the wide field the Psyllidce offered for the discovery of new species and 

 observation of economy, the variety in the latter being very great, some 

 species rolling or deforming leaves, some exuding a waxy secretion, and 

 others living free. The natural history of many species is quite unknown, 

 and the rearing of any from the egg or larva to the perfect state was com- 

 mended to the attention of entomologists, especially of those who have 

 reared Lepidoptera, as being equally interesting with insects of that order, 

 and furnishing an area for investigation as yet but little occupied. 



Mr. F. Grut exhibited a white downy nest from Jamaica, supposed to be 

 produced by some insect. 



Mr. H. Goss exhibited a dark variety of Cleora glahraria. 



Mr. C. 0. Waterhouse exhibited a new species of dragon-fly from Borneo, 

 belonging to the genus Gynacantha, which he proposed to call G. plagiata. 

 Tt differed from all its congeners, not only in its great size, but in the 

 unusual colouring of the wings, which were hyaline, with the whole anterior 

 border as far as the stigma broadly margined with pitchy brown, and with a 

 large patch of the same colour, only darker, across each wing near the apex ; 

 this patch on the hind wings extended a little along the posterior border. 

 The total expanse of the wings was 6^ inches ; the length of the posterior 

 wing, 3i inches. The specimen was a female. 



The Secretary read a circular from Dr. Buchanan White, of Perth, asking 

 entomologists to assist him with specimens of Hemiptera (especially exotic), 

 as he was engaged in working out that order of insects. 



Dr. Sharp communicated the following note : — 



" At the time Dr. Leconte was engaged in working out the classification 

 of the Rhynchophorous series of Coleoptera, I sent to him some New Zealand 

 species which appeared to me to be of interest, and he has now communicated 

 to me his opinions on these forms. As Dr. Leconte's highly important 

 memoir is now in the hands of entomologists, it is but fair that his views as 

 to these insects should be made known to those who are likely to find them 

 of assistance. ' I have looked,' he says, ' several times at the New Zealand 

 Rhynchophora you sent me, and find them so different from our North 

 American types that my opinion without the study of very extensive series 

 of genera from other countries would probably have but little value. Still 

 I will say what I think will be confirmed with more comparisons. Rhadi- 

 nosomus is a subfamily of Gurculionidce of equal systematic value with 

 SitonidcB and AlophidcB of my system, and indicates an affinity towards 

 BrerithidcB. Lacordaire has put it in an entirely wrong position, for the 

 mentum is small, the gular peduncle well developed, the maxillae exposed, 

 and the mandibles without scar and emarginate at tip. Psepholax is not 

 a Cryptorhynch, as indicated by Lacordaire, but a Scolytid of the tribe 

 Hylurgini, as is clearly proved by the last ventral segment surrounding the
