and monilifonn.* Proboscis very thick at base, rapidly diminish- 

 ing to a sharp pointed rostrum (two points in elegans} ; the 

 tongue much longer, very slender, bifid at tip (elegans) or just 

 beyond the middle (indica), normally straight (geniculated in 

 indica). Thorax moderately arched. Abdomen slender, 6-seg- 

 mented ; genital organs not conspicuous. Legs very long, especially 

 the hind pair ; tibiae unspurred, metatarsus much elongated, 

 claws simple, long. Wings broad, anal angle distinct, tips rounded ; 

 1st longitudinal vein very close to costa, ending at three-fourths 

 the length of the wing ; 2nd vein beginning at a very acute 

 angle at a quarter of the wing's length, the anterior cross-vein 

 placed at or so close to its origin that both appear to emerge 

 simultaneously, the cross-vein slanting backwards very consider- 

 ably, joining the 4th vein quite near the base. The 2nd vein is 

 bisinuate, ending just beyond the tip of the 1st vein, at some 

 distance from the wing-tip ; the 4th vein straight for two-thirds 

 of its length, thence suddenly curving downwards, ending about 

 opposite the tip of the 2nd vein ; 5th vein forked at base, the 

 branches widely diverging, well curved ; 6th vein distinct to the 

 wing-margin, curved. 



Range. The only previously known species, A. elegans, comes 

 from Corsica and Cyprus. 



Life-history. Unknown, but probably closely identical with that 

 of Blepharocera.

3 . Head: eyes closely, microscopically pubescent, upper facets 

 very distinctly larger than lower ones, divided by a distinct narrow 

 space, the upper ones being about one-fourth the total height of 

 the eyes. l"rons one-third the width of the head, bare, the eye- 

 orbits narrowly silvery ; ocellar triangle distinct, elevated, the 

 three ocelli conspicuous, reddish brown. Face whitish grey, 

 with silvery reflections. Antenna black, bare ; 1st scapal joint 

 much broader at tip than at base, 2nd joint twice as long as the 

 1st, much broadened at tip, where it is produced on the under- 



* The expression " antennas of nine or ten joints " is not intended as defining 

 the precise generic limits of this character, but merely indicates that there 

 seems much uncertainty about them. Bigot, in his original text, gives nine 

 joints; the 1st short, the 2nd much longer and thicker, the 3rd to the 8th 

 small, the last joint ovate. However, in his figure he shows only eight joints, 

 one of the moniliform joints having been omitted. Kellogg (Gen. Ins.) in his 

 figure (PL I, fig. 3) of A. elegans, Big. ("after Schnuse") shows an additional 

 small scapal joint. This is almost certainly incorrect. Then in PI. II, fig. 16 

 (A. elegans. Big., " after Bigot'') an antenna of ten joints is shown, of which 

 the scapal joints are in conformity with Bigot's description and figure, whilst 

 seven flagellar joints are shown irrespective of the ovate apical joint, and of 

 these seven, the first three are larger than the remaining four. It is obvious 

 that the two antennas given in the two plates cannot represent the same species. 

 In my A. indica ten joints are very plainly present.
