Head in front view roundly triangular, the malar space long 

 and the cheeks straight; vertex posteriorly and occiput impressed 

 medially, the occipital carina obliterated in the impression; third 

 joint of labial palpi very short and difficult to distinguish ; clypeus 

 very short, broadly arcuately inflexed and emarginate at apex; 

 notauli and prepectal carina absent; propodeum medially chan- 

 neled nearly to apex, without carinae; subdiscoideus at or above mid- 

 dle of discoideus; radiella terminating abruptly about the length of 

 abscissula beyond intercubitella, the other longitudinal veins in hind 

 wing virtually obliterated beyond transverse veins, nervellus very 

 weakly broken below middle; first tergite strongly narrowed before 

 spiracles, virtually without basal angles ; ovipositor subcylindrical at 

 base, slightly compressed and subsagittate at apex. Otherwise like 

 Epiurus Foerster, to which it will run in Ashmead's key.

ALOPHOSTERNUM FOLIICOLA, new species 



Female. — Length 5 mm; antennae 3.5 mm; ovipositor sheath 1.5 

 mm. Head polished, impunctate; temples convexly receding; di- 

 ameter of lateral ocellus equal to postocellar line and distinctly 

 shorter than ocellocular line, a distinct longitudinal groove betAveen 

 the ocelli; eyes parallel within, not at all emarginate opposite an- 

 tennae; face broader than long; malar space nearly as long as basal 

 width of mandible; antennae slender, 23-jointed. Thorax distinctly 

 less than twice as long as deep, slightly deeper than broad, polished 

 and virtually impunctate except on lower pleura and sternum where 

 it is sparsely punctate; propodeum impunctate; legs slender, hind 

 tarsus equal in length to tibia, its apical joint nearly as long as second. 

 Abdomen elongate fusiform, rather densely punctate and basally 

 more or less shagreened, the first tergite especially shagreened and 

 almost impunctate except at apex; first tergite a little longer than 

 broad, others very strongly transverse, the second slightly more and 

 the third slightly less than half as long as broad at their junction; 

 ovipositor sheath hardly twice as long as first tergite. 



Black, with mesopleurum, metapleurum, and propodeum usually 

 more or less piceous or ferruginous; inner orbits, broadest on frons, 

 mandibles, underside of scape, pedicel and basal joint of flagellum, 

 humeral angle of pronotum, tegulae, and wing bases whitish; clypeus 

 reddish; wings hyaline, veins brown, stigma lighter and grayish; 

 front and middle legs testaceous, coxae darker, tarsi apically and in 

 middle tarsus apices of all joints dark, middle tibia with obscure 

 annulation of brownish and white; hind coxa and femur reddish 

 testaceous, trochanter stramineous, tibia largely white with apical 

 and subbasal annuli of black, pale testaceous below; hind tarsus 

 Avhite, all joints tipped with black; abdomen black, tergites 2-5 more
