546 Mr. Francis P. Pascoe's Notes on 



Genus Mycekinus. 

 1. Mycerinus luctiiosus. (PI. XXII. fig. 5.) 



M. dense tomentosus, niger, maculis albis ornatus ; capite 

 prothoraci latitudine eequali. 



Port Denison. 



Covered with a short thick black pile, varied with rather large 

 white spots or stripes j head as wide as the prothorax, a white 

 line over the eye and a white spot on the vertex ; antennae shorter 

 than the body, the apex and base of each joint except the first 

 two, and the third joint, nearly entirely white ; prothorax nearly 

 quadrate, about equal in length and breadth, a stripe at the side 

 and two interrupted stripes on the disk white ; scutellum rounded 

 behind ; elytra convex and nearly parallel to the apex, which is 

 somewhat pointed, each marked with about ten white spots 3 body 

 beneath and legs with a dull greyish-white pubescence. 



Length 5 lines. 



In colour this insect resembles Mycerinus zehnnus, an Indian 

 species, but it is more cylindrical in form, with fewer and rounder 

 spots. 



2. Mycerinus uniformis. 



M. ferrugineus, fulvescente-pubescens ; elytris paullo elongatis, 

 sub-depressis, basi sparse punctatis. 



Port Denison. 



Ferruginous, closely covered with a pale fulvous pubescence ; 

 head concave in front, with a slightly impressed line on the vertex ; 

 antennse longer than the body, slender, setaceous ; prothorax 

 about equal in length and breadth, narrower anteriorly, rounded 

 at the sides, with a few punctures at the base ; scutellum trans- 

 verse, smooth in the middle; elytra rather elongate, somewhat 

 depressed, gradually narrower from the shoulder to the apex, 

 which is rounded, the base with a few small punctures ; body 

 beneath and legs with a thinner and paler pubescence. 



Length 5 lines. 



Closely allied to Mycerinus aridns, but different in colour, and 

 more slender in its proportions generally. Nevertheless it may 

 be only a local variety. 



Genus Ropica. 

 1. Ropica incivilis. 

 R. obscure griseo-pubescens ; elytris fere obsolete albo-macu- 



latis, apice obtuso-angulatis. 

 Port Denison. 

 With a short dull greyish pubescence ; head with a few coarse
