1139. Melansis costata. 



Phylax costatus, Brulle, in Webb et Berth. (Col} 69 (1838). 

 Melansis costata, Woll., Cat. Can. Col. 491 (1864). 



Habitat Canarienses (Can.), hinc inde in editioribus haud infrequens. 



Hitherto I have observed this insect only on the mountains of 

 Grand Canary, where it is locally far from uncommon at a rather 

 high altitude. On the ascent to the great Final above San Barto- 

 lome, in the central region of Tarajana, I met with it in tolerable 

 abundance. 



1140. Melansis angulata. 



Melansis angulata, Wbtt., Cat. Can. Col. 492 (1864). 

 Habitat Canarienses (Palma, Hierro), in intermediis rarissima. 



I captured about twenty examples of this well-defined species in 

 Palma, of the Canarian Group, beneath stones in the Earranco 

 above S ta Cruz, at about two miles from the latter. And a specimen 

 has been communicated by De Marseul, which was taken by M. de la 

 Perraudiere in Hierro*. 



Genus 343. HADRUS. 

 (Dej. Cat.) Wollaston, Ins. Mad. 502 (1854). 



1141. Hadrus alpinus. 



Hadrus alpinus, Wott., Ins. Mad. 502, tab. xi. f. 5 (1854). 

 , Id., Cat. Mad. Col. 156 (1857). 



Habitat Maderenses (Mad.), in intermediis editioribusque sat vul- 

 garis. 



Bather common in the intermediate and somewhat lofty altitudes 

 of Madeira proper, occurring (beneath stones) both in the sylvan 

 regions and above them ; but it does not appear to descend into the 

 lower districts. 



1142. Hadrus Paivse. 



Hadrus Paivse, Wott., Ann. Nat. Hist. vi. 50 (1860). 

 , Id. } Append. liy/j. op. 61. 



Habitat Maderenses (Mad.), in inferioribus prope oppidulum Porto 

 da Cruz adhuc tantum lectus. 



* The Hierro specimen has its costas just perceptibly less sharply developed, 

 and its hinder prothoracic angles more decidedly simple (or with no apparent 

 tendency to be subrecurved) ; but such slight characters are hardly worth noticing, 

 being scarcely appreciable.
