fishery. He made a most interesting excursion to Flan nan 

 Islands, which lie in the Atlantic, west of the Isle of Lewis, 

 and saw there the puffin {Fratevcula artica) in countless 

 numbers. 



Mr. West exhibited a specimen of the snake-fly (Rhaphi- 

 diuni), and also the homopteron, Pediopsis fuscinervis, both 

 from West Wickham. 



Mr. Clark exhibited a photograph of the egg of Eubolia 

 cervinata.

Mr. Malcolm Burr exhibited a large number of species of 

 the Orthopterous family Eumastacidae, and contributed the 

 following note : 



" The Eumastacidae are a curious family of Acridiodea 

 confined to the tropics, characterised inter alia by the short 

 antennae ; but one anomalous genus has long clavate antennas, 

 and is also peculiar in that it occurs in Palaearctic Asia. 

 The family includes many strange forms, imitating dried 

 leaves and other insects, even small dragon-flies. (See 

 Erucius agrionides, etc.). They seem to be rare insects, and 

 are only brought home by collectors in small numbers. The 

 African forms, Thcricleis, are, with one exception, quite desti- 

 tute of organs of flight. The Chorcetypi are almost entirely 

 Asiatic, a few species being found in Africa. One genus 

 alone is Australian. The Eumastaces are found in the 

 Neotropical portions of America, Africa, and Asia. Two 

 years ago little over thirty species were described ; now 

 almost one hundred are known to science." 



The exhibit was admirably illustrated with detailed draw- 

 ings by Mr. E. H, J. Schuster, of Oxford. 



Mr. Burr also exhibited the specimens of Orthoptera which 

 had been brought from Socotra by Mr. Ogilvie Grant, being 

 a portion of the result of the recent expedition. The exhibit 

 was interesting from a geographical point of view rather 

 than from the number of new species. There seemed to be 

 strong evidence of an overlapping of the Ethiopian and 

 Palaearctic regions. 



Mr. Sauze exhibited a large number of insects of all orders 

 taken during his holiday in July at Bournemouth and neigh- 

 bourhood. The species were : — Cupido \_Lyccena'] minima, 

 from Totland Bay ; Hesperia actceon, from Lulworth and
