March. 19 n] GiRAULT : New SpECIES OF POLYNEMA. 13 



usual cvirved, transverse line of fovea at distal two thirds and at its base a 

 transverse line of slightly elongated fovese along the division between the 

 scutum and the scutellum. Mesoscutum and scutellum with barely perceptible 

 sculpture but present as fine polygonal figurations. 



Antennae 9-jointed, apparently naked but under high power (one sixth inch 

 ■objective) a few scattered sets are present ; hispid as in mactdipes Ashmead 

 ■when unmounted. The scape is ovate, widest at distal third, slightly longer 

 than the pedicel and first funicle joint combined but not more than three fourths 

 the length of the abdominal petiole, slightly longer than joint 3 of the funicle ; 

 pedicel shorter, slightly more robust, subpyriform, a third longer than the 

 following joint ; the latter (joint i of funicle) distinctly the shortest antennal 

 joint, cylindrical, a third the length of funicle joint 2 or 3 ; joints 2 and 3 of 

 the funicle subequal, distinctly the longest funicle joints, joint 2 slightly longer 

 than 3. both cylindrical and subequal in length to the scape but much slenderer 

 and distinctly shorter than the club and but a fourth as wide ; funicle joint 4 

 shortened and very slightly thickened, but two thirds the length of joint 3 and 

 slightly shorter than joint 5 ; the latter more thickened, slightly longer, rectan- 

 gular, subequal in length to joint 6 of the funicle and about a third wider than 

 joint 3 or 4 : the distal or sixth funicle joint is no longer but wider, elliptical- 

 ovate, not quite half as wide as the greatest width of the club but of nearly 

 the same shape, not quite as wide as the scape ; club forming an enlarged ovate 

 mass which is slightly longer than the combined lengths of funicle joints 5 and 

 ■6, distinctly the largest antennal joint ; undivided ; along its sides and extend- 

 ing from the apex proximad are a few short, longitudinal grooves, very con- 

 spicuous in the shape of striae on all male antennal joints excepting the scape 

 and funicle. 



Proximal joint of the tarsi of the caudal legs long and slender, subequal 

 to the combined lengths of the three distal joints, which are all subequal, the 

 third joint somewhat shorter than the second, the second joint somewhat the 

 longest of the three. 



(From 12 specimens, two thirds inch objective, one inch optic, Bausch and 

 Lonib.) 



Male. — Length. 0.982 mm. 



The same but more graceful, somewhat darker ; third tarsal joints with 

 some dusky ; scape concolorous with the funicle, dusky black, the pedicel alone 

 being honey yellow; first and second joints of the caudal tarsi somewhat longer 

 in relation to the others : proximal joint of the cephalic tarsi at base ventrad 

 with a few stilT bristles forming the strigil with the curved and forked cephalic 

 tibial spur. 



Abdomen (lateral aspect) hemispherical to ovate, flat ventrad. convex 

 dorsad, no longer than the thorax. 



Antennee 13-jointed, the funicle filiform and loosely jointed, all of its joints 

 •distinctly longer than wide, cylindrical and subequal, very gradually shortening 

 distad, joints 2, 3, 4, S, 6, 7 and 8 about equal and longest, the proximal joint 

 and joint 9 slightly shorter; joints 10 and 11 of the funicle each slightly 

 shorter than the one preceding, joint 11 or the club shortest of the funicle
