are insects, moreover, of somewhat peculiar habits, being found 

 only, so far as I have myself observed, in extremely salt places, 

 such as the immediate vicinity of salt-works and other spots of 

 a very briny nature. 



I may just mention that the insect received from M. Deyrolle 

 as the Heterophaga ovata of Dejean's Catalogue, and which is 

 apparently identical with the species from the Cape de Verdes, 

 was also named by him as " Cadius crypticoides, Dej.;" but the 

 genus Cadius is altogether distinct from the present one, and 

 belongs in fact to another group of the Opatridce, namely, the 

 Stizopides, in which, inter alia, the anterior tibiae are dilated, 

 and more or less dentate along their outer edge.

 The present species is very closely related to one* which I 

 have taken abundantly in the neighbourhood of the Salinas, or 

 salt-pans, in the north of Lanzarote ; but its clypeus is a little 

 more developed and recurved immediately in front of the eyes, 

 its prothorax is perhaps a trifle more distinctly punctulated, its 

 elytra are just perceptibly more rugulose and very much less 

 evidently crenate- striated (the striae towards the suture being 



* I subjoin the following description of this nearly allied Canarian Ha- 

 lonomus, which will serve to point out its distinctions from the H.Grayii : — 



Halonomus salinicola, n. sp. 



H. fusco-piceus (fere niger), subopacus et setulis brevibus demissis cine- 

 reis irroratus ; capite dense rugoso-punctato, clypeo ad latera picescente 

 et mox ante oculos minus ampliato subrecurvo ; prothorace minute 

 punctulato, ad latera picescente ; elytris distincte crenato-striatis, inter- 

 stitiis minutissime punctulatis ; antennis nigro-piceis, basi vix rufescen- 

 tioribus ; pedibus fusco-piceis, tibiarum anticarum angulo externo magis 

 producto exstante. 



Var. ^, affinis [an species distincta?], vix minor, vix densius punctulatus 

 setosusque, antennis vix pallidioribus tibiarumque anticarum angulo 

 externo paulo minus exstante. 



Long. corp. lin. 24-vix 3. 



Habitat sub lapidibus prope salinas in Lanzarota boreali, valde gregarius, 

 a meipso et Dom. Gray mense Januario a. d. 1858 copiose repertus : 

 varietatis /3 exemplar unicum ad Maspalomas in Canaria Grandi australi 

 adhuc solum iuveui.
