Palma. It was also captured in Gomera (near San Sebastian) by 

 Mr. Gray and (at Hermigua) by Dr. Crotch.

Habitat in Fuerteventura, TenerifFa et Palma, bine inde vulgaris. 



The common European 0. pygmams is locally abundant at the Ca- 

 naries. I have taken it in (the Rio Palmas of) Fuerteventura, (near 

 S''' Cruz and Orotava, and at the Ag-ua Garcia of) TenerifFe, and (in 

 the Barranco de San Juan of) Palma. 



140. Ochthebius lapidicola, n. sp. 



0. elongato-ovatus, brunneo-piceus, vix metallescens, subopaeus ; ca- 

 pite prothoraceque dense punctatis et valde rugulosis, iUo trian- 

 gidari, utrinque late et profunde impresso, hoc canaliculate necnon 

 utrinque juxta canaliculam longitudinaliter bifoveolato ; elytris mi- 

 nutissime et parce pubescentibus, profunde et rugose punctato-stri- 

 atis; pedibus brevibus, robustis, ferrugineis. — Long. corp. lin.l-ll. 



Habitat Teneriffam et Palmam, rarissimus. 



A very remarkable Oclitliehius, and well distinguished at first sight 

 by its brownish-piceous, nearly opake and almost unmetaUic surface, 

 by its exceedingly rugose and deeply foveolated head and prothorax 

 (the former of which is triangular, being more regularly widened 

 behind than is the case with the Oc7if7ie6w. generally), by its rough 

 and coarsely punctate-striated elytra, and by its short and robust 

 legs. It is somewhat aUied to the 0. rugulosus from Porto Santo, 

 but totally distinct from it specifically. Of the only three specimens 

 which I have seen, two were captured by myself from under small 

 stones at the edges of the little stream (near its junction with the 

 sea) in the Barranco de San Juan, towards the north-west of Palma, 

 on the 28th of May 1858 ; and the remaining one by Dr. Crotch (at 

 Ycod el Alto) in TenerifFe.
