(2) Sitlamita opioia, sp. nov. 



I separate this somewhat hesitatingly from the first, but the puncturation of 

 pronotum and elytra (especially of the former) is very much more scattered and 

 superficial, and the anterior lobe of pronotum is more constricted. Pallid cinereo- 

 testaceous, punctures brownish-testaceous. Eyes, inner margin of corium in great part, 

 and a spot near the middle of apical margin, also extreme apex — blackish-brown. 

 Pronotum more or less clouded in the middle. Beneath pallid testaceous, sterna 

 blackish.

Pale sanguineous spotted all over (including femora and tibiae) with black 

 tuberculate spots, except on the more or less infumately luteous membrane. Pubescence 

 mixed, pale and black. First segment of antennae pale fulvous, second more or less 

 fulvous, third and fourth black. Spines of posterior tibiae and the apical segment 

 of posterior tarsi, black. Cuneal suture generally narrowly pallid, wings iridescent 

 (violet, purple, crimson, and green). Abdomen above blackish or livid. Ventral 

 surface pale luteous, spiracles black. Vertex somewhat faintly longitudinally impressed. 

 First segment of antennae somewhat incrassate, second 4|- times as long as first, 

 five-sixths longer than third, 2^ times as long as fourth, and subequal to base of 

 pronotum. Rostrum scarcely reaching beyond intermediate coxae. Pronotum not 

 (or very slightly) transversely impressed. Posterior femora greatly incrassate, tibiae 



' As far as I have yet been able to ascertain, separate copies of Renter's paper were issued 1878,
