MESETIA (gen. nov. brenthidarwi). 
Mas. Caput fere ut /thystena sed paullo minus elongatum ; ros- 
trum leviter compressum quam prothorax pzullo longius, 
supra longitudinaliter sulcatum ad apicem minus dilatatum ; 
antenne fere ut Jthysteni sed paullo breviores ; prothorax et 
elytra fere ut /thystena sed his (speciei typice) sat fortiter 
striatis ; femora postica vix ultra abdominis segmentum 2" 
extensa ; tarsorum posticorum articulus 1"* quam sequentes 
2 conjuncti haud longior; abdominis segmenta basalia 2 
longitudinaliter concava. 
Femina latet. 
In M. Lacordaire’s arrangement of the Brenthide this genus 
is referable without hesitation to the division consisting of the 
two groups Lelorhynchides and Ithystenides (which are dis- 
tinguished inter se by the tarsi either ‘robust, with the basal 
joint not longer than the next two together” or “slender, with 
the basal joint longer”) but it seems to be intermediate between 
those groups, having slender tarsi the basal joint of which does 
not exceed the next two in length. I cannot find that it has 
been hitherto characterised. 
M. amena, sp. nov. Rufo-testacea ; capite antennis prothoracis 
vittis 3 pedibus elytrorum parte suturali et corporis subtus 
partibus lateralibus nigro-piceis, elytrorum vittis discoidali- 
bus 3 angustis flavo-testaceis ; capite prothoraceque fere 
leevibus ; elytris leviter striatis, striis crebre minus fortiter 
punctulatis. Long. (rostro excepto), 8 |.; lat., 1,4, 1.

LONGICORNES. 
OPSIDOTA. 
O. estuosa, sp. nov. Mas. Rufa, pilis albis sat sparsim vestita, 
his in prothoracis basi maculis 3 et in scutello condensatis ; 
sat grosse (elytrorum apicem versus vix rugulose) ruguloso- 
punctulata ; antennis quam corpus vix longioribus, articulis 
(basalibus 2 exceptis) fortiter compressis, 3° quam 4° sub- 
breviori, 11° appendiculato ; prothorace quam longiori fere 
sesquilatiori, ante medium rotundato-dilatato, in disco longi- 
tudinaliter breviter elevato-glabro ; elytrorum apice suturali 
spiniformi. Long., 15.1.; lat., 42 1. 
Femine antennis quam corpus multo brevioribus, oculis quam 
maris inter se minus approximatis. Long., 18 1.; lat., 51. 
Sculptured almost exactly as Anatisis laminosus, Newm., but 
a little more coarsely on the basal part of the elytra. Also bears 
considerable resemblance to A. /renchi, Blackb., but at once 
distinguishable by its male having non-flabellate antenne.
