sometimes partly broken tip into linear dots. Wings entirely hyaline, 

 venation pale to the nodus and arculus. Abdomen above with blackish 

 median and lateral lines, the lateral varying much in breadth and some- 

 times interrupted at the distal end o£ the segments up to the 8th ; 

 segments 9, 10 black above. None of the females shows any trace of 

 dark patches on the wings ; in B. leucosticta females exist with dark

A long series of both sexes from Amara April 10th to April 28th, 

 May 4th, June 29th, August 26th, and September 6th to 27th {Evans) ; 

 April 9th, 10th, and 28th, Amara, and May 17tb, 1918, Qurnah 

 {Buxton). 



Immature specimens to the end of April, but even as early as the 10th 

 of that month, some of the males had begun to take on their dai"k 

 coloration. Fully mature specimens in May and June. In August 

 and September immature examples again appeared. 



There would thus appear to be two broods, or two separate periods 

 of emergence, in the year, the examples taken in the second being of 

 smaller size than in the earlier.

 especially about open cultivated ground, where they rest on grass stems,
