OF THE ISLAND OF ST. VH^CENT, 149 



three times as long as the 4th, the following with sparse white 

 hairs. 



The male agrees with the female, except in having the coxae 

 black ; flagellum very long, black, the funicle-joints 1 to 5 

 strongly pedicellate at apex, with two whorls of long white hairs, 

 the first joint being the longest, fully two thirds the length of 

 the scape ; joints 8 and 9 separated by a constriction ; petiole 

 long, one half longer than the hind coxae, uniformly and con- 

 fluently punctate ; body of abdomen smooth, polished, the third 

 segment (excluding the petiole) the longest, fully twice as long 

 as the second, the first longer than the second, with a large fovea 

 at base above. 



Sal. St. Vincent. 



Described from 1 female and 8 male specimens. 



Ettettoma peeaffinis, sp. n. 



S. Length 2'5 millim. Closely allied, to E. insularis, but 

 differs as follows : — The scape is pale only at base beneath ; the 

 pronotum has a yellow spot at the angles anteriorly, and easily 

 overlooked if the head is thrown back on the collar ; hind femora, 

 except at tips, black ; petiole much longer than the hind coxae, 

 smooth towards apex and along the sides, finely punctate towards 

 base ; while the third body-segment of the abdomen is more than 

 twice as long as the second. 



A female specimen of what is undoubtedly the opposite sex of 

 this species, without a head, agrees in all essential characters with 

 the male, except that all the femora toward base are more or less 

 dusky or black ; as in the male, it shows a pale spot on the angles 

 of the pronotum anteriorly ; the abdomen is shaped much as in 

 the female insularis, only it is black, except just at base beneath, 

 and shows a very delicate wavy lined sculpture along the sides 

 under a strong lens. 



Sal. St. Vincent. 



Described from one male and one female. 



Distinguished by the pronotal spot, more frequently met with 

 in the genus Isosoma. 



Ettettoma mactjliventeis, sp. n. 



S 2 . Length 2-5 to 3 millim. Brownish yellow ; teeth of 

 mandibles 4-dentate ; flagellum, stemmaticum (especially in the 

 male), median stripe on collar, middle lobe of mesonotum, meta-
