The two following species belong to the genus Scaptomyza of 

 Hardy, who characterizes it thus : " Body elongate, rather nar- 

 row. Head subtriangulate, moderately transverse behind ; sides 

 obliquely sloped, so as to straiten it anteriorly, which contraction 

 slightly affects the fore part of the frontal band ; front sparingly 

 bristly ; face somewhat slanted, keel moderate ; bristles of the 

 peristoma rather scant and short ; eyes suboval, finely pubescent ; 

 proboscis dilated at the tip. Palpi rather narrow, ovate, or sub- 

 elliptical. Antennae with the third joint parallelogrammic, its 

 tip rounded (lingulate). Arista with a few long hairs, mostly on 

 the upper side. Thorax somewhat longer than broad, subparal- 

 lelogrammic, faintly glossy, the colouring striped. Wings nearly 

 as in DrosopJiila, but not so broad. Abdomen subconical r rather 

 long and narrow ; its tip in the female slightly compressed, ob- 

 lique, with shining serrated plates beneath. Larva living as a 

 miner on the parenchyma of leaves." Hardy, Proceedings of the 

 Berwickshire Naturalists' Club, 361, 1849.

Hoary, slender. Head testaceous in front and beneath. Antennas 

 testaceous. Thorax with three brown stripes. Wings hardly tinged 

 with grey, rather narrow ; veins tawny ; discal transverse vein upright, 

 parted by full thrice its length from the praBbrachial transverse, and by 

 much more than its length from the border. Halteres and legs testa- 

 ceous. Abdomen piceous ; of the female fusiform. 



" The larva is subcutaneous in the leaves of the common chick- 

 weed (Stellaria media], of the corn-cockle (Lychnis GUhago], of 

 Chenopodium album, and of Viscaria oculata and Silene Armeria 

 in gardens. Its operations are marked by a large shapeless blotch, 

 with smaller winding galleries conducting to it." Hardy.
