again as the base of the prothorax, spotted with tufts of short 

 dark brown hairs, towards the apex a transverse, whitish, irre- 

 gular, somewhat zigzag band ; antennaj pubescent, the first 

 joint black. 



Nearly allied to M. granuUcolUs from the Aru Islands, but 

 larger and proportionally more robust, the band on the elytra 

 transverse, not oblique, and with the peculiar little gibbosity 

 on the prothorax. 



Agelasta mediifusca. 



A. grisescens, fusco-variegata ; antennis annulatis ; elytris, basi 

 apiceque exceptis, fuscis, maculis plurimis dispersis ; tibiis an- 

 ticis apicem versus incrassatis, extus pilosis. Long. 6 lin. 



Hob. Andaman Isles. 



Quite unlike any other Agelasta^ but with the anterior tibia? 

 •thickened and fringed with short hairs as in A. callizona. 

 Pubescence greyish varied with brown ; on the head and pro- 

 thorax the brown occurs in confluent spots, the middle of the 

 latter being somewhat bare of pubescence ; on the elytra the 

 brown forms a broad band finely speckled with grey ; the tips 

 of the tibige and first two joints of the tarsi are black ; under- 

 part irregularly greyish ; antennce about the length of the 

 body, the basal joint spotted, the second entirely greyish, and 

 the third and sixth greyish only at the base, the rest dark 

 brown inclining to black. 



Peribasis princeps. 



P. obovatus, uiger ; prothorace sparse fulvo-pubescente ; elytria 

 pube interrupta Isete aeruginosis, regione scutellari maculis fulvis.

Hah. Labuan. 



Obovate, black ; head with five determinate patches of ful- 

 vous pile, viz. two frontal, one on each cheek, and one on the 

 vertex ; antenna black, about as long as the body in the 

 female ; prothorax speckled with fulvous, the lateral spine 

 small ; scutellum fulvous ; elytra with a projecting lobe at 

 the base on each side of the scutellum, the sutural region with 

 fulvous spots, the sides rich bluish green, more or less speckled 

 with black ; underparts and femora with a rather dense 

 fulvous pile, except the middle of the abdominal segments ; 

 tibijB and tarsi with a sparse whitish pubescence. 



This handsome species differs structurally from its conge- 

 ners in the lobed base of the elytra, as in Otarionomus ; in 

 other respects it is a true Peribasis. I have seen no males ; 

 their antenna? will probably be twice the length of the body.
