238 Mr. E. Meyrick's descriptions of 



beneath, terminal joint very short, thick, truncate. Maxillary 

 palpi modferately long, thick, filiform, somewhat thickened termi- 

 nally, truncate. Abdomen in male with small anal tuft, valves 

 retracted. Posterior tibiae with outer spurs half inner. Fore wings 

 with vein 10 rising out of 9, 11 very oblique. Hind wings rather 

 broader than fore wings ; veins 3, 4, 5 approximated at base, 7 out 

 of 6 near origin, anastomosing with 8 to near middle. 



81. Chnauvd octaviaUs, Ld. 



Chnaura octaviaUs, Ld., pi. xvii., 4 (nee Walk.) ; 

 Syncjamia secutalis, Walk., SuppL, 1291. 



Apart from structure, this species may be immediately 

 distinguished from the following by the absence of the 

 black basal band of the abdomen. Lederer was mistaken 

 in identifying this with octaviaUs, Walk., which is a 

 synonym of Synf/amia nicriojialis, Walk., as explained 

 below, and some of the localities quoted by him are 

 therefore also erroneous. 



New Hebrides (Mathew) ; several specimens. Occurs 

 also in New Guinea, Amboina, Aru, and Siam. 



Syngamia, Gn. 

 Forehead somewhat rounded, oblique ; ocelli present ; tongue 

 well developed. Antennae four-fifths, in male filiform, moderately 

 or shortly ciUated (^ — 1), with angularly projecting scales at joints. 

 Labial palpi moderate, arched, ascending, second joint with dense 

 projecting scales beneath, terminal joint very short, almost con- 

 cealed. Maxillary palpi moderate, rather thick, filiform. Abdomen 

 in male with small anal tuft, valves retracted. Posterior tibiae 

 with oiiter spurs half inner. Fore wings with vein 10 approxi- 

 mated to 9 towards base, 11 oblique. Hind wings rather broader 

 than fore wings ; veins 3, 4, 5 approximated at base, 7 out of 6 near 

 origin, anastomosing with 8 to middle. 



ALtlialocssa, Ld., cannot be maintained as a distinct 

 genus; Lederer founded it on Jloridalis, Z., alleging as 

 characters to distinguish it from Si/iifianiia the porrected 

 (not ascending) palpi and the longer ciliations of antennae, 

 but the first character is non-existent, the palpi being 

 (juite as in Si/n;i(iiiii(i and CJuKdira, whilst the second is 

 merely speciiic and certainly affords no basis for generic 

 separation.
