REVISION OF COELIDIINAE 189 



Remarks. Males of this species are unknown, but the female of kirkaldyi can 

 be separated from females of other long-headed species, particularly oxyomma, 

 by the crown with prominent lateral carina and deeply recessed disk.

 Jassus neoguttatus Distant, holotype <j>, New Caledonia, 5.xii.io,i4 (P. D. 

 Montague) (BMNH, London). 



New Caledonia: Col d'Amieu, 650-800 m, 5 $, 21-23. iii. 1968 (T. C. Maa &• J. L. Gressitt); 

 Mt des Koghis, 400-600 m, 4 $, i. 1969 (N. L. H. Krauss); Mt Panie trail, 1 $, 8— 9. ii. 1963 

 {N. L. H. Krauss); Bourail, 1 9. "i- *959 (N. L. H. Krauss). 



Biology. Unknown. Collection records indicate that this species is prevalent 

 from January to March. 



Remarks. From robusta, to which it is similar, vittata can be distinguished 

 by the very broad crown which is somewhat carinate laterally above antennal 

 sockets. 



Tharra terminalis (Walker) comb. n. 



Coelidia guttata Walker, 1870 : 313. Holotype §, Raja Ampat Is. (West Irian) (BMNH, 

 London) [examined], [Homonym of Coelidia guttata Walker 1851.] Syn. n. 



Coelidia terminalis Walker, 1870 : 314. LECTOTYPE <$, Raja Ampat Is. (West Irian)
