OP THE ISLAND OF ST. TINCENT. 81 



first abdominal segment with short yellowish pile, which is very- 

 abundant at tip of mesoscutellum ; on second abdominal segment 

 this pile is present only in two dorso-lateral patches, but in 

 following segments there is a deep fringe from the border of 

 each ; hind femora with 11 teeth below, first and eleventh 

 largest, the others well separated, except 8, 9, and 10, which are 

 shorter and close together. Colour black ; tegulse, with the ex- 

 ception of three minute black spots, bright yellow ; apical third 

 of front and middle femora bright yellow, the line of juncture 

 between the black and the yellow on the outer surface oblique : 

 front and middle tibiae yellow except a black patch on the outer 

 middle ; all tarsi yellow ; hind femora with a single rather large 

 yellow patch at upper tip extending into the black of the outer 

 surface for a little over one fourth the length of the femur ; hind 

 tibiae black at base and with a sharp black band a little beyond 

 middle, being thus divided approximately into alternate black 

 and yellow fourths ; wings hyaline, veins dark brown except 

 basal half of submarginal vein of hind wings, which is bright 

 yellow.

There is some doubt both as to the generic and specific placing 

 of this form, which is represented in the St. "Vincent collection 

 by 29 males and 35 females. It corresponds closely with the very 

 brief diagnosis of the genus given by Kirby (Linn. Soc. Journ., 

 Zool. xvii. p. 63), but this description is incomplete, and the types, 

 Halticella fascicornis, Walk., and S. diversicornis, Walk., be- 

 long to the South Asiatic fauna. It is plainly distinct, however, 

 from any other Chalcidine genus, as defined by Kirby. It is 

 the female antenna which is figured and described by Kirby. 

 That of the male differs considerably. It is apparently only 11- 

 jointed, since but one dividing suture in the club can be seen. 

 The scape is much shorter, being less than one fifth the length 

 of flagellum, and reaches only to middle of eyes. The pedicel is 

 very short, about as broad as neck of scape, and about as long as 

 broad. Joint 1 of funicle is suddenly broader, nearly twice as
