Habrocytus brachygaster sp. n. 



(Text-fig. 416) 



$. Body dark green to dark blue-green ; occipital surface of head, pronotal neck, meso- 

 pleuron partly, and sometimes disc of gaster, bluish black. Antennal scape more or less test- 

 aceous at base, otherwise blackish with a metallic tinge, like the pedicellus ; flagellum fuscous, 

 not distinctly paler beneath excepting the sensilla. Coxae, and femora except their tips, black 

 with a metallic tinge ; trochanters mainly to entirely dark ; legs otherwise testaceous with at 

 least the mid and hind tibiae more or less broadly infuscate medially ; tarsi fuscous at tips, fore 

 tarsi mainly fuscous. Tegulae blackish with a metallic tinge. Wings hyaline ; venation pale 

 yellowish to fulvous, the parastigma and stigma sometimes slightly darker. Length 2 to 2-2 mm. 



Head only slightly broader than the mesoscutum ; in dorsal view 2-25 to 2-3 times as broad 

 as long, with temples hardly more than one quarter as long as eyes and rounded off ; POL i"65 

 to i-8 OOL. Head in front view suboval with genae moderately buccate. Eyes separated 

 by about 1 -5 times their length. Malar space slightly less than, or nearly, half the length of an 

 eye. Structure of clypeus, and sculpture of head, as in albipennis ; frons rather more coarsely 

 reticulate than rest of head. Antennal scape more than three quarters as long as an eye, 

 reaching level with the lower edge or the middle of the median ocellus ; combined length of 

 pedicellus and flagellum much less than breadth of head ; pedicellus in profile about 1 -6 times 

 as long as broad, as long as or distinctly longer than the first funicular segment ; flagellum 

 only moderately clavate, proximally distinctly stouter than the pedicellus ; first funicular 

 segment quadrate or subquadrate, following segments subquadrate, the sixth, sometimes also 

 the fifth, very slightly transverse ; clava about twice as long as broad, as long as two and a 

 half or three of the preceding funicular segments ; sensilla fairly numerous, in one row on all the 

 funicular segments. 



Thorax barely 1-5 times as long as broad. Pronotal collar slightly less wide than the meso- 

 scutum, about as long medially as at the sides, one fifth or slightly more than one fifth as long 

 as the mesoscutum, coarsely reticulate in the middle, more finely so at the sides ; its front edge 

 abrupt, sometimes weakly and irregularly margined in the middle. Mesoscutum 1 -6 to 1-65 

 times as broad as long, finely reticulate at the sides, more coarsely so discally. Scutellum hardly 

 longer than broad, finely reticulate, the frenum slightly more coarsely than the rest. Propodeum, 

 medially, slightly more than one third as long as the scutellum ; median area 2 to 2-2 times as 

 broad as long, similar to that of scandiae sp.n. but rather more shiny and more irregularly 

 sculptured, the plicae rather more distinct anteriorly, the callus more shiny, alutaceous. Post- 

 spiracular sclerite, meso- and metapleuron much as in scandiae. Fore wing much like that of 

 scandiae, but having the row of hairs on the lower surface of the costal cell usually complete, 

 occasionally narrowly broken, marginal vein only 1-15 to 1 -35 times as long as the stigmal vein ; 

 postmarginal vein usually as long as or slightly longer than the marginal, rarely very slightly 

 shorter. 



Gaster short-ovate, as long as or slightly longer than the thorax, about as broad as the thorax 

 and not compressed, 1 -4 to 1 -9 times as long as broad, acute though not acuminate apically ; 

 basal tergite occupying about one third of the total length ; last tergite only about half as long 

 as its basal breadth ; ovipositor sheaths slightly exserted ; hypopygium extending about half 

 way along the gaster. 



cj. Not definitely associated. Some males taken in company with the above females may 

 be conspecific with them ; they are much like those of albipennis (Walker) but smaller (Text- 

 fig. 416).
