SILVIUS MONTANUS Ricardo. 



Si!-i'iifs inontanus Ric, Ann, Mag. Nat. Hist. (8), xix, p. 216, 1917. 



Type from Mt. Tambourine. Queensland. I have recently received two 

 specimens from the Queensland Museum, taken at National Park, Brisbane, Ijy 

 Mr. 11. Hacker. ( )ne of these agrees very well with the type, the other differs 

 in having tlarkcr palpi, less marked wings, and in the abdominal pubescence 

 being white on the segmentations. The eyes are not bare, as stated by Miss 

 Ricardo, but rather thinly pubescent ; tiiis is also the case in the type. 

 SILVIUS FRONTALIS Ric. N.T.. Darwin, Stapleton, Batchelor. I am 

 indel)te(l tn Mr. Hill for this identification. 



In addition to the above there are three species of Silvius in the collection 

 represented liy single specimens and not in sufficiently good condition for describ- 

 ing. ( )ne may prove to be a female of .S". psaroplianes Taylor, which was 

 described from the male. 



Sub-Family TABANINAE. 



Groi'I' IV. Forehead with no callus. (Group numbers are those used by Miss 



Ricardo.) 

 TABANUS ANGUSTICALLUS Ric. N.T., Melville I. Type. 



TABANUS LEUCOPTERUS van de Wulp. 



Tabaiius Icucof'fcnis van de Wulp, Tijdschr voor Entom. xi, p. 98, 1865. 



This species, which clearh- belongs to Miss Ricardo's Group IV, does 

 not appear to ha^e been hitherto recorded from Australia, the type locality 

 being the Aru Islands. Miss Ricardo has, however, identified a specimen in 

 the Museum collection from Stewart River, North Queensland, as this species, 

 and another specimen is in my collection from Kimberley, North-West 

 Australia. Probably it will l)e found to have a wide distribution in the 

 north. 



Group \'TI. .\b(lomen with one or UKjre stripes, usually continuous.
