OP THE ISLAND OF ST. VINCENT. 119 



the first segment, basal two-thirds or more of the second, basal 

 half of the third, and the fourth slightly at base longitudinally 

 striated or aciculated ; rest of the abdomen smooth, polished. 



The male, which is very variable in size and colour, is usually 

 pale or ferruginous, although sometimes presenting an exact 

 colour-pattern of the female. Sometimes it is wholly pale, with 

 only the metathoras, first abdominal segment, and two or three 

 of the following segments dusky ; the basal portion of the second 

 segment, however, is always more or less distinctly yellow, and 

 the sculpture is identical, or nearly so, in both sexes. The 

 antennae vary from 22- to 29-jointed. 



Sab. St. Vincent.

Heteeospii;TJS pai/Lidipes, sp. n. 



(S 2 ' Length Ik to 3 millim. ; ovipositor a little longer than 

 the abdomen. Pale ferruginous ; orbits, lower part of head, 

 streak on collar, and legs white or luteous. Collar, humeri, meso-

 Eyes very large, rounded, slightly sinuated within. Thorax 

 finely shagreened, the furrows distinct, the middle lobe pos- 

 teriorly in front of the scutellum with three or four raised lines ; 

 scutellum smooth, polished ; metathorax areolated, rugose, the 

 surface of the two large basal areas finely, closely punctate, the 

 diamond-shaped area nearly obliterated by the rugosity of its 

 surface. AVings subhyaline, the venation brown, the first and 

 second transverse nervures subobsolete. Abdomen not longer 

 than the head and thorax together ; the second segment longer 

 than the first, with two transverse impressed lines, the first at 

 about half its length, the second at about one-third the length of 

 the remaining half ; the third segment also with a transverse, im- 

 pressed line ; the first segment and the basal half of the second 

 longitudinally striated, the transverse impressed line on third 

 aciculated at bottom; rest of the abdomen smooth, polished.
