Coleoptera from the Hawaiian Islands. 521 
onwards each becomes a little longer than its prede- 
cessor, but the 10th is not longer than the 9th, is indeed 
even perceptibly shorter than it; 11th joint distinctly 
longer than 9th. Head shining black, almost without 
sculpture and pubescence. Thorax transverse, not much 
prolonged in front, the anterior angles greatly deflexed, 
not acute, even just a little rounded owing to a slight 
curve of the front margin; the hind angles very broadly 
rounded, the base very feebly sinuate on each side of the 
middle, the surface very polished and shining, with a 
very obsolete puncturation. Elytra very coarsely punc- 
tate, the coarse punctures placed on indistinct strie, and 
at the apex, especially towards the sides, the striza become 
more distinct and the punctures more indistinct. Legs 
obscure yellow, the femora darker. 
This species is remarkable among the Anobiade by 
reason of its polished, glabrous upper surface. 
Two specimens of this distinct species were cut out of 
a Koa tree, at an elevation of about 1000 feet, near 
Honolulu. 
Holcobius major, 0. 8. 
Nigro-fuscus, subtilissime pubescens, parum nitidus, 
antennis elongatis, fusco-rufis ; prothorace transversim 
subquadrato, dense pubescens, versus angulos anteriores 
tenuiter granulato ; elytris tenuiter pubescentibus, pro- 
funde striatis, striis parum distincte punctatis. Long. 
103 mm. 
Of robust, parallel, elongate form. Antenne elongate 
and slender, dusky red, feebly serrate internally; the 
outline of the outer margin of joints 5—10 slightly 
emarginate or concave ; 9th joint slightly longer than 
the 8th; 10th more slender and a little shorter than 9th ; 
11th slender, about as long as 9th. Head finely granu- 
late, and with a scanty, very delicate pubescence or 
tomentum. Thorax transversely subquadrate, but little 
longer at the middle than at the sides, these presenting 
a sharp edge till just before the front angles, when the 
edge ceases, so that the front angles appear notched ; the 
hind angles rounded, but not greatly ; the surface with 
a not very dense, but very fine, tomentum, and towards 
the front angles with fine, not very numerous, eranules. 
Elytra deeply striate ; the strie indistinctly punctured
