XII. D, 3 Bezzi: Studies in Philippine Diptera, II 139 



Male. — Frons slightly but distinctly narrower; third antennal 

 joint proportionally shorter and broader; antennse considerably 

 shorter than the face; mesonotum without anterior band of 

 white dust; pleurae destitute of shining white pollen. Tibiae of 

 male with no distinct tubercle above end. 



In the wing pattern there are the two following considerable 

 differences : a, the yellow patch at fore border is continuous, not 

 at all interrupted by dark and hyaline spots; b, the brown 

 pattern around the anal cell is much broader, extending as a 

 broad band along the anal vein and reaching the hind border. 



The sexual differences in wing pattern described by Hendel 

 from Javan specimens are quite absent; thus the middle of the 

 second posterior cell is wholly hyaline, without any oblique dark 

 band ; the brown border of the fifth longitudinal vein has below 

 toward its middle no dentiform projection." The discoidal cell 

 is completely infuscate only in its distal eighth part.

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 brown 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 Baiios 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. 



" But in the male specimens of typical L. decora from Singapore in my 

 collection these sexual characters are also absent.
