Phytophaga Malttyana. 49 



rounded and converging from base to apex, anterior angles 

 distinct, subacute ; basal margin truncate, obsoletely sinuate on 

 either side, medial lobe slightly produced, obtusely rounded ; 

 upper surface subcylindrical, finely but distinctly punctured, the 

 puncturing more crowded in front ; on either side the middle disc 

 is a large deep fovea; in front of the basal margin near the hinder 

 angle is an oblique depression ; on the basal half of the surface, 

 leaving a narrow fulvous line on the extreme hinder margin, is a 

 broad transverse black band, abbreviated on either side near the 

 lateral border, its medial portion anteriorly produced, the front 

 edge trisinuate on either side, middle deeply emarginate. Scutel- 

 luni forming an elongated triangle, the sides straight, the apex 

 subacute, shining black, the extreme apex obscure fulvous. 

 Elytra sinuate on the sides, narrowed posteriorly, surface rather 

 more coarsely punctured than the thorax, smooth and sliining ; 

 the black bands on the surface of each are broad and have their 

 edges irregularly sinuate. Body beneath covered with coarse 

 adpressed sericeous hairs ; abdomen closely punctured. 



Without being parallel, this species is much narrower and less 

 cylindrical than C. \'2.-macidata, Fabr., from which insect it may 

 also be known by the black head and scutellum, and the different 

 arrangement of the black markings on the thorax and elytra. I 

 have made the above description from a single specimen, a $ , 

 taken by Mr. Wallace in the Island of Timor ; it is probable that, 

 in a series of individuals, the markings would vary as in C. 12- 

 waculata, and the transverse bands on the elytra break up into 

 spots.
