Australian and Tasmanian Cryptocephalides. 365 



Cryptocephalus VIRIDINITENS, Chp. 



A beautiful species in colour resembling jachsoni * but 

 in sculpture approaching scahvsus ; the narrow but distinct 

 carina on the pygidium should alone render it distinct. 



A male specimen (kindly presented to me by Mr. H. J. 

 Carter) has the prothorax and elytra of a beautiful golden- 

 purple, the base of the head and scutellum coppery or 

 coppery-green, the head in front, pygidium and the lower 

 surface green, the legs blue with purplish reflections and 

 the antennae black with, in places, a bluish gloss. In size 

 it is smaller than the female with the eyes closer together 

 and the antennae longer than the body (in the female the 

 antennae barely extend to the pygidium).

Cryptocephalus eumolpus, Chp. 

 (Plates XXII, XXV, figs. 28, 29, 145.) 



I have seen typical specimens of this species from 

 Mackay, Port Denison and Somerset. A variety from 

 Somerset differs in having the prothoracic marking 

 reduced to a narrow streak, the scutellum and elytra very 

 narrowly bordered with black, and the only spot on each 

 elytron the humeral one and this is deep black, without the 

 least bluish or purplish gloss. 



Cryptocephalus clavicornis, Chp. 

 (Plate XXVI, figs. 183, 184.) 

 Mr. Masters has given me under this name a pair of in- 

 sects from the Clarence River which differ from Chapuis' 

 description in having the head rather coarsely punctate 

 and the tibiae of the male entirely black. I believe, how- 

 ever, that they are correctly named, as the antennae are 

 peculiar and exactly as described. 



Cryptocephalus bihamatus, Chp. 



(Plates XXII, XXV, XXVI, figs. 30, 139, 140, 141, 142, 

 158, 185, 186.) 

 An unmistakable species, at least as regards the male. 

 A remarkable character of the male, not mentioned by 



* In several collections I have seen specimens of jachsoni bearing 

 the name viridinitens.
