This makes the tenth species of the subgenus Acanthogeniits 

 characterized by M. Rciche in the 'Aunales de la Soc. Ent. de 

 France/ 1842, p. 334. 



Sisi/phus Boimngii. — A very striking species, at once distin- 

 guished by a long, slightly bent, bluntish 

 spine attached to the coxa of the hind-leg, 

 if it be not an elongation of the coxa itself; 

 it is equal to the femiu- in length. This spine 

 is slightly compressed, thickest at the base ; 

 about the middle it suddenly begins to be 

 attenuated to the end, which is somewhat flat- 

 tened and bent. 



Head in front slightly sinuated and notched on each side of 

 the clypeus. Thorax very convex, in front angled, the sides com- 

 pressed and ridged above, the surface above seemingly rough 

 mth short, somewhat distant bristly hairs, each proceeding from 

 a round smoothish spot. Elytra with seven longitudinal, smooth, 

 chain-like impressed lines on each ; two rows of distant short 

 bristles between each line. Anterior tibire with three strong bent 

 teeth on the outer edge. Femora of middle pair of legs with a 

 bluntish tooth on theinside near the base. Femora of hind-legs 

 most dilated a little beyond the middle ; tibife of same pair much 

 bent (a male) and slightly serrated inside near the end ; an ele- 

 vated subserrated ridge on each side ; the different ridges, espe- 

 cially those behind, furnished with reddish hairs. The whole 

 insect is of a shghtly greenish bronzed brown, the legs most clear. 

 Length to the end of body 5f lines.

I have much pleasure in naming this fine species after Mr. 

 Bowring, who promises to extend very much our acquaintance 

 with the insects of China. 



Onthophagus bifurcalis. — Head with a long flat ascending ap- 

 pendage proceeding from about the middle and deeply forked at 

 the end, \vith slightly diverging prongs, and when the head is 

 raised nearly approaching the thoracic projection, which at the 

 end is depressed, dilated and notched, the back of it grooved ; the 

 thorax behind has a very distinct dorsal gi-oove, in front, at the 

 base of the projection, bulging and not hollowed out as in O. 

 mergacenis, Hope ; thorax finely punctated and of a deep bro^^^l 

 with greenish and puii)lish reflections. Elytra of a yellowish 

 browm, ribbed, three of the costte somewhat elevated, the inter- 

 lineations punctate, in some specimens the dots scarcely visible ; 

 clypeus and legs pitchy bro^^Tl ; tibi« of fore-legs with four strong 

 teeth, the hind one obsolete ; femora of fore-legs margined with
