forms almost a right angle and is inconspicuously 

 produced. 



Squamulae whitish; haltères yellow. 



Type in my collection. 



As the characters shown in this fairly typical 

 species agree with Loew's interpretation of the genui 

 Euarcsla, I have provisionally placed it in this arti- 

 ficial genus, which was erected by Loew for several 

 sjiccies of North American Trypeta, in which the pat- 

 tern of the wings forms distinctly developed rays at 

 the apex. Hendel however, and later Bezzi have used 

 it in a somewhat wider sence. 1 have found the galls 

 in the locality mentioned above (^Yadi Hussein) as 

 well as iiï| the Wadi Hoff, and its branches east of 

 Ugret-el-Shei({, in Wadi Rishrash, Wadi Digla and 

 Wadi Garawy. If often was so common that almost 

 every plant, after close examination, would yield 

 these galls. The adult itself is quite common in the 

 above-mentioned localities, either on the host plant, 

 or on Stachys and Lavandula. My records extend from 

 February 28th to May loth 1928. The galls have been 

 described by Debski (191 7) (*).
