TROGOSITID^E. 



Genus 103. EUROPS. 

 Wollaston, Ins. Mad. 149 (1854). 



320. Europs impressicollis. 



Europs impressicollis, Wott., Ins. Mad. 150, tab. iii. f. 2 (1854). 



, Id., Cat. Mad. Col 50 (1857). 



, Id., Trans. Ent. Soc. Lond. i. 145 (1862). 



, Id., Cat. Can. Col. 128 (1864). 



Habitat Maderenses (Mad., Des.) et Canarienses (ins. omnes), Eu- 

 phorbias emortuas vetustas copiosissime destruens. 



This insect is probably universal throughout these Atlantic islands 

 wherever Euphorbias are to be found ; for it is attached exclusively 

 to the rotten stems and branches of those singular plants. Never- 

 theless at the Madeiran Group it has been detected hitherto only in 

 Madeira proper and the Deserta Grande ; though at the Canaries it 

 has been met with abundantly in the whole seven islands of the 

 archipelago ; and I even found it in the little islet of Graciosa, off 

 the extreme north of Lanzarote. 



321. Europs duplicatus. 



Europs duplicatus, Woll, Trans. Ent. Soc. Lond. i. 146 (1862). 

 , Id., Cat. Can. Col. 129 (1864). 



Habitat Canarienses (Gom.\ in plantis putridis Euphorbia canariensis 

 praecipue degens. 



Detected hitherto only in Gomera, of the Canarian Group, where, 

 however, it is locally somewhat abundant within the putrid stems of 

 the Euphorbia canariensis.

Genus 104. TEMNOCHILA. 



Westwood, Zool. Journ. v. 231 [script. Temnoscheila~] (1835). 



322. Temnochila pini. 



Trogosita pini, Brulle, in Webb et Berth. (Col.) 70 (1838). 

 Temnochifa pini, Wott., Cat. Can. Col. 119 (1864). 



Habitat Canarienses (Can., Ten., Palma, Hierro), truncos antiques 

 Pini canariensis in pinetis perforans ; rarissima. 



This superb Temnochila, which may be regarded as the represen- 

 tative of the T. ccerulea of more northern latitudes, is confined to the 

 old Pinals of the Canarian Group ; and it will probably, therefore,
