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.

 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 Dall. Bartica, Br. Guiana. One specimen 

 onh'.

 black, otherwise apparently identical.

LYG^ID^. 



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. 

 Antennas dull fuscous with apex of 1st and 'Ad joints yel- 

 low Pronotum fuscous with the lateral margins, a cen- 

 tral carinate line and the margins of the transverse sulci
