Ferguson— List of Tabanidae 375 



creamy hairs form a series of median spots. Ventral surface dark reddish 

 brown or bhickish with rather broad yellowish segmentations, with long 

 erect black pubescence intermingled with semi-erect silky whitish pubes- 

 cence, these two varieties only visible when viewed from different angles. 

 Legs dark, femora black, tibiae dark reddish, the tarsi more infuscate, almost 

 black. Wings grey, \eins in middle of wing faintly suffused with brown, 

 this much more marked along cross veins at base of discal cell and to a slight 

 extent at fork of second longitudinal ; stigma dark brown, very conspicuous ; 

 appendix present. Long.: 12 mm.; width of head, 4 mm.; wing, 11 mm. 

 Hab. Flinders L Type in South Australian Museum. 



Described from live specimens, all more or less damaged; in some, where 

 extensively abraded, the abdomen appears reddish with a median black stripe. 

 The species comes near T. tasinanlciisis White, but the costal cell and extreme 

 base of the wing are darkly infuscate in that species, which also differs in a 

 number of ways, i.e., size, uniformly black colour, shape of forehead and callus, 

 shape of third antennal joint, etc. It is possible that this is T. gregarius Er., but 

 the description is hardly sufficient to enable one to place that species with any 

 degree of certainty, and it seems better tu risk creating a synonym than to pin 

 Erichson's name to a species which may n(Jt he the one originally described. 

 TABANUS IMPERFECTUS Walk. T., Waratah. A single specimen 

 probably this species but too damaged for certain identifi- 

 cation.

TABANUS NEOCIRRUS Ricardo. 



Tabaiius iicocirnis l^ic, Ann. Mag. Nat. Hist. (Sj, xix, p. 223, 1917. 



In the South Australian Museum collection there is a specimen labelled 

 Type by Miss Ricardo. In her description Miss Ricardo states the type to be in 

 the South Australian Museum. A complication, however, arises from the fact 

 that Aliss Ricardo further states that the type is from Swansea, Tasmania, 

 whereas the specimen labelled type is from South Australia, and is evidently the 

 second specimen Miss Ricardo had before her in describing the species. The 

 South Australian specimen, whether to be regarded as the type or not, represents 

 a very distinct species and one I have not so far seen from Tasmania, and as 

 there are allied forms in Tasmania it is possible that Miss Ricardo was dealing 

 Vvith two ditl'erent species. At the same time till more information can be 

 obtained, the South Australian species must bear the name neocirrus.
