in flaviventris but rather smaller ; the other parts of the 

 elytra are metallic, varying from green and blue to various 

 shades of gold and purple.

(Plate XXII, figs. 34, 35.) 



The female of this species, of which I have taken many 

 pairs in cop., was described by Chapuis in 1875 as coming 

 from Victoria, the male was subsequently described (also as 

 from Victoria) by him as Loxopleurus piostremus. In 1877 

 Baly described the female as Bhombosternus p)retiosus. In 

 both sexes the head varies from entirely red to half red 

 and half black.

Cryptocephalus iridipennis, Chp. 

 var. Idiocephala chapuisi, Baly. 



(Plate XXII, figs. 36, 37.) 



The Rev. T. Blackburn (in T. R. S. S. A., 1893, p. 140, 

 by a slip of the pen speaking of the species as iridiventris) 

 calls attention to the fact that Baly's /. chapuisi is a 

 variety of this species. 



In the female^ and occasionally in the male, the elytra 

 are frequently purple instead of green, and even when 

 green the outer parts are usually purplish. 



The pale portion of the elytra sometimes covers most of 

 the surface, but in the female usually about half; it is often 

 more or less triangular in outline and sometimes forms a 

 short broad V) ^^ ^^^Y ^^^ specimen (a male from Mackay) 

 have I seen the two colours sharply defined, as they usually 

 run more or less into each other, and in the males the pale 

 portion is often scarcely traceable.
