338 BRUES. 



median cell much longer than the median; second discoidal large, 

 oblong; closed by a weak vein at the tip. Legs moderately thickened. 

 While the type species is very much like Pristocera it is remarkable 

 in having the female winged and like the male, not entirely apterous 

 and so different from the male as in the recent genus. On this account 

 it appears to be a stem form close to those from which the recent 

 Pristocera has developed with its greatly degenerate female. Recently 

 Kieffer (Bull. Soc. Hist. Nat. Metz XII, p. 98 (1905)) has described a 

 genus Propristocera from the Indian region which is known only in the 

 male sex. It is of course possible that this genus may be found to have 

 winged females and approach the present one although this appears 

 unlikely. If such be the case the present one may not be distinct 

 although it differs by its pubescent eyes and quite distinct second 

 discoidal cell. 



Protopristocera sucini sp. now 



9 . Length 4.5-5.25 mm. Apparently uniformly dark-colored, 

 with hyaline wings. Head from tip of mandibles about twice as long 

 as high. Eyes close to the mandibles, but not contiguous; separated 

 from the hind margin of the head by a little more than their own 

 length. Head above finely punctulate and clothed with a fine, close, 

 pubescence; on the underside with very sparse, delicate, setigerous 

 punctures. Antennae inserted close together on a frontal tubercle. 

 Antennal scape as long as the following three joints, curved, and 

 slightly thickened apically; pedicel and following joints of nearly 

 equal length, thickening to the second flagellar, then becoming more 

 slender to the tip; penultimate and last longer and shorter than the 

 others, respectively; tip of antenna? reaching about to the tip of the 

 propodeum. Pro- and mesonotum finely punctulate and thinly 

 hairy. Parapsidal furrows very delicate, the lateral pair more deeply 

 cut anteriorly. Mesopleura smooth, margined by a foveate line; 

 with a foveate depression medially, above which it is divided by a 

 carina nearly perpendicular to its hind margin. Upper surface of 

 propodeum margined laterally and at the tip, with a median carina 

 which extends to the tip of the posterior slope; with two other less 

 distinct carina? above on each side of the median one. Each posterior 

 angle with a small areola. Pleurae and posterior slope irregularly 

 wrinkled. Abdomen conic-ovate. Legs, except anterior femora, 

 only slightly thickened; four posterior tibiae each with two spurs; 

 tarsal claws slender, apparently entire. Wings hyaline, marginal cell
