400 Mr. A. M. Lea's Notes on 



Hob. N. W. Australia (types in Macleay Museum). 



In the type a small spot at the apex of each elytron is 

 pallid, in a second specimen these spots are present and 

 there is as well a very distinct pallid transverse triangle 

 (common to both) with its base about one-fourth from the 

 base and its apex just beyond the middle. The elytral 

 punctures are nowhere small though smaller posteriorly. 



Differs from Cr. cruditus, Baly, in having the head 

 strigose at sides, and the prothoracic margins much wider ; 

 the scutellum is also of different shape and the base is 

 much more feebly notched. From Cr. iridipcnnis, Clip., it 

 differs in its shorter and thinner antennae and the elytra 

 differently punctured and with smaller subhumeral lobes. 



Cryptocephalus melanopus, n. sp. 



(Plate XXIV, fig. 125.) 



9 . Almost flavous ; head (montli parts in places obscure reddish), 

 antennae, extreme base and three spots on prothorax, scutellum, 

 metasternum, middle of base of abdomen (intercoxal process 

 excepted), and legs (coxae excepted) black ; elytra with two metallic 

 green fasciae. Head, pygidium, and under-surface with rather long 

 whitish pubescence. 



Head densely punctate, the punctures partially concealed by 

 clothing. Antennte rather short, second joint about half the length 

 of third, third slightly shorter than fifth. Prothorax scarcely twice 

 as wide as long ; with moderately dense and comparatively small 

 punctures, smaller on disc (which is gibbous in front) than else- 

 where ; oblique impressions feeble ; margins narrow. Scutellum 

 subtriangular, longer than wide, apex truncate, base entire. Elytra 

 suboblong, subhumeral lobes small ; densely but not coarsely 

 punctate, punctures becoming smaller and seriate in arrangement 

 posteriorly. Apex of prosternum wide and feebly bilobed. Ab- 

 domen with the fourth segment largely encroached upon by fovea ; 

 the latter with feeble lateral extensions. 



Length 5 mm. 



ITah. N. W. Australia (type in Macleay Museum). 



The elytral fasciae do not touch the sides, the basal one 

 is advanced along the suture and on the shoulders, so that 

 its apical edges are concave ; the second fascia is at about 

 the apical third and narrows towards the suture. In 

 colour to a certain extent it resembles some of the varieties of 

 Gr. parentheticus, Sufifr., but the punctures both of prothorax 

 and elytra are very different to those of that species.
