64 ENDOPARASITES RECORDED IN QUEENSLAND. 
APHANIPTERA 
The presence of the cysticercoid stage of Dipylidiwm 
caninum L. (a tapeworm, which infests cats and 
dogs in Queensland) in the cat flea and dog flea 
(Ctenocephalus felis and C. canis respectively), 
may be inferred. Likewise also the cysticercoid 
of Hymenolepis diminuta of rats, in Ceratophyllus 
fasciatus, one of the rat fleas. The lastnamed 
ectozoon is also known to be the chief transmitter 
of Trypanosoma lewisi, which is a blood parasite 
of local rats.

According to Dr. Cleland (Trans. Int. Med. Congr. 
Austr. 1913, p. 566), the correct name of the blow- 
fly known here as C. oceanica is Anastellorhina 
augur Fabr.

a Leptomonas ( Herpetomonas) musce-domestice, Burnett, 
Jnstn., 1916¢ (Brisbane). 
According to Dr. Cleland (l.c., p. 550), the blow-fly 
identified as C. villosa is really Pollenia stygia, 
Fabr. 
CULEX FATIGANS, Wied. (syn OC. skusii, Giles), common 
- house mosquito. 
The organism of dengue is transmitted by this 
mosquito. 
Dirofilaria immitis, Leidy (heart worm of the dog).* 
Bancroft, 1893, 1898, 1900, 190la, 1903a, 19030. 
*Dr. G. Sweet (1908, p. 485), has misquoted Bancroft, 190la, in 
reference to Anopheles maculipennis as the intermediate host of Dirostlaria 
immitis in Queensland. Bancroft states definitely (p. 43, 1901), that 
this mosquito does not occur in Australia (1903, p. 251).
