Australian Fruit Flies — FlARDY 
173 
It is distinguished from the other Australian 
species by the characters given in the above 
key. 
TYPE LOCALITY: "Nouvelle-Hollande, Ade- 
laide.” 
Type in J. E. Collin’s collection (the 
Bigot collection), Newmarket, England. 
Froggatt (1907) recorded the species from 
near Bathurst, New South Wales, ”on trunks 
of wattle trees.” 
Bezzi (1913), Tryon (1927), Hendel (1928), 
and Malloch (1939^) have listed it as an 
Australian species. Malloch apparently erred 
when he stated: "the given type locality, 
Tasmania, is undoubtedly erroneous as 
usual.” 
CALLISTOMYIA Bezzi 
Callistomyia Bezzi 1913. Ind. Mus. Mem. 
3: 124. 
This genus is distinguished from other 
Trypetinae which have four scutellar bristles 
by the short, stout, closely spaced spines on 
the ventral surface of the apical halves of the 
middle and hind femora. The known species 
are easily recognized as Callistomyia by the 
presence of a very large spot in the apex of 
the wing. This completely fills all of the 
apical three-fourths of cell R5 and a large 
part of cell M2. The wings are also charac- 
terized by a transverse band through the 
middle of the wing extending from the 
costal margin to the hind margin through 
the r-m crossvein. The chaetotaxy of this 
genus has been discussed by Malloch 
(1939^: 447). 
genotype: Callistomyia pavonina Bezzi. 
KEY TO KNOWN SPECIES OF Callistomyia 
1. Abdomen with black bands on the an- 
terior margins of terga 2 to, and in- 
cluding, 4 in the males and 5 in the 
females 2 
Abdomen not banded, except on the 
base of tergum 2 in one species .... 3 
2. The large apical spot in the wing is 
joined with the transverse band 
across the middle of the wing in the 
lower part of cell 1st M2 (Philippine 
Islands) icarus (Osten Sacken) 
The apical spot is isolated, not joined 
to the transverse band (India- 
Formosa) pavonina Bezzi

This is the only species of the genus which 
has been recorded from Australia. It is 
separated by the characters brought out in 
the key. According to the original description 
the abdomen is entirely rust-red and the 
mesonotum has five longitudinal black vittae. 
The specimen at hand appears to fit the 
original description except that the second 
abdominal tergum has a broad, black band 
on its anterior margin and the mesonotum 
has just three dark vittae. 
The species at hand may be new, but since 
just a single specimen is present I prefer to 
treat it as horni with a query. The following 
description is based upon this specimen. 
MALE. Chiefly reddish. Head: Brownish- 
red in ground color, occiput yellowish. Front 
slightly expanded below the middle and two 
times longer than wide. The front possesses 
two pairs of inferior fronto-orbital bristles 
and two pairs of superior fronto-orbitals. 
The middle portion of the face is flat and 
nearly straight from the lateral view. The 
antennae are yellow, and the third segment 
is not much over half as long as the face 
and slightly over two times longer than wide. 
The longest hairs on the aristae are about 
equal to one-third the width of the third 
segment. Thorax: The chaetotaxy fits the 
generic arrangement given by Malloch (1939 
h\ 447) except that no humeral bristles are
