Ferdinand Grut, F.L.S. — The news of the death of Mr. Grut, Honorary 

 Librarian to the Entomological Society of London, on July 19th, aged 71, will come 

 upon the Fellows of the Society, and a large circle of private friends, as a shock. 

 Although not in good health for a long time, he was constantly present at the 

 Society, and at the meeting on July 1st he seemed better, and in better spirits, than 

 usual. This is a preliminary announcement.

Entomological Society of London: July \st, 1891. — Fbederick; 

 DttCane Godman, Esq., M.A., F.R.S., President, in the Chair. 



The Rev. John Isabell, of St. Sennen Rectory, Penzance, was elected a Fellow 

 of the Society. 



Mr. Jacoby exhibited a specimen of a species of Coleoptera belonging to the 

 family GalerucidcB, with the maxillary palpi extraordinarily developed. 



Canon Fowler, on behalf of Mr. Wroughton, Conservator of Forests, Poona, 

 exhibited specimens of a bug imitating an ant, Polyrhachis spiniger, and a spider 

 imitating a species of Mutilla, and read the following notes : — " I have taken a good 

 many specimens of a bug which has achieved a very fair imitation of Polyrhachis 

 spiniger (under the same stone with which it may be found), even to the extent of 

 evolving a pedicle and spines in what, were it an ant, would be its metanotum. 

 Curiously enough, however, these spines are apparently not alike in any two speci- 

 mens. Is it that this bug is still waiting for one of its race to accidentally sport 

 spines more like those of F. spiniger, and thus to set the ball of evolution rolling 

 afresh ? or is it that the present rough copy of spiniger' s spines is found sufficient to 

 deceive ? The bug has also been found in the Nilgherries. Mr. Rothney remarks 

 on the above species : — ' I have not found the species mimicking Mutilla ; but in 

 Calcutta and Barrackpoi'e, where P. spiniger is a tree-ant, forming its net by spinning 

 together the twigs of a shrub, the mimicking bug also assumes arboreal habits, and 

 may be found on the trunks of trees with the ants.' " 



Mr. PoiTitt exhibited living specimens of Fupithecia extensaria and Geometra 

 smaragdaria : the position assumed by the former proved conclusively that it had 

 rightly been placed in the genus Eupithecia. 



Mr. Crowley exhibited two specimens of a Papilio from the Khasia hills, be- 

 longing to an undescribed species allied to P. Papone, sub-generic section Chilades. 

 Col. Swinhoe remarked that he possessed a specimen from Northern Burmah. Mr. 

 Moore and others took part in the discussion which followed. 



Mr. Dallas Bccching exhibited a specimen of Plusia moneta, recently taken by 

 himself at High Woods, Tonbridge, and specimens of Gonepteryx Cleopatra, lent 

 him for exhibition, which were alleged to have come from the same locality. 



Ur. T. A. Chapman exhibited the larva of Micropteryx calthella, and read the 

 following notes : — " The larva were obtained by placing moths in a cage with damp 

 moss, diad Ituves, and otlier debris off the surface of the ground. Into this the
