1224 SYNANTHEDOK By B. Zfkowsky. 
S. mardia Drc. (176 d) is allied to tryphoniformis Wkr. (177 b) from which it differs as follows: forewing 
and hindwing quite hyaline, discal spot and the spot at the apex beautifully reddish orange instead of yellowish 
brown. Head, thorax and abdomen black instead of yellow as in tryphoniformis . Anal tuft broad and bright 
reddish orange. Antennae black, palpi orange. 18—19 mm. Mexico: Durango. 
S. pallene Drc. (176 d). All the wings hyaline, veins black, apex and distal margin of fore wing broadly 
golden brown. Head, thorax and abdomen black. Collar, base of thorax and the last abdominal segment orange. 
Underside of the head, thorax and abdomen yellowish brown. Legs and antennae black, the antennae 'white 
near the tips. 13 mm. Mexico: Teapa, Tabasco; March, April. 
S. tryphoniformis Wkr. (177 b). A : coppery black, face silvery white, palpi yellow. Antennae black, 
dark rust-coloured below. Thorax with four yellow stripes, the sides and pectus yellow. Abdomen compressed 
at the base, the posterior margins of the segments whitish, yellowish laterally, white beneath. Anal tuft rather 
long with a few dingy yellow hairs. Legs dingy yellow, femora black above, tibiae black at the base. Wings 
transparent, iridescent, fringes coppery and very short. The doubtful $ shows the antennae scaled below’ at 
the base. Posterior margins of the segments dingy yellow’. Legs pale dingy yellow, tibiae partly browmish at 
the ends. Wings with longer fringes. Forewing purple with dingy yellow streaks in the distal area and a yellow 
streak right across the discal vein. 20 mm. Para: Villa nova. — According to Butler it is said to be synonymous 
with the following ischniformis Wkr. and plectisciformis Wkr. 
S. plectisciformis Wkr. <$: purple. Head green, face white. Palpi yellow. Antennae black, rust-coloured 
below. Thorax with two yellow stripes on each side. Abdomen with a yellow band on the posterior margin 
of each segment. Anal tuft with very few yellowish hairs. Legs dingy yellow, striped black. Wings transparent, 
fringes very short. Forewing purple with a yellow’ streak along the costa, distal area striated yellow’, discal 
vein purple. 18 mm. Para. 
S. ischniformis Wkr. <$: purple. Face and orbita white. Head yellow behind. Palpi yellow, strongly 
haired. Antennae slender, very much longer than the blue thorax. Abdomen with yellow bands on the posterior 
margins of the segments. Underside and anal tuft below’ yellow. Legs yellowdsh, anterior coxae white, hind 
tibiae and joints on the posterior tarsi with purple bands. Wings transparent, fore wing with purple golden 
margins, distal area and discal vein! 12—13 mm. Para. 
S. santanna Kaye (477 b). (Described as Aegeria.) Collar white. Head and thorax bronze blue with 
two narrow yellow segmental bands (not discernible on the figure). Legs bronze blue, with narrow yellow bands. 
Forewing beyond the cell, thus the whole distal area, entirely bronze blue, also along the costa; discoidal vein 
darker blue. Hindwdng transparent with narrow black margins. 19 mm. — The species is w’ell discernible from 
other Synanthedon- species by the completely dusted distal area. Trinidad, St. Ann's; December. 
S. martenii sp.nov. (176 f) is somewhat similar to pallene Drc. (176 d). Antennae, head, thorax and 
abdomen blackish blue. Palpi yellow’, white before the eyes. Thorax with two yellow’ lateral stripes. Abdomen 
with traces of yellow rings on the posterior segmental margins, anal tuft black. Pectus yellow’, ventrum distinctly 
belted yellow, anal tuft yellow’ below. Legs blackish above, yellow beneath. Forewing transparent, costal vein, 
margins, the broad discal vein and the veins black. A narrow distal area, higher than broad, remains transparent, 
behind it towards the distal margin a beautifully copper-red band which is only bordered by the black distal 
margin and traversed by 5 black veins. Hindwing transparent, veins and margins black. The rather long fringes 
of all the wings greyish brown, the anal region of the hindwing hairless. 20 mm. Brazil. Rio de Janeiro ? October. 
Type in the Coll. Marten. 
S. tetranoma Meyr. Head dark purple reddish, in front and the collar orange, face whitish. Palpi orange,

rings. Ventrum orange. Anal tuft broad, dark blue, white above, mixed with yellow’ on the sides. Legs quite 
orange. Forewing iridescent hyaline, anal margin yellowish, veins and costal margin dark brown beyond the 
cell, red lines at the basal part on 12 and between 9 and 16, cross-vein edged with red, a narrow reddish distal 
band, the veins in it thickly black. Hindwing hyaline, veins and margin dark brown. 23 mm. Peru: Iquitos; 
March. 1 <$. 
S. sallustiformis Drc. (176 e). Forewing whitish hyaline, costal margin, apex and veins black, hindwing
