Broun's Fruit Fly. 



(PI. I, fig. 3.) 

 Dacus (Tephrites) xanthodes, Broun. 



(Transactions of the New Zealand Institute, XXXVII, p. 327, 1904.) 



This name was given to a species, bred by Captain Broun in New- 

 Zealand, from larvae obtained infesting pine-apples, granadillas, guavas, and 

 mammee apples brought from Suva and Rarotonga, Fiji. 



He says : " It differs from Trypeta psidii in being longer, differently 

 coloured and sculptured, and having no dusky areas on the wings. From 

 Dacus tryoni it is distinguished by a greater length of body and expanse of 

 wing, uniform coloration, without fuscous or yellow marks, dissimilar 



thing and sculpture, less broadly oviform or wasp-like hind body and 

 stout antennal setae. In D. tryoni the flanks of the sternum are fuscous." 



Before describing this insect, Captain Broun sent me several specimens, to 

 see whether I could identify it for him ; but we have never bred this species 

 from imported fruit, and it has never been recorded from Australia. 



Briefly, it may be thus described : Length of body, 4J lines ; expanse of 

 wings, 7i lines ; eyes dark, face unspotted, with very few black bristles on 

 the head ; general colour, pale ochreous yellow, with the tarsi brownish, and 

 the abdomen somewhat darker than the thorax. A faint yellow dorsal 

 stripe on thorax, running through the centre of the scutellum, with a pale 

 yellowish-white stripe margining each side and marking the sides of the 

 scutellum, which is very prominent and arcuata behind ; only a few black 

 bristles on either side of the thorax. The wings are hyaline, with only the 

 costal nervure and the next parallel vein slightly ochreous ; abdomen of 

 female elongated, and truncate at apex. 



The Large Australian Fruit Fly. 

 (PI. Ill, fig. 11.) 



Dacus cequalis, Coquillet. 

 (Proceedings of the Linneau Society, N.S.W., 1908.) 



This is one of our largest fruit-flies, and is remarkable for the very broad, 

 dark ferruginous stripe along the front margin of the wing, the long antennae, 

 and very wasp-shaped body. Several specimens were obtained by Mr. A. T. 

 Hunter in the maggot state in oranges growing near Gosford, New South 

 Wales. These maggots were bred out in the Entomological Laboratory, and 

 found to be a very different species to the common Queensland fruit-fly. 

 When in Washington last year, I submitted specimens to Mr. Coquillet for 

 determination. He has since sent me a technical description for publication 

 under the above name. This description has been published in the Proceedings 

 of the Linnean Society of New South Wales for this year, (1908). 



The type will, therefore, be in the National Museum at Washington, U.S.A. 5 

 a second specimen I presented to the Entomological Collections of the Imperial 

 Research Laboratories at Pusa, India ; and another co-type is in the depart- 

 mental collections in Sydney. It comes close to Dacus lounsburyi, Coq., from 

 South Africa, and Dacus longicornis, Wied., from India and Java.
