SOME NEW INJURIOUS WEEVILS FROM ASIA. 



By Guy A. K. Marshall, D.Sc. 



(Plate XVII.) 



Among some insects recently sent for identification to the Imperial Bureau of 

 Entomology by Mr. T. Bainbrigge Eletcher, Imperial Entomologist for India, and 

 Dr. K. Dammerman, Government Entomologist for Java, there were four un- 

 described species of Curculionidae, all of which are recorded as attacking cultivated 

 plants, though the extent of the injury inflicted is not indicated. 



Subfamily Brachyderinae. 

 Genus Antinia, Pasc. 



Head with the eyes lateral, moderately convex and almost circular. Rostrum 

 separated from the forehead by a straight transverse impression, deflected, scarcely 

 curved, and the lower surface parallel with the upper in profile ; the epistome shiny and 

 prominent, the sides strongly carinate, forming an acute angle behind and each 

 bearing three (occasionally four) setae, the apical margin broadly sinuate and about 

 as long as one of the sides ; the mandibles smooth and shiny, with a strong apical 

 tooth and each bearing four setae, the scar rather prominent and sub-triangular ; 

 the mentum filling the buccal cavity, smooth, shiny and bare ; the edge of the 

 submentum with two long, obliquely raised setae ; the scrobes curving downwards 

 close in front of the eye, their upper edge obtusely angulate. Antennae moderately 

 stout and squamose, the scape cylindrical, rather abruptly clavate and reaching 

 the middle of the eye ; the funicle with the two basal joints short, 1 either longer 

 or shorter than 2, joints 3-6 subequal and bead-like, 7 broader ; the club short 

 and ovate, the first joint as long as the rest. Prothorax subcylindrical, truncate 

 at base and apex, without postocular lobes or vibrissae ; the dorsal outline only 

 slightly convex, the apex not lower than the base. Scutellum small or invisible. 

 Elytra ovate, narrow and separately rounded at the base, the shoulders very- 

 oblique and without any prominence, the dorsal outline strongly convex and much 

 higher than the prothorax, the tenth stria complete, and no posterior callus. Sternum 

 with the gular margin very shallow, the coxae in the middle of the prosternum ; 

 the mesepisternum meeting the base of the elytron ; the metepisternum almost 

 covered by the elytron and the episternal furrow complete, the metasternum 

 between the coxae as long as the mid coxae and without any antecoxal fold, 

 the hind coxae touching the elytra. Venter with the intercoxal process obtusely 

 angulated and as broad as the coxa, segment 2 a little longer than 3 or 4, but shorter 

 than both together, the first segmental incision straight and deep. Legs : trochanters 

 without the usual elongate seta ; femora only slightly clavate, unarmed, the bind 

 pair hardly reaching the apex of the elytra ; tibiae cylindrical, with a strong apical 

 mucro, the anterior pairs slightly curved, the hind corbels broadly enclosed and partly 

 squamose ; the tarsal claws connate at the base.
