136 THE ENTOMOLOGIST ’S RECORD. 
common on flowers and the dry sandy borders of paths in the orange 
groves; and much less commonly a larger species of Bombylius 
(2 exoprosopa) with darkened wings and black tipped copper coloured 
abdomen. A small Stratiomyiid was to be found on the banks of the 
lanes from April 8rd. I noticed the first Tabanid on the 15th April 
and from thence onward they were common and a source of annoyance 
to the horses: a black-winged, black-bodied species ; a small species 
resembling our Vabanus bromius; and an Atylotus (non-British) were 
the most common. I did not see any T. bovinus or T. autumnalis. A 
species of Haematobia also occurred. The first Asilid (? Dysimachus) 
was noted on the 27th of March and another large reddish species 
resembling Hutolmus rufibarbis was extremely common in the fields 
and on the undergrowth of the orange groves for about three weeks 
from the 21st April. A species of Thereva was seen on the 16th of 
April and again on the 22nd May on the eucalyptus leaves. The 
genus Authrar was well represented as might be expected from the 
numbers of their larval hosts the burrowing bees. I haye a note on 
24th April of the occurrence of six different species, none of which I 
had noticed previously; at least two of these were more or less 
common for some weeks. 
In the Syrphidae, Evristalidae were common, and I more than once 
noticed their ‘‘rat-tailed maggots” in dirty tanks near the wells. 
FHristalis tenav, EF. pertinay and EF. aeneus were noted on 16th-20th 
February. A Chrysogaster occurred on 16th March as well as one or 
two species of Syrphidae proper. A  Sphaerophoria and Syrphus 
balteatus were abundant on flowers in the undergrowth of the orange 
groves from 27th March cnwards. A single specimen of a very hand- 
some black and white marked Volucella was seen on 26th May. On 
the whole this large family was not well represented. 
Apart from Musca domestica, Stomoxys caleitrans and one or two 
species of bluebottle, Muscidae were absent, but the first named species 
easily predominated over all other kinds of inseets in numbers and 
persistence as it occurred all the year round. Zachinidae did not seem 
common except for Sarcophagi, some species of that genus being very 
frequent round about the kitchens and latrines. A few flower 
frequenting Tachinids were seen. Anthomytidae were also very scarce 
in species and individuals compared to an English standard. 
Anthomyia pluvialis occurred and was first noticed on 18th February ; 
a species of Hylemia? on 20th March; Alelanochria riparia was not 
uncommon round some of the irrigation tanks, it was noted first on 
29th March. A species of Hyetodesia was abundant near the latrines 
from 12th April onwards; on the 29th of that month I noticed a 
small Anthomyiid fly in some numbers on the trunks of eucalyptus 
trees and a deep blue species (Ophyra’?) was in great abundance on the 
leaves of a mulberry tree on 15th June. The above mentioned species 
were the only Anthomyiids noticed. In the Acalypterate group of 
Diptera I have only records of a Sepsis, very common around the 
latrines in the orange groves from February onwards, and two species 
of Jetanocera which used to occur on eucalyptus leaves. I do not 
recollect ever noticing a Scatophaga. A species of Hippobosca was 
..common among the horses and first observed on the 15th April. 
I noticed that tree trunks which in England afford favourite 
resting places for many species of Diptera did not seem in the least
