DESCBIPTIONS OF NEW SPECIES OF SYNTOMID.E. 117 



Very near C. sectinota, Hamps., but may be distinguished by 

 scarlet basal marking of fore wing. 



Cosmosoma pellucida, sp. nov. 

 $ . Head, thorax, and abdomen black ; frons white ; teguhe, 

 patagia, and thorax with patches of metallic blue ; fore coxse white in 

 front ; legs streaked with blue ; abdomen with sublateral red stripe 

 extending along first five segments ; ventral surface white excepting 

 last two segments ; wings hyaline with veins black, and margins 

 broadly black. Fore wing with terminal band very wide on apical 

 area, and expanding considerably at tornus ; inner margin heavily 

 bordered, especially near base ; a hyaline streak between costal vein 

 and costa ; a large discocellular patch. Hind wing hyaline, with 

 terminal band very wide on apical area, and expanding at tornus. 

 Under side of fore wing with short metallic blue streak on costal vein, 

 and metallic blue patch in and above basal part of cell of hind wing 

 below. 



Hab. Brazil. 



This species bears a superficial resemblance to Plteia sperans, 

 Walk. ; but the hind wing has vein 3, which is given off from 4 

 just before margin. 



Euchromia coelipunctata, sp. nov.

 crimson dorsal patch on first segment ; a lateral crimson spot on 

 second segment, and ventral and lateral crimson bands on next three 

 segments. Fore wing with a minute metallic blue spot at base near 

 costa, and small blue spot on discocellulars ; a small hyaline spot 

 below base of cell ; a spot in cell, and patch below it ; a spot above 

 vein 6, and two spots between veins 3 and 5. Hind wing with hyaline 

 patches in and below cell and on inner area; an oblique macular band 

 beyond cell between veins 2 and 6; a small blue patch on discocellulars. 



Hab. Bouru. 



This species resembles E. bourica, Boisd., E. amboinica, 

 Hamps., and E. dubia, Rober, in the crimson bands being in- 

 complete dorsally ; it differs, however, from each of these species 

 in having a dorsal crimson patch on first segment, and no 

 abdominal blue bands. 



Euchromia fulgens, sp. nov.

 on remaining segments ; ventral and lateral crimson bands on third, 

 fourth, and fifth segments. Fore wing brilliant blue at base, and ex- 

 tending along veins beyond first hyaline spot ; a brilliant blue patch 

 on discocellulars ; hyaline spots below base of, and in and below cell ; 

 a spot above vein 6, and two spots between veins 3 and 5. Hind wing 

 with hyaline patches in and below cell, and on inner area ; a wide
