give the diagnoses of the genera proposed by previous authors, as 



these will appear in their proper places in the more extended 



work. 



J Trochilium Pacificum. n. sp. 



Size and aspect of T. apiforvic, L. The forewings have a 

 blackish space at the base, and the borders and nervures of both 

 wings are orange brown, the same color as in the European 

 species. Antennae, rich brown, paler at the apex. Head, with 

 the front brown, orbits of the eyes and tibiae pale lemon yellow. 

 Palpi pale yellow. Fore femora and tibis pale yellow, bordered 

 inwardly with black. Hind tibiae and tarsi wholly yellow. Thorax 

 brown on the disk, with two stripes of yellow, broadest at the 

 base, and the tegulae edged broadly in front with yellow. There 

 is also a yellow spot at the base of the wings, leaving the tegulae 

 themselves brown. At the junction of the thorax and abdomen 

 are some black hairs, edged with yellow. The abdomen is wholly 

 blackish brown. Of the seven visible segments, the first is with- 

 out a band, the second has a very narrow golden yellow band in 

 front, the third a broad yellow band in front, sinuously notched 

 in the middle, leaving the centre narrower than the sides, the 

 fourth segment is without a band, the fifth, sixth and seventh are 

 wholly golden yellow, with a waved mark of brownish posteriorly 

 on the fifth and sixth. The anal segment is very long and taper- 

 ing. Sides of all the segments marked with golden yellow. 

 Underside of abdomen golden yellow for the last five segments. 



I i. Washington Ter. (Morrison), i ?. California, (R. H. 

 Stretch). 



Types. Coll. B. Neumoegen. J. Akhurst. 



The dark tegulae and the sinuous mark on the third abdom- 

 inal segment will serve to distinguish this species from T. api- 

 fornie L. of which it appears to be the Pacific Coast representative. 



EUHAGENA. n. gen. 



In many respects this genus is similar to Tarsa of Walker, 

 but it differs by the proboscis being short, instead of long, by the 

 antennae being much longer than the thorax, and by the fore and 

 hind wings being opaque. It may be thus characterized : Body 

 short at base, tapering posteriorly, with long anal tuft. Proboscis 

 short. Palpi densely clothed with long hairs, and nearly straight. 

 Antennae twice the length of the thorax, very deeply pectinated, 

 except at the tip, where the pectinations seem soldered together 

 into a compact mass. Legs long. Tibiae with long hairs, not so 

 long, however, as in either Melittia or Larimda. Tarsi naked. 

 Wings all opaque, the hind nearly double the width of the fore 

 pair. 



I have dedicated this singular genus to my good friend, Dr. 

 Herman Hagen, of Cambridge, one of the most distinguished of 

 living entomologists, and one to whom I am under special obliga- 

 tions.
