Tn general appearance like C. fAirsalis, or a very small C. 

 pallida, but, on those species, the series of punctures on the 

 elytra are quite easily counted; on all the other pallid species 

 (including an immaculate variety of C. crassicornis), the elytral 

 punctures are in more or less regular series. All the claws are 

 thickened towards base, and, although not acutely dentate, from 

 certain directions a subdentiform extension maybe seen on each; 

 the species has, therefore, been referred to Calomela, but might 

 have been, with almost equal justice, referred to Chrysomela. 



Phyllocharis jansoni Baly. 



There are numerous specimens before me (from Mackay to the 

 Coen River) belonging to this species, or to varieties of the same, 

 but only one agrees entirely with the original description. All 

 the others have the undersurface (except most of the abdomen) 

 pale, and the femora (knees excepted) also pale; the scutellum is 

 sometimes infuscated, but is usually pale. On the typical form, 

 the postscutellar spot extends as a wedge to well beyond the 

 middle; on one specimen, it is continued until it becomes con- 

 joined with the subapical spots. 



Var. A. — By the description, differing from the typical form 

 only in the colour of the legs; I have not seen such a variety; 

 the nearest to it being a specimen that has two small spots on 

 the prothorax, forming, with the one on the head, the corners of 

 an equilateral triangle; its postscutellar spot is short, wider than 

 long, and with its apex trilobed. 



Yar. B. — A specimen (from Somerset, the locality of the 

 variety) is evidently Jacoby's var. B; its prothoracic spots are 

 large and of irregular size, the cephalic spot is also of large size. 



Var. C, n.var. Head with a feeble, infuscate spot, prothorax 

 immaculate, elytra dark metallic-bl-ue, margins and base pale. 



Var. D, n.var. Head with a feeble, infuscate spot, prothorax 

 immaculate, postscutellar not extending to beyond the post- 

 humeral ones, and rounded or truncate at its apex; one specimen 

 differs in having the posthumeral spots connected with the sub- 

 apical ones.
