates. 



CONSTRICTOTERMES TOUSSAINTI, Sp. nOV. 



Type.— M. C. Z. 10,082. Haiti :— Milot, January (Mann). 



Soldier. — Head brown, not especially dark, nose black; antennae 

 brown, as dark as head; abdomen brown above; femora and tibiae 

 more or less infuscated, especially the front femora. Head con- 

 stricted, but not as much as in C. aniiUarum, clothed with fairly 

 numerous short hairs; antennae short, second joint fully one half 

 of the first, third no longer than second, fourth plainly longer than the 

 third, joints beyond are short, hardly twice as long as broad, much 

 shorter than in C. antillarum; abdomen with short hair, few longer 

 bristles on tips of segments; nose hardly as long as width of head 

 at constriction. Head 1.3 mm. long. 



Constrictotermes flaveolus, sp. nov. 



Type.— M. C. Z. 10,083. Haiti :— Petionville, November ; (also 

 taken by Dr. Mann at St. Marc, January, Ennery, January, and 

 Manneville, December (Mann). 



Soldier. — Head pale yellowish, nose darker, more reddish; abdo- 

 men yellowish above; legs and antennae whitish. Head only a trifle 

 constricted, but by careful observation from in front it is seen to be 

 slightly so; clothed above all over with fine, short hair; antennae 

 short, the third joint no longer than the second, fourth and fifth no 

 longer, sixth and beyond rather longer, but not twice as long as broad. 

 Nose slender, about as long as width of head at constriction, fine 

 hair also on the nose. Abdomen with short hair. Length of head 

 1 mm. 



Differs at once from A", ripperti {cuhanus) in the very much smaller 

 head with much shorter and more numerous hairs, in hairy nose, and 

 horter third joint of antennae.
