45. Xenocerus lateralis annulifer snl>sp. nov. 



(??. Fourth segment of auteniia of ? twice the length of the fifth, both 

 strougly compressed, eighth and iipperside of seventh white ; antenna of S bhxck. 

 Mesial vitta of pronotnm broad, lateral one vestigial. A wliite ring on each 

 elytrum from suture to shoulder, open in front, a transverse liand behind middle, 

 oblique on each elytrnm, jirodnced forward upon suture, reaching short basal sntnral 

 vitta or not ; no lateral vitta or only a vestige of it. Pygidium with two minute 

 white basal dots. Underside and legs black.

Two pairs. 



The half-ring at the base of each elytnim distinguishes this subspecies 

 abundantly from the Amboina form A'. Inf. Intrral/.^ (Is94) Jord., of which we 

 have now two SS and one ?. 



40. Xenocerus spilotus spec. nov. 



(J. Antenna as in variabilis (186L)) Pasc. Prothorax slenderer than in that 

 species, with three narrow white vittae, which are prolonged over the occiput; spots 

 of elytra grey, nearly all isolated : one at bnse above shoulder, an indistinct one 

 below shoulder, a larger one occupying basal fourth of suture, its basal half nearly 

 confined to the sutural interspace, its distal half expanded to tlie third line of 

 punctures, another sutural spot behind middle, also narrow in front and wide behind, 

 Isnt almost comjiletely sejiarated at the suture ; a halfmoon-shajied spot at lateral 

 margin at basal fourth, a subquadrangular one on disc before middle, a smaller spot 

 in the same interspace close to hinder edge of second sutural spot, a triangular spot 

 just before the second discal one, but more lateral, and a small spot before apex 

 between lines fi and 7. Pubescence of pygidium and underside grey ; pygidium 

 with narrow black mesial vitta.

47. Xenocerus russatus s])ec. nov. 



S ?. Similar to medinm-sined and small specimens of A', everetti (1894) Jord. ; 

 slenderer, the dark parts of the tomentum of the upperside more russet ; the lateral 

 carina of the prothora.x distinctly curved upwards in middle of thora.x : segments 

 2 to 5 of antenna of i with a dense fringe of short fine ciliae beneath.

A series. 



The small ovate groove present in the 6 of everetti at the apex of the second 

 antenual segment is found also in russatus c?. 



48. Xenocerus mamillatus spec. nov. 



?. Knfescent; tomentnm of upperside brown, of underside buft'. Three vittae 

 on head and pronotum, and the following markings on the elytra buff: a broad 

 sntnral vitta extending to a])ex, but restricted to the sutural interspace in apical 

 fourth, the sutural edge itself remaining of the ground-colour from near scutellum 

 to near declivous apex ; from this vitta branches off a broad and short streak which 

 ends at the tip of a rather prominent anteapical tubercle, and close to the vitta at
