Australian Species of Chrysomela, Phyllocharis, 6c. 175 



Sp. 5. Phyllocharis nigricorms, (Fab.) 



Oblonga, nigro-eenea; capite, thoracis lateribus, elytrorura ma- 

 cula duplici basali ferrugineis. 

 Long. 4| lin. 



Chrysomela n'lgricornis, Fab. Ent. Syst., i. 318, n. 55 ; Syst. EI., 

 i. 455, n. 79; Oliv. Ent., v. 540, tab. 

 4, fig. 43. 



Oblong, brassy black. Head ferruginous, a frontal patch and 

 antennae black. Thorax narrowly margined, brassy black, 

 beneath and on the sides ferruginous, sides broader and slightly 

 rounded in front, anterior edge concave, its angles obtuse. 

 Elytra nearly four times the length of the thorax, sides nearly 

 parallel in front, slightly excavated behind the shoulders ; surface 

 finely punctured, brassy black ; on the shoulder are two small 

 ferruginous spots placed obliquely, more or less confluent; the 

 second sometimes entirely wanting, the two together forming a 

 short narrow patch, which runs obliquely inwards: sometimes near 

 the apex of the elytron is a small marginal spot the same 

 colour. Abdomen blue-black, the base and apex ferruginous. 



The two specimens in the Banksian Cabinet, from which 

 Fabricius drew his descriptions, are mucli injured by time. In 

 the observations on the preceding insect, I have pointed out my 

 reasons for keeping them distinct ; they are nevertheless very 

 closely allied. 



Sp. 6. Phyllocharis fiexuosa, n. sp. 



Ovata, nigra; capite antice, thoracis margine lineisque, elytro- 



rum margine lineaque flexuosa fulvis. 

 Long. 3 — 4 lin. 



Ovate, rather broader behind. Head fulvous, vertex and an- 

 tennae black. Thorax twice as broad as long, its sides nearly 

 straight, parallel, front margin slightly excavated, feebly lobed in 

 the centre, anterior angles obtuse ; surface smooth, sides of the 

 base excavated and coarsely punctured ; the side and front mar- 

 gins, a central vertical line (sometimes interrupted in its middle), 

 and a short one on either side, attached to the border in front, 

 fulvous. Scutellum smooth, black. Elytra black, ovate, rather 

 broader behind, scarcely wider than the thorax at their base, nearly 

 four times its length; surface finely punctured, punctures arranged 

 in striae near the suture, irregular on the sides, nearly obso-
