TAURIPHILA.—TRAMEA. 299 
3. Tauriphila argo. (Tab. IX. figg. 48, 49.) 
Tramea argo, Hagen, Stett. ent. Zeit. xxx. p. 263 (1869)’; Proc. Bost. Soc. Nat. Hist. xviii. p. 84 
(1875) °; Ris, Hamburg. Magalh. Sammelr., Odon. p. 33 (1904) °. 
Hagen’s very brief description! and the locality given” may possibly suffice for the recognition of this species, 
which is greatly helped by the character mentioned by Dr. Ris’. Hagen’s type is before me. Even 
when I first examined it in June, 1899, the appendages were broken and most of the wings lost. Enough 
remains, however, to verify the characters given on page 297; it may be added that the vertex, frons 
superiorly, and thoracic dorsum have a metallic-violet reflection, thorax and abdomen pale brown, a 
narrow mid-dorsal stripe on the carina and inter-alar regions of thorax pale yellow, caring and articulations 
of abdominal segments 5-9 blackish. 
All the specimens listed below appear to belong to one species, in spite of the following differences, most 
of which grade very gently into each other :—

The distal limit of the brown marking of the hind wing is the submedian cross-vein or the origin of A,,. 
The males from Guatemala and Rio Parana have the colours of the entire body darker and the yellow mid- 
dorsal thoracic stripe has disappeared ; they are evidently older individuals, that from Rio Parana having 
some traces of pruinosity on the ventral surface.
