silver colour, nothing similar existing in the whole family. 

 This flies on open grassy hillsides, whilst in the forests close 

 by, a Hesperid, Cyclopides puelma', has its wings on the under- 

 side entirely of a metallic golden colour, this also being unique 

 among the Hesperidse. It seemed impossible to account for 

 such remarkable cases of coloration by any theory of protective 

 colouring. No natural frontier appeared to exist between 

 Chile and Argentina, and nearly all the mountain species 

 occurred on both sides of the political frontier, there being- 

 little difference between the alpine and the low counti^y 

 species. 



The President remarked that the Chilean Coleoptera 

 generally resembled those of the Holarctic region. Mr. 

 Roland Tbimen, F.R.S., said that in the eastern hemisphere 

 the west sides of the great continents stretching south 

 were poor in their fauna and flora. For instance, this was the 

 case in South Africa on the west, and in South Australia it 

 was even more remarkably so than in Chile. In South Africa 

 this was attributed to the cold antarctic currents that sweep 

 up to the north along the coast. 



Mr. S. L. HiNDE read a paper, illustrated by lantern slides, 

 upon " The Protective Resemblance to flowers borne by an 

 African Homopterous insect, Flata nujroc'mcUi, Walker." 

 He said that "the cluster of insects grouped to resemble a 

 flower spike," which forms the frontispiece of Professor J, W. 

 Gregory's " Great Eift Valley," had attracted some criticism, 

 and that as he was familiar with the insect figured, and with 

 its larva, in a wild state, it seemed desirable to publish the 

 evidence. In the plate the insects are collected on the vertical 

 stem, the green individuals uppermost considei'ably smaller 

 than the red beneath, like the unopened green buds towards 

 the top of a flowering spike as compaied with the expanded 

 blossoms below. The separate representations of the green and 

 red forms, however, indicate no difference in size, and experi- 

 ence confirms this conclusion, so that the impression conveyed 

 by the frontispiece plate is erioneous. After further noting 

 that the uniform deep pink colour of the exposed parts of the 

 insects figured was also incorrect, Mr. Hinde remarked that 

 he had never seen the insects grouped according to their colours,
