252. Crambus dividellus, nov. spec. 



Five specimens of 25 — 30 mm. expanse. 



This apparently undescribed species belongs to the section 0, d, 

 V, of Zeller's genus Crambus {' Chilonid. et Crambid. genera et 

 species,' p. 15), and is evidently allied to om' European tristellus 

 and selasellus ; from both it is distinguished — 1, by the bicolorous 

 fore wings (the costal half being ochreous yellow and the inner 

 ochreous brown) ; 2, by the want of the longitudinal white stripe, 

 which is always found in selasellus, and occurs in several varieties 

 of tristellus. Besides (and this is not the least considerable, 

 though not the most apparent difference), the front is rounded, 

 without the obtuse projection of selasellus and tristellus. Antennae 

 setaceous, nearly bare, brownish grey. Labial palpi thrice as long 

 as the head, brownish grey. Front and vertex pale ochreous 

 yellow. Thorax with collar and patagise ochreous brown. The 

 form of the fore wings is as in selasellus, the costa a little stronger, 

 and also more regularly rounded, without depression before the 

 more acute apex ; on the contrary, the hind margin is a Uttle more 

 sinuate. The costal half of fore wings is of a rather pure but pale 

 dull ochreous yellow, and the inner impure, greyish, dull ocJn-eous 

 brown ; the limit of the two colours is, however, neither sharp nor 

 quite straight ; on the bases of the veins 3 and 4 the brown 

 advances a Uttle towards the costa and beyond it retreats towards 

 the anal angle, leaving only the veins 3 and 4 brown. Besides, 

 towards the base of the wing, the ochreous yellow of the costal 

 half is sullied by ochreous grey-brown. In the fold a short ill- 

 defined ochreous yellow longitudinal stria is issued by the base ; it 

 does not reach the half of cell 1 b, and between its end and the 

 inner margin of discoidal cell we perceive a small ill-defined dark 

 grey spot ; marginal line marked with minute black spots. The 

 fringes have a silky lustre and are ochreous brown, with exception 

 of the basal half from the apex till veins 5 or 4, which is more or 

 less well-defined white. Hind wings white, a little glossy, dusted 

 with grey on the apical third. Fringes white. Under side of fore 

 wings grey, the apex and hind margin paler, first yellowish, 

 outwardly whitish. Hind wings as above. Abdomen grey, with
