BLAckBURN AND SHARP—On some New Species and Genera of Colcoptera. 179 
Acalles angusticollis, n. sp.—Angustus, valde convexus, niger, grisco-squa- 
mosus, rostro piceo, antennis rufis; prothorace latitudine longiore, cum elytris 
minus argute longitudinaliter carinato, his basi angusto, lateribus rotundatis. 
Long. exc. rost. 831 m.m. 
Rostrum rather broad, closely punctate in front of the antennz, behind them 
squamose; club of antennz rather elongate, oval. Thorax much narrower than 
the elytra, a little constricted in front, and rather narrower in front than at the 
base, the sides a little rounded; it is closely covered with pallid depressed scales, 
and is indistinctly longitudinally costate, and the costz bear a few erect sete or 
scales, some of which are black in colour. Elytra covered with a pale squamosity 
like the thorax, and bearing each three or four rather indistinct costz, none of 
which reach the apex, and of which only the second commences at the base; across 
the middle is a narrow indistinct black fascia, and the upright scales seen on 
the costz are in front of this all pallid white, behind it some few of them 
are black. 
The specimen described, No. 410, was beaten from Koa trees on Haleakala, island of Maui; two 
individuals, much rubbed and considerably smaller, found by beating in the mountain forests of 
Honolulu, seem to me to belong to the same species.

Acalles mauiensis, n. sp.—Minus brevis; piceo-niger, setis nigris et cinereis 
intermixtis vestitus; elytris pone medium circum suturam bimaculatis; rostro 
tibiarum apice et tarsis rufescentibus; antennis testaceis; harum funiculi articulo 
secundo quam primo multo minore ; prothorace vix transverso, antice constricto, 
postice parum angustato, 8-sulcato, interstitiis inter sulcas fortiter inequaliter 
elevatis, lateribus parum rotundatis; elytris minus brevibus, a latere fortiter 
rotundatis, obscure striatis, striis obscure crasse punctatis, interstitiis 2° et 4° 
fortiter nec eequaliter elevatis. 
This species bears a good deal of resemblance to A. lateralis, Sh., though very 
much smaller. It is sufficiently characterized, I think, by the comparative size of 
the first two joints of the funiculus, the two large whitish spots, one behind the 
other along the suture on the hinder half of the elytra, and the irregularity of the 
elevated ridges on the thorax and elytra (each of those on the former consisting 
in reality of three short ridges placed in a longitudinal line, and the second 
interstice of the elytra rising gradually to a strong elevation just before the middle, 
and then abruptly ceasing altogether). 
A single specimen was beaten from Aleurites triloba, at an elevation of about 4000 feet, on 
Haleakala, Maui.
