similar, but the two minute orange spots on the meso- 

 thorax are wanting ; the scutellum is broader and more 

 quadrate, the posterior angles rounded, and it is not nar- 

 rowed posteriorly as in P. excellens ; the abdomen has the 

 first, third, and apical segments yellow; in other respects 

 the two species agree in colour, sculpture and form, and 

 possibly one is a variety of the other. 



Hah. — Australia (Champion Bay) . 



In the British Museum. 



In the Transactions of this Society (third series, vol. 

 ii. p. 393) I described three new species of Paragia; of 

 one of these, P. vespiformis, only the female was then 

 known to me; subsequently, however, both sexes were 

 taken by Mr. Du Boulay, and the male was described in 

 the Transactions for 1868 (p. 250) ; this sex is remarkable 

 for the extraordinary form of the basal segment of the 

 abdomen, I have therefore given a figure of that sex in 

 the plate that illustrates this paper (PI. YI. fig. 2) . 



Since I published the last consecutive list of the species 

 of the genus Paragia, numbering thirteen, I have added 

 three in the volume for 1868, two others are described in 

 the present paper, making the number of known species 

 to be eighteen.
