line, black, slightly virescent on the back, but bright metallic 

 bluish-green on the anterior angles and sides, which are mar- 

 gined ; smooth, shining, and with a few leather large punctures 

 scattered sparingly and irregularly over the surface, a little more 

 frequently towards the base; a deep, impunctate, longitudinal 

 fovea is placed a little in advance of the base on each side of 

 the dorsal line, but nearer to the external margin than to the 

 latter. Scutellum subsinuate-triangular, impunctate, with a 

 slight depression on each side towards the base. Elytra gla- 

 brous, long, broad and depressed, black, with a very slight 

 bluish-green tinge at the base and margins, punctate-striate, 

 the stride deep, but the punctures in them rather faint and 

 transverse; the interstices convex and impunctate; the mar- 

 ginal space pubescent, finely punctate, with a few larger de- 

 pressions ; remains of pubescence are also seen springing from 

 the punctures in the strise; the apex is only slightly emarginate. 

 Under side piceous ; prosternum smooth, with a few scattered 

 punctures on the sides ; mesosternum more so, and metasternum, 

 episterna, and abdominal segments with a fine granular or 

 papillose punctuation, most marked on the sides. Legs ru- 

 fescent, with the knees and tarsi somewhat darker. 



I have named this fine species (the largest of the Chlcenii 

 which I have received from Old Calabar) after the Rev. Hope 

 M. Waddell, one of the most zealous and able of the mission- 

 aries who have done so much both for natural science, civiliza- 

 tion and religion in this interesting region.

This beautiful insect, when in good preservation, is readily 

 recognized by the alternate interstices shining with a metallic 

 lustre. It, however, sometimes arrives in a rubbed or greasy 

 state, when the metallic lustre is almost entirely effaced from 

 the interstices.
