graphical state of the European P. depressus ; but further material 

 would be necessary, for comparison, before such could be ascertained. 



. Genus 118. XENOSCELIS. 



Wollaston, Trans. Ent. Soc. Lond. i. 151* (1862). 



384. Xenoscelis deplanatus. 



Pristoscelis deplanatus, WolL, Hoc. cit. 152, pi. 7. f. 3 (1862). 

 Xenoscelis deplanatus, Id., Cat. Can. Col. 132 (1864). 



Habitat Canarienses (Ten., Palma, Hierro), sub fibris Euphorbiarum 

 laxis latitans. 



Detected in Teneriffe, Palma, and Hierro, of the Canarian Group 

 where it is locally common, beneath the outer fibre of the dead 

 Euphorbias. On one occasion, however, (in Palma) I took a single 

 example under the bark of a pine-tree; but as that is the only 

 instance (so far as I am. aware) in which the species has been 

 observed away from the Euphorbias, I believe that that particular 

 specimen must have taken shelter there accidentally, and I have 

 therefore no hesitation in regarding the insect as strictly of 

 Euphorbia-infesting habits. In Hierro it was captured abundantly 

 both by Mr. Gray and myself. 



Genus 119. NAUSIBIUS. 

 (Schaum) Redtenbacher, Fna Austr. (edit. 2) 998 (1858), 



385. Nausibius dentatus. 



Corticaria dentata, Mshm, Ent. Brit. i. 108 (1802). 

 Silvanus dentatus, Wott., Ins. Mad. 167 (1854). 



Id., Cat. Mad. Col. 54 (1857).

Habitat Maderenses (Mad.) et Canarienses (Lanz., Ten., Gfom.), in 

 domibus, certe ex alienis introductus. 



Clearly an importation into the islands, as indeed it is throughout 

 a large portion of the civilized world occurring (frequently dead) 

 amongst various articles of commerce, about houses and stores. In 

 such situations it is met with occasionally in Madeira proper ; and 

 it has been observed, under similar circumstances, in Lanzarote, 

 Teneriffe, and Gomera, of thp Canarian Group. 



* The genus is there published as Pristoscelis ; but it will be seen that subse- 

 quently (in my Canarian Catalogue) I altered it to Xenoscelis, the former name 

 having already been employed by Dr. Leconte.
