364 University of California PuUications. [Entomology 



linear, the costal cell extremely narrow or evanescent, the vein but 

 slightly bent. Abdomen as seen from above acutely triangular 

 in outline ; the dorsum deeply concave, the venter strongly com- 

 pressed ; the ovipositor entirely enclosed within the fifth sternite 

 which reaches to the apex ; the vibrissal plates situated at the 

 base and withdrawn within the dorsal concavity. 



Sculpture entirely alutaceous, the frontovertex much more 

 coarsely so or closely granulose, pubescence on head scanty and 

 very fine, on mesonotum more evident and arising from micro- 

 scopic punctures. Coloration non-metallic. 



MALE 

 Not differing noticeably from the female except in the struc- 

 ture of the antennae, which are somewhat longer, the scape about 

 the same, the pedicel much shorter than the first funicle joint 

 or hardly longer than thick, the funicle joints all elongate, slen- 

 der, incised at each end above except at base of first joint, each 

 clothed with rather long erect hairs arranged in three whorls, 

 the apical whorl somewhat incomplete on lower side, club solid, 

 no thicker tlian the funicle, and about one-half longer than the 

 preceding joint; the abdomen also does not become sunken in, 

 and the dorsum is more coarsely sculptured than in the female. 



Type of Genus 

 Paraleptomastix abnormis Girault 



The two other species so far known show but little deviation 

 from the above description based entirely on P. abnormis, the 

 chief differences residing in the shape of the head, and the length 

 of the middle tibial spur in comparison with the first tarsal joint 

 as brought out in the following descriptions and notes. 



The genus is most closely related to Leptomastix (Forster) 

 Mayr, which differs in having the head menisciforra, the face not 

 at all inflexed, the scrobes meeting above and separated by a 

 strongly arched ridge prominently visible in side view of head ; 

 the antennae inserted higher up or between lower corners of 

 eyes; the pedicel not over one-half as long as the first funicle 

 joint ; the funicle clothed with stiff bristle-like hairs in the female, 

 and with longer hair in the male arranged in three whorls on 

 basal three joints and in two whorls on apical three ; the club in 

 male with a fringe of short bristles on lower margin of basal 

 half; thorax more convex; wings wider and the postmarginal
