from front deeper than the width, both the frontal and facial margins 

 straight, and the former much shorter than the latter and about as 

 long as the outer-lower margin which is very slightly curved below, 

 the outer-upper margin longest and more than twice of the frontal 

 margin and evenly rounded, the frontal angle about 1 45°, and the 

 lower angle about 95 ° with rounded angle ; facets on wholly the upper 

 two-thirds very much larger (about seven times) than those on the 

 lower part, and the large facets extend upwards to the vertex and 

 downwards to and rather beyond the junction of the eyes, while the 

 small facets extend in a narrow zone up along the back margin ; the divid- 

 ing line across the eyes is rather undulating about the middle of the 

 dark portion of the frontal triangle, and it runs somewhat horizontally 

 for a short distance behind and then going slightly below obliquely 

 and after the middle of the eye gradually upwards, and the line at least 

 advances up to the vertex, the back zone keeping nearly equal in 

 width throughout but very slightly contracting towards the vertex ; in 

 death reddish brown with the small facets black with a coppery shim- 

 mer, but about the middle of the large facets more or less blackish as 

 if it has a broad transverse band, or sometimes very conspicuously 

 triangularity blackish. 



Thorax darker or seldom greyer than the female, with less con- 

 spicuous stripes ; the erect black pubescence on the disc longer and 

 much numerous and with less short yellowish hairs intermixed ; the 

 tufts on the bases of the wings and on the postalar calli nearly as 

 same as those in the female ; scutellum somewhat larger than that in 

 the female, and similarily pubescent ; pubescence on the pleurae much 

 denser and longer, and on the mesopleurae there are much more con- 

 spicuous blackish hairs intermixed. 



Wings, squamae, and halteres almost as in the female, the first 

 shorter than the thorax and abdomen together and with rather narrowed 

 apex and longer discal cell. 



Legs almost as in the female, but with the less conspicuous
