at end ; middle coxse with a long bristle on the middle of anterior 

 side ; apical spur of middle tibise very long, black. 



Wings spatulate, constricted to form a long and narrow basal 

 stalk; uniformly suffused with a pale yellowish tinge and with 

 the apical third inf uscated ; the internal limit of this inf uscation 

 marked by a narrow, oblique brown band, which begins at fore 

 border a little before the end of the marginal cell and, passing 

 over the hind cross vein, ends at the fifth longitudinal vein. In 

 this fuscous apical part are three distinct, oval, subhyaline spots, 

 one in the submarginal, one in the first posterior, and one in 

 the second posterior cell. Veins yellowish; the first longitudinal 

 very short, ending at end of the stalked part of the wing; sec- 

 ond very long, ending before the apex symmetrically with the 

 fourth ; while the third ends at the apex itself ; these three veins 

 are perfectly straight, placed at equal distances, and slightly 

 diverging toward the end. Discoidal cell very long, the anterior 

 cross vein placed before its middle; second basal cell a little 

 shorter than the anal cell; the basal section of the fourth in- 

 terrupted before its end; anal cell rather acute on the lower 

 angle, its terminal vein being oblique; last section of the fifth 

 longitudinal vein m.uch shorter than the perfectly straight and 

 perpendicular hind cross vein. 



Mindanao, Butuan (Baker). 



198, Stylogaster bakeri sp. nov. 



This new species is a very important addition to the oriental 

 fauna, being the first species of this genus known from the 

 Orient. It is named in honor of Professor Baker. It seems to 

 be allied to the recently described S. frontalis Krober, 1914, 

 from Belgian Congo; but it is distinct from that and from 

 any other at present known by the peculiar brush of hairs at 

 the base of the hind femora in the male. 



Male and female. — Length of body (without antennse and 

 without ovipositor), 6.5 to 7.5 millimeters; of wings, 6 to 6,5. 

 Head broader than the thorax, of almost circular outline in front 

 view; occiput flat, a little hollowed above behind the vertex, 

 black, densely gray-dusted, with few whitish hairs and a row of 

 short, bristly white hairs at some distance from the eye border. 

 Eyes reddish brown, about two and a half times higher than 

 broad in profile, with the central interior areolets much dilated; 

 frons much narrower than an eye, a little narrowed from vertex 

 to antennse, pale yellowish opaque, with a very broad shining 

 black ocellar plate, which with its obtuse fore angle is in con- 

 tact with the lunula, leaving free only a narrow line on sides at
