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



The species is allied to consors but is smaller, the pro- 

 thorax immaculate and with wider margins, the under- 

 surface and legs (except tarsi) pallid, and the scutellum 

 longer and with the basal notch more distinct. In consors 

 and its varieties the punctures on the head (although some- 

 what variable individually) are simple ; in tricolor they 

 are very dense (especially on the black portion), more or 

 less confluent and with the interstices strigose.

Re-described by Saunders as Idiocephala mgosa, as noted 

 in Masters' catalogue ; Saunders regarded the red apex of 

 elytra and golden pubescence of under-surface as sufficient 

 to distinguish it from his similis, but I can only regard 

 them as forms of one species. I have before me a female 

 in which there is the typical red patch of scahrosus, whilst a 

 male (taken in cop. with it by Mr. Masters) has the red 

 patch just traceable, being very small in extent and much 

 darker than usual. In a pair of similis before me the 

 jDubescence of the under-surface is golden in the female 

 and silvery in the male. A male specimen of similis has a 

 distinct greenish gloss on the whole of the upper surface. 



Similis appears to be the typical form, and scahrosus the 

 variety. In both the sculpture of prothorax and elytra 

 varies considerably ; they are fairly common in N. S. 

 Wales. 



Bugifrons, Chp., from S. Australia ami cximius, Chp. 

 (omitted from the catalogue), I can only regard as very 

 slight local varieties. 



Cryptocephalus jacksoni, Guer. 



Originally described from Sydney, but a common species 

 in early summer in N. S. Wales, Victoria, S.Australia and 

 Tasmania ; the sexes are alike in colour. A variety, fairly 

 common in Tasmania, is of a deep purple colour, but 

 occasionally the purple is confined to the elytra.
