slightly at their ends towards the wing-tip ; anal vein 

 short and sinuated; halteres whitish-yellow. 



This species frequents logs in the bush during the month 

 -of November; it seems to be somewhat uncommon. 



DiAPHORUS COMMUNIS, Sp. UOV. 



Thorax dull green, frequently a little brownish ; abdo- 

 men dark brown, unicoloro'us ; legs entirely black (^) or 

 with tibiae dull brown ( 9 ), with only a few short bristles; 

 2>osterior tibise without any long bristles on the inner side. 



Length. Male, 4 mm. ; female, 3.5 mm. 



Hab. Mangalore. (Probably generally distributed.) 



Male. Eyes joined on two-thirds of the front, leaving 

 a small frontal triangle between the eyes and the antennae; 

 face rather narrow. Antennse black. Thorax dull green, 

 frequently rather brownish, and sometimes with two green 

 median strijDes ; thoracic bristles rather long ; scutellum 

 similarly coloured to the thorax, with two long and two 

 very short black marginal bristles. Abdomen shining dark 

 brown, with fairly dense black lateral pubescence, and 

 four black apical bristles. Legs black ; femora fringed 

 with black pubescence ; anterior and middle tibiae almost 

 without bristles ; posterior tibiae with a few scattered black 

 bristles. Wings with the cubital and discal veins almost 

 equidistant throughout, and curved down gently at their 

 ends towards the wing-tip ; anal vein long and nearly 

 reaching the margin ; halteres yellov^^ 



Female resembles the male very closely, but the eyes are 

 well separated, the abdomen shorter and broader, and the 

 legs generall}^ lighter. 



This species may be distinguished from D. xctosus by 

 the unicolorous abdomen, and, in the male, by the much 

 less bristly and darker legs. It may be met with commonly 

 settled on tree-trunks and on stones, and is probably 

 generally distributed. My dates range from Xovtmber 2 

 to January 26.

 short ; thorax with acrostichal bristles uniserial ; wings 

 with the radial, cubital, and discal veins parallel and 

 equidistant.
