462 CANARIAN COLEOrTERA. 



during January 1858, and subsequently by myself at Oliva in March 

 of the following year ; and I possess a specimen which was captured 

 in the same island by M, Hartung. It may readily be known by 

 its rather large size and thick, oblong-ovate body, by its subopake, 

 densely punctulated surface, and by its head having the longitudinal 

 plait on either side (adjoining the eye) greatly raised or developed. 

 Its epistome is produced in front into a robust subangulated point ; 

 and its prothorax has the sides slightly rounded, the basal angles 

 scarcely more than right angles, and the anterior ones acute. 



700. Thalpophila Deyrollii, n. sp. 



T. oblonga, crassa, aterrima, polita ; capitc prothoraceque dense et 

 (prcesertim illo) sat profunde punctatis, epistomate antice minute 

 sed acute mucronato ; prothorace brevi, transverso, ad latera leviter 

 rotixndato, angulis posticis subrotundate subrectis ; elytris minute 

 punctulatis et postice plus minus e^ddenter sed i)arco tuberculatis, 

 angidis humerahbus hand porrectis ; antennis pedibusque brevius- 

 culis. 



Variat in insula parva "Lobos" dicta (juxta Fuerteventuram bo- 

 realem) elytris grossius asperato-tuberculatis ; necnon in insuhi 

 " Graciosa " (juxta Lanzarotam borealcm) punctura omnino sub- 

 tiliore et subparciore. — Long. corp. lin. 3-4. 



Hegeter politus, Hart. \jiiQcBr.'],Geolo(f. Verhaltn. Lcmz.und FuerLUl. 



Halntat Lanzarotam et Fuerteventuram, sub lapidibus ubique vul- 

 garis. Species in honorem Dom. A. DeyroUe, Parisii, Coleopterorum

Although one of M. Brulle's (two) types of his Hegeter politus ap- 

 peared to me, when I examined them in Paris, to ho perhaps refer- 

 able to this insect, nevertheless, as the other was manifestly nothing 

 but the large and subglabrous state of the //. mnaroides (found in 

 the Vale of Orotava), and since his description (if such indeed it may 

 be called) applies most evidenthj to the latter, I cannot possibly iden- 

 tify the present species with his Hegeter politus. Moreover even that 

 " one " example (and which has nothing in common with his " dia- 

 gnosis") is labelled " Teneriffe"; which renders it more than probable 

 that even it is in reality distinct from the Thalpophila now under 

 consideration : but, be this as it may, M. Brulle's few words which 

 take the place of a description are so decidedly applicable to the Tene- 

 riifan Hegeter which I have recorded as a larger and somewhat more 

 shining form of the common amaroides, that no number of (so-called) 

 " types," afterwards assigned to them, could make them tally with 

 this well-marked Thalpophila, which is apparently quite peculiar to 

 the eastern portion of the archipelago.
