CURCULIONID.E. 



The 0. bifurcatus was first taken by Mr. Gray and myself near 

 Puerto de Cabras in Fuerteventura, in 1858, where I again captured 

 it in 1859, Its Grand- Canarian habitat is the low sandy isthmus 

 between Las Palmas and the Isleta, where I met with a single 

 specimen of it, and where a second was found by Dr. Crotch during 

 the summer of 1864. 



Genus 231. MESOXENUS. 

 Wollaston, Trans. Ent. Soc. Lond. v. 395 (1861). 



718. Mesoxenus Monizianus. 



Pentarthrum Monizianum, Wott., Ann. Nat. Hist. v. 450 (1860). 

 Mesoxenus Moniziamis, Id., loc. cit. 396, pi. 19. f. 4 (1861).

Habitat Maderenses (Mad.} et Canarienses (Ten.), vel sub ligno an- 

 tiquo super terrain posito vel in ramis Euphorbiarum emortuis 

 in inferioribus rarissimus. 



Detected in Madeira proper (during 1859) by Senhor Moniz, who 

 found several specimens of it adhering to the underside of old boards 

 which were lying on the damp earth in his garden at Funchal. I 

 had myself, however, a year previously, met with a single example 

 of it at the Canaries, in a house above the Puerto Orotava in 

 Teneriffe, in which island the Rev. R. T. Lowe took a second (from 

 within a dead Euphorbia-stem at Garachico). But in spite of the 

 latter fact, I scarcely think that the species is normally attached to 

 the Euphorbias ; for the habits of the Mesoxeni seem to be those of 

 Pentarthrum, and precisely such as the very peculiar habitat which 

 was discovered for the present insect at Funchal by S r Moniz would 

 appear to indicate. 



719. Mesoxenus Bewickianus. 





Pentarthrum Bewickianum, Wott., Ann. Nat. Hist. v. 451 (1860). 

 Mesoxenus Bewickianus, Id., loc. cit. 397, pi. 19. f. 6 (1861). 



Habitat Maderenses (Mad.), sub ligno antique haud procnl ab nrbe 

 Funchalensi a Dom. Bewicke deprehensus. 



Found at a low elevation in Madeira proper by the late Mr. Be- 

 wicke, who captured it rather abundantly beneath old wood (in a dry 

 and crumbling state) which was lying on the ground in a shed at 

 the Praia Formosa near Funchal in company with the Hexarthrum 

 capitulum, Phlceophagus calvus, and Xylopertha barbata.
