Avhole bare except for a few black hairs on the sides of the 

 lirst three segments. Legs with femora black, covered be- 

 low with fulvous scales; tibiae fulvous; tarsi black; an- 

 terior and middle femora with a few black bristles towards 

 the apex, the posterior femora with a complete row of 

 black bristles below ; tibiae with numerous very long black 

 bristles ; tarsi with the joints marked by spurs. Wings 

 hyaline, with dark brown costal margin, and suffused dark 

 brown sipots on middle of first basal cell, apex of second 

 basal cell, anterior cross-vein, base of cubital fork, the two 

 branches of cubital fork, outer veinlet of discal cell, and 

 middle of veinlet closing discal cell below; the angulation 

 •of the discal cell below is frequently marked by a small 

 veinlet entering the cell. 



Variation. A male taken at Mangalore on November 

 8, 1913, differs considerablv from the type, the colour 

 being pale grey instead of fulvous, and the long hairs on 

 the first antenual joint white instead of yellow, also in the 

 wings the upper iDranch of the cubital fork has a small 

 veinlet on its lower side. 



This species may be readily recognised by its humped 

 appearance, bristly thorax and legs, narrow bare abdomen, 

 and spotted Avings. I had not noticed an}^ specimens prior 

 to 1913, but during the November of that and the follow- 

 ing year, it occurred not uncommonly, either settled in the 

 sunshine on bare ground, or frequenting flowers. My 

 dates range from November 8 to November 29, but it pro- 

 bably remains on the wing for some time longer. 



BoMBVLius (Sensu Jato). 



A large number of Australian species have been describ- 

 ed under the name Bovihyliiis, bub most of these do' not 

 belong to the genus m its restricted sense. I have examin- 

 ed the specimens in the collection of the British Museum, 

 which contains all Walker's t) pes, and find that the sjDecies 

 seem to fall into four natural groups, distinguished by the 

 closed or open first posterior cell, and the relative length 

 of the first and second basal cells. Another character 

 that shows great variation is the form of the radial vein, 

 which is almost straight in some species and boldly curved 

 up in others. At first I considered that this character 

 might provide generic distinctions, but a careful examina- 

 tion of the different species has led me to the conclusion 

 that it is of specific value only. Confiraiation of this view 

 is supplied by the gen:is Ccm/ptosia, in which a similar 

 'diversity in the form of the radial vein occurs. The Aus- 

 tralian species described under BombyUus I place in four
