BY ARTHUR WHITE. 43. 



A. calceatus. Face bare, grey. Front grey, with a pair 

 of diffused brown spots touching the eye on either side, 

 vertex brown, the whole bearing long black hairs. Pro- 

 boscis brownish-black. Palpi brown. Antennae with the 

 first joint swollen, grey, with long black hairs; second and 

 third black, the former very small, the latter expanded 

 at the base and tapering towards the apex, where it is 

 terminated by a short style. Thorax brown, with five 

 indistinct dark brown longitudinal stripes, the spaces 

 between the three middle lines being dark drab-brown, 

 bounded outside by light yellow-brown. Abdomen black, 

 the sides with white and a little brown pubescence ; the 

 second segment when viewed laterally has a white margin. 

 Legs yellow with the exception of the anterior femora, 

 which have rather more than the basal half black ; tarsi 

 with basal half of first joint yellow, remainder black ; 

 the tibiae bear numerous long black bristles. Wings 

 tinged with yellow; veins yellow, except towards the tip, 

 where they are brown. 



Female resembles the male, but has the front light yel- 

 low-brown, the abdomen very long, and when viewed late- 

 rally each segment with a white hindmargin, and the 

 wings distinctly yellow. 



This species resembles A. calceatus very closely, though 

 it is of somewhat more slender build ; it may, however, 

 be distinguished without much difficulty by the narrower 

 front, with more closely approximated eyes in both sexes, 

 and by the yellower wings. When the date of capture 

 is known its identification should be easy, for, so far as 

 is known, it does not appear on the wing until some 

 time after A. calceatus is over. 



A. montanus occurs 1 very sparingly on rocky ground, near 

 the highest part of the hills that bound the Bagdad Valley 

 on its eastern side. Time of occurrence, January. 



Anabarrhynchus latifrons, Macq. 



A slender black species. Front with upper two-thirds 

 deep shining black, lower third white ; thorax and abdo- 

 men black ; femora black ; tibiae yellow or brown ; wings 

 hyaline. 



Length. Male, 8 mm. ; female, 8-9 mm 



Hab. Bagdad Valley, Hobart, Wedge Bay. 



Male. Face white. Front with upper two-thirds black, 

 lower third white, the whole bearing black hairs. Pro- 

 boscis black, lying close against the face. Antennae black, 

 the first joint with long black hairs. Eyes widely sepa- 

 rated. Thorax black, with faint indications of grey stripes..
