straight from near the median part to the base ; it is finely and 

 moderately closely punctm^ed, not marginate along the base, the 

 two basal impressions are deep and more or less slanting towards 

 one another, and there is a faintly raised smooth line reaching in 

 the middle from the apex to the median part, and from there a 

 short, impressed line ; scutellum short, distinct, triangular ; elytra 

 shaped as in 0. aygiiliis, but a little less deeply emarginate laterally; 

 pygidium a little convex, not deeply punctured ; metasternum not 

 grooved. 



Male : Clypeus slightly emarginate in front ; anterior tibiae not 

 very falciform, the apical mucro more or less sharply incurved, 

 quadri-dentate outwardly, and having underneath three long, vertical 

 teeth the basal of which is more or less bifid ; in some examples 

 there are only two teeth ; femora with only one strong, slanting, 

 long tooth on the upper margin, at about the median part, this 

 spine projects above the tibiae when the latter is closed; inter- 

 mediate femora with a sharp, even carina, intermediate tibiae 

 simple ; posterior femora with a long, slanting, sharp tooth on 

 the lower margin. 



Female : Clypeus aculeate, tubercle on the vertex not more 

 developed than in the male. 



Length 14:-|-17J mm. ; width 8J-10 mm. 



Apart from the colouring of the prothorax, this insect differs from 

 0. sphinx in the shape of the prothorax, which is longer and more 

 parallel, the armature of the under side of the fore tibicB is different, 

 and the tooth on the lower margin of the posterior femora is longer 

 and sharper, the anterior femora have only one long tooth on the 

 upper margin, and none on the lower.

Bronze with a greenish tinge, slightly rufescent on the elytra ;

 carina short, equi-distant from apex and base, frontal carina broadly

 part of the frontal carina, basal carina hardly noticeable in the 

 central part, the clypeus is rugose or plicate according to the sex,
