collection in the Macleay Museum, Sydney, contains a number of 

 Odonata from this latter locality; and as these are all species 

 which I obtained myself further to the west, I propose to include 

 Albany in the South- Western District. The following localities 

 were worked carefully and thoroughly: — Perth and Fremantle 

 (Mungar's Lake and Swan River), Armadale (Canning), Busselton 

 (Vasse), Bridgetown (Blackwood), Wilgarrup (Warren district), 

 and the Margaret River and Karridale district. Besides these, 

 I am much indebted to Mr. G. R Berthoud, of the State Farm, 

 Hamel, for sending me a large number of specimens from 

 Waroona (Murray district), thus linking together the northern 

 and southern localities which I myself worked. 



Considering that the district worked was practically new 

 ground, the final result of twenty -six species is perhaps some- 

 what disappointing. Six new and extremely interesting species 

 were found; three or four more may be considered as exceedingly 

 rare and local. The rest are insects found more or less commonly 

 in similar latitudes in the Eastern States. Hence we are enabled 

 to extend the range of many of our eastern species, and to notice 

 their variation under different climatic conditions. The following 

 is a complete list of all the species taken or observed, with notes 

 on all points of interest, and complete descriptions of new species: 



Family LIBELLULID^. 



Subfamily LIBELLULINJE. 



1. Pantala flavescens Fabr. 



Rare; several taken at Waroona by Mr. Berthoud. It is an 

 exceedingly common tropical species, extending to India and 

 North America. In the Eastern States it is common from Cape 

 York down to Clarence River, N.S.W.; and it is met with occa- 

 sionally round Sydney. A large brownish-orange insect, with 

 very broad hind wings. 



2. Tramea Loewii Brauer. 

 Mungar's Lake, Perth. A beautiful large red insect, with a 

 graceful soaring flight. The hindwings have a peculiar black
