I have not seen an authentic type of this genus, but this 
species agrees well with Mr. Pascoe’s generic diagnosis, except in 
its rostrum being very evidently compressed at the base (possibly 
only in the female), which is a character not mentioned by Mr. 
Pascoe. The elytra of the present species are at their widest at 
the base, where they are about half again as wide as the base of 
the prothorax, and whence they are narrowed hindward.

OLANA. 
O. metropolitana, sp. nov. Ovalis ; ferruginea, antennarum clava et 
(versus apicem) tarsis infuscatis ; squamis concoloribus et non- 
nullis albidis vel albido-viridibus vestita ; his in prothorace 
trivittatim et in elytris ut vitte plurime abbreviate (vitta 
suturali magis conspicua magis continua) condensatis ; rostro 
(maris) quam prothorax fere sesquilongiori, sat cylindrico, 
leviter arcuato, punctulato, apicem versus fere levi; pro- 
thorace sat transverso, antice modice angustato, ad apicem 
transversim depresso, crebre minus fortiter ruguloso, lateri- 
bus leviter rotundatis; elytris punctulato-striatis, inter- 
stitiis sat planis punctulatis ; antennarum funiculi articulo 
2° quam 1"* multo breviori, quam 3° haud multo longiori. 
Long. (rostr. incl.), 2 1.; lat., 21 
The white or greenish scales on the elytra of this species form 
numerous short longitudinal lines, that on the suture being the 
most conspicuous and most continuous.

O. mentitrix, sp. nov. Ovalis; sat elongata; ferruginea, corpore 
subtus picescenti, nonnullorum exemplorum antennarum 
funiculo plus minusve infuscato; squamis albidis subtus 
dense equaliter, supra subvittatim, vestita; setis erectis 
albis et nonnullis nigris sat sparsim instructa ; rostro quam 
prothorax (maris parum, femine sat multo) longiori, leviter 
compresso, leviter arcuato, punctulato, longitudinaliter 
striolato, lateribus pone medium sulcos (his scrobes simu- 
lantibus) ferentibus ; prothorace vix transverso antice parum 
angustato, lateribus sat rotundatis; elytris punctulato- 
striatis, interstitiis sat planis punctulatis; antennarum 
funiculi articulis 1° 2° que elongatis, hoc quam illo sat 
breviori. Long. (rostr. incl.), 2 1.; lat., 4 1 
I refer this species to Olanca as having (in combination with 
the general eharacters of Xeda and its allies) rostral scrobes 
abruptly directed to the underside of the rostrum. Neverthe- 
less, it differs from the previously described Olanwe in having a 
lateral furrow on either side of the rostrum (not unlike that of 
Erytenna), which at the first glance might be mistaken for the
