DUBLIN MICROSCOPICAL CLUB. 



February 13.— The Club met at Leinster House. 



Prof. G. H. Carpenter (President), in the chair, showed a new 

 species of bristletail (Thysanuran), Pramachilis hibcrnica, from Lambay. 

 Details of this insect have been described and figured in the Irish 

 Naturalist (vol. xvi., 1907, pp. 55-6, pi. 16). 



F. W. Moore exhibited a section of part of the labellum of Angracum 

 pellucidum from W. Tropical Africa. In this species the lip is delicately 

 fringed, and extremely thin, in pans reduced to one cell. In the cells 

 close to the edge there are numerous clusters of crystals (raphides).
