LEUCOPH^EA SURINAMENSIS. 



describes it:- -"La coque a la forme d'un cylindre 

 comprime, tres-long ; les quinze compartiments des 

 deux cotes y sont fortement indiques exterieurement 

 par des stries enfoncees. La suture est lisse et Ton 

 remarque que les compartiments des deux cotes se 

 joignent a la suture en ordre alternant, de sorte que le 

 compartiment de 1'un des cotes se case ton jours dans 

 1' angle forme par deux compartiments du cote oppose; 

 la ligne de jonction va par consequent en zig-zag. 

 L'oviscapte est couche horizontalement dans le dernier 

 segment de la femelle. Ses dimensions sont : longueur 

 8 mm., hauteur 2*8 mm., largeur 1'8 mm." 



VARIATION.- -So far as my own experience goes L 

 surinamensis varies little in colour and general appear- 

 ance, but may do so considerably in size. An imago 

 received from Kew Gardens, 29 September 1909, 

 measured only 16 mm. in length. Sopp has one 

 measuring but 15 mm., while another in his possession 

 measures 24 mm. Tarsal segments are sometimes 

 reduced to four. 



DATE. As this cockroach is found only under arti- 



/ 



ficial conditions in Britain, no doubt the same must be 

 said of its breeding habits as of those of B. orientalis 

 (vide p. 97). 



DISTRIBUTION.- -L. surinamensis is now a cosmo- 

 politan species, having spread, through the influence 

 of trade, from its tropical home to many other parts 

 of the globe. It has been noted from Britain, France, 

 Spain, Burmah, Amoy, India, Java, Philippines, China, 

 Senegal, Cayenne, Martinique, Central America, Brazil, 

 Mexico, United States, British Columbia, Honolulu,* 

 and no doubt several other places. 



HABITS AND BRITISH LOCALITIES. 



This cockroach seems to have been first recorded for Britain 

 by Burr,t Ghiermonprez having' sent him one of two taken 



De Bormans says it is found in Honolulu under stones; but it is not 

 very common, the males being- very rare.
