BLACKBURN AND SuarrP—On some New Species and Genera of Coleoptera. 183 
Brachypeplus torvus, n. sp.—Haud latus; convexiusculus; nigro-eneus, an- 
tennis pedibus prothoraceque lateribus rufescentibus, tarsis nigricantibus ; pube- 
scens, sat nitidus ; capite prothoraceque obscure crebrius punctatis, hoc rotundato, 
fortius transverso ; elytris subtiliter confuse nec seriatim punctatis, lateribus nullo 
modo explanatis, abdomine confuse crebrius punctato. Long. 32 m.m. 
Closely allied to B. protinoides, Sh. My specimen (which is a female) differs 
from the same sex of B. protinoides as follows:—It is a larger insect; the colour 
is much darker; the thorax is more transverse, with more strongly rounded sides, 
without the transverse impression near the base, with closer and confused punctua- 
tion (in B. protinoides it is very sparing and distinct; the sexes as in others of 
the genus being differently punctured), and the punctuation of the elytra does 
not run into lines. From B. olinde it differs in colour, in the total absence of 
strize from the elytra, and (probably) in respect of the sexual characters. 
The male is unknown to me. 
In the female the hind margin of the apical dorsal segment is rounded, and its 
extremity is narrowly reflexed. In the same sex of B. protinoides, the cor- 
responding segment has an obscure depression just before the hind margin, which 
is truncate. 
My single specimen of this insect was taken by beating flowers, at an elevation of about 3000 feet, 
on the Waianae Mountains, Oahu.

Brachypeplus. koelensis, n. sp.—Haud latus; convexiusculus; sat nitidus, 
parcius minus breviter pubescens; zeneo-niger, antennis, pedibus prothoracis ab- 
dominisque lateribus et maculis nonnullis per elytra dispositis, testaceis; capite 
prothoraceque crebrius fortiter punctatis; hoc vix transverso, antice vix angus- 
tato; elytris elongatis, obscure seriatim punctatis, interstitiis vix conspicue punc- 
tatis. Long. 3} m.m. 
Rather closely allied to B. protinoides, Sh., but incapable of being treated as a 
variety of that species, being a narrower, more convex insect, with the thorax less 
strongly transverse, and scarcely at all narrowed in front. The elytra are longer 
and more finely punctured, and the sexual character of the only sex known to me 
is quite different. 'The narrow convex form and comparatively elongate thorax 
will separate this insect from all the other species described in the same section of 
the genus. 
In the male the apical dorsal segment of the hind body is strongly, almost 
semicircularly, excavated behind, the sides of the excavation being produced in 
short, distinct, acute teeth (as in B. bidens, Sh.). 
The female is unknown to me. 
I am unable to understand Dr. Sharp’s ‘‘vix transverso,” as applied to the 
thorax of B. protinoides. In all my specimens the thorax is “‘fortius trans-
