( cv ) 



lateral parts of the mesonotum, give a colour eSect in dorsal 

 aspect of the insect not very different from that of the yellow- 

 tubercled species, e. g. Prosopis rotundiceps, the convexity 

 of the yellow pronotal tubercles rendering these conspicuous 

 in true dorsal aspect. In the scutellum of this Eunjglossa a 

 small triangular, distinctly divided-o£E portion is to be seen 

 on each side. These lateral pieces are often called the 

 " axillae." One would have thought this name would have 

 been used rather for one of the small chitinisations beneath 

 the root of the wings, but it is an unhappy term anyhow ! 



In the specimens determined as Prosopis sp. ? $, Palaeorhiza 

 nubilosa $, Prosopis rotundiceps $, Prosopis nuhilosella $, 

 Meroglossa nigrifrons ? ^, the yellow thoracic markings are 

 identically placed, the side-markings being absolutely confined 

 to the prothoracic tubercles. 



Palaeorhiza nubilosa ?. This $ seems hardly more than a 

 very slight var. of the species I have identified as Prosopis 

 nubilosa, from Queensland. I find it almost impossible to 

 believe it can be another genus. My " nubilosa " have nothing 

 to do with Palaeorhiza (a genus I myself made !), but are 

 Prosopis. Unless you have c^d* of yours, showing the entirely 

 different tongue of a Palaeorhiza, I consider yours Prosopis, 

 and the same species as mine. 



Meroglossa nigrifrons ? <^.* This has no resemblance at 

 all to a Meroglossa and is not that genus. Its face, antennae, 

 etc., are entirely different in structure, not to mention the 

 tongue. In fact I should say it is almost certainly a cJ of 

 Prosopis rotundiceps. 



P. rotundiceps $. This practically agrees with my Queens- 

 land examples I named thus. 



Prosopis sp. $. I have c^^ which may belong to this 

 species, but I have no name for them. I should think it 

 quite probable that this species belongs to the " disjuncta " 

 group of my genus or subgenus Euprosopis, but without very 

 minute examination I cannot be sure from a single ?. 



P. nuhilosella. I have specimens (also $) that I captured 

 at Sydney, June 1904, but I had no name for them.
