440 CANARIAN COLEOPTERA. 



likewise most minutely, remotely, and evenly punctiilated all over, 

 and for its pro thorax being rather coarsely margined at the sides and 

 (though less evidently so) in front. That it is correctly identified 

 with M. Brulle's E. curtus I am enabled to vouch for certain, having 

 examined his original tj^ies in Paris. 



The A. curtus is locally abundant on the mountains of Grand Canary. 

 I have taken it on the slopes above San Mateo, towards the Eoca del 

 Soucilho ; and during April 1858 it occurred in profusion, crawling 

 sluggishly across the pathway on the ascent to the Pinal of Tarajana, 

 above San Bartolome. 



b. Epipleuroi plica Jmmeralis brevissima. 



672. Arthrodes obesus. 



A. praecedenti paulo minor, subrotundatior ; carina frontali sensim 

 minus arcuatii ; prothorace ad latera et antice paulo minus grosse 

 marginato, anguhs anticis minus productis ; elytris evidentius (sed 

 minute) densiusque punctulatis et multo magis aequalibus (nee sul- 

 catis), plus minus leviter malleatis ; antoiniis picescentioribus. 



Var. fi. simiUhna [an species distincta?]. Elytris magis a^qualibus, 

 parcius et sensim etiam levins punctulatis ; fronte interdum minute 

 bifoveolata ; pedibus picescentioribus. [Ins. Palma et Hierro.] — 

 Long. Corp. lin. 3-5. 



Erodius obesus, Brulle, in Webb et Berth. {Col.) 63 (1838). 



Habitat in Teneriffa, varietate /3 ad Palmam et Hierro pertinentc. 



The six examples now before me agree sufficiently well, I think, 

 with M. Brulle's types, which I examined, and also with his " de- 

 scription," to leave little doubt that they are (at any rate the Tene- 

 riffan form, if not the " var. /3 " also) conspceific with his Erodius 

 ohesus. Apart from their possessing (at the humeral angles of the 

 elytra) a very short epipleural plica, which does not exist in the A. 

 curtus, the A. ohesus may be known from that insect by its rather 

 smaller size and perhaps somewhat rounder outline, by its frontal 

 keel being perceptibly less curved, by its prothorax being a little 

 more finely margined along the lateral and anterior edges, by its ely- 

 tra being more coarsely and closely (though, at the same time, very 

 minutely) punctulated, as well as much more even (being free from 

 longitudinal sulci, and apparently only a little malleated), and by its 

 antennae being rather more picescent. These remarks apply more 

 particularly to what I have regarded as the normal state of the species 

 (represented by the Teneriff'an indi\idual described from, and which 

 was communicated from S'^'^ Cruz by the Barao do Castello de Paiva) : 

 and I should perhaps add that the types which I inspected in Paris
