always pale toward base. Tlie metathorax is smooth, polished, 

 impunctured, not areolated, but with delicate side-keels. Abdo-

 the areolet entirely absent. 



Hal. St. Vincent. 



Described from 10 specimens, taken at an altitude of from 500 

 to 1000 feet. There may be more than one species ; but as the 

 specimens at hand are so few and badly mounted, I must leave 

 the question to be settled by future investigators. 



** Areolet present, pentagonal.

<S . Length 3 to 4 millim. Honey-yellow or luteous ; stem-

 posterior knees, tip of tibiae, and the extreme tip of the tarsal 

 joints fuscous ; rest of the legs white. Antennse 41-jointed, 

 pale, longer than the body, curled and fuscous at tips. Meta- 

 thorax rather long, the disk smooth, with two close, central, sub-

 metapleura are bounded by a keel, and the space behind the spi- 

 racles is a little roughened and almost enclosed by a carina 

 between the central longitudinal keel and the metapleural keel. 

 Wings hyaline, the venation pale brown, the stigma triangular ; 

 the areolet rather large, pentagonal. The two basal abdominal 

 segments are rough, the first with two longitudinal carinse above, 

 the second segment depressed at the middle, the following all
