A female from Kuranda in M. Hackers' collection has the elytra 

 more rounded than usual, and with only two rows of tubercles, 

 except that the outer row is represented by a single acute spine 

 on the shoulder, the other tubercles are also more acute than usual 

 of rather less numerous. 



Leptops nodicollis Lea. 



In perfectly fresh spécimens of this species the médian carina of 

 the rostrum is usually quite concealed by the clothing, so that the 

 middle appears to be grooved (1). The size varies from 9 to 20 mill. 

 The scales (apart from the setœ, which are also variable in colour) 

 also vary from almost white to dark ochreous, and frequently the 

 apical half of the elytra is darker than elsewhere. On several 

 spécimens there is a broad band of obscure white at sides of elytra. 



Hab. : Queensland : Kuranda, Cooktown, Cairns. 



Leptops horridus Lea. 



On several spécimens of this species the scales hâve a golden or 

 silvery gloss, except on the dark abdominal patch. 

 Hab. : Queensland : Cairns, Gloncurry. 



Leptops brachystylus Lea. 



On several spécimens the subsutural row consists of five dorsal 

 tubercles instead of four. On one there is a line of brilliant green 

 scales at the base of the head and somewhat similar scales along the 

 suture; on both prothorax et elytra of this spécimen the scales 

 hâve a soft golden lustre. 



Hab. : Queensland : Kuranda; N. W. Australia : King's Sound. 



Leptops tribulus Fab. 



This is the most common and variable species of the genus; 

 ranging in length from 14 to 30 mill. The maie is usually much 

 smaller and narrower than the female, and with more prominent 

 tubercles; its scutellum is also longer. 



The tips of the ocular lobes are nearly always diluted with red. 

 The clothing is usually of a muddy grey and appears to be easily 

 abraded ; frequently it is paler on the scutellum than elsewhere.
