428 DESCRIPTION OF 



concealing the honey in the same manner, and with a 

 similar result. 



I have no doubt some wasps would make even more 

 jom-neys in a day than those recorded above. 



• 

 The following are descriptions of some new species 

 referred to in the preceding pages. The first is the 

 Australian honey ant. 



Camponotus esflatus, n. sp.' Operaria. — Long. 

 15 mill. Nigra, tarsis pallidioribus ; subtiliter cori- 

 acea, setis cinereo-testaceis sparsis ; antennis tibiisque 

 haud pilosis ; tarsis infra hirsutis ; mandibulis punctatis, 

 hirsutis, sexdentatis ; clypeo non carinato, antice in- 

 tegro ; petioli squama modice incrassata, antice con- 

 vexa, postice plana emarginata. Hab. Australian. 



The colour is black, the feet being somewhat paler. 

 The body is sparsely covered with stiff cinereo-testa- 

 ceous hairs, especially on the lower and anterior part 

 of the head, the mandibles, and the posterior edge of 

 the thorax. The head and thorax are finely coriaceous. 



The antennee are of moderate length, twelve- 

 jointed ; the scape about one-third as long as the 

 terminal portion, and somewhat bent. At the apex of 

 the scape are a few short spines, bifurcated at the 

 point. At the apex of each of the succeeding segments 

 are a few much less conspicuous spines, which decrease 

 in size from the basal segments outwards. The antenna 

 is also thickly clothed with short hairs, and especially 

 towards the apex with leaf-shaped sense-hairs. The 

 clypeus is rounded, with a slightly developed median 

 lobe and a row of stiff hairs round the anterior border ; 

 it is not carinated. 



The mandibles have six teeth, those on one side 

 being rather more developed and more pointed than 



' In the Linncean Journ. v. I have given figures of this species.
