PLATYDID^E. 185 



cinereous. Tarsi with white bands. Wings with the lines 

 diffuse, undulating, blackish, very indistinct ; exterior line with 

 elongated white points ; marginal points black. Fore-wings 

 with a white costal point near the base, with three white costal 

 sub-apical points, and with two intermediate large white costal 

 spots. Length of the body, eight lines; of the wings, seven- 

 teen lines." 



The female ( T. finipalpis, Walk.) is red-lead colour with 

 purplish fringes, and brown spots on the costa. 



IX. NOCTU^E DELTOIDES. 



This Division was formerly regarded by many authors (in- 

 cluding Guenee) as closely allied to the Pyrales^ but is now 

 usually included in the Noctua. The moths are slender- 

 bodied, resembling Pyrales or Tortrices in form, and have very 

 long palpi, clothed with smooth hair, and extending consider- 

 ably beyond the head ; or securiform and upcurved. The legs 

 are long and slender, and the tibiae are without spurs, though 

 some of the species are furnished with large expansile tufts of 

 hair on the legs. The wings are broad, and not dentated ; the 

 fore-wings are generally more or less triangular. The antennae 

 of the males are pectinated, dentated, and ciliated, or are 

 simple, with a knot-like expansion in the middle. The larvae 

 have from twelve to sixteen legs, and the moths fly by night, 

 though many of them are easily disturbed during the daytime. 



Guenee divides the Deltoides into three families, the Platydidce 

 Hypenidce, and Herminiidcz. To these we have added the 

 Aventiidcz, which Guenee regarded as a separate division of the 

 Lepidoptera. 



FAMILY PLATYDIDCE. 



This is a family including a small number of American and 

 East Indian species of comparatively large size, with ciliated or
