projection is strong and sharp.

Minus brevis ; subparallelus ; fusco-ferrugineus, pedibus parum 
dilutioribus, albido squamoso-setulosus, setulis in elytris fasciam 
postmedianam formantibus ; rostro sat elongato apice minus 
dilatato, in medio carinato ; capite inter oculos canaliculato, 
prothorace quam longiori quinta parte (quam margo anterior plus 
dimidio) latiori, crasse confuse rugoso, disco depresso in medio 
fortiter carinato ; scutello minus elongato, elevato ; elytris a basi 
postice leviter angustatis, sat convexis, fortiter cancellato-punctu- 
latis (interstitiis sat rugulosis), antice bituberculatis, interstitio 3®

Much less strongly narrowed behind than is usual in the 
genus. In fresh specimens the hair-like white scales are con- 
densed upon the rostrum and the middle of the prothorax, on the 
scutellum, and especially on the elytra behind the middle, where 
they form a fascia very similar to that of 0. fasciatus, Boisd. 
The sides of the prothorax are almost parallel from the base to 
the middle, where they are rounded, and whence they converge 
towards the front. The base of each elytron is tumid from the 
humeral angle to near the scutellum, the extremities of the tumid 
region being more elevated than the rest (thus forming the two 
basal tubercles) ; the interstice on which the inner basal tubercle 
is situated is strongly carinate from a little before to a little 
behind the beginning of the apical declivity (thus forming the 
post median callosity), and several of the external interstices 
become somewhat cai'inate towards the apex, which consequently 
has a somewhat undefinedly uneven appearance. 
The sculpture and markings of the elytra have a general 
resemblance to those of 0. fasciatus, Boisd., compared with which 
this insect is of a different colour and much narrower and more
