174 MADEIRAN COLEOPTERA. 
in its head being less perceptibly alutaceous, beneath the microscope, 
and more remotely punctulated. 
I first detected it on the rocky declivities just below the summit 
of the Pico Branco, in the north of Porto Santo, early in May 1855, 
—where it was tolerably abundant amongst the earth at the roots of 
grass; though, from its habit of secreting itself in the soil, it was 
not easy to procure. And in the following month I obtained a single 
specimen from beneath a stone on the Ilheo Chao; as also a con- 
siderable number on the Southern Dezerta, or Bugio (on the steep, 
sloping buttresses immediately to the south of the cavern), under 
precisely similar circumstances as in Porto Santo. It has been ex- 
amined by Dr. Kraatz, of Berlin, who regards it as undoubtedly new. 
491. Homalota granulosa. 
Homalota granulosa, Woll., Ins. Mad. 548 (1854). 
Inhabits Madeira proper, occurring in moist places throughout the 
sylvan distiicts,—though principally at a lofty elevation. Rare. 
492, Homalota obliquepunctata. 
Homalota obliquepunctata, Woll., Ins. Mad. 549 (1854). 
Inhabits Madeira proper, occurring amongst shingle at the edges 
of the streams at intermediate altitudes. 
493. Homalota luridipennis. 
Bolitochara luridipennis, Mann., Brachel. 77 (1831). 
Homalota elongatula, Hrich., Gen. et Spec. Staph. 90. var. C. a (1839). 
luticola, Woll., Ins. Mad. 549 (1854). 
—— luridipennis, Kraatz, Nat. der Ins. Deutsch. ii, 221 (1856). 

Inhabits Madeira proper ; occurring sparingly amongst the wet soil 
at the roots of Marchantia polymorpha, L., and other plants, at the 
edges of the waterfalls (especially in the north of the island). The 
title of luticola, under which I described it in the Insecta Maderensia, 
has to sink into a synonym,—my original specimens having been 
subsequently examined by Dr. Kraatz, who has identified them with 
the luridipennis of Mannerheim. 
494. Homalota gregaria. 
Homalota gregaria, Erich., Gen. et Spec. Staph. 87 (1839). 
‘ Tachyusa immunita, zd., Gen. et Spec. Staph. 916 (1839).

Inhabits Porto Santo, abounding amongst stones and shingle at the 
edges of the streams,
