Tlie species which ThcobaKl has identified as C. rubric 

 thoia.c answers in every particular to Skuse's description ot 

 C.procax, and I have no doubt they are the same. JMacquart's 

 description is very inadequate, but since Theobald claims to 

 recognize C. ruhrilhorax, the name may as well be retained.

May be only a variety of the preceding species.

This must be an OMerotatns, for Skuse refers to the 

 " lameilnj of the ovipositor," describing them as " deep brown, 

 elongate. ^■' In Culex the ovipositor is never prominent 

 externally and has no distinct "lamella?.^' Theobald is 

 certainly wrong in his interpretation of the species : the 

 specimens so named by him in the British Museum collection 

 proved to be only light specimens of C. fatigans. 1 have 

 seen no insect which answers to Skuse's description.

Erichson's description would apply equally well to 0. cru- 

 cians, especially as he mentions that the palpi of the male 

 are a little shorter than the proboscis. But in the absence 

 of ])roof of its erroneousness, Theobald^s determination is 

 accepted. Should this species prove to have longer male 

 palpi, the name australis would have to be used for crucians 

 and a new name proposed for the species at present under 

 consideration. The Tasmanian specimens recorded by 

 Strickland (' Entomologist,' 1911, p. 179) with some doubt 

 as Culex frenchii are this species^ but differ slightly from the 

 Victorian specimens. In the latter the basal half of the hind 

 femora is entirely pale, in the former it is mottled on the
