HEMIOSLARIA; THURBERTPHAGA; PERANIA; MINOFALA; BELLURA. By Dr. M. Draudt. 315 
0. rhodoxantha Dgn. (45 i) is a smaller species not quite corresponding with the diagnose of the genus, rhodoxan- 
because, the anterior tarsi have a normal length. Forewing yellow, the basal half of the costal margin and the 
proximal border of the anterior transverse line are broadly powdered with red-brown, the marginal area being 
purple pink; transverse lines red-brown, the anterior line on the submedian fold very pointedly dentate, the 
posterior line double, its proximal part intensely purple pink; maculae absent. Hindwing yellow, on the veins 
and margin pink. Paraguay. 
170. Geims: M emioslarla B.u. Benj. 
Separated from the preceding genus by the better developed though not very long proboscis; in the 
cordiform, edged frontal projection there is a vertical central listel which is connected with the lower end 
of the edge, below it a horny plate; the thorax is clad with scales and hairs, the prothorax and metathorax 
each exhibit a loose tuft, the anterior one being very small; anterior tarsi with very strong spines. Abdomen 
with a tuft on the first ring. But one species was reported hitherto. 
H. pima B. <£• Benj. (46 c). Thorax white, abdomen orange-yellow. Forewing lustrous white, the pima. 
transverse lines only indicated by costal-marginal dots and below the submedian fold by fine, undulate black 
lines. Hindwing black with white fringes. Expanse of wings: 33 to 36 mm. Arizona. 
171. Genus: Tlmrfoerlplaaga Dyar. 
Very closely allied to Oslaria from which it differs in the different frontal projection representing a 
truncated-conical appendage provided with a raised edge and with a feebly scarred place in the centre; the 
proboscis is fully developed, the short palpi are porrect. But one species the larva of which is known as ..pink 
bollworm“ of wild cotton (Thurberia) and may do much harm in Texas and Arizona; the imago flies in August 
and September. 
0. diffusa Barnes (= catalina Dyar) (46 c) is light yellow on the forewing, between the veins very diffusa. 
feebly scaled orange with a pink median band which is in the middle connected with a similar marginal band 
by a broad pink longitudinal patch being above distinctly defined and below faded; the marginal band is 
distally dentate; fringe pink. Hindwing yellowish, in the distal half strewn with pink. Expanse of wings: 
35 mm. Arizona. 
172. Genus: Perania B.u. Benj. 
Proboscis moderately developed, palpi erect, projecting beyond the frons which exhibits a large conical 
projection ending above pointed and being below' hollowed out; thorax scaled with very feeble small tufts, 
abdomen tufted on the first rings; anterior tibiae not armed. But one species externally recalling Stibadium 
(p. 293). 
P. dissociata B. <£• McD. (46 c). The olive-brown forewing is much darker in the basal half than in dissociata. 
the distal half, the border being formed by a still darker nebulous stripe beginning from the centre of the costal 
margin, extending to the lower cell-angle, from here in a rectangular break to the centre of the hind-margin; 
the distal transverse line is indistinctly double. Hindwing smoky grey. Expanse of wings: 34 mm. Utah. 
173. Genus: Minofala Sm. 
Proboscis somewhat stunted and only moderately long, palpi short and slender, not reaching to the 
conical frontal projection which is above provided with a rough cavity with a raised edge; thorax scaled, tuftless, 
also the abdomen tuftless, tibiae not armed. But one species. 
M. instans Sm. (46 c). Forewing dingy light yellow, strewn with brown and white, with double, instans. 
interrupted transverse lines filled with whitish, and with a blackish faded longitudinal stripe from the middle 
of the anterior transverse line to the margin above the centre; the small maculae are whitish, only the ring- 
macula is surrounded by black; the apex is parted by an oblique light patch, the undulate line has above some 
small black sagittary spots in front of it. Hindwing whitish, distally smoky with a dark central luna and post¬ 
median line. Expanse of wings: 26 mm. Texas. 
174. Genus: ISellaira Wkr. 
We combine here, in accordance with Barnes and Benjamin, the former genera Sphida and Arzama 
being chiefly only distinguished by the presence or absence of a small roundish projection being besides hidden
