1. MIROCHALCIS ATRICORPUS new species. Genotype. 



Fiiniilc : — Length, 5.85 nun. 



Black, the wings hyaline, the venation black, the tarsi brown. Postmarginal vein twice 

 the length of the stigmal or nearly but less than half the length of the marginal. Scutellum 

 rather deeply emarginated at apex. Head, thorax and abdomen clothed with a fine dow'n, the 

 head and thorax densely punctate, the propodeum rugose but with a more or less distinct median 

 channel with carinated sides and including cross-carinaj; spiracle very long, slotlike, curved, 

 the ends wider. Along cephalic margin of scutum, midway between meson and lateral margin, 

 an obscure impunctate area densely scaly. Third segment of abdomen with several rows of 

 pin-punctures eephalad, then very finely punctulate, the last segment (retracted) rather 

 coarsel}' punctate (but not by far like the umbilicate punctures of the thorax). Segment 2 

 subglabrous. exceedingly finely punctulate. The pin-punctures on segment 3 are interrupted 

 at the meson and spread laterad. Segment 2 occujiying somwhat over half of the surface. 

 Scape normal, the pedicel wider than long; funicle 1 distinctly longer than wide, 2 barely 

 so, the distal funicle joint a little wider than long. Hind femur with ten moderate-sized teeth, 

 more or less equal or gradating.
