St. heterogramma Hmps. (55 k). Hitherto only known in $ sex. It is another similar species. Fore¬ 
wings olive-grey, dusted with reddish brown. Marginal area a purer fuscous, antemedian line very boldly in¬ 
curved at inner margin, the black median line that has a white outer edge, extends more obliquely and is curved. 
Reniform stigma has first a white, then a brown surround. The postmedian double transverse line is intertilled 
with whitish; distally of it there extends from costa, before the apex, a dark shade that lias a whitish inner 
edge, to the margin on vein 3. The hyaline liindwings have black-brown veins and marginal band. British 
and French Guiana. 
Subfamily: Sarrothripinae. 
Also this subfamily is relatively poorly represented in America. It is fairly close to the 2 preceding 
subfamilies. The frenulum of the $ now again consists of several spines that are not conglomerate. The retin¬ 
aculum of the $ is bolt-shaped, cell of forewings, as in the Stictopterinae, with an appression of upraised scales. 
Proboscis is in general well developed, only in the Genus Iscadia it is rudimentary. Palpi long, terminal segment 
often thickened. America is the home of some relatively large species, mostly however these are small insects. 
The larvae have all the usual pairs of legs and are sparsely haired. Pupation takes place in a boat-shaped cocoon. 
1. Genus: Chas’acoma Wkr. 
Proboscis developed, palpi with long terminal segments, antennae ciliate. Thorax scaly and with a 
large tuft posteriorly, also abdomen with 2 basal tufts. The stumpy and wide forewings bulge forward at base 
of costa, they have a long and a narrow appendicular cell. Vein 4 is absent on liindwings, as it anastomoses 
with vein 3; 3 and 5 are stalked. Only 2 species are found in America, whilst the Genus is widely distributed 
otherwise over India and Africa. 
Type. Ch. albulalis Wkr. from Borneo. 
Ch. nilotica Roghfr. (= chamaeleon Mschlr., littora B.-Bak., laurea Drc.) (55 i). A highly variable 
small species of almost universal distribution (compare Vol. 3, p. 290, Vol. 11, p. 385 and Vol. 15, p. 180). 
Forewings grey intermixed with brownish black. Transverse lines and stigmata described in Vol. 3. All the 
forms mentioned therein, as the following, also occur in America: nigrimotata Warr. (55 i) with black antemedian 
band, — nigrimacula Warr. with round black basal spot at costa, — submediana Strd. with black central spot 
in submedian area and — basibrunnea Warr. with brown basal area and inner margin. A form with pure white 
wide antemedian band and brownish postmedian area is named albifascia /. n. (55 i). The species occurs in 
America from Texas right through Mexico, Honduras to Costa Rica. It is also found on the Bahama Islands, 
in Cuba and Porto Rico. The larva feeds on Tamarix articulata. 
Ch. deleta Hmps. (55 i) has an ochreous whitish body. Forewings are brownish with 3 very indistinct 
transverse lines and a subterminal row of dark dots. Marginal area somewhat shaded. Hindwings transparent 
white, brownish in marginal area. Only 1 <$ from Peru (Calloa) is known. 
2. Genus: Pardaseita Wkr. 
This almost exclusively african Genus is represented in America by 1 species. It differs from Characoma 
by the absence of a tuft on thorax, abdomen has a small tuft only at base. On hindwings vein 4 is also absent, 
3 and 5 arise from lower angle of cell, otherwise everything is like in Characoma. 
Type. P. roeselioides Wkr. from Africa. 
P. miochroa Hmps. (55 i). An insignificant, small species with greenish grey forewings bestrewn with 
reddish brown. Transverse lines blackish, the anterior one double, a whitish patch containing 2 black dots at 
disco-cellular nervure. Subterminal line grey with brownish black edges on both sides; a few minute black 
dots at margin. Hindwings uniformly black-brown. Described from Colombia. 
3. Genus: &arrotlirfJ»us Curt. 
This mainly indo-australian Genus is represented in Europe and Asia and also in America by one re¬ 
presentative. The details of the Genus are given in Vol. 3, p. 289 and Vol. 11, p. 390. 
Type: S. revayana Scop. 
S. revayana Scop, occurs in its innumerable forms in N. America from Canada to California and Arizona. 
The species is fully dealt with in Vol. 3, p. 290 and illustrated in a number of forms on pi. 53 c and d. 
4. Genus: JLoj»iiosema Hmps. 
Proboscis rudimentary and not able to function. Palpi very long, somewhat enwidened at terminal, 
frons with tuft, antennae faintly serrate and ciliate. The scaly thorax has an appressed tuft and also the
