absent, 7 sinuate upwards and approaching 8 anteriorly. 
Probably allied to Homcidaula, the rather peculiar palpi and 
superficial appearance similar, but neuration of hindwings excep¬ 
tional.

Frodidactis mystica, Meyr. 
I am indebted to Mr. A. Busck for indicating to me (for reasons 
based on the genitalia) that this very peculiar genus and species 
should properly be referred to the Hyponomeuticlce. I then per¬ 
ceived that what I had described (Exot. Micr. iii, 163) as the 
broken base of the palpus was really a complete but rudimentary 
palpus. The genus Frodidactis was briefly characterised in Ann. 
Transvaal Mus. viii, 52 (1921), being at that time regarded as an 
abnormal form of the Tortricidce. I now give complete characters 
as a Hyponomeutid : 
Head with appressed scales; ocelli posterior; tongue developed. 
Antennae |, <$ filiform, simple, scape moderate, without pecten. 
Labial palpi extremely short, filiform, porrected. Maxillary 
palpi extremely short, filiform, porrected. Posterior tibiae with 
rough hairscales above, $ with very long expansible hair- 
pencil from base above. Fore wings 1 b furcate, 2 from j, 3 from
