Paryphes splendidus Dist? Coroica Yungas, Bolivia, April, 1899. 
A very handsome species, the size and general picture of 
laetus but the color is a rich orange-red for the encircling 
band and the femora, while the general color is a lighter, 
more brilliant and metallic green. The band is narrower 
especially beneath. Length, 17 mm. Referred here with 
some doubt. 
Trachelium tesselatum Dist..Bartica, Br. Guiana. 
Cydamus adspersipes Stal, Bartica, Br. Guiana. 
Cydamus trispinosus De Geer. Bartica, Br. Guiana. 
Leptocorisa filiformis Fab. Bartica, Br. Guiana, May. Two 
specimens. 
Leptocorisa tipuloides Fab. Bartica, Br. Guiana. Two specimens 
Hyalymenus dentatus Fab. Bartica, Br. Guiana, May. One 
specimen. This, like the other members of the genus, has 
very well marked characters which appear from agree- 
ment with descriptions to be very constant. It is perhaps 
worthy of note that out of sixteen specimens received 
from this locality there are representatives of eight well 
marked species. 
Hyalymenus dubius Dali. Bartica, Br. Guiana. One specimen 
only. 
Hyalymenus gracilispinus Stal. Bartica, Br. Guiana. Two spec- 
imens June and August. 
Hyalymenus pulcher Stal. Bartica, Br. Guiana. Three speci- 
mens March, June and August, 1901. Two have hind legs 
entirely black. One specimen is lighter, hind tibiae only, 
black, otherwise apparently identical. 
Hyalymenus puncticeps Dali. Bartica, Br. Guiana. Two spec- 
imens, March and April. 
Hyalymenus sinuatis Fab. Bartica, Br. Guiana. Two specimens 
March and May. 
Hyalymenus tarsatus Fab. Bartica, Br. Guiana. Two specimens, 
March and May. 
Hyalymenus vespiformis Fab. Bartica, Br. Guiana. Three 
specimens, April and July. 
Jadera sanguinolenta Fab. Bartica, Br. Guiana. April and May 
LYGvEIDv^:. 
Lygaeus sulcatus n. sp. This species appears to be closely related 
to obsoletus Stal and interstinctus Distant, but cannot be 
referred to any of the variations of these species since there 
are differences in the plan of coloration. The pronotal 
sulci are deep, curved, and with prominent margins. 
Head ferruginous with a fuscous central stripe widest 
at occiput narrowing and becoming obscure on tylus. 
Antennae dull fuscous with apex of 1st and ,'ld joints yel- 
low Pronoium fuscous with the lateral margins, a cen- 
tral carinate line and the margins of the transverse sulci
