15. MICROPLITIS LONGICAUDUS, new species. 



Nearest croceipes, with which it agrees in the smooth, almost im- 

 punctate head and mesoscutum, in the short and stout posterior 

 femora, and the slightly bulging posterior orbits; it differs from 

 that species in its hyaline wings and longer ovipositor. 



Female. — Length 3.8 mm. Head with the face distinctly though 

 very shallowly punctate, rather shining, the clypeus impunctate and 

 polished; vertex, temples, and cheeks practically impunctate, sub- 

 polished; the temples bulging slightly beyond the line of the eyes; 

 antennae much shorter than the body; mesoscutmn virtually im- 

 punctate, subpolished, pubescent; scutellum with indistinct setiger- 

 ous punctures, shining; mesopleurae with a sharply marked, curved 

 longitudinal crenulate furrow, mostly polished, minutely indistinctly 

 punctate below the furrow and anteriorly; propodeum coarsely ru- 

 gose, with a prominent median longitudinal carina ; fore wing with 

 the radius directed outward, very slightly longer than the trans- 

 verse cubitus ; stigma longer than the metacarpus ; posterior femora 

 very short and stout, less than two and one-half times as long as 

 their greatest breadth ; posterior tibial spurs short, subequal, decid- 

 edly shorter than half the metatarsus ; last segment of posterior tarsi 

 twice as long as the preceding segment; abdomen as long as the 

 thorax, rather stout; the first dorsal plate parallel-sided, apex and 

 base of equal breadth, more than twice as long as broad, and mostly 

 smooth and polished; the membranous margins rather broad along 

 apical third of first plate; remainder of the abdomen polished; 

 hypopygium large, prominent, very slightly surpassing the apex of 

 the last dorsal segment; ovipositor sheaths truncate at apex, pro- 

 jecting nearly half the length of the abdomen. Black ; clypeus red- 

 dish; palpi pale; antennae wholly black; tegulae and wing-bases 

 black; wings hyaline, with an indistinct infumated patch just below 

 stigma; veins yellowdsh-brown ; stigma dark brown, with a large 

 pale spot at base ; legs, except the black coxae and basal segment of 

 trochanters, dark testaceous ; abdomen black, except the membranous 

 margins along the first dorsal plate, which are pale; ovipositor 

 sheaths black.
