120 HYALOMIS; DIPTILUM. By Dr. M. Draudt. 
73. Genus: Hyalomis Hmps. 
Small species with broad, hyaline forewings exhibiting on the under surface at the proximal margin 
a hairy cover. The upper median vein and the lower radial veins all rise far separated from the lower cell-angle. 
The hindwings are very narrow and short, pointed, with a long, though extremely narrow cell, so that the trans¬ 
verse vein is very short. The upper median vein and lower radial vein are absent, the subcostal and 1st radial 
vein are long-petioled. The abdomen is not noticeably strangulated. 
H. espia Dogn. Body above black; 4 abdominal rings yellow, the 3 first ones above interrupted by 
black. Underside yellow, legs yellow and black. Wings hyaline with fine black distal margins, apical spots 
and veins; costal and proximal margins yellow. Expanse of wings: 23 mm. Ecuador (Loja). 
H. thyria Druce ( 1 9 d). This small, neat species has a bluish-black body, being white beneath; anteriorly 
below the shoulders there is on each side a red spot. The very faintly yellowish, hyaline wings exhibit very 
narrow black margins. The costal margin of the hindwing is white-haired. From Ecuador and Bolivia. 
H. hypochryseis Hmps. (19 cl). Body black with carmine spots on the anterior chest as in the preceding, 
but the abdomen shows orange lateral spots and an orange underside; orange are, furthermore, the anterior 
side of the palpi, forehead, throat, and spots on the collar, the borders of the shoulder-covers, and the feet. 
The narrow hindwings have above a white, beneath an orange-yellow costal margin and orange-yellow fringes. 
From Brazil. 
H. platyleuca Wkr. (19 d). Body above black, beneath white, forehead margined with grey; tips 
of antennae white; shoulder-covers with a fine yellowish border. Wings hyaline with fine black veins and margins; 
costa of the hindwing white with a black stripe below it. Expanse of wings: 24 mm. Venezuela. 
74. Genus: mti Prittw. 
This peculiar genus contains species distinguished by a great reduction of the hindwings, in some they 
even almost disappear entirely. On the very broad forewings the upper median vein and the lower radial veins 
rise separately; the proximal margin is in several species beneath covered with hair. The hindwings, in case 
they are developed, are narrow, pointed, and the lower radial is absent; the 1st median and 2nd radial rise 
separately. In case they are stunted, they disappear below the forewings, only the separated inner-marginal 
part hanging down as a hairy, small lobe. 
Sect. I. Hindwing's greatly stunted. 
D. telamonaphorum Priitw. (26 1). Body blackish-brown. Throat carmine; hips white; tarsi and under¬ 
side of the posterior tibiae orange-red. The abdomen exhibits above on the 2nd to 4th rings yellowish dorsal 
spots; underneath these rings are whitish. Wings yellowish hyaline with fine black veins, margins, and discal 
spot. On the under surface the veins and the discal spot are orange-red. Expanse of wings: 24 mm. Brazil 
(Minas Geraes, Rio de Janeiro). 
D. flavipalpe Hmps. (26 k) differs from the preceding species by the orange-yellow palpi with a black 
terminal joint, the yellowish-white forehead, orange-red throat, black body with brownish, streak-like spots 
on the collar, shoulder-covers, and thorax. The abdomen exhibits above on the 3 first rings yellow spots. The 
forewings are purely hyaline, not yellowish. Expanse of wings: 24 mm. Argentina. 
D. halteratum F. (= dieides Prittw.) (19 e) differs from the preceding, similar species by the brown, 
not orange-red, colour of the tarsi and veins on the wings beneath, and the very fine, small middle dot being 
situate above the rise of the middle radial. From Venezuela and Brazil (Rio de Janeiro, Sao Paulo), very common 
also in Argentina and Paraguay, almost all the year round on compositae. 
0. proleuca Druce (19 e). Quite black, only the two first abdominal rings are yellowish-white. The 
hyaline forewings are somewhat yellowish; the very much reduced hindwings are black, with yellowish-white 
hair at the proximal margin. From Venezuela; before me also from Brazil (Sa. Catharina). 
D. culex spec. nov. (19 e). In this species the hindwings are the most extensively reduced, so that only 
by means of a magnifying glass we are able to discover yet a very small stump, whereas the forewings are most 
conspicuously broadened. The body is unicolorously brownish-black, the first abdominal rings beneath some¬ 
what whitish. The wings are yellowish hyaline with a very narrow black distal margin; the costal margin and 
veins are brownish-orange. Only one somewhat mutilated example from the collection of the Museu Paulista 
from South Brazil. 
Sect. II. Hindwings developed. 
D. sylpha Dogn. Head and thorax black, forehead and collar margined with white, the collar laterally 
red. Abdomen above with a dark greenish-blue lustre, beneath white, at the end black. Legs black, femora 
inside white. Wings hyaline with fine black veins and margins, at the rise of the middle radial a black dot.
