new Species of Histeride. 369 
has a circle of punctures, punctures largest on each side; the 
pygidium, the upper portion is smooth in ¢, with a trans- 
verse band of punctures before the apex, in 2 the punctures 
are more scattered and the smooth upper portion less defined ; 
the prosternum is broad and widened out at the base; the 
mesosternum is laterally margined on the anterior portion 
only ; the anterior tibiew are 4-dentate. 
In the specific sequence this insect may be placed next to 
HI, Truxillana, Mars. 
Hab.’ Valley of the Rio Pardo, Sao Paulo, Brazil (£Z. 
Gounelle). 
Hololepta canaliculata, sp. n. 
Ovalis, subparallela, parum depressa, nigra, nitida; fronte trans- 
versa, labro brevissimo ; thorace post angulos conspicue canalicu- 
lato ; elytris striis 1-2 brevibus, 2 appendiculata; pygidio dense 
punctato, apice anguste levi; tiblis anticis obtuse dentatis. 
L. 94 mill. (absque mandibulis). 
Oval, rather parallel at the sides, somewhat depressed, 
black and shining; the head transverse and similar to that 
of H. excisa, Mars., without strie, labrum transverse and 
very narrow and anteriorly sinuous; the thorax impunctate, 
with the marginal striz widening out anteriorly into a deep 
furrow, the furrow is deepest in front and abruptly terminates 
before the anterior angle, the angle in @ is feebly emarginate, 
similar in this respect to /7. vulpes, Mars., anterior edge seen 
to be very feebly sinuous when viewed vertically ; the elytra, 
humeral sulcus is shortened at both ends, dorsal striz, 1 basal 
and short, 2 half the length of the first at the base, but with 
an appendage four times its own length; the propygidium is 
somewhat widely but sparsely punctured at the sides, the 
punctures are small and circular; the pygidium has similar 
punctures, but they are densely set with a narrow smooth 
apical margin; the menton is smooth and concave, with a 
small fovea on the posterior point of the concavity ; the pro- 
sternum widens triangularly at the base; the mesosternum is 
striate on either side; the anterior tibiz are very obtuse and 
the two apical teeth have a common base. 
In outline this species resembles H. menadia, Mars., but 
the thoracic furrow agrees with H. canalicollis, Lew., except 
that it is deeper and is shortened before the anterior angle. 
Hab. Paramba, alt. 3500 feet (Rosenberg). One male.
