KEY TO THE SPECIES OP SACANDAGA. 



1. Length, 5 mm.; wing, 6-7 mm.; color of the body, yellowish; wings, hyaline. 



/aw Alexander ' (Eastern II. S.). 



Length, 2. 9-4. -5 mm.; wing, 4-5 mm.; color of the body, brown; wings, gray. 



• parva, new species (Greater Antilles). 



SACANDAGA PARVA, new species. 



Antcnnse brown; color of body brown; wings gray. 



Male. — Length, 2.9 mm.; wing, 4 mm. Head: rostrum and palpi 

 dark brown; antennie dark brown, the first flagellar segment elon- 

 gated. Eyes widely separated by the very broad front and vertex; 

 front, vertex, and occiput dark blacldsh-brown with an indistinct 

 sparse gray bloom. 



Thorax: pronotum barely visible from above, dark brown, the 

 sides of the scutellum more j^ellowish ; mesonotum, praescutum rather 

 dark brown; space in front of the pseudosuture more yellowish; 

 pseudo-sutural fovea deep, shiny, dark brownish-black, elongate 

 semilunar; tuberculate pits dark brown, far cephalad, nearer the 

 anterior margin of the sclerite than to the pseudo-suture, separated 

 from one another by a distance equal to about one and one-half the 

 diameter of either; scutum, scutellum, and post-notum dark brown, 

 pleurse grayish-brown, region about the wing basis yellowish. Hal- 

 teres 3'ellow at basis, stem and knob brownish; stem with long 

 brown hairs. Legs: coxae and trochanters dull yellow; femora, 

 tibia, and tarsi dark brown. 



Wings: gi'ay throughout, costal cell more brownish; veins brown. 

 Venation (see fig. 9) : Sc quite long, its distance beyond the origin 

 of Rs about two and one-half times the length of cross vein r-m. 

 Sc2 rather indistinct, far removed from the tip of Sc,. R rather 

 long, however, the tips of R, and R, are much more widely separated 

 than in S. fiava. Rs long, gently arcuated; R2+3 much longer 

 than cell R,; R3 is missing in its distal portion (an abnormity 

 rather than a specific character); R, short, almost perpendicular; 

 cross vein r-m and the basal deflection of R^+s subequal. Basal 

 deflection of Mi+, practically gone, M being almost in a line with 

 Ml..;; second anal long bisinuat^d. Cell first M, not so regularly 

 hexagonal as i\\ fiava, anal angle very prominent. 



Abdomen: tergum dark brown, sternum brownish-yellow on basal 

 five segments.
