268 COLEMAN T. ROBINSON. 



This is a larger, broader species than T. vesperana, and the distinct- 

 ness of all the markings readily distinguish it.

Palpi, head and thorax dark fuscous above, the palpi pale testaceous 

 beneath. 



Anterior wings grey, irregularly clouded with fuscous, with a few 

 dark brown irroi*ations on costa at base, and along external margin. 

 Central fascia blackish-brown, distinct on costa ; indistinct, interrupted, 

 almost obsolete on and below the disc. Beyond, a blackish-brown, semi- 

 lunate costal spot. Fringes fuscous. 



Posterior wings shining fuscous; fringes whitish. 



Undersurface of anterior wings pale fuscous; of the posterior wings, 

 very pale testaceous.

Tortrix fumosa, n. s. (Plate iv, fig. 19, 9 •) 



Hend and thorax dusky ochreous. Palpi dull ochreous touched with 

 fuscous. Anterior wings dull oohreous. Basal patch indistinctly in- 

 dicated by an improminent smoky brown cloud on and above internal 

 margin at base. Central fascia smoky brown, indistinctly limited, more 

 or less interrupted on the disc spreading out broadly below to internal 

 margin. An elongated semilunate costal spot smoky brown. In some 

 specimens there are a few faint reticulations beyond the central ftiscia. 

 Fringes smoky brown, paler at internal angle.

Head and thorax dark fuscous ; palpi fuscous. Anterior wings dark 

 shining grey, with numerous brown patches and spots containing ag- 

 gregations of blackish scales. The usual pattern of ornamentation is 

 observable, but both basal patch and central fascia are very irregular 

 in outline and coalesce below the middle. Apical spot semilunate, dis- 

 tinct. Below its outer half an elongate brown patch stretches to anal 

 angle. This patch is filled in with blackish scales between the veins. 

 A row of brown spots containing central blackish scales beyond, along
