 Habitat in insulis Lanzarota, Fuerteventura, Teneriffaet Hierro, 

 sub cortice Euphorbiarum arido laxo latitans. 



Whether this insect be pecuhar to the Euphorbias, I cannot at 

 present undertake to say : nevertheless, since the few specimens 

 which 1 have detected hitherto were all found beneath the dead 

 outer fibre of those plants, it seems probable that it may undergo 

 its transformations, like so many other species, within the rotting 

 Euphorbia-stems. I have taken it in Lanzarote, Fuerteventura, 

 near Orotava and Taganana of TenerifFe, and in the lower district 

 of El Golfo on the west of Hierro. 



Fam. TOMICID^. 

 Genus Aphanarthrum. 

 Woll,, Ins. Mad. 292 (1854). 

 Some little qualification (though hardly, perhaps, correction) is 

 necessary, of my diagnosis of this genus as given in the " Insecta 

 Maderensia." Its funiculus is there stated, unreservedly, to be 

 3-articulate,^ — ^i. e., to consist of a large basal joint, followed by 

 livo excessively minute ones between it and the club; and certainly 

 in the exponent (the J. Euphorhice, from the higher elevations of 

 Madeira) for wliich the group was established 1 am still able to 

 detect what I believe to be an infinitesimal third joint at the base 

 of the capitulum, — though, from the oblique implantation of the 

 funiculus into the latter, this additional "joint" is only traceable 

 when the antenna is viewed in a particular direction. Still, this 

 third articulation (if such) is so diminutive that I would not be 

 absolutely certain that it is more than an apparent one. At any 

 rate this conclusion has been somewhat forced upon me lately 

 through my inability to count more than tivo funiculus-joints in
