Falkland Islands Diptera. 393 



suturai) just before the V-shaped cross furrow at the side, two noto- 

 pleurals on the much-abbreviated notopleura, and one supra-alar; 

 between all are the small bristles. The scutellum is slightly rounded 

 with a shallow furrow in front, the terminal bristles are large, upright 

 and crossed at tip, each side is a smaller rather depressed bristle. 

 The pleura is silvery grey, more orange below; it is covered with 

 small scattered bristles and has a large mesopleural bristle, and 

 there is a large sternopleural one. 



The wings are reduced to small pointed orange flaps with short 

 stout bristles, the thoracic squama is present, though minute. 

 The halteres are reduced to stout orange rods. 



The legs are bright orange, stout, and profusely covered with 

 bristles, all the femora and coxae are rather pollinated with silver ; 

 the only stout bristles are inferior crowns to mid and hind tibiae, 

 and a pair beneath each tarsal joint. The 1st tarsal joints of all 

 the feet are rather shorter than the rest of the feet, and have 

 inferiorly a dense pile of stout orange bristles. The last joints are 

 rather flattened and have long dorsal hairs, very stout curved claws, 

 delicately feathered pads, and a long empodium of several fine 

 hairs. 



Abdomen : — long — oval with rounded end : in colour it is silvery- 

 grey like the rest of the insect, but has rather ill-defined brown 

 marks as follows : smallish side spots on 2 and 3, a large median 

 oval spot on 1, a central V on 2 extended almost across segment, 

 a similar rather larger and more slender V on 3. The segments 

 1, 2, 3 are about equal, but 4 is about 1J times as long. The 

 whole surface is covered with bristles which are reddish in certain 

 lights, the marginals are black and longer. In side view the end is 

 cut off obliquely, the 5th segment has a very large terminal pit 

 which hides the complex genitalia. 

 Length about 2\ mm. 

 Wings about '3 mm. 



$?. Very like the male except that the abdomen is longer and the 

 segments are all equal, the brown marks are reduced to very indis- 

 tinct central spots : the lower part of last abdominal segment 

 carries a pair of very stout curved claws.

Synhoplos ne^lectus, n. sp. 



This species is somewhat larger than the last, and is 

 very much more bristly and robust in appearance.
