D. tigris Guen. (= lineata Wkr.) (52 k). Forewings yellowish white, dusted with brownish and numerous 
rusty red transverse lines. A large quadrangular deep brown spot, edged with white, between the stigmata and 
a wide lilac nebulous streak behind the cell. Hindwings pale yellowish. Mexico to Colombia and Venezuela. 
D. morata Schs. (52 1). Forewings white with deep reddish hue with sharply outlined oblique coppery 
brown in apical half. Transverse lines double, indistinct, inter filled with white. Blackish cell spot between the 
stigmata that have white surrounds and which are conjoined by white over the mediana. Black sagittate marks 
anterior to the whitish subterminal line. Mexico (Coatepec). 
D. dosceles Dyar (52 1). Forewings bright reddish, costa brown, dusted with lilac grey in marginal area 
with fine brown transverse lines, the anterior one displaced almost to centre, double; the posterior line three¬ 
fold and obtusely crenulate. Between this line and the wide black-brown central shade, a large rose coloured- 
reniform stigma which is joined to costa by a patch of the same colour. Hindwings yellowish. Mexico (Zacualpan). 
D. panteles Dyar is rose-grey, paler at base, blackish at costa. Anterior curved transverse line cuts off 
a small segment both from the orbicular and claviform stigmata that have pale surrounds. Posterior to these 
there is a deep black oblique shade from the costa to claviform stigma. Posterior to the reniform stigma which 
is finely black and protracted with brown concentric surround, there is a finely black crenulate postmedian. A 
deep black shade extends before the twice angulated subterminal line. Hindwings grey-brown. Mexico (Tehuacan). 
D. argillophora Dyar has a more protuberant process on frons than the other species and forewings are 
slightly excurved below apex. Pale straw yellow, whitish yellow at base and with a finger shaped dark brown 
extension in centre of wing. Postmedian yellow-white with brown inner edge conjoined to apex by a white 
oblique streak having a wide deep red-brown shade posteriorly. Hindwings outwardly deep crimson-brown- 
grey. Panama. 
68. Genus: Cliobata Wkr. 
Structure as Diastema, but thorax covered solely with scales. There is only one species: 
Ch. discalis Wkr. (= concludens Wkr.). Forewings white, dusted with golden brown and copper and 
sparsely peppered with black. Transverse lines double intertilled with white, with white oblique line from the 
outer line to the margin along the submedian fold. The stigmata are white spots conjoined with white along 
the mediana, between them there is a U-shaped black line. An oblique whitish streak extends from reniform 
stigma to apex. Subterminal line with dark inner shade. Hindwings whitish, shaded with coppery brown at 
margin. Cuba, Haiti. 
69. Genus: Exyra Grt. 
Biologically a remarkable little group, as the larva inhabits the can-shaped trap of the insectivorous 
plant Sarracenia without being harmed by the digestive juices. The imago is of similar structure to Diastema. 
Frons with an almost beak-like process covered with rough hairs. Thorax with coarse hairs, intermixed with 
spatulate scales and without crest. Abdomen long and also without crests. 
E. rolandiana Grt. (52 1) has deep crimson-brown forewings with a large yellow spot in central area from 
the middle of cell to inner margin. Transverse lines very indistinct. In $ marginal area is grey-brown. Hind¬ 
wings dark brown. East, middle and central States. 
E. fax Grt. Head and thorax orange-yellow. Forewings brownish black peppered with orange. The 
speckles form 2 spots in the cell. Hindwings brown-black. Delaware, Georgia. A very small species of only 
12 mm wing expanse. 
E. ridingsi Riley ( — nigrocaput Morr.) (52 1). Forewings orange-yellow with brown marginal area, 
widely diffuse central shade and wide anterior transverse line. The posterior transverse line is only separated 
from margin by very fine ochreous dusting. Hindwings glossy brown, yellowish at base. Central and southern 
States, Texas. — The larva feeds on Sarracenia. 
E. semicrocea Guen. (52 1) The largest species, glossy black, orange in basal half. Hindwings black- 
brown, pale yellow at base. Middle, central and southern States. — ab. hubbardiana Dyar from Florida has 
grey marginal area with prominent wide dark central and subterminal bands. — ab. immaculata Benj. has a 
unicoloured grey marginal area without the dark bands. There are all sorts of transitions between these forms. 
The larva is white with deep red bands and inhabits the pouches of Sarracenia variolaris and flava. It spins 
up the opening and feeds on the inner surface of the green tissue and does not touch the captive insects.
