» Fab., Syst. Eleu. i. 93 (1801). 
Ellipsodes glabratus, Woll., Ins. Mad. 486, tab. xi. f. 2 (1854). 
Inhabits the mountains of Madeira proper, ranging from about 
1500 feet above the sea to the extreme summits of the peaks. 
433. Ellipsodes oblongior, n. sp. 
Ellipsodes glabratus, var. 8, Woll., Ins. Mad. 486 (1854). 
Inhabits Porto Santo and the two Southern Dezertas, occurring 
beneath stones in grassy spots of a high elevation. Rare. Although 
recorded in the Insecta Maderensia as the Dezertan form of the 
E. glabratus, I am induced to regard it now as specifically distinct 
therefrom, through the fact of my having discovered it (during the 
summer of 1855) in Porto Santo and the Southern Dezerta, likewise ; 
and it seems too much. to assume, that the local influences of those 
three islands should be of such a similar nature as to produce exactly 
the same modification from the Madeiran type. Nevertheless I am 
by no means convinced that it may not be a phasis of that imsect ; 
for, although the more oblong outline (especially perceptible poste- 
riorly), the somewhat paler antenne, the less deeply and more 
remotely punctured surface, and the tendency which its larger 
elytral punctures possess of being disposed in obscure longitudinal 
rows, would seem to remain constant both in Porto Santo and on the 
Dezertas, its alutaceous structure is apparently subject to variation,— 
being exceedingly evident in the specimens from the Dezerta Grande, 
less so in those from Porto Santo, and still less in the Bugian ones. 
The tibiz, also, are more darkly infuscated upon the Southern than 
upon the Central Dezerta: still, after a careful consideration of all its 
characters (both constant and inconstant), I think we have scarcely 
sufficient evidence for concluding it to be specifically identical with 
its Madeiran ally.
