66 Phytophaga Malayana. 



lata, utrinque abbreviata, prope medium posita, fulva ; tibi- 



arum apice tarsisque nigro-piceis. 

 Long. 1 g lin. 

 Hab, Penang. 



Head flat, labrum piceous, vertex smooth, nearly impunctate, 

 black, the black colour extending downwards along the inner 

 border of the eyes as far as the insertion of the antennae ; eyes 

 elongate, broadly but not very deeply notched ; first joint of 

 antennae incrassate, second short, ovate, third rather longer than 

 the second, cylindrical ; (in the single specimen before me, the 

 remaining joints are unfortunately wanting). Thorax nearly twice 

 as broad as long ; sides very obliquely rounded and converging 

 from base to apex, hinder angles produced backwards, acute ; 

 basal margin moderately concave on either side, medial lobe 

 scarcely produced, its apex broadly truncate, excavated to receive 

 the base of the scutellum ; above very convex in front, trans- 

 versely depresssd on either side just in front of the basal lobe ; 

 subcylindrical at the anterior margin ; surface smooth, impunctate, 

 the extreme basal and apical borders nigro-piceous, two large 

 subquadrate patches, placed transversely on the middle of the disc, 

 black. Scutellum subcordate, its apex obtuse, basal margin 

 deeply notched. Elytra feebly lobed at the base, slightly thick- 

 ened around the scutellum ; each elytron with eleven rows of 

 distinct punctures, which become nearly obsolete towards their 

 apex, interspaces plane, impressed each with an irregular row of 

 very minute punctures ; the broad yellow band is abbreviated 

 near the suture, and on the extreme lateral margin. Body be- 

 neath sparingly clothed with very fine pubescence. Anal segment 

 of abdomen with a large concave fovea. Pygidium finely but not 

 closely punctured. 



In the only specimen that I have seen of this species both an- 

 tennae are almost entirely wanting ; I cannot, therefore, with cer- 

 tainty refer it to Melixanthus ; in habit and in the form of the 

 prosternura it agrees with the other species of the genus.
