beyond the middle of the wing ; the marginal band is formed of quadrate, and 

 lunular, white or cream-coloured spots, — from the lower edge of the fourth, 

 fifth and sixth bluish streaks are projected into the tails, which are longer 

 and thicker than in mandarinus ; there are also some bluish marks, above 

 anal angle, along the inner edge of the black band. On the under surface 

 the discal cell of primaries is filled up with greyish and spotted with black ; 

 there is a wedge-shaped olive-brown blotch edged outwardly with black beyond 

 the cell ; and the olive-brown submarginal band is followed by a whitish one, 

 composed of lunular spots, each edged outwardly with blackish : the inner 

 edge of the marginal band of secondaries is more indented than in 

 mandarinus, and the blackish outer margin is bordered internally with 

 reddish and yellow ; the abdominal fold is speckled with black. Expanse, 

 88 mm. 



Two males taken at Wa-ssu-Kow in June, and one at Ni-tou 

 in May. 



DESCEIPTIONS OF SOME NEW SPECIES 

 OF PHYTOPHAGOUS COLEOPTERA FROM INDIA. 



By Martin Jacoby, F.E.S. 



Lema assamensis, n. sp. 



Black, impubescent, above rufous ; the thorax with two transverse de- 

 pressions, impunctate ; elytra with a deep sutural depression, finely 

 punctate-striate, the interstices slightly costate near the apex. Length, 

 3i— 4 lines. 



Head impunctate, the lateral grooves deep, the intermediate space 

 undivided ; labrum piceous ; antennae long, filiform, black : thorax scarcely 

 longer than broad, with an anterior and posterior transverse sulcation, the 

 latter not very deep, the siu'face entirely impunctate : elytra with a longi- 

 tudinal depression within the shoulders and a deeper subquadrate sutural one 

 below the base, the punctures very distinct but not deep at the base, gi-a- 

 dually diminishing posteriorly, the interstices near the lateral margins and 

 apex costate ; the under side, black, entirely glabrous, the last abdominal 

 segments margined more or less with dark fulvous ; legs black. 



Hah. Assam. 



This species, although closely allied to L. hamatomelas, Lac, 

 is larger than the latter, and the elytral depression is much 

 deeper ; the thorax is also somewhat longer ; from other simi- 

 larly coloured species the two thoracic depressions and black 

 under side will separate Tj. assamensis. (Coll. Jacoby). 



Lema nigkicollis, n. sp. 



Black, the head with two fulvous spots ; thorax impunctate ; elytra 

 fulvous, with a sutural depression below the base, finely punctate-striate, the 

 lateral margin thickened. Length, 3 lines. 



Head black ; the space between the eyes raised, fulvous, and divided by 

 a central groove ; antennae extending to half the length of the elytra, black ; 

 thorax subquadrate, deeply constricted at the middle, with a deep transverse 

 sulcation at some distance from the base, the surface entirely impunctate, 

 shining, black ; scutellum black, its apex truncate ; elytra fulvous, with a 

 sutural depression (less deep than in the preceding species) below the base, 

 the punctures resembling those of L. assamensis ; under side and legs black. 



Hah. Assam.
