72 ME. W. F. KIEBT ON" THE 



Catalogue of the described Hemiptera Heteroptera and Ho- 

 moptera of Ceylon, based on the Collection formed (chiefly 

 at Pundaloya) by Mr, E. Ernest Grreen. By W. E. Kirbt,

 Museum (Natural History), S. Kensington, S.W.

 (Plates IV.-VI.) 

 DuEiNG the residence of Mr. E. Ernest Green in Ceylon, he 

 formed a large collection of insects of all Orders, part of which, 

 including a fine series of Hemiptera Heteroptera and Homo- 

 ptera, he has liberally presented to the British Museum. Most 

 of these were obtained at Pundaloya, in the hill-country ; but 

 some, more especially among the aquatic species, are from 

 Nitagala, in the north central part of the island, and a few are from 

 Nawalapitya, Kandy, Colombo, and other places, "Where no 

 locality is mentioned in the following pages, it may always be 

 inferred that the insect is from Pundaloya, unless the habitat 

 is indicated as doubtful. 



Mr. Green's collection proved to contain so large a proportion 

 of the species already known from the island, that I thought it 

 would he rendering a real service to science to publish a complete 

 list, adding descriptions of most of the new ones. Such lists of 

 species from a restricted locality are of great value, as they form 

 a more satisfactory hasis for future work than in the case of 

 more extensive Eaunas. 



Nearly all the larger species already known from Ceylon are 

 represented in Mr. Green's collection ; but although he obtained 

 a fair number of the smaller species likewise, yet, as these must be 

 extremely numerous in Ceylon, and the few which have been de- 

 scribed were mostly obtained from localities diflierent from those 

 where Mr. Green collected, it is perhaps not surprising that his 

 collection not only contained a much larger number of new species 

 among the smaller species than among the larger (which might 

 reasonably have been expected in any case), but that compara- 

 tively few of the smaller species which have already been de- 

 scribed could be found among his specimens. However, I was 

 glad to find representatives of the interesting genera Macropes 

 and Ossa of Motschulsky. 



I have not ventured to describe the whole of the smaller species 

 obtained by Mr. Green. In some cases it would be desirable 

 to compare them with other species which have already been
