SOME INJURIOUS INDIAN WEEVILS (CUECULIONIDAE)— II. 



By Guy A. K. Marshall, Hon. D.Sc. (Oxon.). 



Among some weevils forwarded for identification by Mr. T. Bainbrigge Fletcher, 

 Imperial Entomologist, Pusa, Bengal, certain species were indicated as causing 

 damage of economic importance ; of these the following six species proved to be 

 undescribed. 



Emperorrhinus, gen. nov.* 



Rostrum stout, longer than the head and continuous with it ; the mandibles very 

 unequal, the left being much the larger and projecting (when closed) considerably 

 beyond the genae ; in conformity with this, the left gena is also more developed and 

 . projects further beyond the scrobe than does the right one, the rounded apical excision 

 of the rostrum being therefore asymmetrical ; the scrobes dorsal and apical, short 

 and curving abruptly inwards, so that the space between them is scarcely half the 

 width of the forehead ; the process covering the condyle of the antenna convex, 

 testaceous and shiny, superficially appearing as though it might be the condyle itself ; 

 mentum small, subcircular and bearing a transverse row of four bristles. Antennae 

 long and slender, the scape curved and reaching the middle of the prothorax, the two 

 basal joints of the funicle elongate, the remainder longer than broad. Prothorax 

 truncate at the base, the anterior margin laterally sloping backwards from above 

 downwards ; the anterior coxae quite close to the front of the prosternum. Elytra 

 much broader than the prothorax and with prominent shoulders. Ahdoynen with 

 the intercoxal process ogival, segment 2 slightly longer than 3 and 4 and separated 

 from 1 by a deeply sinuate incision. Legs slender, all the femora with a single small 

 tooth, the corbels of the posterior tibiae open, the tarsal claws free. 



Genotype, Emperorrhinus pyricola, sp. n. 



This genus, which belongs to the group Phyllobiini, is nearly related to Myllocerus, 

 with which it agrees in most characters, but it should readily be distinguished by the 

 remarkable asymmetry of the rostrum, a character which I have never previously 

 observed in any adelognathous Curculionid. Other points which distinguish the 

 genus from Myllocerus are, the projection of the closed mandibles well beyond the 

 apices of the genae and the proximity of the front coxae to the anterior margin of the 

 prosternum.
