Genus LEIPARTHRUM. 

 Wollaston, Ins. Mad. 294 (1854). 



Leiparthrum inarmatum, n. sp. 



L. breviter subovato-cylindricum fusco-nigrum et pilis rigidis (prse- 

 sertim postice) vestitum ; prothorace autice subattenuato inarmato 

 (t. e. tuberculis omnino carente) ; elytris profunde striato-punc- 

 tatis, interstitiis leviter elevatis, apicem versus plerumque paulo 

 dilutioribus necnon ad apicem obsoletissime subtruncatis. 

 Long. corp. lin. f-f . 



Habitat in ramis emortuis Euphorbia piscatorite, in inferioribus 

 Maderse crescentis, minus frequens. 



L. sbort and subovate-cylindrical (having the slightest pos- 

 sible tendency to be expanded behind, t. e. towards the apex of 

 the elytra), black or brownish-black ; and more or less clothed 

 with short, thick, rigid, cinereous, and somewhat scaly pubes- 

 cence. Prothorax a trifle more narrowed anteriorly than in the 

 L. bituberculatum, and also a little more coarsely alutaceous and 

 punctured; and without any appearance of the tubercles in 

 front, which are so evident in that species, as well as in the L. 

 mandibulare and L. curium. Elytra deeply and distinctly striate- 

 punctate (the punctures being large and well defined), and with 

 the interstices obscurely elevated ; a little more suddenly termi- 

 nated (or with a very slight tendency to be obliquely truncated) 

 at their apex where, moreover, the setae are rather longer and 

 coarser, and appear therefore to be more evidently disposed in 

 longitudinal rows. Limbs paler. 



The present insignificant little Leiparthrum was detected by 

 myself in the rotten stems of the Euphorbia piscatoria, in com- 

 pany with the two Aphanarthra described above, in the mari- 

 time district between the Brazen Head and Cani9O, to the east- 

 ward of Funchal, in which locality it was subsequently captured 

 likewise by Senhor Moniz and Mr. Bewicke. Its rather shortened 

 and apically-subtruncated form, in conjunction with its compa- 

 ratively deeply-sculptured elytra (with their large punctures and 

 raised interstices) and its untuberculated prothorax, will at once 

 distinguish it from its allies, from which, moreover, in its exclu- 

 sively (as I believe) Euphorbia-infesting habits it completely 

 recedes. 



Genus CRYPHALUS. 



Erichson, in Wiegm. Archiv, ii. 61 (1836). 



The diminutive insect described below I regard as a Cryphalus : 

 at any rate, after carefully mounting its antennse in Canada bal- 

 sam, I cannot satisfy myself, beneath the highest microscopic 

 power, that its funiculus is more than quadriarticulate. Indeed, 

 so excessively minute are the three transverse joints between the
