stages of the pupa ; (2) that the subcostal trachea at quite a 

 late stage emitted a branch to join the radial vein, where it 

 either united with or took the place of the radial trachea} ; 

 (3) that the median trachea at a late stage emitted a branch 

 to join the third median vein, which it entered and apparently 

 took the place of the first branch of the radial trachea. 

 Mr. Merrifield, Mr. Hampson, and Dr. Sharp took part in 

 the discussion which ensued. 



Mr. E. E. Green remarked that in the Trans. Ent. Soc, 

 1881, page 601, there was a short paper by the late 

 Prof. J. 0. Westwood, describing a curious little insect from 

 Ceylon under the name of Dyscritina longisetosa. Prof. 

 Westwood believed his t}^ical specimens to be immature. 

 Mr. Green exhibited what he supposed to be a later stage 

 of the same species. He said his example differed in some 

 particulars from Westwood's description and figure — notably 

 in the proportions of the caudal appendages. Prof. West- 

 wood pointed out the affinities of Dyacritina to the Forfi- 

 culidfB. This was very apparent in the specimen under 

 consideration. Putting aside the nature of the caudal 

 appendages the insect was in all particulars an earwig- 

 The present specimen was taken in the Punduloya district 

 of Ceylon, at an elevation of about 4,000 feet, Mr. Green 

 said he had more than once seen this insect under loose 

 pieces of bark and in crevices of rocks, and had always 

 been struck by its likeness to an earwig both in appearance 

 and habits. Mr. McLachlan, Dr. Sharp, Mr. Gahan, 

 Mr. Blandford, and Mr. Hampson made some remarks on 

 the subject 



Mr. 0. E Janson exhibited a Goliath beetle, from the 

 Upper Congo, which he believed to be the male of Goliathus 

 rimiis, Kolbe, described from a unique female example in the 

 Berlin Museum. 



Mr. Blandford called attention to a case of the eye of a 

 boy affected with inflammation caused by the hairs of the 

 larvje of Lasiocampa rnbi. The attack recurred after an 

 interval of nineteen weeks, and in several continental cases 

 this recurrence of the attack had been found to take place, 

 and in some cases permanent injury to the eye had followed.
