186 REVISION OF THE GENUS PAROPSIS, 



ut 11 ad 5 latiori, in disco ut caput (ad latera grosse vix 



confluenter) punctulato, utrinque latera versus late profunde 



impresso, lateribus leviter bisinuatis, angulis posticis rotun- 



datis; elytris subfortiter minus crebre (quam /-*. irroratce, 



Chp., paullo magis fortiter, sat multo minus crebre) 



punctulatis, interstitiis nonnullis leviter verruciformibus ; 



prosterno inter coxas baud sulcato. Long. 4, lat. 3 lines. 



The non-sulcate prosternum separates this species from all 



others of the group except porosa, Er., with which it certainly 



does not seem allied in any other respect. Nor do I believe that 



the absence of the prosternal sulcus is a constant character. If 



I am right in this opinion, specimens in which the sulcus is 



present must be placed in my tabulation beside irrorata, Chp., 



(where the species seems much more at home). It is very distinct 



from irrorata by inter alia the less close and evidently stronger 



puncturation of its elytra, which on the front part of the sub- 



sutural region is very much less close.

Group ii. 



This small aggregate consists of species that agree in the 

 puncturation of their elytra beina' non-seriate and the lateral 

 outline of their prothorax non-sinuous, but whose great diversity 

 in respect of other characters shows them to be an accidental 

 assemblage of aberrant forms of Paro2)sis. Some of them are 

 among the least, others among the most, strongly convex species 

 of the genus ; some among the most brightly coloured, some 

 among the most obscure; some among the most, some among the 

 least, strongW sculptured. 



Twenty-eight names seem to be all that have been applied to 

 members of this group (/^ ^:»erp^ea^a, Chp., being excluded as I 

 have already— P. L.S.N S.W. 1897, p. 186— dealt with it as 

 having been wrongly referred hither by its author). Of these 

 only two appear to be synonyms (viz., Ati'opos, Stal, and biplagiata, 

 Bohem., apparently synonyms of itnmaculala, Marsh.). There 

 are seven species {suspiciosa, Baly, pedestris, Chp , glohata, Chp.,
