but invai'iably mixed, that he had never found larvse and 

 imagines on the same stem or even together on the same tree 

 or bush, nor did the imagines affect vertical stems, but always 

 those actually or approximately horizontal. It does not by 

 any means follow that Professor Gregory was mistaken in his 

 impressions, but it is certain that conditions are common other 

 than those recorded by him. On comparison of material with 

 Professor Gregory's in the British Museum of Natural History, 

 Professor Poulton had come to the conclusion that both sets of 

 specimens certainly belong to the same species, viz. a form 

 slightly different from Flata nigrocincta, Walker, but evidently 

 closely allied and perhaps specifically identical with it. Con- 

 tinuing, Mr. HiNDE said that, " when disturbed the imagines 

 fly, and the larva? hop, a short distance in any direction, but 

 soon collect into groups again. The larvaj toward the end of 

 a growing branch ax'e the smallest, and this arrangement may 

 possibly reconcile Professor Gregory's account with ours." 



Professor E. B. Poultox suggested that if the larvse at the 

 top of the stem were younger, and those lower down older, 

 it was conceivable that the mature forms varied in colour 

 accordingly. Mr. Guy Marshall said that a unicolorous 

 species of Flata occuri'ed in Mashonaland, which congregates 

 on vertical stems and exudes a large amount of wax. He was 

 not able to distinguish the larval from the pupal form. Sir 

 George Hampson said the insects figured were orange when 

 first brought home, and that the pink-winged imago was 

 an error of the colourist. Mr. Colbran Wainwright re- 

 marked that in the case of British Homopteroiis insects 

 the imagines very rarely faced different ways on the stem, 

 wliile the heads of the larvfe were always in one direction.
