OP THE ISLAND OF ST. TINCENT. 235' 



transverse, the vertex with a delicate transverse carina behind 

 tlie ocelli; the lateral ocelli not more than twice their 

 width from the margin of the eye. Antennae hlack ; the f unicle 

 slender, the first joint loDger than the pedicel ; club slender, 

 the joints all longer than thick. Thorax convex, without furrows- 

 Scutellum depressed at base, and produced into a long acute 

 yellow spine. Mesopleura, except just beneath the tegulse, 

 which is striate, smooth, shining. Metapleura bare and 

 smooth, bounded by a carina above ; the lower half of the carina 

 with a fringe of pale pubescence. Metathorax with a prominent 

 yellow median carina. Wings hyaline. Legs black ; the tro- 

 chanters and base of tibiae pale brown ; tarsi yellowish. Body 

 of abdomen oval, smooth, impunctured, with a tuft of pubescence 

 at base beneath; petiole longer than thick, impressed at the 

 middle, fluted, subpubescent at apex and beneath. 



Sab. St. Vincent. 



Described from a single specimen. 



Ambltaspis vebticillatus, sp. n. 



6 $ . Length 1-5 millim. Polished black, impunctured ; the 

 mesopleura with no striae beneath the tegulse ; scutellum pro- 

 duced into a long, acute, yellow spine. Antennae and legs 

 honey-yellow ; club piceous, the joints very long, subclavate, as 

 long as the basal joint of tarsi, and witb wborls of long hairs ;. 

 funicle long, slender, cylindrical, the second joint more than 

 twice as long as the pedicel, the first joint short. Wings 

 hyaline. Body of abdomen oval; the petiole about twice as long 

 as thick, depressed at the middle, fluted, subpubescent. 



The female agrees well with the male, except that the antennae 

 end in a 4-jointed black club, the joints of which are only 

 slightly longer than thick ; the funicle is long, slender, and 

 cylindrical, the first and second joints being about equal and as 

 long as the pedicel ; the extreme apex of posterior femora and 

 tibiae obfuscated or brown ; while the lateral ocelli are only their 

 width from the margin of the eye. 



Hah. St. Vincent. 



Described from one male and one female. 



No male is described in this genus witb similar antennae, and 

 no difiiculty will attend its recognition. It is doubtful whether 

 the female correlated here is the opposite sex of this species.
