BY THE REV. T. BLACKBURN. 289 



This species falls into the small group of Lacon which T 

 tabulated in P.L.S.N.S.W., 1891, pp. 508 and 509. In that 

 tabulation it stands beside L. lacrymosus, Cand., from which it 

 differs in its elytral costte not being tuberculate behind. It is 

 perhaps near L. granulatus, Macl., but hite?- alia the prothorax of 

 that species is said to be " much longer than its width." 



N. S. Wales ; taken by Mr. Musson near Xarrabri. 



Lacon squalescens, sp.nov. 



Minus opacus ; piceus, antennis pedibusque ferrugineis ; squamis 



pallide f ulvis sat dense vestitus ; capite prothoraceque fortiter 



minus confertim punctulatis ; illo depresso postice sulcato ; 



hoc fortiter convexo subgibbo, haud canaliculato, quam 



longiori paullo latiori, postice quam antice plus quam dimidio 



latiori, latitudine majori ante medium posita, lateribus antice 



sat rotundatis postice fere parallelis crenulatis, angulis anticis 



fortiter productis posticis oblique truncatis ; elytris basi fere 



rectis, quam prothorax vix latioribus plus quam duplo longi- 



oribus, modice convexis, punctulato-striatis, interstitiis trans- 



versim rugulosis inter se sequalibus, angulis humeralibus 



oblique truncatis ; sulcis tarsorum in prosterno sat distincte 



impressis, in metasterno fere nuUis. [Long. 5, lat. li lines. 



The very conspicuous pale fulvous scales clothing the upper 



surface, together with the shape of the prothorax, which is at its 



widest very little behind the front, render this a very distinct 



species. In Dr. Candeze's tabulation of the genus [Mem. Liege (2) 



iv.] it falls beside L. humilis, Er., a very different species.
