minute basal trunk or entirely absent. An example of the latter situation 
is M. (= Tribonica) eremitis Meyrick, from Ceylon. It is strange that the 
unstable nature of this vein in M cr idarchis seems to have escaped attention, 
as we find no record of this fact by other authors. It is not possible to 
separate the genera Meridarchis and Tribonica by the aid of this feature, 
as not only gradual transitions can be found connecting separate species 
together, but also in individuals of the same species, and even in left and 
right hind wing of a single specimen vein 6 may be differently developed. 
This is rather unsatisfactory in view of the importance ascribed by 
Meyrick to the presence or absence of this vein. We were accordingly 
obliged to revise the above key to the genera of the Carposinidae. 
In all the following species the labial palpi in the male are rather short 
and subascending, in the female only moderately long, or even short and 
porrect but tending to be subascending (M. anisopa spec, nov.); the 
terminal segment in the two sexes is very short, exposed and narrowed.
