ART. 2. ICHNEUMON-FLY GENUS METEORUS MUESEBECK. 25 



above; remainder of abdomen smooth and polished; ovipositor 

 sheaths about 6 mm. in length, distinctly longer than the entire 

 body. Black; head mostly ferruginous; pro thorax ferruginous, 

 brownish above on the sides; rest of thorax black; tegulae testaceous; 

 wings hyaline, stigma brown, pale at base; legs ferruginous, the 

 hind femora at apex, apex of hind tibiae and the hind tarsi more or 

 less infuscated; first abdominal tergite black; second and third 

 tergites ferruginous; beyond, brownish black. 



Male. — Thorax not so black as in female, rather brownish black; 

 first abdominal tergite reddish black; malar space longer than basal 

 width of mandibles; inner spur of posterior tibiae nearly a third the 

 length of metatarsus; otherwise agrees with female. 



Type.—Csit. No. 24962, U.S.N.M. 



Type locality. — Grand Ledge, Michigan. 



Host. — Probably Orchesia castanea Melsheimer. 



Described from one male and one female which were included in 

 Ashmead's type series of orchesiae. The female had no red label, 

 but the word "Type" was written in one corner of the name label, 

 in Ashmead's hand; the male bore a red label with the type cata- 

 logue number of orchesiae. 



17. METEORUS HICORIAE, new species. 



Closely resembles Tiumilis and terehratus, but distinguished as 

 noted in the key. It also resembles tibialis, agreeing with this 

 species in the stout first abdominal segment; it differs, however, in 

 the shorter ovipositor and the paler legs. 



Female. — Length 4 mm. Head transverse, but rather full behind 

 the eyes; face broad, much broader at base of clypeus than long, 

 minutely sculptured; clypeus punctate; malar space less than half as 

 long as basal width of mandibles; antennae much shorter than body, 

 24-segmented ; ocelli very small, the ocell-ocular line at least two and 

 one-half times the greatest diameter of an ocellus; vertex and temples 

 polished; mesoscutum indistinctly punctate, shining; the mesonotal 

 lobes prominent, the parapsidal grooves strongly impressed; propo- 

 deum weakly roughened, with a median, two sublateral, and two 

 transverse carinae marking off four areas on the dorsal face; pro- 

 pleura almost entirely smooth, strongly shining; mesopleura smooth 

 and polished, somewhat punctate in the basal upper angle, and with 

 a finely crenulate longitudinal furrow; metapleura mostly smooth 

 and shining; wings with stigma large, triangular; first abscissa of 

 radius shorter than the second, the second less than half the length 

 of the first in tercubitus; radial cell long, nearly attaining apex of 

 wing; third abscissa of radius as long as last abscissa of cubitus; 

 recurrent vein not quite interstitial with first intercubitus, entering 

 apical angle of first cubital cell; nervulus a little postf ureal; posterio'r
