endemic, as the other species are generically different and must 

 be placed in Adantineura Hendel.

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 

 the neck to the sides of the vertex; frons opaque, darker in the 

 middle, with short yellowish pubescence; ocellar dot black; the 

 two pairs of vertical bristles, the only macrochsetse of the head, 

 black; face pale yellowish in the middle, reddish on cheeks and 

 on the sides below ; antennal grooves with a long black streak at 

 lower end. Antennae a little longer than half the face, entirely 

 pale yellow. Third joint somewhat attenuated at end, with a 

 long, thin basal arista, which is shortly pilose above on the 

 basal third. Palpi reddish, with darker base and yellow hairs; 

 proboscis thickened and dirty yellowish brown. 



Mesonotum entirely reddish yellow, darker on dorsum and 

 with short yellowish pubescence; humeral calli, a longitudinal 

 stripe above the notopleural line, a broad and oblique meso- 

 pleural stripe ending at the sternopleural suture, and two broad, 

 contiguous stripes rounded by propleural spots yellow. Scutel- 

 lum entirely yellow, with the base narrowly reddish brown; 

 mesophragma shining reddish. Macrochaetae black — two noto- 

 pleurals, three supra-alars, one mesopleural, and one scutellar 

 apical ; sometimes exterior scapular bristles on one side only, the 

 humeral always wanting ; scutellum sometimes with two or three 

 more bristles near the end; sometimes also a weak praescutellar 

 bristle on one side only. Halteres yellowish. Abdomen longer 

 than thorax, distinctly narrowed at base, but not properly 

 stalked ; it is entirely reddish yellow, with short yellowish pubes-
