This species varies much as to colour. According 

 to Mr. Edwards, two distinct species may be separated 

 from some of the varieties hitherto considered to be 

 L. pellucida. 



The Brachypterous male and female show many 

 shades of colour from pale brownish yellow to deep 

 black. Scutellum more than twice longer than the 

 pronotum. Elytra half the length of the abdomen ; 

 nervures set with fine brown bulbous granules. 



Macropterous male. Head, body and abdomen all 

 black, except that often below the scutellum an orange 

 patch appears. Keels of the head and the scutellum 

 grey. Second joint of the antennae stout, and tufted 

 with bristles. Frons black, with three unforked grey 

 carina. Pygofer black, with a square, deep, semi- 

 circular notch in the midst, from within which the anal 

 process protrudes. Styles with obtuse, recurved, and 

 truncated ends, spread horizontally from their bases. 

 Elytra yellowish hyaline, one and a half times the 

 length of the abdomen ; nervures brown, with black 

 setigerous dots. A strong beaded band runs round 

 the apical borders. Wings transparent and colourless. 

 Legs ochreous-yellow. (Through an error, the position 

 of these styles — see fig. 7 — is drawn much too 

 vertically.)
