The genera Aucida Wlk., 7V. Eiil. Soc. Lor,d. (?,). I. p. 2.53 (1802), Pijciwdoutis 

 P'eld., and Leiosoma Feld. are closely allied to one another. In AucuJa Wlk. the 

 second partition of the median nervure to the fore- and hiiulwings is much longer 

 than in the two nneharacterised PVlderian genera. Pycnodonlis Feld. has in the 

 S the antennae more shortly pectinate than Leiosoma I'eld. ; the latter, if really 

 distinct from Pt/cnodontis, requires a new name, as Leiosoma has been preoccupied 

 at least four times. I prefer to treat T^eiosoma Feld. as a synonym o{P;/c7iodontis Feld.

I give the following descri[ition of this genus : — 



Forehead with a tliin conical horn, which is truncate at the tip, and is here about 

 one-tenth as broad as the forehead. Antennae biserially pectinate, branches long, 

 those of the fifth joint already longer than the joint is broad, those of the middle 

 joints more than three times as long as the re.spective joints arc liroad. Second joint 

 of palpi hairy ; third joint more than twice as long as broiid. nearly naked. Legs 

 slenderer than in Fycnodontis Feld., otherwise similar. 



Neuration : similar to that of Pycnodontis Feld. Discocellulars of hindwings 

 concave before vein 5, straight and strongly oblicpie behind it ; vein 5 therefore from 

 below the deepest point of the discocellulars ; second partition of median vein to 

 hindwings shorter than the respective jiortion of the outer margin. 



Typie : Vaularis undidaas Wlk., I.e. 



I do not know the genus Robinsonia Grote from Cuba, but it seems to me to 

 have some affinities to Cnulfiris Wlk. K. .1. 



We insert here, at the end of the Agaristidae, the description of a new species 

 of Sarothroccra>i ^lab., a genus of doulitful ])osition. 



29. Sai'othroceras sordidus Ivothsch. sp. nov. 



]Male. — Upperside : forewings differ from S. pallida (Druce) = alluaudi j\Iab. in 

 the more dirty drab-brown ground-colour, and in the dark sepia-brown subliasal piatch 

 being much smaller: on the inner margin it has a length of 7i millimetres, while 

 in S. pallida it is 12, and in /S. rhomboidea Weymer it is still bigger. Anteriorly 

 its point reaches the hind end of the cell, and its outer edge is concave. The 

 transverse whitish band of pjallida is here much more ill-deiiued, being scarcely 

 paler than the ground-colour of the wing, and is wider, extending to the angle 

 of the inner margin. The apical spot is more defined, owing to the paler ground- 

 colour of the wing. Hindwings as in pallida, but the discal area not red but 

 yellow, and so densely powdered with drab scales as to be very indistinct and faint. 



Underside similar to pallida, but discal area of hindwings yellow, and the outer 

 margin broader. 



P"'emaLE. — Similar to male, but witli tlie subliasal patch on forewings larger, its 

 outer edge straight, and the pale band outside it almost as pale as in jxdlida.

This, as well as rhomboidea Wcym., St. E. Z. 1892. p. 104, on receipt of more 

 material, may prove to be only aberrations of pallida (Druce), but at present 1 jirefer 

 to keep the three species separate. W. K.
