Atlantic Coleoptera. 239 
As I have already stated elsewhere, this fine Meligethes 
is far from uncommon in the two eastern islands (Lanza- 
rote and Fuerteventura) of the Canarian Group, but so 
far as I have observed hitherto it seems to be scarcer in 
the more western parts of the archipelago: nevertheless 
I have met with it sparingly in Teneriffe. Although 
with much the same brassy-green hue and pallid limbs 
as its Madeiran ally (the M. varicollis) , it differs in being 
much more coarsely, and rather less closely, punctured 
than thatinsect, and clothed with arather shorter sericeous 
pubescence; its prothorax (which is a trifle less rounded 
at the sides, and with consequently the hinder angles 
somewhat less obtuse) is apparently always concolorous 
(never being diluted in hue towards either external edge); 
its antenne are appreciably shorter; and the outer edge 
of its anterior tibie are more powerfully (though un- 
equally) serrate.

p. 118 (genus Monoroma). 
Motschoulsky has lately informed us (vide Bull. Mosc. 
196; 1869) that he considers Lacordaire was mistaken 
in citing oniy three joints for the tarsi, and ten for the 
antennz, in Monotoma, and in consequence placing 
it amongst the Latridiide ; for, in point of fact, the feet 
are tetramerous and the antenne (as he asserts) com- 
posed of eleven articulations: and he argues therefore 
that, both in structure and habit, it belongs more properly 
to the Colydiens “a cété des Pycnomérides.” Although 
I believe that Motschoulsky is incorrect as regards the 
antenne, which seem to me to have but ten joints (the 
terminal one being completely lost, or swallowed-up, 
within the apex of the one-articulated club), he is 
evidently right about the tarsi; and the conclusion which 
he comes to about the affinities is exactly the same as I 
had myself arrived at twelve years before (vide Cat. Mad. 
Col. 67) , though I did not so far deviate from the usually- 
received opinion as actually to place the genus amongst 
the Colydiade. In my ‘ Canarian Catalogue’ however, 
in 1864, I made the alteration, and during the following 
year adopted the same position in my ‘ Coleoptera Atlan- 
tidum’—though assigning it to a separate family, instead 
of to the Endophleeideous section of the Colydiade.
