species shows no features of difference from the Linnean description 

 which might not be due to discoloration of the original material. 



Anaxipha cayennensis (Saussure). 



1897. Cyrtoxiphus aztecus var. cayennensis Saussure, Biol. Cent.-Amer.", 

 Orth., I, p. 235. [Cayenne.] 



Igarape-assu. (H. S. Parish.) Two males. 



We have used for comparison material from British Guiana, and 

 found some slight differences, chiefly in the relative width of the 

 dorsal field of the tegmina, but nothing sufficiently marked or con- 

 stant to make it advisable to separate the two lots. Saussure 

 considered this merely a variety of azieca, but we prefer to give the 

 name specific rank until more is known concerning its relationship 

 to azteca, in this following Chopard and Bruner. The former author 

 has recorded the species from Nouveau-Chantier, French Guiana; 

 the latter from Santarem, Brazil. Our material is of similar small 

 size to that reported by Bruner.^-' 



Anaxipha nitida (Chopard). 



1912. C[yrto.ripha] nitida Chopard, Ann. Soc. Entom. France, LXXXI, 

 p. 408, 4 figs. [Xouveau-Chantier, French Guiana.] 



Para. (C. F. Baker.) One female. 



This individual is fully typical of the present striking and beautiful 



species, although slightly smaller than the original measurements. 



The antennae are broadly white annulate on a fuscous ground, at 



a point about three millimeters from their bases. The coloration 



of the antennae is not mentioned in the original description. 

 Anaxipha variegata (Chopard). 



1912. C[yrtoxipha] variegata Chopard, Ann. Soc. Entom. France, LXXXI, 

 p. 407, 4 figs. [St. Laurent and Nouveau-Chantier, French Guiana.] 



Para. (C. F. Baker.) One male. 



This specimen may prove to be distinct from true variegata, as it 

 shows certain color features not mentioned by Chopard, but, at pres- 

 ent, we prefer to consider these individuals variations or the color 

 features to have been omitted from the description by Chopard. 

 The antennae are solid blackish proximad, then follows a broad cream- 

 colored area, which contains two narrow broAvn annuli, distad of this 

 the color is pale brownish with regularly placed dark brown annuli. 

 The occiput is pale yellow, caudad broadly blackish brown, like the 

 face and between the eyes, in the middle of the yellow area is a trans- 

 verse bar of blackish brown. The median femora, like the cephalic 

 ones, have a distal pale area colored like the tibiae, and in addition a 

 median annulus of the same.
