COSMO SOMA. By Dr. M. Draudt. 
rcgestum. C. regestum spec. nov. (14 f) differs from the preceding species by its considerably smaller size, quite 
orange-yellow head and collar; palpi and antennae black; shoulder-covers orange with a narrow black middle 
streak; hips orange, forelegs and middle legs otherwise blackish-brown, hindlegs orange, the distal end of the 
femur and the proximal end of the tibiae above black. Abdomen orange, the two last segments black; the others 
exhibit a dorsal row of spots, and a double lateral one on each side of the middle rings. Wings hyaline; base 
of the forewings and subcostal space as far as the black apical spot, as well as the extreme inner-margin 
orange; the space between the latter and the inner-marginal vein black. Colombia (San Antonio, 1800 m), 
1 d' taken by the light at night-time (Fassl leg.). Type in Coll. Seitz. 
exsors. C. exsors spec. nov. (14 f) is smaller and neater than the preceding, with broader and shorter wings; 
differs by its black head, the shoulder-covers being bordered with black clistally and at the apex, by a more 
intensely orange-red ground-colouring, larger black dorsal spots, only one lateral row of black spots. On the 
wings only the base is orange-red, the subcostal space faintly yellowish hyaline, the proximal margin quite 
black. Another distinguishing mark is the cell-fold on the forewing running here separately and above the 
middle radial, whereas in regestum it is shortly behind the cell united with this. Described according to 1 £ 
of the Coll. Seitz from Colombia (Sosomoco). 
notostida. C. notosticta Dogn. Head orange; vertex, palpi and antennae black; collar and shoulder-covers 
orange, the latter at the base black. Abdomen orange with dorsal and subdorsal rows of spots. Anal-end above, 
the 2 last rings beneath black; legs black and orange, hips orange. Wings hyaline with black fine margins and 
veins, apical spot and angled discocellular; base and subc.osta orange. Expanse of wings: 27 mm. Colombia 
(Aguaca Valley) in August. 
cUrinum. C. citrinum Rothsch. (14 f) without the patria being stated, from the Coll. Felder at Tring, is very 
easily recognizable by the peculiarly brownish apex of the forewing, being densely dusted with yellow. Head, 
palpi and antennae are black, the rest of the body yellow, on the dorsum spotted black; at the base of the forewing 
there is a yellow spot. The species resembles Is. monticola. 
juanita. C. juanita Neum. Head and thorax black, palpi yellowish; shoulder-covers bordered with white. 
Legs red, hips white, abdomen brilliant red, the first ring and the last ones black. Wings hyaline, veins and 
very broad margins and apical spots black. Expanse of wings: 23 mm. Cuba. 
tengyra. C. tengyra Wkr. (= fulviventris Men.) (14 f). Head and thorax blackish-brown; forehead, shoulders, 
thorax, forehips and legs white-spotted. Abdomen yellow. Wings hyaline with blackish-brown veins and 
margins. Forewing with 2 white basal dots. Expanse of wings: 32 mm. Amazon (Para). 
hereyno. C. hercyna Druce (14 f) differs from the many similar species by the unicolorously orange-yellow 
abdomen; the front body is quite black. Distributed from Mexico across Nicaragua as far as Panama (Chiriqui). 
klagesi. C. klagesi Rothsch. (14 g) is somewhat larger than the preceding from which it otherwise differs by 
the white forehead and breast and a white middle spot on the thorax; at the base of the wings two white, small 
spots; the distal margin is black in a more uniform width, the black discoidal spot is absent. Trinidad. 
braconoides. C. braconoides Wkr. (14 g). Except the last 3 segments the abdomen is peculiarly diaphanous brownish- 
yellow, which makes the insect appear repulsive; all the rest is blackish-brown, just like a series of dorsal spots 
varying greatly in extent on the abdomen. On the head and base of the forewing 2 white dots each. Discoidal 
spot very large. Widely distributed in Mexico, also in Honduras. 
stibosticta. C. stibosticta Btlr. (14 g) differs from braconoides by the absence of the discoidal spot and an entirely 
unmarked abdomen. Panama, Colombia, Ecuador, Bolivia. — The white spots on the head, thorax, hips and 
dealbata. bases of the wings may be absent altogether: dealbata form. nov. (= ab. 1 Hmps.) \ but instead there may occur 
caerulescens. metallic blue spots both at the places of the white spots and on the black abdominal apex: caerulescens form, 
nov. (= ab. 2 Hmps.). 
watsoni. C. watsoni Rothsch. (14 g) differs from the similar species by its quite sooty black head and thorax 
and above all by the uncommonly large round discoidal spot and the very broad black apical spot and distal 
margin, the latter of which is proximally very deeply indented between the upper median vein and the middle 
radial vein, so that the hyaline part on the upper median vein comes very close to the margin. Panama 
(Chiriqui; Lino). 
ih\a. C. thia Druce. Head and thorax black, collar yellow, metathorax with metallic blue spots. The 1st 
abdominal ring is black, on each side with yellow spots, the 3 next rings are yellow, the last ones metallic 
blue. Forewings hyaline, costal and inner margins towards the base yellowish, veins brownish-black, distal 
margin and apex broadly black; hindwings hyaline, bordered with black. Expanse of wings: 32 mm. Ecuador.
