DUBLIN MICROSCOPICAL CLUB. 



October 12. — The Club met at Leinster House. 



J. Cr. Rhynehart shov/ed preparations of the head and jaws 

 of the larva of Triochcera relegationis which he had found feeding in rotten 

 turnip. He demonstrated the characteristic structure of the mandibles 

 and maxillae, and pointed out the presence, in association with the 

 conspicuous hypopharynx, of a pair of spinose lobes that might be 

 regarded as maxillulae. 



Prof, G. H. Carpenter showed preparations of the thoracic air-tubes 

 of Irish Hive-bees, in which adults, eggs, and nymphs of the small mite 

 Tarsonemus Woodi were present. This mite has been recently described 

 by Dr. Rennic {Trans. R. Soc. Edinh. vol. lii., 1920, pt. 4), as the causal 

 organism of " Isle of Wight " disease in Hive-bees. 



NOTES. 



ZOOLOGY. 



Qymnetron squamicolle Reitter, a Beetle new to the 

 Britannic List. 



On June i6th, 1902, I swept up in a damp spot at Glencar, Co. Kerry 

 a red Gymnetron unknown to me, but which I was subsequently told was 

 a red form of G. beccabungae. I accordingly recorded it as such {Irish 

 Nat. xii., 1903, p. 65), but have always regarded this identification with 

 considerable doubt, and have kept the insect in a space to itself in my 

 cabinet. Recently I sent it with some other beetles to my friend Major 

 Sainte Claire Deville, and he has returned it, stating that it is Gymnetron 

 cquamicolle Reitter. 



Reitter described the species from Berlin Verh. Naturf. Ver. BrUnn 

 xlv., 31 (1907) ; it occurs in the south of Norway, and Major Deville 

 takes it in Prance. He tells me he is not surprised that it has been 

 taken in our Islands, and thinks it will be found in England, as well 

 as Ireland. However this may be, the species has not been recorded from 

 the British Isles heretofore. 



G. squamicolle is a very pretty insect, the thorax is thickly clothed 

 with yellow scales, the elytra are red with the base , suture and sides 

 narrowly black, and the legs are red with black tarsi. I shaU be in- 

 terested to hear if this species is taken in any other part of Ireland.

On the nth instant a Death's head moth flew into the room of Miss 

 Linehan, the housekeeper at Lambay, and was caught by her.
