ARMADILLIDIID^E. 



III. — Genus ARMADILLWIUM Brandt 



Four species of Armadillidium (vulgare Latr., pictum Brandt, 

 pulchellum Zencker and sulcatum M.-Edw.), are known from 

 Belgium the last two of which bave not yet occurred in Britain. 

 A fifth species, A. nasatum B.-Lund, is recorded below. 



I. — Armadillidium nasatum Budde-Lund. 



Armadillidium nasatum Budde-Lund, Crustacea Isopoda Terrestria, p. 51, 

 1885; Dollfus, Le Genre Armadillidium, p. 10, fig. 12, 1892; Stebbing, 

 Ann. and Mag. of Natural History, ser. 6, XV, p. 22, 1895; Norman, Ann. 

 and Mag. of Natural History, ser. 7, III, p. 57, pi. VI, figs. 5-8, 1899, 



A species recorded from France, Spain, Ilalyand the South West 

 of England. Farly this year (1907) Mr. Patience discovered that 

 A. nasatum lived commonly in green-houses at Glasgow, etc., 

 wliere, through his kindness I had the pleasure of first seeing the 

 species. I bave since found it in various British localities and in 

 Belgium. 



Belgium. — Several spécimens in bol-houses at Brussels and Ant- 

 werp, November 1907. 



The following Land Isopoda were also noted : Trichoniscus pusil- 

 lus Brandt, Oniscus asellus L., Philoscia muscorum Scop., Por- 

 cellio scaber Latr., P. pietus Brandt and Ratzeburg (one spéci- 

 men, Antwerp), P. dilatatus Brandt 'a few at Antwerp and in extra- 

 ordinary profusion at Brussels), Meloponorthus pruinosus Brandt. 

 and Cylisticus convexus Hartmann. 



Had time permitted we should undoubtedly hâve iaken other and 

 more interesting forms, but it must be remembered that the above 

 records are the results of a little more that two hours collecting and 

 that a good portion of this time was devoted to the Thysanoptera . 

 I should be very glad to bave the opportunity of examining any 

 woodlice from Belgian gardens and hot-houses, especially the smaller 

 species, the Trichoniscidtr.
