is also very neatly ciliated in black. Halters orange. Legs all orange: front femora 
with the usual two back rows of bristles and a very stout row of 6 bristles below: 
the coxae have two very stout spines and a few others: tibize spurred. The middle 
femora are hairy; the tibie have a row of 5 stout though comparatively strong 
spines in the middle part (somewhat nearer base) on tip, a crown of orange spines 
with one excessively strong black one below; all the tarsal joints have the curious 
stout spines at the basal sides of each joint that are found in A. cesio (Harris). The 
hind femora have 3 or 4 stout spines on the apex in front, tibize with a central row 
of some 7 spines in front: the long Ist tarsal joint has beautiful golden hairs on it: 
each joint has two basal spines, smaller than those on the middle legs. 
Abdomen. Orange at base merging to black towards the end of 2nd segment : 2nd 
segment very long, next two about equal, last about as long as previous two ; triangular 
in profile. The globular hypopygium is orange: it is complex, and in profile can be seen 
a pair of upper scales and a pair of lower more pointed ones. 
The last segment of the abdomen bears a border of very strong downward pointing 
spines; the rest of the abdomen is covered with short bristly orange hairs, the marginal 
ones being scarcely longer.

Head. Eyes bare. Top view :—frons orange-yellow, rather shining but 
minutely granulate: margins and ocellar area and vertex a little greyer. Lunule 
demarcated by a red arc. Frons quite parallel-sided: in this view the Ist and 
2nd joints of antenna are seen to be very bristly, the former with 3 or 4 longish 
pale bristles, the latter with many small black ones, chetotaxy normal, viz. 3 pairs 
rather con. front f. 0., two pairs parallel and backwardly bent hind f. o., the pair nearer 
vertex being smaller and crossing the very stout parallel upright 1. v. ; 0. v. smaller, white, 
p- v. the same, parallel and well down head; between the o. v. and p. v. is another 
similar bristle, and these bristles (viz. o. v., p. v., extra pair) are continuous with the 
very stout post-orbital row (extending half-way down eyes) and like them are white.
