ART. 3 SOME NEW CHALCID-FLIES TIMBERLAKE 21 



scutellum a little longer than wide, rather acutely pointed at apex, 

 the disk somewhat depressed medially, but the sides strongly ele- 

 vated, at first rounded, then abruptly declivous; propodeum very 

 short, even at the sides, and sloping strongly backward, mesopleura 

 considerably narrowed anteriorly and distinctly emarginated on the 

 dorsal margin opposite the root of the fore wing. 



Abdomen about as long as the thorax, broadly oval and depressed, 

 or sometimes shrinking so that the dorsal surface becomes more or 

 less sunken in; cereal plates situated beyond the middle of the 

 lateral margins; ovipositor sheaths barely projecting beyond the 

 apex, the spicula free and inserted near base of abdomen. 



Legs normal in length and structure; middle tarsi stouter than 

 the hind pair, tapering, the basal joint not quite so long as the next 

 four joints combined; spur of middle tibiae somewhat shorter than 

 the first joint of the middle tarsi. "Wings reaching far beyond apex 

 of the abdomen, moderately broad and well rounded at apex; disk 

 including basal area with very short and dense setae, the marginal 

 fringe short and dense; speculum very narrow but distinct, extend- 

 ing obliquely across the disk; apex of venation reaching nearly to 

 the middle of the costal margin, the submarginal vein almost 

 straight and not enlarged distad, marginal vein punctiform, the 

 postmarginal nearly but not quite entirely obsolete, stigmal vein 

 moderately long, at an angle of about 45° with the costal margin, 

 slender at base and triangularly enlarged toward apex. 



Face, cheeks, collar of pronotum, and the mesonotum uniformly 

 and very finely subrugulosely reticulato-punctate and rather dull; 

 frontovertex with somewhat coarser, more thimblelike, reticulate 

 punctures ; propleura very finely and closely longitudinally lineolate ; 

 mesopleura smoothish, but with dense microscopic reticulato-lineo- 

 lations; metanotum and propodeum smooth; abdomen finely reticu- 

 late, not at all rugulose but considerably smoother and more lustrous 

 than the thorax. 



Pubescence of head and thorax very fine, short, appressed, and 

 whitish but hardly conspicuous, mostly confined on head to the 

 cheeks and lower part of the face, sparse on the mesoscutum and 

 scutellum, the latter without larger, more erect setae at apex; eyes 

 bare; abdomen with rather sparse, short, fine pubescence on the 

 sides and somewhat longer setae at the apex and on the ovipositor 

 sheaths. 



Coloration nonmetallic, rather dull black or brownish black, with 

 cream-colored or pale buff markings on the head and part of the 

 thorax. 



Male. — ^Very similar to the female, but the head is a little shorter 

 and wider, the eyes smaller, the cheeks proportionately longer, the 

 frontovertex wider or no longer than broad, the ocelli arranged in
