518 Mr. D.Pharp on some new 
elongate in the middle, the sides slightly curved; both 
front and hind angles distinct, although a little rounded ; 
it is of an obscure reddish colour; the surface dull and 
without sculpture, but covered by dense tomentum, which 
towards the sides is of an ashy colour. The elytra are 
rather elongate, and bear a much variegated tomentum ; 
they are very finely but distinctly striate ; the strie are 
not straight, but are a little irregular; except for the 
striz they have no sculpture. 
Beaten from dead branches of the Koa tree, at an 
elevation of 4000—5000 feet, on Haleakala, island of 
Maui, April and May, 1880. 
Xyletobius nigrinus, n. 8. 
Niger, opacus, pube subflavescenti tenuiter vestitus, 
antennis sat elongatis, articulis intermediis serratis ; 
elytris leviter inzqualibus, subtiliter sed conspicue 
striatis, striis leviter sinuatis. Long. 4 mm. 
Antenne a good deal longer than head and thorax, 
nearly black, even the 2nd joint is slightly angulate in- 
ternally, and the following joints are more distinctly so, 
but the 5th joint shows a slight peculiarity in this 
respect, as its inner margin is somewhat obliquely trun- 
cate; the 9th and 10th joints are each just distinctly a 
little longer and more slender than its predecessor, and 
are a good deal longer than broad; the 11th joint is 
slender, distinctly longer than the 10th. Head very 
sparingly pubescent, and rendered a little rough by fine 
extremely flat tubercles or granules. Thorax a good deal 
longer in the middle than at the sides, both front and 
hind angles a good deal rounded, and the former much 
deflexed ; the surface is conspicuously tomentose or finely 
pubescent, and towards the sides some excessively fine 
eranules may be distinguished. LHlytra rather deeply 
striate, the striz not punctate ; at some distance behind 
the base each has an oblique transverse depression, and, 
in passing through this, the striz are a little sinuate ; 
the tomentum is not dense, and seems to be more scanty 
towards the apex. Other sculpture than the striz is 
excessively indistinct. The legs, including the tarsi, are 
black. The middle coxe are distinctly separated. 
Found by beating dead branches of a tree whose 
name is unknown, at an elevation of 4000—5000 feet, 
on Haleakala, island of Maui.
