superficial than in the type, from which it differs, like the race 

 striatum, in the much more angular junction of the pro- and meso- 

 notum. The 1st node is also narrower above, and the base of the 1st 

 abdominal segment more distinctly sti'iate. The frontal carinae are 

 more prominent than in the type.

^ . 4"6 mm. Head, antennae, and nodes yellowish-red, thorax 

 reddish-yellow, abdomen and legs bright ochreous yellow, the abdomen 

 sometimes more or less brownish-yellow. Differs from the type by 

 the stronger sculpture. The frontal carinae are decidedly stronger, 

 forming prominent ridges bordering the demiscrobes. The junction 

 of the pro- and mesonotum, seen in profile, is much more angular, 

 even more so than in var. Phasias. The pro-mesonotal suture is 

 indicated by a dark transverse ridge. First node of the petiole more 

 abruptly truncate in front, the anterior face as long as the posterior. 

 The sculpture of the 2nd node as strong as that of the 1st (distinctly 

 weaker in the type and var. Phasias). The basal third of the 1st 

 abdominal segment finely and longitudinally striate, and rather dull. 



9 . 5 mm. Mesonotum and scutellum longitudinally reticulate- 

 rugose ; the posterior two-thirds of the mesonotum flat. Pronotum 

 not much exposed above, the shoulders much less angular than in 

 the ^ • Dorsum of epinotum moderately oblique, as long as it is wide 

 between the spines. Wings hyaline, nervures and stigma pale yellow. 

 Otherwise like the £ . 



£ . 4 - 2 mm. Head yellowish-brown, thorax and abdomen brownish- 

 yellow, the parapsidal sutures of the mesonotum and the margins 

 of the scutellum darker, legs, antennae, and mandibles ochreous. 

 Pilosity and pubescence much sparser than in the $ . Head and 

 nodes subopaque, thorax and abdomen nitidulous. Head finely 

 reticulate, with a few fine longitudinal striae' on the vertex in front 

 of the ocelli, and also some oblique striae behind them ; between the 

 eyes and antennal sockets transversely striate. Thorax and nodes 

 longitudinally striate, very finely and fairly closely so on the meso- 

 notum and scutellum and 2nd node, more coarsely so on the epinotum 

 and 1st node ; the latter are also partly reticulate, and the epinotum 

 is also closely and shallowly punctate between the striae. Head 

 narrower behind the eyes than in front, the posterior margin straight
