31. MICROPLITIS MONTANUS. new species. 



Allied to varicolor^ from which it differs in the blackish abdomen, 

 in the blackish or dark reddish hind coxae, in the first dorsal ab- 

 dominal plate narrowing less strongly to apex, and in the rather 

 well indicated parapsidal grooves. 



Female. — Length 2.8 mm. Head transverse, though rather full 

 behind the eyes; face, except clypeus, which is indistinctly punctate 

 and shining, vertex, and temples, minutely closely punctate and 

 opaque; antennae hardly as long as the body; mesoscutum and scutel- 

 lum shallowly confluently punctate and opaque, strongly pubescent; 

 parapsidal grooves rather well indicated; mesopleurae closely punc- 

 tate and dull anteriorly and below the deep crenate longitudinal fur- 

 row, highly polished above it ; propodeum coarsely rugoso-reticulate, 

 with a prominent median longitudinal carina, more shining than the 

 mesonotum; radius tending outward, and very little, or not at all, 

 longer than the first intercubitus ; posterior coxae short, granular at 

 base above ; spurs of posterior tibiae apparently equal in length and 

 much less than half the length of the metatarsus; abdomen a little 

 shorter than the thorax, very slender at base, broader posteriorly; 

 first dorsal abdominal plate very slender, more than twice as long as 

 its greatest breadth, distinctly a little narrower at apex than at base, 

 the sides bulging slightlj^ somewhat before the apex, finely rugulose, 

 the extreme apex elevated and highly polished; second plate broad, 

 not triangular, not distinctly separated from the third, and like the 

 following tergites, smooth and polished ; hypopygium not attaining 

 apex of the abdomen ; ovipositor not exserted. Black ; head and 

 thorax black; labrum, palpi, tegulae and wing-bases, and the four 

 anterior legs, yellow ; posterior coxae largely dark reddish to black- 

 ish; posterior femora fuscous on apical third; posterior tibiae at 

 apex, and the posterior tarsi, infuscated; wings hyaline, the veins 

 and stigma yellowish-brown, the latter with a pale spot at base; 

 abdomen black, more or less tinged with dark reddish at base ; mem-
