510 Mr. J. KE. Collin’s Description of 
first joint porrect, second and third drooping, third 3-4 
times as long as wide, and pubescent. Only one fronto- 
orbital bristle and that pointing forwards. Mouth-edge 
projecting in front. Palpi projecting slightly beyond 
mouth-edge and bristly at tip. Proboscis geniculate, the 
middle part long, the small paraglossae bent backwards. 
The type-species, R. magnicornis from Formosa, is stated 
to have a distinct bristle at end of second antennal joint 
directed forwards, palpi dull black, arista black, only one 
pair of dorso-central bristles with a row of fine hairs in 
front, acrostichals present ending in a pair of prescutellar 
bristles. 
Another species, R. rugosiscutata Meij. from Java, appears 
to agree with magnicornis in having only one pair of dorso- 
central bristles, but the frontal triangle is dull black, and 
the scutellum and greater part of pleurae is “ runzelig 
und dadurch ziemlich matt.” It agrees more with apicalis 
in having only a very weak bristle at end of second antennal 
joint pointing forwards. 
Neither magnicornis nor rugosiscutata have a darkened tip 
to wing.

The following species all belong to the genus Milichia 
as at present restricted, though ‘they differ considerably 
from the type species (speciosa). The bare mesopleurae 
appear to keep them out of the genus Rhynchomilichia, 
which they approach in the structure of the proboscis. 
The species described below as M. farquharsoni is the most 
aberrant in chaetotactic as well as other characters. It 
is considered. advisable to retain them all in the genus 
Milichia until a better knowledge of the group has been 
attamed. 
1. M. argyratoides, sp. n. Plate XVII, fig. 1. 
Dull, dark brown species. Abdomen of male almost 
entirely silvery. Only two parts of dorso-central and 
fronto-orbital bristles. Face exceedingly short. Third 
antennal joint darkened. 
6. Head and thorax dull dark brown. Frons wide, at vertex 
quite five times as wide as third antennal joint is deep, and widening 
out slightly towards antennae. Frontal lunule with a pair of
