basal joints of the antenrice beiieatli, the palpi (except at 

 the tip), the trochanters, the femora at the base or beneath, 

 the intermediate tibiae within, and the abdomen in part, 

 testaceous ; clothed with wliitish hairs intermixed witli long, 

 erect, blackish setse. Head densely puuctulate and trans- 

 versely depressed anteriorly, much smoother at the base ; 

 antennae long, slender. Pi'othorax nearly as long as broad, 

 sparsely punctate on the disc, rugulose at the sides. 

 Elytra densely, rugulosely punctured. Anterior tibise 

 abruptly, subarcuately dilated and compressed in their 

 apical third ; anterior tarsal joints 1 and 2 stout, 2 ex- 

 tending over 3; intermediate tibise (PI. VIII. fig. 12) curved, 

 enormously tliickened, rounded and convex externally, 

 abruptly narrowed at the apex, very deeply excavate within 

 and deeply sinuato-sulcate along the median third above, 

 the up[)er inner edge armed at the middle with a stout, 

 compressed, forwardly-directed, acute iiook, and the lower 

 inner edge arcuately lamellate opposite this.

One male. Very near the insect here identified as 

 H. specAabilis, Ancey, but readily distinguished from the S 

 of that si)ecies by the stout, chitinous hook at the middle of 

 the inner edge of the intermediate tibise, the corresponding 

 appendage being formed by a tuft of matted hairs in 

 H. elgonensis, ahyssinicus, and comtrictipes, and by a thin 

 ciliated lamella in H. malachioides. 



18. Hapalochrus bilamellatus, sp. n. 

 (^ . Elongate, robust, shining ; golden-, brassy-, or bluish- 

 green, the elytra sometimes suffused with cyaneous at the 

 base or sides, the labrum, the basal joint of the antennae on 

 its outer edge, the intermediate tibite on its inner aspect 

 from the middle to the apex, and the abdomen in part, 

 testaceous ; clothed with whitish pubescence intermixed 

 with numerous long, erect hairs. Head densely punctulate 

 and transversely depressed anteriorly, smoother at the base ; 

 antennae moderately long, rather strongly serrate from the 

 fifth joint onward. Prothorax transverse, sparsely punctu- 

 late. Elytra much widened posteriorly, bluntly rounded at 

 the apex, densely, finely, rugulosely punctate. Anterior tibite 

 slightly liollowed at about tlic middle within ; anterior tarsal 

 joint 2 much longer than 1, thickened and pectinate at tip ; 

 intermediate tibiae (PI. VIII. fig. 13) swollen, strongly 

 curved, convex externally, deeplv excavate on their inner
