Vol. I] WILLIAMS— BUTTERFLIES AND HAWK-MOTHS 303 



in the Gulf of Guayaquil (Ecuador), and on St. Joseph Island 

 in the Bay of Panama, is interesting and suggestive. Sphingo- 

 notus fusco-irroratus (Orthoptera), is also reported from 

 Puna as well as the Galapagos Islands. 



25 specimens, including one S sent to Dr. Henry Skinner 

 for his opinion on the species.

HESPERIDAE 



6. Eudamus galapagensis n. sp. 



Male : Head brownish, with some yellowish-white scales which pre- 

 dominate ventrad ; Antennae strongly hooked, dark smoky brown, indis- 

 tinctly annulate with v/hite towards the base, hook of antennae tawtiy 

 below; labial palpi with distal joint dark brown; thorax greenish olive 

 with long hairs ; abdomen blackish with purple tinge and with pale yellow- 

 ish or yellowish-green scales, numerous ventrad and along the edge of the 

 segments. Legs brownish with purple reflections, and with long hairs of 

 lighter color. Length of body 16 mm. Above, — Wings dark brown with a 

 slight greenish-olive gloss and enclosing the small yellowish-white diaph- 

 anous spots arranged as follows : three small ones before apex, i. e., 

 one subquadrate at base of and on each side of Sc. i, the third which is 

 subtriangular, at base of SCs, and beyond the others ; two small rather 

 elongate ones, one on either side of the costal vein and situated at about 

 the middle of the wing. Immediately below these two is a larger spot in 

 the middle of the discal cell. Outwardly below in cell M2 is a still larger 

 subrectangular spot. This is the largest spot. In the outer third of cell 

 Ml is a square spot not extending half way down to the submedian nervure. 

 Inside the middle of cell Ms is a large rectangular spot exteriorly sinuate. 

 The three spots before the apex and those in cells Mi &3 are in line. 

 Fringes pale brown, brownish black from nervures. A fine double, 

 blackish brown line on edge of wings. Secondaries without spots ; with a 

 short slightly curved and tapering tail of a blackish brown color, its basal 

 hairs long and greenish. Under a lens, the nervures are largely metallic 

 purple. 



Below — The spots are repeated on the primaries. A rather obscure_ 

 lilac marginal band, becoming obsolete at anal angle ; a lilac patch with 

 some pale blue scales from the end of discal cell and in the discocellular 

 area. No markings on space overlapped by secondaries. Secondaries 

 blackish brown, with a basal, mesal, extradiscal and marginal band of lilac, 

 tinted with pale bluish scales, these bands reducing the ground to two 

 somewhat narrower bands and a spot near the base of the wing. The 

 extra-discal (=submarginal) lilac band is curved, especially where it 

 disappears at the tail where it becomes almost whitish. There are a 

 number of pale straw yellow scales on the secondaries, fewer on the 

 primaries. Expanse 43 mm., length of tails (exterior measurement) 

 6.25 mm. 



Female: Like the male, but with broader tails, 5 mm. long and about 

 straight, no costal fold on primaries, expanse— 46 mm. (Tagus Cove, 

 March-April, 1906).
