ture, and there is therefore some reasons to expect that ma- 

 ture specimens may possess the markings here mentioned, 

 more developed, or may possess markings, not mentioned 

 here.

 1851; Chr. vicina Kempnt, Verh. zool.-bot. GeseJlsch. Wien,

 1914. — This species was well-represented in the collection. 

 Queensland: 1 specimen, Yarrabah; 2 specimens, Chillagoe; 

 4 specimens, Christmas creek. N. W. Australia: 2 specimens, 

 Broome; 11 specimens, Kimberley district, February. 



It was very interesting to see that this wide-spread Au- 

 stralian species to some extent was liable to vary. The 

 smallest specimen (Kimberley) measured 20 mm in expanse 

 of forewing, the largest one (Christmas creek) 33 mm. In 

 some specimens the basal antennal joint was unmarked, in 

 other specimens it was marked with a dark (reddish) dorsal 

 stripe, but in most specimens both a dorsal and a lateral 

 streak were found. In several specimens the two dark oblique 

 streaks on the vertex were wanting, or only indicated by two 

 small döts. In other specimens the crossveins and anal veins 

 of the forewings were quite påle, but this was, as far as I 

 could see only due to the lesser degree of maturity. 



Chrysopa signata Schneider, Monogr., p. 109, tab. 35, 

 1851. — Of this species a fine series of specimens was pre- 

 sent. N. W. Australia: 7 specimens, taken in February, from 

 Kimberley district. Queensland: 1 specimen, Christmas creek, 

 November; 1 specimen Bellenden Ker; 1 specimen, Yarrabah; 

 2 specimens, Atherton. W. Australia: 2 specimens, taken in 

 September, from Freemantle.
