captured. T send you short descriptive differences, whereby any one 

 can ascertain which species he possesses, and should any one be able 

 to give the locality of zonatus, and satisfactory evidence of its capture, 

 the question will be at once decided." 



Mr. O. Janson has a specimen from the late Mr. Chant's collection. 

 Gallicus, Muls., is a synonym of aldominalis, Menetr., and zonatus, 

 Schmidt, apparently another synonym. The continental zonatus, 

 Germ., being a separate species. 



Like the preceding species, I have heard of no recent captures, 

 and the matter seems to stand as Mr. F. Smith left it in the Zoologist, 

 for September, 1848. However, both R. ochraceus and T. aldominalis 

 are in all the British catalogues, viz., G. R. "Waterhouse, 1858, G. E. 

 Crotch, 1863, E. C. Eye, 18G6, David Sharp, 1871, F. P. Pascoe, 1882, 

 and Sharp's 2nd Edition, 1883, besides Matthews' and Eowler's.

 Robust, oblong, narrowed behind. Below greenish-black, closely 

 pubescent. Thorax, femora, and base of the tibise, fulvous. Elytra 

 metallic-green, deeply and closely punctate-striate, the interstices 

 sub-costate, finely punctured and wrinkled. Length, 4 lines. 



Sah. : Madagascar (Majunga). 



Head greenish-black, tlie sides strongly punctured, the middle with a longitu- 

 dinal groove, lower part of face covered with adpressed, whitish, long pubescence. 

 Eyes large, triangularly notched. Palpi, and the two or three basal joints of the 

 antennee fulvous, the latter extending slightly beyond the base of the elytra, their 

 third and the two following joints slender, sub-equal, the rest shorter, black, slightly 

 thickened. Thorax transverse, greatly narrowed and deflexed in front, the sides 

 nearly straight, posterior margin concave, its median lobe distinctly bidentate ; sur- 

 face extremely finely and closely punctured, the punctures slightly elongate, fulvous, 

 extreme posterior margin piceous, serrate throughout. Scutellum sub-quadrate, 

 black, punctured at the sides. Elytra not wider at the base than the thorax, dis- 

 tinctly narrowed behind, of a metallic greenish-bronze colour, each elytron with ten 

 regular rows of deep and closely placed punctures, which, at the posterior portion, 

 are transversely aciculate or wrinkled, the interstices very closely and finely punc- 

 tured, obsoletely raised, more distinctly convex at the sides. The apex of each 

 elytron slightly produced in a rounded point. Legs robust, fulvous, the apex of the 

 tibise and the tarsi black. Prosternum broad, square-shaped. Last abdominal 

 segment with a deep transverse fovea. Pygidium broadly truncate at its apex.
