row of punctures, joined to the third row at the apex, the basal 

 margin likewise flavous, the rest of the interstices finely punctui'ed 

 and transversely wrinkled ; claws joined at the base, the thii'd 

 joint dentate at the apex. 



Hah. Brazil. 



I know of no other species of Zygogrmnma with flavous thoracic 

 margins in which the elytra ai-e so strongly punctured or the 

 interstices finely so; the subsutuxal flavous stripe gradually 

 approaches the suture towards the apex : in the variety the 

 antennse and legs ai-e fulvous, and the femora ai-e spotted with 

 feneous, but other differences I cannot find. The punctation of the 

 thorax varies much in depth and number of punctures, and the 

 elytral wrinkles ai-e also more or less distinct in different specimens. 



Zygogramma argentinensis, sp. nov. 



Dark greenish, the antennag black ; thorax minutely punctured, 

 the sides more strongly so ; elytra with three narrow fulvous 

 vittse, the discoidal ones joined at the apex, tlie marginal one 

 with a row of punctures, the subsutural rows geminate. 



Length 9 millim. 



Larger than any of the species placed in this genus described 

 by Stal, of an opaque greenish colour, the head minutely 

 punctured, the terminal joint of the palpi larger than the pre- 

 ceding one ; antennae black, the basal two joints flavous below,- 

 terminal joints widened ; thoi'ax very finely punctured, the sides 

 more strongly so ; scutellum impunctate ; elytra I'Cgularly 

 punctate-sti'iate, the subsutural row double (the fii-st row con- 

 sisting of a few punctures only), the third, fifth, and ninth 

 interstices flavous, the discoidal bands joined at the apex, the 

 fourth interstice rathei' wider than the others, the marginal 

 flavous vitta with a row of piceous punctures, elytral epipleurte 

 greenish ; claw-joint dentate, claws joined at the base. 



Hah. Salta, Argentine Republic. 



The larger size, greenish coloration, and the wider fourth inter- 

 stice separates this species from its allies ; the flavous bands are, 

 as usual, joined together by the similarly coloured flavous basal 

 margin. There are three specimens before me. 



Zygogramma curvato-lineata, sp. nov. 



Dark fulvous, the bi'east greenish seneous ; thoi-ax finely and 

 sparingly punctured ; elytra flavous with a metallic lustre, each 

 elytron with the following black markings : three shoit stripes at 

 the base, the inner two joined at the apex, a semicircular band 

 below the middle, another one within the outer band, and a 

 V-shaped mark near the apex ; legs fulvous. 



Length 8 millim. 



Head impunctate, fulvous ; antennae with the terminal joints 

 moderately thickened, longer than broad, entirely fulvous ; thorax 

 very sparingly and finely punctured at the base and sides, fulvous; 

 scutellum black; elytra punctate-striate near -the suture, finely
