CANAKIAN COLEOPTEEA.

out the archipelago, — its Euphorbia-mfesting habits rendering this 



the more certain ; nevertheless hitherto I happen to have met with 



it only in Lanzarote, Grand Canary, Teneriffe, and Palma, — though I 



have examined two specimens which were found by Dr. Crotch in 



Gomera. 



430. Liparthrum Lowei. 



Leiparthrura Lowei, Woll, Trans. Ent. Soc. Lond. i. 174 (1862). 



Habitat TeneriiFam et Gomeram, in ramis Euphorbiarum emortuis 

 degens. 



This excessively minute wood-borer was detected by the Rev. R. 

 T. Lowe, in dead Eiqjhorbia-stems, near Garachico, in the north of 

 Teneriffe, during April 1860. In the diagnosis of it, given in my 

 Paper (cited above) " on the ^it/^Aov6/«-infesting Coleoptera of the 

 Canaries," I have stated that " it is not only smaller than the smallest 

 examples of the inarmatum, but it is usually of a blacker (and quite 

 concolorous) hue, of a strictly cylindric outline (being neither ex- 

 panded nor subtruncated posteriorly), with its pi'othorax shorter and 

 sinuated along the extreme base, and with its elytra (the intei'stices 

 of which are not raised) less deeply punctured and without any ad- 

 ditional seta3 at their apex. Its limbs also are considerably darker 

 than is the case in that insect. Its structural characters are quite 

 those of Liparthrum , the proportions of its 4-jointed funiculus and 

 feet being precisely similar to what obtains in the other members of 

 the group. Its fore tibias, however, are not altogether unarmed, 

 there being two short, obtuse teeth on their outer edge." It occurs 

 likewise in Gomei'a, where a single example was found by Dr. Crotch ; 

 and we may expect it, therefore, to be pretty general amongst the 

 decayed Euphorbias.

I have, unfortunately, but a single individual of this insect to judge
