1^6 The Irish Naturalist. September, 



of Trichorina tomenfosa taken in Kew Gardens, we are not 

 aware that any notice of this species having been taken in 

 the British Islands has hitherto been pubhshed. 



Nagara nana, Budde-Lund. 



Of this species we obtained only a single specimen in the 

 Belfast Botanic Gardens, which has been retained by Prof. 

 Budde-Lund, who writes that it agrees with his published 

 description of the species, from which we take the following. 

 " Nagara is a sub-genus of Porcellio. N. nana — Surface 

 minutely granular especially on the head and in the middle 

 of the first segment ; the rest of the surface thickly covered 

 with minute scales. Antennje scarcely exceeding in length 

 one-third of the body ; all the joints of the peduncle thickish, 

 the proximal joint of the fiagellum small, one-third the 

 length of the distal joint. Lateral lobes of the head rather 

 small, median lobe prominent and slightly curved forwards. 

 Clypeus slightly convex. The posterior edges of first and 

 second body segments strongly curved, of the third segment 

 nearly straight. Abdominal segments i and 2 short, the 

 lateral plates of segments 3, 4, and 5 mediocre, separated, 

 roundly triangular. Telson slightly projecting beyond the 

 lateral plates of last abdominal segment, triangular, with its 

 sides curved broadly inwards, slightly concave above, with 

 sharpish apex. Colour grey, with paler oblong spots on the 

 body ; segments forming a pale longitudinal line ; legs 

 white; antenn;e often whitish. Length, 4 -5-4 -7 mm., 

 width 2 '3-2 '5 mm. This species was found by Dr. 

 Voeltzkow at Lokube on the island of Nossibe, off the N.W. 

 coast of Madagascar, in 1895, and by Commandant Dorr, at 

 Ankarefa and Tamatave, East Madagascar, in 1897." So 

 far as we can ascertain, these are the only published re- 

 ferences to this species. 



Hillsborough, Co. Down.
