402 GNATS Oil MOSQUITOES — CHAPTER XIII 



Note. — Mr. Theobald remarks : " In some respects this might bo the 

 C. tcBniorhijnchus, Wiedemann, but as I have seen no banded-proboscis 

 forms of Cidex from lower south than New British Guiana, except 

 Panoplites titillwns and Tceniorhynchus Jasciolatus, I cannot possibly 

 say. I believe, however, that tceniorhynchus, which is so common at 

 New Amsterdam, will be found to extend farther into South America, 

 and that this species of Arribalzaga's will prove to be Culex tcBnio- 

 rhynchus, Wiedemann" (Monog. p. 384). 



20. CULEX ALBIROSTRIS, Macquart ("D. E." Sup. iv, p. 10). 



Proboscis white, except at the base and tip, where it is black. 

 Abdomen with the hinder borders of the segments white ; tarsi blackish, 

 with a white ring at the base of each joint. Length. — Two lines 3 •

Note. — No banded-proboscis forms have been sent from New Zealand, 

 but from the description of this species, the abdomen is pretty clearly 

 apically banded.
