MADEIRAN COLEOPTERA. aL yéri 
appearance of an alutaccous sculpture, even beneath the microscope, 
shining, coarsely pubescent, and rather convex. Prothorax very 
convex ; almost equally rounded at the sides, and therefore broadest 
about the middle; and with faint indications of a dorsal channel. 
Elytra slightly rufescent about the shoulders. Abdomen but faintly 
diluted in colouring at its apex. Antenne and legs of moderate 
length ; the former rather robust, and brownish-piceous (their 
base being scarcely paler than the rest of the joints); the latter 
pale testaceous. 
The above Homalota is apparently a good deal allied to the plebera ; 
nevertheless it is rather larger and more shining than that insect ; 
its prothorax is convexer, not quite so short, more equally rounded at 
the sides (and therefore less truncated in front), obscurely channeled, 
much less evidently alutaceous, and with its punctures more remote ; 
its shoulders are slightly rufescent; and its limbs are somewhat 
paler. A single specimen of it was captured during May 1856 on 
the Pico dos Arieros, of Madeira proper, by Mr. Bewicke (by whom 
it was presented to the British Museum),—at an elevation of nearly 
6000 feet above the sea.

Homalota sodalis, Woll. [nee Erich., 1837], Ins. Mad. 554 (1854). 
coriaria (Miller), Kraatz, Nat. der Ins. Deutsch, ii. 282 (1856). 

Inhabits Madeira proper ; occurring principally at low elevations, 
and often abounding in the gardens of Funchal. It was wrongly 
referred to the sodalis of Erichson, in the Insecta Maderensia ; on 
which fact Dr. Kraatz, to whom I subsequently sent it for inspec- 
tion, makes the following remark: ‘“ H. coriaria, mihi, nec H. sodalis 
ab Erichsone descripta. Differt punctatura subtiliore, staturé minore, 
et masculorum structura abdominis.”’ 
502. Homalota umbratilis. 
Homalota umbratilis, Woll., Ins. Mad. 554 (1854). 
Inhabits Madeira proper, and is hitherto unique,—the single 
specimen having been captured by myself in the north of the island, 
during July 1850,
