MADETRAN COLEOPTERA. 45 
obscurely disposed in rows; the alternate interstices indistinctly 
raised and interrupted, forming large but low nodules (in the 
usual positions), which are more or less brightly rufescent and 
confluent,—tending (when confluent) to shape-out a hinder fascia, 
and another, arched one, in front (in addition to a round patch on 
the disk of each elytron), the most distinct portion of which is 
about the scutellum ; the paler sete, moreover, being distributed 
upon the nodules and fasciz so as to give them a variegated 
appearance. Femora and tibia piceous: antenne and tarsi pale- 
ferruginous. 
Male smaller than the female; and with the tars? and claws much 
longer, slenderer, and less curved: the feet in both sexes, how- 
ever, being simple. 
This most distinct and elegant little Tarphius, which may be at 
onee recognized by its short, ovate outline, prettily variegated sur- 
face, and by the peculiar structure of its male feet (which are longer, 
slenderer, and less curved—both themselves and the claws—than 
those of any other members of the genus which I have as yet de- 
tected), is apparently one of the rarest of the Madeiran Coleoptera, 
and confined to the dense sylvan districts of intermediate eleva- 
tions, in the north of Madeira proper. I captured it very sparingly 
on the mountains both to the east and west of the Sao Vincente 
ravine, during the summer of 1855,—namely, at the Lombo de 
Vaca and the Lombo dos Pecegueiros. 
129. Tarphius compactus. 
Tarphius compactus, Woll., Ins. Mad. 139 (1854). 
Inhabits the sylvan districts of Madeira proper, particularly 
towards the north of the island. I stated in the Jnsecta Maderensia 
that this species was less distinct than most of its congeners. <A 
further acquaintance with it has satisfied me that it is as well-cha- 
racterized as any of them,—its much-incrusted surface and longer 
antennse (to which last, attention was not drawn in that volume) 
giving it, apart from other features, a somewhat peculiar appearance. 
130. Tarphius nodosus. 
Tarphius nodosus, Woll., Ins. Mad. 140. tab. iii. f. 6 (1854). 
Inhabits the sylvan districts of Madeira proper, especially towards 
their upper limits. Locally abundant. 
131. Tarphius cicatricosus. 
Tarphius cicatricosus, Woll., Ins. Mad. 141 (1854). 
Tnhabits the sylvan districts of Madeira proper, in company with 
the preceding. Rare.
