Anaxipha incompta (Walker). 



1869. Eneopt era incompta Walker, Catal. Derm. Salt. Brit. Mus., I, p. 67. 

 [Tapayos[Tapajos], Brazil.] 



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



We are identifying this specimen with Walker's species provision- 

 ally, or at least until we can ascertain more about the type of the 

 species, as the description is woefully inadequate. 



Anaxipha tibialis (Saussure). 



1897. Cyrtoxipha tibialis Saussure, Biol. Cent. Amer., Orth., I, p. 236, pL 

 XI, fig. 40. [Teapa, Tabasco, Mexico.] 



Para. (C. F. Baker.) Two males, three females. 



These specimens show no differences from the description of 

 tibialis and we see no alternative but to record them as that species, 

 although comparison with Mexican material is not at present possible. 

 The two male specimens show differences which demonstrate the 

 presence in males of this species of a broad and a narrow type of teg- 

 mina, and consequently of the tympanum, also in both sexes of re- 

 cessive and intensive types of coloration. In the former of these 

 color types the dark lateral bar is quite narrow, distinctly dorsad on 

 the lateral lobes, and on the tegmina pencils but the immediate 

 vicinity of the mediastine vein; in the intensive type the bar is broad 

 and covers all of the lateral lobes except the ventro-cephalic portion, 

 which is yellow, and on the tegmina suffuses a broad belt costad of 

 the mediastine vein. 



As we here imderstand the species it is not far removed from imi- 

 tator (Saussure), from which it differs in the narrower head and pro- 

 notum, slightly different shape of the cephalic tibiae and more re- 

 stricted, less solidly infuscate dark areas on the pronotum and teg- 

 mina. 

 Anaxipha paraensis n. sp. (PI. II, figs. 60-62.) 



Apparently related to A. tolteca (Saussure), described from eastern 

 Mexico, but chffering in the broadly rounded lateral shoulders of the 

 pronotum, and in the shorter and narrower tegmina, which have the 

 speculum more longitudinal. Doubtless other features of difference 

 exist which will become apparent on actual comparison of the two 

 forms. 



Type: cf ; Para, State of Para, Brazil. (C. F. Baker.) [Acad. 

 Nat. Sci. Phila., Type no. 5343.] 



Size relatively large, broad, tegmina well vaulted : surface of body 



well clothed with hairs, which are bristly on the head and pronotum. 



_Head trigonal in cephalic aspect, faintly deeper than broad: occiput 



moderately declivent to the inter-anteimal region, with numerous
