Leptops dorsatus. L. obovatus, niger, dorso fuligineo-, lateribus 

 cinereo-squamulosus; rostro in medio longitudinaliter elevato, utrinque 

 basi breviter sulcato ; prothorace rugoso, in medio leviter excavato, 

 lateraliter parura rotundato ; scutello parvo, subtriangulari ; elytris 

 ampliatis, breviter ovatis ( 5 )> singulatim triseriatim tuberculatis, tu- 

 berculis posticis sensim majoribus, serie externa excepta, hscc me- 

 diana, trituberculata ; infra pedibusque parce griseo-squamulosis, pilis 

 remote interjectis. Long. 5 lin. 

 Hab. West Australia. 



In appearance almost exactly like L. spinosus, but it is not 

 tomeutose as in that species ; the dark smoky stripe on the 

 middle of the prothorax and between the inner row of tubercles 

 on each elytron will at once differentiate it. 



Leptops acerbus. L. obovatus, niger, sat parce griseo-squamulosus ; 

 rostro quinquecarinato, interstitiis excavatis ; prothorace utrinque bi- 

 carinato, carina exteriore prominente, rotundata, dorso late et i)ro- 

 fundc excavato, lateribus rugoso, subtuberculato, basi constricto ; 

 scutello oblongo, dense squamuloso; elytris ampliatis, breviter ova- 

 tis ( $ ), singulatim triseriatim spinosis, seriebus posticc approxi- 

 mantibus, spinis apice denudatis, nitidis, interstitiis biseriatim foveo- 

 latis ; corpore infra, pedibusque griseo-squamulosis, squamis angu- 

 stioribus et majoribus intermixtis. Long. 8 lin. 

 Hab. Western Australia. 



Allied to L. spinipennis ; it is the only species known to me, 

 except L. Duhoulayi, in which the rows of spines gradually ap- 

 proximate posteriorly, instead of diverging, or being at least 

 nearly parallel. 



Leptops polyacanthus. L. obovatus, niger, squamosit te terrea 

 indutus ; rostro quinquecarinato ; scrobe flexuosa, ad oculura fere de- 

 sinente, inter oculos tuberculis duobus manifeste elevatis; prothorace 

 rotundato, in medio late sulcato, confertim et fortiter granulato ; 

 scutello occulto; elytris breviter ovatis, singulatim quadriseriatim 

 tuberculatis, serie suturali duobus posticis validis, serie externa tu- 

 berculis quatuor lateralibus, quorum primo magno, seriebus inter- 

 mediis tuberculis posticis majoribus, apicibus, paulo productis; infra 

 pedibusque griseo-squamulosis, his setis nigris interjectis. Long. 

 5i-6 lin. 

 Hab. Australia. 



This species and the following are the only two members of 

 Leptops which have tubercles between the eyes ; the two tuber- 

 cles in this species are well elevated, with a rounded outline, and 

 placed each at a little distance from the eye, the two lateral 

 carinte commencing directly beneath.
