hyalinis venis flavis, tarsorum apicibus vix fuscescentibus ; Mas, meta- 

 thorace subcinereo. Var. Thoracis dorso cinereo, lineis tribus longi- 

 tudinalibus fuscis, scutello cinereo flavo-limbato, abdomine superne 

 fusco. Long. 1-li; alar. 3 lin. 



Yellow. Dot on the vertex, arista and tip of the abdomen Hack. 

 Thorax slightly ferruginous, indistinctly shining with white toraentum ; 

 longitudinal stripe arid sides ferruginous. Wings hyaline ; veins yel- 

 low. Tips of the tarsi very slightly brownish. Male. Metathorax 

 nearly cinereous. Var. Dorsum of the thorax cinereous, with three 

 longitudinal brown stripes ; scutellum cinereous, bordered with yellow. 

 Abdomen brown above. 



"The larva mines the leaves of the turnip and the pea; and 

 on the sea-coast it is found as late as the end of October in those 

 of the common scurvy-grass (Cochlearia officinalis), and in the 

 lady's-fingers (Anthyllis Vutneraria}. It mines sometimes in 

 companies of four or five; but in a small leaf many of these 

 desert the seat of the original colony, and commence a separate 

 establishment. The pupa is brown, darker at the tips and across 

 the lines of the segments, rather narrow, elongate-oval, finely 

 striated transversely, convex above, tess so beneath." Hardy.
