174 Mr. T. Vernon Wollaston on the Euphorbia-infesting 



Leiparthrum inarmatum, WoU., Ann. of Nat. Hist. (Ser. 3) v. 



364 (1860). 

 Habitat in ramulis Euphorbiarum eraortuis, in ins. Lanzarota, 

 Canarid, TenerifFa, et Palmd parce captum. 



The present little Leiparthrum is, likewise, found in Madeira, — 

 where it was detected by myself, on the 2Srd of December, 1858, 

 in dead branches of the Eiiph. piscatoria between Point Oliveira 

 and the Brazen Head, to the eastward of Funchal. It was from these 

 examples that I draw out my diagnosis of the species in 1860 ; 

 nevertheless I had previously captured several (during January, 

 March and June of the same year) in Lanzarote, Grand Canary, 

 TenerifFe and Palma. So far as I have observed hitherto, both at 

 Madeira and the Canaries, it is quite peculiar to the wood of the 

 decayed Euphorbias. It may be at once known from the L. cur- 

 ium by its usually darker and less ferruginous hue (it being 

 generally nearly black in front but more piceous posteriorly), by 

 its less parallel outline (the elytra being slightly expanded, and 

 obliquely-subtruncated, at their apex, — where moreover they are 

 densely clothed with long and robust pile), by its untubercled 

 prolhorax, and by the comparatively large punctures, and raised 

 intestices, of its elytra.

Habitat TenerifFam, prope oppidum Garachico in caulibus Eu- 

 phorbiarum emortuis a Revdo. Domo. Lowe nuperrime detectum, 

 • — cujus in honorem speciem stabilivi. 



This very interesting and minute Leiparthrum has just been 

 communicated by the Rev. R. T. Lowe, who detected several 

 specimens of it in dead Euphorbia-stems, during April of the 

 present year, near Garachico, in Teneriffe. In its diminutive size 

 it misht at first sight be mistaken for a dwarfed state of the L. 

 inarmatum, but on closer inspection it is abundantly distinct from 

 that insect. Thus, it is not only smaller than the smallest examples 

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

 colorous) hue; it is also of a strictly cylindric outline (being 

 neither widened nor subtruncated posteriorly), with its prothorax
