242 Mr. F. P. Pascoe's Descriptions of New Genera 



Arrhenotus. 



Head small ; eyes deeply divided ; antennae distinct, slender, 

 longer than the body, first joint shorter than the third, the fourth 

 longest, the rest gradually diminishing ; prothorax transverse, wider 

 anteriorly {$) than the elytra, flat, almost concave above ; elytra 

 depressed, elongate, slightly tapering towards the apex ; legs 

 slender, of moderate length ; mesosternum produced, prosternum 

 notched for its reception. 



With very much the habit of Coptomma, this genus differs in the 

 eyes, prosternum and other characters ; from Tmesisternus and 

 allied genera, it may be distinguished by its more feebly developed 

 legs and antennae, &'c. It is geographically interesting as being, 

 so far as we know at present, the most western representative, 

 unless we include Leptocera, of a sub- family confined to New 

 Zealand, New Guinea and the more eastern islands of the Indian 

 ocean. 



Arrhenotus Wallacei. (PI. XXV, fig. 1.) 



A. niger, nitidus, punctatus ; capite prothoraceque vittis latis 

 quatuor elytrisque guttis numerosis aureis, apice elytrorum 

 bimucronatis. Macassar. 



Black, shining, smooth, four broad stripes on the head and 

 prothorax, and numerous spots on the elytra, formed by short 

 golden yellow hairs ; antennae and legs pale brown ; under surface 

 with a whitish pubescence; elytra bimucronate ; eye rounded 

 above anteriorly. 



Length 71 lines. 



Phacellocera Batesii. 



P. nigra, parce flavescente-pubescens, subtus plumbea ; anten- 

 nis longis, articulo tertio albo-annulato, apice nodoso ; elytris 

 integris. Para. 



Black, with a sparse pale yellowish pubescence, beneath plum- 

 beous ; elytra rather short, entire, punctate at the base, the 

 pubescence here and there absent, giving them a mottled appear- 

 ance ; antennae rather long, the third joint nodose at the apex, with 

 a white ring below it. 



Length, 6 lines. 



I dedicate this species to Mr. Bates, to whose extensive researches 

 and accurate observations in the valley of the Amazons, extend-
