third of the distance between the occiput and antennae ; facets more 

 than two-thirds above dilated and reddish yellow in death, but on the 

 lower about one-thirds small and blackish ; the dividing line being 

 somewhat sharply defined and running across semicircularly so that the 

 small facets extend a long way up the back part ; two conspicuous 

 blackish spots on the yellow part of which the large one is long and 

 transverse as in the preceding species, but much nearer to the hind 

 margin of the eyes, the small one is usually triangular, being pointed 

 below and reaching to the blackish part, but it is sometimes very small 

 and inconspicuous and consequently not extending to the blackish part. 

 Antennae similar to those in the female, but distinguished by much 

 numerous and longer erect pubescence on the basal joint. 



Thorax much shorter and somewhat rounded in shape, the 

 pubescence on the disc very short and somewhat depressed, but inter- 

 mixed with a few very fine rather very long almost erect hairs ; 

 scutellum somewhat flatty, triangular, being long sparse hairs round 

 the margins ; pleurae like the female, but somewhat densely haired. 



Wings comparatively large, the cross-band with not angulated 

 inner margin, and almost always inwardly curved outer margin ; the 

 anal cell very rarely hardly closed. 



Legs much darker, brownish, but the two anterior femora, the 

 two posterior tarsi, the basal part of the fore and hind femora, and the 

 both ends of the middle femora, yellowish ; the pubescence on the 

 legs usually longer than that in the female, and especially on the 

 femora numerous. 



Abdomen usually shorter and somewhat paler, the pubescence 

 usually longer and especially at the sidos. 



Length : about 9 mm. 



This species shows very little variation in a number ot specimens 

 (14 males and 14 females) from Formosa, and two males from Hainan 

 Island and Ceylon, from the former the above description has been 

 made, but in one female from Horisha (10th of May, 1 9 1 3 ) the black
