9. Head similar to $\ thorax with a narrow, dark, brownish- 

 olive stripe, then a creamy-white along the median, dark choco-

 brown stripe, which does not reach the posterior margins of the 

 segments, rest of the dorsum bright orange-rufous, pubescence 

 black and orange-rufous respectively, lateral pubescence as in ^.

Type 9 i» the Queensland Museum, type ^ in the Institute 

 Collection. 



A species well-defined by its markings and colour. That the 

 (J and 9 represent one species is beyond all doubt, as Mr. Hacker 

 has taken them in coitu. It is remarkable that, in the male, 

 the eyes are not continuous. Beyond this, I can, at present, find 

 no tangible reason for separating this species from Pelecorhynchus, 

 but when specimens of P. maculipennis Macq., and F.fusconiger 

 Walker, are available, their genitalia will be compared. P. 

 mirahilis conforms to the genus Pelecorhynchus in having a 

 hatchet-shaped proboscis, the curved anal vein of the wing, open 

 anal cell, and the subulated antennae.
