diminishing and terminating upon the third 

 median nervule. There is an obscure ir- 

 regularly curved sub-basal transverse line 

 and a similar transverse limbal line which 

 runs from the costa beyond the middle 

 obliquely to the third median nervule about 

 its middle, and then sweeps inwardly with 

 three irregular scallops to about the middle 

 of the inner margin. The secondaries are 

 pale fulvous. On the under side, both the 

 primaries and the secondaries are pale ful- 

 vous with obscure and incomplete geminate 

 transverse limbal lines. The white spot at 

 the end of the cell on the upper surface re- 

 appears indistinctly upon the lower side. 



$. The markings in the female sex are 

 very much as in the male, with this difference 

 that the white discal spot in the primaries is 

 in all specimens before me, save one, replaced 

 by a dark brown spot. In one case, the 

 silvery-white scales reappear, but far more 

 indistinctly than in any male. Expanse $, 

 50 to 65 mm. ; J , 85 to 100 mm. 



I have over forty specimens of this species, 

 male and female, reared ex larva. I hope to 

 be able to give shortly an account of the life 

 history of the species. 



PINARIDAE. 



Gonometa, Walk. 



190. G. brotoessa, sp. nov. <J. Front, pec- 

 tus, and upper side of thorax rich maroon ; 

 upper side of abdomen uniformly steely-blue ; 

 lower side of thorax and abdomen ferruginous. 

 Primaries rich maroon with a silvery dot 

 encircled by black at the end of the cell; a 

 yellow subtriangular spot below the cell near 

 the base. On the middle of the wing there 

 are two obscure parallel zigzag blackish lines 

 running from the apex diagonally to the 

 middle of the inner margin. The secondaries 

 have the costa dusky-ferruginous; the re- 

 mainder bluish-black. On the under side, 

 the primaries are maroon, heavily clouded 



with blackish on the cell and middle area. 

 The secondaries are colored much as on the 

 upper side. 



? • The female has the body as the male, 

 but much larger. The upper side of the 

 abdomen is brilliant steel-blue with an 

 orange colored tuft of hairs at the anal ex- 

 tremity. Both primaries and secondaries on 

 the upper and lower sides are uniformly rich 

 maroon. Expanse <J , 65 mm; <j> , 95 to 

 100 mm. 



There is less disparity between the sexes 

 than is the case in some other species of the 

 genus. 



NOCTUIDAE. 

 Gigantoceras, gen. nov. 



Allied to Risoba, Moore. The palpi are 

 not as closely compressed as in that genus; 

 the second and third joints are longer, less 

 hairy, and more attenuated than in Risoba. 

 The antennae are very long. In Risoba they 

 are not quite equal in length to the costa of 

 the primaries; in Gigantoceras, they are from 

 fully one-half to twice as long again as the 

 costa of the primaries, and are directed for- 

 ward. They are minutely serrated at the 

 base. The legs are also relatively much 

 longer than in Risoba and not so hairy. The 

 tibiae of the third pair have a subterminal 

 and two minute terminal spurs: in Risoba 

 the spurs are prominent. The primaries are 

 relatively shorter and broader than in Risoba. 

 The neuration so far as I have been able to 

 ascertain does not differ from that of RN 

 Type G. solstiiialis, Holl. 



191. G. solstiiialis, sp. nov. $ . Antennae 

 one-half longer than the costa of the prim- 

 aries, very slender; palpi and front fuscous; 

 collar brown ; patagia and upper side of thorax 

 white; lower side of thorax ami entire abdo- 

 men fuscous. The primaries are obscure 

 fuscous with a dark brown apical patch, and 

 the base and inner margin prevail
