Australian and Tasmanian Cryptocephalides. 357 



very narrow black basal edging ; the vertex and a line 

 down the face are brown, and there is a large inverted 

 infuscate triangle on the prothorax ; the prothoracic 

 margins, however, are flavous, as in all the other 

 specimens. 



All these specimens agree so well in their structural 

 details that I have no option but to regard them as 

 varieties of one species although the colour differ- 

 ences (especially of the last described specimens) are so 

 pronounced. 



Cadmus quadrivittatus, Chp. 

 (Plates XXII, XXIV, figs. 10, 111.) 



Only the male was known to Chapuis. The female 

 differs in being larger (Ti mm.) with shorter and almost 

 uniformly coloured antennae, markings on both head and 

 prothorax of a dingy brown instead of black and dark 

 markings quite absent on the elytra under-surface and 

 legs ; in both sexes of the specimens before me the two 

 median prothoracic markings are conjoined at the base. 



Hab. Queensland : Gayndah. 



Cadmtts strigillatus, Chp. 



A female from Canterbury (N. S. Wales) differs from 

 the male (of which I have Victorian specimens before 

 me) in having only the basal markings of elytra (" callo 

 Jiumerali, fascia suhnedia ohliqua ") distinct, the apical 

 spots being scarcely traceable. Chapuis describes the pro- 

 thorax of the female as " hninnco, macula transversa no- 

 tato." In my female the prothorax is black with the 

 anterior and lateral margins obscurely pallid ; its antennae, 

 however, are as in the type female. 



Cadmus trispilus, Chp. 

 (Plate XXII, fig. 11.) 



This species is very closely allied to cxcrcmentaritcs, Suff., 

 differing principally in length and width of antennae. 

 One specimen before me has a large space at the base of 

 the elytra black and also a broad irregular sutural stripe 

 to beyond the middle of the same colour.
