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



the first are red ; in this specimen also the elytral punctures 

 are larger and sparser than in other males under examina- 

 tion. I have a pair taken in copula in which the elytral 

 punctures are very different inter se. 



Two specimens before me from the Swan River at first 

 sight appear to be very distinct from Bynoei, but I am 

 satisfied they are varieties only ; in one of them the elytral 

 punctures are as in the ordinary female, but the black 

 markings of the upper surface (including the head) consist 

 of a narrow edging common to the prothorax, scutellum, 

 and elytra, but on the latter continued to form a humeral 

 spot (elevated and tuberculiform as in all other specimens 

 of the species), and two disconnected postmedian spots 

 placed as in Cadmtis excrementao'ius, Sutf. ; the antennae 

 are black, but with the three basal joints more or less 

 obscurely diluted with red ; the apex of the tibise and the 

 tarsi are black ; the metasternura is very slightly infuscate ; 

 the other specimen agrees in its markings with this one 

 except that the postmedian spots are slightly larger, and 

 that all the appendages are pallid ; its punctures, however, 

 are very much coarser (much coarser than on any other 

 specimen I have seen) both on the prothorax and elytra ; * 

 in both these specimens the shape and proportions of the 

 antennae joints, the scutellum rounded behind with an 

 unusually large basal fovea, are as in ordinary specimens. 

 At first sight it would appear almost absurd to associate 

 this specimen with typical ones of Bpioei, but I am 

 convinced that it can only be regarded as a variety of that 

 species. 



The species has been re-described by Chapuis under 

 the name of Cryptocephalus convexicollis, from quite 

 ordinary specimens. Chapuis records it from Brisbane, 

 Rockhampton, and Swan River ; I have only seen specimens 

 from Western Australia. 



Idiocephala cyanipennis, Saund. 

 var. Cryptoceiohalus condensatus, Suff. 



(Plates XXV, XXVI, figs. 161, 188.) 



Mr. Saunders described this species (giving the locality 



as " New Holland ") as having '* under-side of body pale 



ochreous yellow " ; subsequently Chapuis described it as a 



Cryptocephalus, and as having " metasterno vix infuscato." 



* These might quite fairly even be called foveate-punctate.
