cato. deeply sinuate at the sides and sliglitly serrate above 

 tlic sinnation ; the anterior tibise of tlie male are produced 

 at the outer apical anj^le and furnished with two long spines ; 

 the intermediate feuiora are feebly serrate beneath ; the 

 cijihth joint of the fla^ellnui is strongly thickened at the 

 base and excavated. The labrum of the male has a distinct 

 longitudinal groove from the base, which is also visible but 

 less distinct in the female.

I am not quite sure that my identification of pectinipes is 

 correct. The type of palmata is identical with 'J'ownsville 

 specimens, and differs from ^ Jlavijrons from Mackay in 

 the less produced and less sinuate seventh tergite, in the 

 aljsence of a longitudinal groove on the middle of the labrum, 

 and in the greater development of the pale markings, espe- 

 cially in tiie presence of a large mark on the seventh tergite 

 and of a large U-shaped mark on the mesonotiim. The 

 female differs in the more convex clypeus, in which the 

 lateral grooves are almost obsolete, and in the total absence 

 of grooves on the labrum ; the pygidium has a better-defined 

 pygidial area and is less closely punctured, and the pale 

 markings are more strongly developed, especially on the 

 scutellum, which has a transverse band, not merely lateral 

 spots as in tvpical fluvifrons.

The ditl'erences between the t«'o forms are so small com- 

 pared with the many features in common, especially in the 

 male, that I doubt if they should be treated as more than 

 local races.

I only know the male of this species. It is very near 

 alri/rons and funebris, differing from the former in the serra- 

 tion of the intermediate femora, which reaches the apex, in 

 the yellow colour of the labrum, clypeus, and underside
