belonging to the genus Melohasis Gory {Ahrohapta Dej.) 

 conclude the present number of our specimens. 



The number of the Elatericloe is not quite so limited as 

 that of the Bn/prestidoe ; their forms are little remarkable, 

 though in some respects peculiar. Among those with 

 f. antenna appears the universally distributed genus 

 Lacon. (*) : it is represented by two species, of which one 

 is new; the other, L. caliginosus, has been repeatedly 

 described (f), and, according to Guerin, is found also in 

 New South Wales, (Port Jackson) . Monoerejndiiis Esch., 

 a genus common both to New Holland and America (J), 

 affords six species, all of which are new, with one exception, 

 M. Australasia ( § ) Dej. A new species of the genus 

 Melanoxanthus 'Esoh. (||), whose type fEl.melanocejoJialusY.) 

 is distributed over the East Indies and Madagascar, and 

 of which Dej can mentions two more East India species, has 

 been sent from Van Diemen's Land : it will be described 

 below. Another remarkable new species presents all the 

 characteristics of the genus Pristilojohus Latr. (^). which 

 has been formed at the expense of Ludius Esch., although 

 this latter requires a yet closer definition of its Hmits. 

 Finally, there are two new genera to be mentioned, both 

 of which are probably pecuHar to New Holland : the one, 

 Crejpidomenus, presents great analogy to those forms which
