THE SPECIES OF SPHIDA GROTE 19 



and are curious in being black, with the last pair of spiracles directed 

 posteriorly like a dipterous larva. They come to land to pupate. I once 

 found one crawling in a dusty road in New Hampshire at some distance 

 from a swamp. 



Sphida oecogenes, new species. 



Of a reddish brown, without whitish shade at base of costa, though 

 that area is lighter than the rest of the wing, especially in males, and 

 somewhat pinkish ; no blackish shade beyond through the middle of the 

 wing, the shade being brown and not contrasted ; reniform wide, ellip- 

 tical, light red with brighter center, oblique, but not strongly so ; median 

 shade line fairly distinct ; outer line crenulate ; termen dark grajash fiUed. 

 Anal tuft of female white. Expemse, 30-35 mm. 



Cotypes, two males, four females. No. 1 5447, U. S. Nat. Mus. ; Wash- 

 ington, D. C, July 6, 1883; July 16, 1884 (Dept. Agr., Bur. Ent., 

 No. 2367). No collector's label is attached, but apparently all were 

 bred by Mr. A. Koebele. 



Sphida anoa, new species. 



Daxk reddish brown, the markings of fore wing obscured, essentially as 

 in (Ecogenes. Basal space a little lighter, followed by a red shade ; reni- 

 form elliptical, oblique, filled with dark red. Hind wing brown, the cell 

 pinkish, with a dusky discal mark. Expanse, 50 mm. 



Type, female. No. 15448, U. S. Nat. Mus.; Miami, Florida, 1901 

 (R. H. Hegen and H. C. Henricksen). 



Sphida gargantua, new species. 



Body parts gray ; center of thorax dark brown ; abdominal tuft of 

 female black. Fore wing with basal space violaceous gray, not white, 

 yet contrasted, followed by a dark brown shade ; reniform elliptical, 

 oblique, reddish filled ; orbicular a dot or absent ; outer line crenulate, 

 broken, faint ; termineJ space dark violaceous, contrasting, edged within 

 by a darker irregular line. Expanse, 45-55 mm. 



Cotypes, three females. No. 1 5449, U. S. Nat. Mus. ; Los Angeles, 

 California, May ; larva in Typha latifolia (D. W. Coquillett). 



Sphida pleostigma Dyar. 



This will be described in my forthcoming fourth Mexican paper to be 

 published in the Proceedings of the United States National Museum. It 

 is nearly allied to gargantua but apparently distinct.
