with the elytra (except along the suture), the femora and tibife 

 lighter in colour than the rest ot" the body. 



The shape is moderately elongated, the female more oval and 

 compact than the mule. The liead is rather short, rugoselj 

 punctured, with a smooth median carina (which is sharply elevated 

 and free in front in the female only). The chjpens is rather broader 

 than it is long, with the margins curvilinear and strongly reflexed 

 and the front edge broadly elevated in the middle. The pro- 

 thorax is rather short, narrox^ed in front in the male, and approx- 

 imately semicircular in the female, with the sides sinuated beyond 

 the middle and the disc rather strongly punctured all over. The 

 scutellum bears a few punctures and the elytra are rather coarsely 

 punctnred, with two costae indicated upon the disc of each and the 

 external margins rugose posteriorly. The piigidium is rugosely 

 granular and hairy and bears a broad shallow impression on each 

 side. The mctastermim is coarsely punctured and clothed with 

 yellow hair except in the middle, and the abdomen is very smooth. 

 The sternal j'rocess is not very long and tapers to a point. 



The two sexes differ considerably in appearance. The male is 

 more elongate, more shining, and frequently of a brighter colour 

 than the female, and in addition to the different form of the head, 

 prothorax and front tibiae, the legs and the club of the antenna 

 are more slender. The abdomen is not channelled beneath.

Deep iiidigo-blue, with the outer margins of the elytra and 

 the three costa^ upon each more or less obscurely reddish. 



The body is depressed and rather elongate. The head is 

 sparingly ])unctured, the clypeus strongly excavated, bilobed in 

 front and broader than it is long, with its sides strongly curved, 

 and the forehead armed with a narro\\' carina strongly lobed 

 in front, the lobe extending to about the middle of the clypeus 

 and sharply pointed at the end. The prothora.v is distinctly 

 and evenly punctured all over, with its sides gently sinuated and 

 moderately contracted in front. The scntelluni is distinctly punc- 

 tured, and the elytra are decorated with large annular punctures 

 closely set in double rows, leaving three well-marked costsB 

 upon each elytron. The outer edges are gently sinuated and the 

 apical margins shining, but with coarse transverse punctures. 

 The pygidium is slightly rugose, the sides of the metastenmm 

 coarsely punctured and the abdomen moderately punctured. The 

 sternal j^rocess is slender, curved and pointed.
