62. Genus: Griiamptoiiyeliia Hmps. 
Proboscis developed; palpi short, porrect; forehead roughly haired; G antennae serrated and cihated; 
anterior tibiae very short with a long, bent hook inside and a shorter one outside; base of abdomen roughly 
haired. On the forewing the upper median vein rises close at the cell-angle, out of which the two lower radial 
veins rise, accessory cell present, from the lower bordering of which the ripper radial vein rises; the uppermost 
subcostal vein terminates into the costal margin. On the hindwing the upper median vein is petioled with 
the lower radial, the middle one is absent, the upper one on a common footstalk with the subcostal. 
G. flavicollis Drc. (= tiria Drc.) (32 i). Dull black, head and collar orange-yellow, so is the last 
abdominal ring and stripes on the femora. Expanse of wings: $ 46 mm, $ 34 mm. Mexico. 
G. orsola Dyar (32 i) is smaller than the preceding and differs by quite ochreous-yellow ventral side. 
Thorax and forewings are more slate-coloured, abdomen and hindwings blacker. Expanse of wings: 38 mm. 
Mexico. 
63. Genus: Inopsis Fldr. 
In its exterior very closely allied to the preceding; the palpi are beneath more strongly haired, the $ 
antennae partly double-combed, partly simply ciliated; anterior tibiae very much like in the preceding genus, 
posterior tibiae with longer spurs. On the forewing the upper median vein is more remote from the cell-angle; 
the middle radial rises in the <$ above the cell-angle, in the $ out of it, or petioled with the lower one. On 
the hindwing the two lower radial veins are petioled and rise with the upper median vein from the lower cell-angle. 
Sect. I. o' antennae combed. 
I. imitata H. Edw. (= flavicollis Drc., tiria Drc. p. parte) (35 1). Black with a faint blue reflection; 
palpi, forehead, spots on the collar, hips, venter, and anal tuft in the £ orange, in the $ the whole collar, vertex, 
and the greatest part of the legs are orange. Expanse of wings: 36 to 40 mm. Mexico. 
I. catoxantha Fldr. (= tiria Drc. part.) (35 1) is orange on its head and collar, the ventral side, 
in the q except the abdominal end, likewise. The forewings are more bronze-greenish or greenish-blue than 
in the preceding; hindwings black with a blue reflection. Expanse of Avings: 42 mm. Mexico. 
I. scylla Drc. (35 1) differs by its black forehead from the preceding; black with a dull blue shine. 
The A^entral side is likewise orange, in the <$ not quite to the end. Expanse of wings: 42 mm. Mexico to Panama. 
Sect. II. antennae ciliated. 
I. modulata H. Edw. (32 i). Body and foreA\ungs metallic bronze-green; head, collar, hips, femora, 
and venter orange. Hindwings black with a bluish-green shine. Expanse of wings: 40 to 46 mm. Mexico. 
I. metella Drc. (35 1) differs from the preceding by its black femora; the forewings are of a duller 
bronze green, the hindwings more blue with a small whitish stripe below the cell-end. Expanse of wings: 4S mm. 
Guatemala. 
64. Genus: Cyptonyeliia Hmps. 
Closely allied to the preceding genus; the forehead with a large, round projection, the anterior tibiae 
only on the inside rvitli a long, bent spine. On the forewing the venation is almost the same, only the upper 
radial vein rising from below the upper cell-angle, on the hindAving the middle radial vein from abo\ T e the loAver 
cell-angle. 
C. flaviceps Drc. (35 1) is orange-yellow on its head and thorax; palpi, chest, legs, and abdomen are 
brownish-grey. The Avings are yellowish-white, the forewings Avith a basally black costal margin. Expanse 
of wings: 30 to 34 mm. Mexico. 
65. Genus: STyctosia Hmps. 
Very similarly built as Inopsis, but different by the stunted proboscis and longer palpi. Head, thorax, 
and base of abdomen are roughly haired; the <$ antennae serrate and ciliated; on the posterior tarsi there are 
no middle spurs. Venation likewise similar, but the accessory cell of the forewing is absent, the 4 loAver subcostal 
veins all on a common pedicle, only the uppermost rising from the cell and terminating freely into the costal 
margin. On the hindwing the upper radial and the subcostal vein rise unpetioled. 
N. coccinea Schs. (35 1). Body black Avith a faint blue reflection; forewings dull blackish-brownish, 
hindAvings carmine, costal margin and fringes black. Expanse of wings: 38 mm. Mexico. 
N. poecilonotus Dyar (35 m). Forehead dark grey, vertex orange, also the thorax; collar and shoulder- 
covers grey, thoracic sides orange-pink like the first abdominal ring; the rest of the abdomen is bluish-black 
except the orange anal tuft. ForeAvings leaden grey, hindwing with a narrow, grey costal margin and border. 
Expanse of wings: 40 mm. Mexico.
