c 
P. mitnica Druce (22 k) strikingly copies Phaeosphecia opaca (10 c). Posterior tibiae and tarsi striped mimica. 
ochreous-yellow, forehips spotted white. On the bluish-black forewings there is at the base a green silvery spot; 
below the base of the cell a red-brown stripe in the prolongation of which there is a green silvery, blurred spot. 
The hindwings are hyaline below the base of the cell. — The species was described from the Amazon, it is before 
me also from French Guiana (Nouveau Chantier) and East Colombia (Villavicencio), thus apparently widely 
distributed. 
114. Genus: Xantliopleursi Hmps. 
The genus contains rather large species mostly resembling Calonotus. On the forewings the upper 
median vein rises near the cell-angle from which the lower radial veins rise. Cell of the hindwing long, the 
lower median vein far from its lower angle, from which the 1st median vein and the lower radial rise; the middle 
radial rises rudimentarily from the middle of the transverse vein, the upper one and the subcostal vein on a 
short pedicle from the upper cell-angle; the costal vein is short and rudimentary. 
N. perspicua Wkr. (= sandion Druce) (21 k) entirely resembles the following species and differs p?rspicua. 
only by the light greenish-yellow colour of the abdominal stripe and a minute hyaline spot above the rise of 
the 2nd median vein of the forewing. Colombia; Ecuador; Peru (Pachitea); Amazon (Para). 
N. troetschi Druce (21 k) is perhaps only a northern race of the preceding; it merely differs by the iroetschi. 
orange-yellow colour of the abdominal stripes; of the small hyaline spot above the 2nd median of the forewing 
which is said to be absent, there are anyhow traces noticeable in one specimen before me. Only from Panama 
(Chiriqui). 
N. flavocincta Guer. Black, antennae at the base of the shaft striped white; spots on the collar, as fiavocinda. 
well as narrow dorsal and broad lateral stripes on the abdomen are metallic green. Shoulders, chest and legs 
spotted white. The 1st abdominal ring and the anal tuft are yellow. Some lateral spots on the abdomen are 
white. Wings hyaline with broad black borders and median band. Expanse of wings: 45 mm. Cayenne. 
115. Genus: Chlorostola Hmps. 
Only 2 large species coloured black and golden green, with hyaline spots, erect palpi and doubly combed 
antennae. Thorax long-haired. On the hindwings the lower median vein rises before the cell-angle, the upper 
one and the lower radial on a common pedicle, the middle radial being absent. The abdomen shows on the 
posterior rings lateral, short hair-tufts and on the last segment longer ones. 
Ch. interrupta Wkr. (22 b) differs from the following species by the abdomen exhibiting metallic green interrupia. 
transverse bands above the second and third segments and green subdorsal spots on the other rings, lateral 
and sublateral rows of white spots. On the forewings the 2 small hyaline spots in the middle of the cell are 
absent. Mexico. 
Ch. corydon Druce (22 b). Black, forewings in some places suffused with metallic green, with 2 small corydon. 
hyaline spots in the middle of the cell and one below them, 2 at the cell-end and one below it and 4 behind 
the cell; hindwings with 3 small hyaline spots at the base and 2 behind the cell. Antennae black, before the 
tips white. White spots on the collar and shoulders. The abdomen exhibits bluish-white subdorsal spots. 
Mexico: Jalapa, Orizaba (March to July); Guatemala: Vera Paz. 
116. Genus: Ixylasia Btlr. 
It differs from the preceding genus merely by the thorax not being woolly haired and by the absence 
of hair-tufts on the last rings. On the hindwings the middle radial is imperceptibly represented. Some species 
show lateral hair-tufts at the base of the abdomen. 
I. trogonoides Wkr. (22b). Black; tips of the antennae and palpal base white. Hindhead, collar, trogonoidcs. 
shoulders, shoulder-covers, and hips with white dots. The hair-tufts at the abdominal base are brown. Lateral 
bands on the abdomen and long stripes in the basal half of the black forewing are metallic green. Lateral spots 
on the 2nd abdominal ring and sublateral rows on the others are white. Hindwings hyaline with black veins 
and marginal band. Expanse of wings: 56 mm. Brazil. 
I. pyroproctis Druce (= kelleri Klages) has a black body; palpal base and dots behind the eyes are pyroproctis. 
white. Collar, shoulders, shoulder-covers, and thorax spotted white and metallic blue. Forehips spotted white. 
Hair-tufts at the abdominal base of the brown and white. The abdomen exhibits on the 1st ring a dorsal 
bluish-white dot; the last segment and a band at the penultimate ring are above scarlet; laterally and sublaterally 
there are rows of white spots, the lower ones being longer; the 2 last rings are beneath spotted orange. Wings
