costa of the primaries yellowish; the latter wings with a 
blackish spot at the end of the cell, and a curved 
abbreviated blackish discal line running downwards from 
the subcostal vein ; secondaries with the external area 
faintly tinted with yellowish ; a brown dot at the end of 
the cell; legs above slightly tinted with yellow ; expanse 
of wings, 11 lines.

November, 1874; Rio Jutahi, 29th January, 1875. 
Three specimens and a fragment of a fourth were 
obtained at light ; in coloration it differs entirely from 
S. eburneata, although very similar in pattern. 
Macaria ? turturaria of Walker is referable to Soma- 
tina. 
After examining and comparing the genera Acidalia 
(including several perfectly distinct genera), Timandra, 
Ochodontia, &c., with the Macariide, I have come to the 
conclusion that some of the species confounded together 
under the generic name Macaria could be advan- 
tageously referred to the present family under the generic 
names proposed for them by Hubner, but ignored by 
Guenée. 
The type of Macaria is necessarily M. litwrata since 
that is the sole species given by Curtis, but Geometra 
alternata, Denis, and Phalena notata, Linn., are certainly 
not congeneric with the insect, but agree in almost every 
respect with Ochodontia sareptaria. The following species 
are referable to Parasenna of Hiibner, to which genus 
these two well-known European forms belong :—Macaria 
emulataria, noptaria, discerptata, enotata, agnitaria (type 
of the genus), clararia, approximaria, tectaria, emersaria, 
shanghaisaria, and insistaria ; it is probable that many 
other species unknown to me will fall into the same 
genus, and if Ochodontia be still retained as a group of 
Acidaliide, so close to Timandra that M. Guenée and 
others would not separate it, 1 do not see how we can 
place Parasemia in a distinct family ; if we do, we must 
add to it Timandra aventiaria of India, which, although 
it has the general aspect of a Timandra, is structurally 
a Parasem.a, ‘
