Hah. Mackay and Cairns, Queensland (^Turner). 



A species very variable in colour. In specimens from Cairns 

 the yellow markings are much reduced in size. 



In the male the yellow marks on the median segment are 

 sometimes wholly absent. The posterior ocelli in this species 

 are very near together, about twice as far from the eyes as from 

 •each other.

Though the colour of the pile on the female is more brilliant 

 and the sculpture on the median segment rather stronger in 

 females from Australia, I cannot detect any appreciable difference 

 in the male. 



Hah. Mackay to Cape York, Queensland {Turner).

Hah, Tasmania [Saussure) ; Adelaide, S. Australia ; Mackay, 

 Queensland ; Adelaide River, Northern Territory. 



Saussure's desci'iption seems to have been taken from a head- 

 less specimen, but I think there is little doubt that it is identical 

 with Kohl's species. It is allied to L. mansueta Sm. from New 

 Guinea. 



Larra pejuorata Sauss.

Hah. Sydney, N.S.W. ; Mackay and Cairns, Queensland. 



North Queensland specimens differ a little from southern ones 

 in the shape of the pygidium, pronotum, and third cubital cell ; 

 the antennae also are a little stouter. But the differences are 

 very slight and do not seem sufficient to merit specific rank. 

 L. rufipes Sm. from Celebes and L. mendax Sm. from Halmaheira 

 are slight geographical variations of the same species.
