IX. Description of the male of Alcimus dilatatus, Fairm. 
By Caries O. WATERHOUSE. 
[Read 3rd May, 1875. 
THIS insect was originally described by Fairmaire (in the 
Rev. Zool. 1849, p. 416), from a female example, and as 
the male appears to be unnoticed, I subjoin a short de- 
scription. 
é. Latus, leviter convexus, obscure castaneus, nitidus ; 
mandibulez capite paulo longiores, curvate, apice atte- 
nuate, basi subtus tuberculo parvo, supra pone medium 
dente cylindrico recurvo armate. Caput subtilissime 
corlaceum, pone oculos dente parvo armatum. Thorax 
capite paulo latior, longitudine duplo latior, lateribus 
parallelis, marginibus incrassatis subcrenatis, angulis 
posticis rotundatis; supra subtilissime coriaceus, dorso 
fere levi. LElytra thoracis latitudini squantia, fortiter 
striata, striis impunctatis, interstitiis subplanis crebre for- 
titer punctatis.

$, var. minor. Mandibulz capite paulo breviores. 
Caput circa oculos parce fortiter punctatum, pone oculos 
rotundatum. Thorax transversus, antice paulo angus- 
tatus, nitidus, latera versus parce fortiter punctatus.

Hab.—Samoa Is. 
The large development is in Major Parry’s collection ; 
the smaller one is in the British Museum, and was col- 
lected by the Rev. S. J. Whitmee. Both specimens are 
from the same locality. The female was described from 
Wallis Island, a small island at some distance from the 
main island, but belonging to the Samoas.
