Halesidota Californica. 



Mas et fcem. Pallide ochracea; alee anticce fasciis sex obscuriori- 

 bus obliquis angulosis, 4a daque fusco marginatis el notatis, 

 6a e annulis devils; postica pallide citrina. 



Male and female. Pale ochraceous, paler beneath. Antennae 

 rather broadly pectinated in the male, setose in the female. Fore 

 wings with six irregular oblique zigzag slightly darker bands, which 

 have brownish borders; fourth and fifth bands brownish on the 

 interior border, and with a brown mark on each near the costa; 

 sixth composed of irregular ringlets. Hind wings pale lemon- 

 colour. Length of the body 8—8J lines; of the wings 23 — 24 

 lines. 



The uninterrupted pale bands on the fore wings of this species 

 distinguish it from H.fulvoflava, to which it is most nearly allied.

Halesidota breviuscula. 



Mas. Fusca; antenna pectinate; abdomen luteum, dimidio 

 basali piloso plaga fusca, fasciis poslerioribus nigris ; alee 

 anticce punclo discali fiavo ; postica? albidce, fusco marginatce, 

 apud marginem interiorem lutescente pilosce. 



Male. Brown. Palpi rising nearly as high as the vertex ; 

 third joint conical, minute. Antennae moderately pectinated. Ab- 

 domen luteous, extending much beyond the hind wings, very pilose 

 towards the base ; a patch of brown hairs commencing near the 

 base, and extending beyond the middle, and succeeded by abbre- 

 viated black bands. Fore wings with a pale yellow point near the 

 end of the discal areolet. Hind wings whitish, bordered with brown, 

 clothed with pale luteous hairs along the interior border. Length of
