60 THE VICTORIAN NATURALIST. 



Hah. — In Victoria on Acacia implexa, Bentham. Specimens 

 collected at Myrniong in January, 1898. 



This species resembles in habits Lecanium casuarince, Mask., 

 inasmuch as specimens were found inhabiting the borings of 

 various lepidopterous and coleopterous wood-feeding insects, so 

 that it would be impossible to discover them without splitting the 

 branches into pieces. The presence of ants in great numbers 

 entering the tunnels is a certain indication of their whereabouts, 

 and is probably the only means of discovering them. 



Externally it is not unlike casuarince, but is smaller and differs 

 in the lobes and rostral setse, as well as in the colouration of the 

 dorsal region. It may possibly only be a variety of casuarince, 

 and I would have been inclined to consider it as such only for the 

 following note from the late Mr. Maskell : — " Your No. 48 is 

 sp. nov. It is a Lecanium, very near to No. 38, which I have 

 named, after the host plant, casuarince. It is very interesting 

 to find two insects occupying similar positions so much alike." 



A NEW SPECIES OF OWLET NIGHTJAR. 

 By Robert Hall. 

 {Read be/ore the Field Naturalists^ Club of Victoria, lOtJi June, 1901.) 

 Two specimens of an Owlet Nightjar (^F'.gotheles) have recently 

 been forwarded to me from the Fitzroy River, North-West Aus- 

 tralia, by Mr. J. P. Rogers. On examination they proved to be 

 adult birds, male and female, and to differ considerably from 

 previously described members of this genus, being nearest in 

 agreement with uE. albertisi, Sclater, from New Guinea. The 

 distinguishing characters are : — The chestnut-rufous on the back 

 of the male is uniform, while that of the female is faintly barred 

 with black ; the wings and tail are almost completely marked 

 with strong rufous, vermiculated with dull blackish-brown, while 

 the nuchal collar is complete. The female is slightly duller than 

 the male. The rictal bristles of the male and female are larger 

 than in the /E. novce-hollcmdice, and there are about one-third more 

 bars upon the central tail quills of each sex. 



The bird is evidently undescribed, and I propose to name it 

 jEgotheles rufescens, the Rufous Nightjar, and append a detailed 

 description of the male. The type specimens will be deposited 

 in the National Museum, Melbourne. 



^GOTHELES RUFESCENS, Sp. nOV.

 head and nape black, with a large amount of rufous on the 

 lateral portions ; collar on hind-neck white, washed at the edges

 tail coverts rufous and barred ; central pair of rectrices
