ART. 2. ICHNEUMON-FLY GENUS METEORUS MUESEBECK. 19 



base aud one at apex of truncation, all very weak; petiole ruguloso-striate, without 

 fossae dorsally, or if present they are very indistinct; rest of abdomen smooth and pol- 

 ished; ovipositor nearly as long as thorax and abdomen together and only a little 

 swollen at base; wings with stigma triangular, radius originating in the middle, first 

 abscissa of radius not more than one-third the length of the second abscissa, the 

 latter shorter than second transverse cubitus; nervulus very slightly postfurcal. 

 Head and thorax dark succineous, abdomen blackish above. 



This species seems to be very similar to alaskensis Ashmead, and 

 may be identical with it, in spite of Provancher's mention of infumated 

 wings. In the description of species belonging to other groups :his 

 worker has often referred to faintly subhyaline wings as "slightly 

 infumated ' ' ; should that be the case here the species will run to alas- 

 Icensis in the foregoing key. 



11. METEORUS ANGUSTIPENNIS, new species. 



A very slender species, with unusually narrow, somewhat infu- 

 mated, wings; it is easily distinguished horn, fumipennis by the very 

 long lower abscissa of basella, and by the finely punctate condition of 

 the vertex and mesonotal lobes; from politiis it is at once separated 

 by the practically sessile first discoidal cell. 



Female. — Length 3.2 mm. Head transverse, very slightly broader 

 than thorax; eyes enormous, strongly convergent; face unusually 

 narrow, its w^dth at base of clypeus much less than its length from 

 antennae to clypeus, very minutely scailptured; malar space so short 

 as to be almost wanting; antennae missing beyond pedicel; ocell- 

 ocular line two and one-half times as long as gi'eatest diameter of an 

 ocellus; vertex, temples, and cheeks shining, distinctly very finely 

 punctate; thorax very slender; mesonotal lobes prominent, minutely 

 but distinctly sculptured, especially the middle lobe; lateral lobes 

 meeting posteriorly; disk of scutellum very small, somewhat elevated, 

 polished; propodeum rugoso-reticulate, with a suggestion of two 

 large median areas on dorsal face; propleura, mesoplem-a except 

 posteriorly, and the metapleura, coarsely rugulose; wings narrow; 

 nervulus in type very slightly antefurcal; recurrent vein entering 

 first cubital cell; first abscissa of radius as long as, or longer than, the 

 second; last abscissa of radius attaining wing distinctly before apex; 

 lower abscissa of basella at least one and one-half times as long as 

 nervellus and decidedly longer than upper abscissa of basella; pos- 

 terior coxae small, about as long as their trochanters, slightly rough- 

 ened on outer face; inner spur of posterior tibiae about one-fourth as 

 long as the metatarsus; abdomen very slender; the first tergite finely 

 ruguloso-striate, especially on the postpetiole, and provided with 

 two distinct dorsal fossae on the petiole; remainder of abdomen 

 smooth and shining; ovipositor sheaths about as long as the abdo- 

 men. Black; face, clypeus and mandibles brown; wings distinctly 

 infumated; stigma brown; paler at base; legs ferrugino-testaceous ;
