CAN ASIAN COLEOPTERA. 253 



diagnosis has been compiled was captured by myself in the east of 

 Palma (on the mountains between Galga and the sea), on the 24th 

 of May 1858. 



Genus 169. DINODERUS. 

 Stephens, Man. Brit. Col. 203 (1839). 



408. Dinoderus bniiineus. 



D. cylindricus, pieeo-bninneus, fere opacus, ubique densissime et 

 grosse rugoso-asperatus, breviter et parce sed in limbo longius 

 fulvo-pubescens ; prothoraee antice subangustato et valde mucro- 

 nato, postice dense granulato truncate ; elytrorum granulis magnis 

 sed vix subseriatim dispositis ; antennarum clava tarsisque paulo 

 magis testaceis. — Long. corp. lin. 2-2|. 



Dinoderus brunneus, Woll.,Ann. Nat. Hist. (3rd series) ix. 440 (1862). 

 Habitat in pinetis Teneriffae et Palmse, truncos Pini canariensis 

 emortuos destruens. 



I am doubtful whether this Dinoderus is more, in reaKty, than a 

 local phasis of the European D. substriatus, — from which it seems to 

 differ merely in its rather smaller size, narrower outline, and browner 

 hue, in the sculpture of its elytra being somewhat closer and not quite 

 so coarse, and in its prothorax being relatively a trifle narrower in 

 front, less dilated in the middle and more truncated at the base — 

 the hinder angles being rather less rounded off. It seems to be ex- 

 ceedingly rare, or at all events local, being confined (so far as I 

 have observed hitherto) to the rotten trunks of the Pimis canariensis, 

 at intermediate and somewhat lofty elevations. In such positions I 

 have taken it at the Agua Mansa in Teneriife, and high up in the 

 Barranco above S*^^ Cruz in Palma. 



Fam. 42. CIOIDiE. 



Genus 170. CIS. 

 Latreille, PrSc, des Caract. Gen. des Lis. 50 (1796). 



409. Cis lauri. 



Cis lauri, Woll, Ins. Mad. 282. tab. v. f. 7 (1854). 

 , Id., Cat. Mad. Col. 94 (1857). 



Habitat in lauretis Teneriffae, hinc inde sat vulgaris. 



The C. lauri, so common in the laurel-regions of Madeira, occurs 

 in similar spots at the Canaries — where, however, it seems to be 

 both more local and less abundant. Hitherto I have observed it only 

 in the woods of Las Mercedes and the Agua Garcia, in Teneriffe ;
