Calochromus guerini, Macl. 



Two specimens, from Cairns, differ from the typical form 

 of this species in having the prothorax red, except for a 

 narrow dark median line; another, from Dorrigo, has the pro- 

 thorax normally coloured, but the elytra entirely red. 



Calochromus insidiator, Fairm. 



A male, from the Tasmanian Lakes, and three others, 

 from Ulverstone, have a blackish triangle about the scutellum, 

 and so, at first glance, appear to belong to C . scutellaris, but 

 the head is unarmed. 



Calochromus amabilis, Lea. 

 Three males, without exact locality labels, from the Black- 

 burn collection, probably belong to this species ; they have the 

 punctures about the tips of the elytra decidedly coarser than 

 elsewhere, and similarly thick antennae to those of the types, 

 the apical marking, however, is briefly transversely-elliptic, 

 instead of slightly advanced along the suture, and concave 

 between the suture and each side. The antennae are decidedly 

 shorter and thicker than those of the male of G. basalts, but 

 the elytral interstices are intermediate between those of that 

 species and amabilis. 



Calochromus denticulatus, n. sp. 



o" . Blackish-purple; prothorax, scutellum, and elytra 

 (except apical sixth) lemon-yellow. 



Head with a flange-like process overhanging and con- 

 cealing labrum ; a narrow median line at base, ending 

 between antennae in a small, deep fovea. Antennae long 

 and thin, first joint stout, second very small, third wider 

 and shorter than fourth, the others to tenth subequal in 

 length, and very feebly decreasing in width, eleventh 

 slightly longer than tenth. Prothorax almost twice as wide 

 as long, a large sinuous depression near each side, and a 

 narrow one along middle. Elytra almost parallel-sided ; 

 punctate-striate, punctures partially concealed by pubescence, 

 but becoming more distinct about apex, where the striae 

 vanish; alternate interstices somewhat elevated above their 

 fellows. Front femora, rather stout; with two rows (two or 

 three in each row) of small teeth, or acute granules, on under- 

 surface near apex;, front tibiae denticulate on lower-surface. 

 Length, 12 mm.
