236 Mr. T. Vernon Wollaston on 
Teneriffe, Gomera, and Hierro, and which I cited as 
rather aberrant individuals of the Madeiran M. echi, are 
more in reality than a somewhat large variety of the 
M. seniculus (=tristis, mihi, nec Sturm); at any rate 
the only specimen to which I now have access belongs 
manifestly to that species: and if this should prove to be 
the case, it will follow that the M. echii has been observed 
hitherto only in Madeira. 
I may just state, however, that the typical M. echii 
(which occurs on the flowers and woolly foliage of the 
gigantic H. candicans of intermediate elevations, in the 
Madeiran archipelago) is certainly distinct from the 
(much smaller and darker-limbed) M. seniculus ; so that 
the note at p. 111 of my ‘Col. Atl”, which calls this 
point in question, requires to be qualified. 
(Sp. 312) Meligethes tristis. 
According to Mr. Rye this Meligethes is not the tristis, 
of Sturm, as I have hitherto imagined, but Hrichson’s 
seniculus—a species equally European in its range. 
Whether however it is attached to plants of the Hehiuwm 
group in the Atlantic islands, as it would appear to be in 
more northern countries, I am unable to say; though 
perhaps, on enquiry, this will be found to be the case. 
“The true tristis,’ Mr. Rye observes, “‘is more ovate and 
less depressed than the seniculus, as also broader, darker, 
and with less and lighter pubescence; its prothorax, too, 
is more contracted in front, its hinder tibize are wider, 
and the anterior ones are a trifle narrower.” Mr. Crotch 
was evidently mistaken when, recording (Proc. Zool. Soc. 
Lond. 371; 1867) the M. incanus from the Azores (on the 
strength of a single individual taken in Fayal), he re- 
marked that “the M. tristis of Mr. Wollaston’s work 
must probably be referred to it [%.e., to the incanus].” 
Whatsoever Mr. Crotch’s insect may be, the Madeiran 
and Canarian one at all events is totally distinct from the 
European M. incanus—which is very like the wmbrosus, 
but not so broad, most densely punctured, with its legs 
picescent, and its anterior tibize considerably dilated to- 
wards the apex—where there are three pretty conspicuous 
teeth externally. The corrected synonymy, therefore, of 
the species will stand thus :—
