266 CANAKIAN COLEOPTERA. 



above the Agua Mansa (at an elevation of more than 7000 feet above 

 the sea). The individual from the latter locality is altogether a Httle 

 darker than those from the former, and has its prothoracic tubercles 

 a trifle more evident ; but I can detect nothing about it to warrant 

 the suspicion that it is specifically distinct. A Teneriffan example 

 has also been communicated by Dr. Crotch. 



428. Liparthrum curtum. 



Leiparthrum curtum, WoN., Lis. Mad. 298 (1854). 

 , Id, Cat. Mad. Col. 97 (1857). 



Habitat insulas Canarienses, in Gomera sola adhuc hand detectum. 



The L. curtum, which likewise occurs in Madeira, and (on the 

 average) at a rather lower elevation than the hituhcrcidatum, is 

 almost certainly universal at the Canaries, — though I did not happen 

 to meet with it in Gomera, during our short visit to that island : but 

 in Lanzarote, Fuerteventura, Grand Canary, Teneriife, Palma, and 

 Hierro I have captui'cd it, more or less abimdantly. It is foimd 

 more particularly beneath the old and loosened bark of palings, 

 gates, tkc, and in the dead Eiq)horbia-stejns ; and it is, aj^parently, 

 less strictly sylvan in its habits (or, at all events, less peculiar to the 

 laurel-districts) than the last species. It may be known from it by 

 its outline being relatively rather shorter and broader, by its paler 

 hue, and by its antenna?, mandibles, and prothorax being a trifle 

 more developed, — the last, also, having the pustules of its anterior 

 portion considerably smaller, and indeed often nearly imperceptible. 



429. Liparthrum inarmatum. 

 Leiparthrum inarmatmu, Wall, Ann. Nat. Hist. v. 364 (1800). 

 Habitat Lanzarotam, Canariam, Teneriflam, Gomeram et Palmam, 

 ramos Euphorbiarum emortuos parce destruens. 



This little Liparthrum, which seems to be peculiar to the branches 

 and stems of the dead Euphorbias, and which (Uke the last two spe- 

 cies) occurs also in Madeira, may be known by its short and poste- 

 riorly-obtuse outline ; by its jirothorax being a good deal developed, 

 though rather acuminated in front, and quite free from anterior pus- 

 tules, or tubercles ; and by its elytra being somewhat wide, and sud- 

 denly truncated, at their apex, very deeply striate -punctate (the 

 punctures being large and conspicuous), with their interstices per- 

 ceptibly elevated, and with theii* pubescence comj)aratively long 

 (especially behind) and very decidedly arranged in longitudijial rows. 

 Like the L. curtum, it will probably be found to be universal thi'ough-
