PHILIPPINE DIPTERA, II 33 



whitish pubescence and rather long whitish hairs on the sides; 

 hypopygium black; venter pale yellowish. Legs with the coxae 

 and the tarsi pale yellowish, but the hind femora and the hind 

 tibiae black, the last with yellowish ends; front and middle 

 femora with a subterminal brown streak above; pubescence 

 short, whitish. 



Wings grayish hyaline, iridescent, with yellowish veins and 

 colorless stigma. End of the marginal cell filled by a large deep 

 black spot, which is at least in part callously chitinized. The 

 two chitinous calli deep black, rounded, and placed near the 

 hind border, the smaller before upper end of second posterior 

 cell, the larger at lower inner end of same cell, just at the angle 

 between posterior cross vein and last section of fifth vein. On 

 the underside of wing a strong, straight, chitinous spine, placed 

 on middle of second posteror cell, below the angle of the pos- 

 terior cross vein with the fourth longitudnal vein, and directed 

 inward. This spine is black, but its broadened basal part is 

 grayish hyaline, like the wing membrane ; its length is about 0.5 

 millimeter. 



LUZON, Laguna, Mount Maquiling (Baker} , one male. 



171. Antineura sericata O. S. 1882. 



Cagayan, Mindanao. A beautiful endemic species of great 

 size. The ortalid genus Antineura also may be considered as 

 endemic, as the other species are generically different and must 

 be placed in Adantineura Hendel. 



172. Xenaspis polistes O. S. 1882. 



Malinao, Tayabas, Luzon, and Butuan, Mindanao. Another 

 endemic and very characteristic species of great size, very much 

 like a vespid. 



173. Xenaspis extranea sp. nov. 



This species is not unlike X. polistes Osten Sacken in general 

 aspect and coloration, but differs in having the apical cross vein 

 of the second basal cell less oblique. This fact is in relation 

 with the other that the wings in the present species are not 

 susceptible of being folded along the middle line as they are in 

 polistes, which gives the latter its wasplike appearance. The 

 present new species agrees with polistes also in lacking praescu- 

 tellar bristles, but it has a well-developed mesopleural bristle. 



Female. Length of body (without ovipositor) , 10 to 12 milli- 

 meters; of wing, 8 to 10; of ovipositor, 1.5 to 2. Head entirely 

 reddish yellow, rather shining on the occiput, the latter with 

 two small black parallel streaks on the middle extending from
