PHILIPPINE DIPTERA, II 39 



180. Lamprogaster placida Walk. 1849. 



Female. A specimen from Butuan, Mindanao, answers rather 

 well to the short original description of this endemic species, 

 which is the only member of this very large oriental genus as yet 

 found in the Islands; but Osten Sacken records another, un- 

 named species. The brown wing pattern consists in an irregular 

 band at base of the first basal cell, continued below over the 

 basal and anal cross veins ; a narrow oblique band, which begin- 

 ning at middle of the blackish brow r n stigma encroaches on the 

 anterior cross vein and ends a little distad of the fourth longitu- 

 dinal vein ; a narrow, complete border of the posterior cross vein 

 and a short streak at fore border just opposite to it ending a 

 little before the third longitudinal vein ; a narrow apical border 

 which begins at the above-named streak and ends at apex of the 

 fourth longitudinal vein. The abdomen is entirely shining me- 

 tallic to the base ; the legs are entirely black, even on the tarsi. 



181. Scholastes cinctus Guer. 1832. 



Numerous specimens from Los Banos and Mount Banahao. 

 Already known from the Islands and very common in the Orient ; 

 recorded also from New South Wales. 



Gorgopis cristiventris of the first century, No. 59, is now 

 placed in the genus Tropidogastrella Hendel ; there are specimens 

 also from Mount Maquiling. 



182. Zygaenula paradoxa Dol. 1858. 



Mount Banahao, Luzon, and Butuan, Mindanao. A very 

 curious fly, new for the Philippines, and previously known only 

 from Amboina. The body is almost quadrate; the present 

 specimens measure 5 to 5.5 millimeters in length and 3.6 to 4 

 millimeters in breadth. The species seems to be variable in 

 coloration; in some specimens the entire occiput is black, while 

 in others it is wholly reddish; the legs have the femora partly 

 or entirely reddish yellow, or the four posterior femora are black 

 on the basal half; the ovipositor is sometimes black, with bluish 

 base. 



183. Naupoda unifasciata sp. nov. 



A small species, closely allied to N. contracta Hendel, from 

 Formosa, and different from the typical endemic species N. 

 platessa, besides the very different coloration, in having a pair 

 of frontoorbital bristles, which are wanting in that species. 



Male. Length of body, 3 millimeters; of wing, 3.2. Head
