Hab. Queensland. 



This species belongs to the section represented byZ. quadri- 

 tuberculatus and allied forms. Its diagnostic characters will 

 be found in the form of the scape, combined with those of the 

 rostrum, scrobes, and the absence of tubercles on the elytra, 

 except at the shoulders and the four at the posterior part. In 

 the freshest of my specimens the scales have a very decidedly 

 pearly lustre. Curculio clavus, Fab. (unknown to Schonherr, 

 but referred to by him as probably congeneric with Hippo- 

 rhinus, and so placed in the Munich Catalogue), is a Leptops, 

 and belongs to this section. L. Hopei, Fahr., seems to me to 

 be identical with L. squalidus; indeed Fahrasus himself queries 

 "An femina Leptopis squalidi?" 



Leptops musimon. 



L. ovatus, fuscus, opacus, sat dense umbrino-squamosus ; rostro 

 crasso, antice profunde flexuoso-sulcato, supra oculum tuberculo 



• valido munito ; scrobibus brevibus, subtransversis ; antennis 

 robustis ; clava brevi, funiculo haud crassiore ; prothorace trans- 

 verso, basi quam apice paulo latiore, supra vermicidato-sulcato ; 

 scutello transverso, apice late rotundato ; elytris ovalibus, singulis 

 quadriseriatim tubercidatis, serie suturali tuberculis minoribus 

 antice obsoletis, serie externa tuberculis tribus, seriebus inter- 

 mediis sequalibus, singulatim sextuberculatis, interstitiis impresso- 

 punctatis, haud granulatis ; corpore infra pedibusque dense squa- 

 mulosis, parce griseo-setulosis. Long. 7 lin. 



Hab. Rockhampton. 



In L. polyacanthus and L. ebeninus there are also interocular 

 tubercles. The latter is a glossy black species with granules 

 on the elytra as well as tubercles ; the former has the rostrum 

 longitudinally grooved, the interspaces forming five carinae, 

 and the scrobe is longer and not transverse.
