SEXSERRATA; NEOTARACHE; GROTELLAFORMA; PHOENICOPHANTA. By Dr. M. Draudt. 385 
70. Genus: Sexserrata B. & Benj. 
Denominated after tlie very remarkable process on frons that has six serrations: a beaker shaped pro- 
truberance with forked central horn, the edges themselves each extended above and below in 2 points. Thorax 
scaled and without crest. Anterior tibiae have a horny spine on outer side. Proboscis developed, palpi obliquely 
porrect. Only one species: 
S. hampsoni B. <£■ Benj. Quite unicoloured silkily glossy white, hindwings slightly dusky towards apex, hampsoni. 
On underside fringes with yellowish checks. Wing expanse: 23 mm. California in April and May. 
71. Genus: ]Jfeotaraclie B. & Benj. 
Proboscis weak, palpi obliquely porrect. Frons with beaker shaped protuberance with pointed central 
process. Thorax and abdomen covered with scales and without crests. Tibiae devoid of spines, anterior meta¬ 
tarsus with 3 bold spines. Only one species: 
N. deserticola B. & Benj. Forewings deep olive-brown with white basal area. Posterior to same a trans- deserticola. 
verse band consisting of quadrate spots that are somewhat displaced inwards in the cell. Instead of the reni- 
form stigma 2 conjoined spots. Subterminally there is a band consisting of 3 spots. Hindwings grey-brown, 
paler towards base. Wing expanse: 16 mm. South Nevada, Arizona, California. 
72. Genus: Orotellaforma B. & Benj. 
This Genus reminds one strongly of the Heliothidae Genus Grotella, but tibiae are without spurs. The 
structure is almost iclentcal with that of Exyra, but abdomen is much shorter and scarcely extends beyond 
the hindwings. Frons has a beak-shaped process -with a corneous plate below. 
G. lactea Stretch. (= calora Barnes ) (52 1). Forewings pure white finely dotted with black, in place of lactea. 
transverse lines generally merely only 2 or 3 dots. Hindwings grey-brown with white fringes. Arizona. This 
is the species held by Hampson to belong to Illice and which we had placed in Vol. VI, p. 246 *). 
73. Genus: Flioeiiicopliauta Humps. 
Atrophied proboscis, palpi upturned with short terminal segment. Frons with large rounded corneous 
protruberance that is somewhat truncate below. Thorax scaled and like the abdomen, without crests. There 
is no appendicular cell on narrow forewings. The median subcostal nervule is absent, the 3 lower ones are stalked, 
the uppermost arises from cell. The q has a longish cavity posterior to end of cell so that the nervules arising 
here are somewhat dispersed. On hindwings the central radial is poorly developed from centre of the disco- 
cellular nervure. Only 3 closely related species: 
P. flavifera Hamps. (52 1). Forewings yellow with carmine-red central and marginal areas, the former flavifera. 
enclosed by deep red transverse lines that are edged with yellow on averted sides, the posterior line over the 
centre with a projection outwards. Costa is also widely carmine in the yellow basal area. Hindwings brownish. 
Argentine. 
P. bicolor B. <Sa McD. (52 1) is very similar to the preceding and perhaps only a local race. It is much bicolor. 
smaller, the red central band is distinctly narrower owing to an expansion of the yellow subterminal band. Hind- 
wings pale yellowish brown with rosy tone towards margin. Described from Arizona. 
P. modestula Dyar has deep carmine-brown forewings with 2 wide white transverse lines, the outer one modestula. 
more boldly undulate than the inner, 3 small white subapical costal striations with a fine white line anterior 
to the black marginal line. Hindwings somewhat paler brown. Mexico (Sierra de Guerrero).

74. Genus: Xaiithoptera Guen. 
Small, generally yellow Noctuids with developed proboscis, upturned palpi and rounded protuberance 
on frons with a faint ridge in the centre. Body with scales and without crests. Forewings with usual neuration 
and appendicular cell. The median radial of hindwing is fairly well developed. 
X. rufescens Hamps. (53 a). Forewings white peppered with fuscous, costa and marginal area dusted rufescens. 
with brown. The veins are mostly finely streaked with fuscous. There are 2 fuscous transverse lines of which 
the posterior one conjoins, where it is angulated, with an oblique apical line. Hindwings yellowish white, nar¬ 
rowly brown at margin. Columbia, Brazil, Trinidad. 
X. furcata Wkr. (53 a). Marked like the preceding species, but ground colour of wings is a brilliant furcata. 
yellow bronze with traces of fuscous outline to stigmata. Hindwings white, brownish at margin. Brazil. 
* The Genus Homolagoa (vide p.325) would be better classified here than with the Amphipyrinae.
