Long. 2f lin. 



C. elongate, subparallel, subdepressed above, pale fulvous ; the scu- 

 tellum black ; thi-ee vittee on the thorax nigro-seneous ; the elytra 

 bright metallic green, a sutiu'al line in front, the lateral border, 

 a broad vitta on the disc, flexuoiis near its apex, extending from 

 the base (where it is confluent with the sutiu-al line) nearly the 

 whole length of the elytra, and an apical patch, pale fulvous. 

 Head smooth, impressed on the vertex with a shallow fovea ; eyes 

 piceous ; second joint of antennas one-haK longer than the first 

 (the rest wanting)*. Thorax as broad at the base as long, siib- 

 conic ; sides naiTowly margined, sinuate behind, indistinctly 

 angled behind their middle, subsinuate in front, anterior angles 

 produced obliquely into a short, stout, obtuse tooth ; above convex, 

 transversely grooved at the base, coai'sely punctured ; a narrow 

 longitudinal Kne and the lateral border nigro-eeneous. SeuteUum 

 black. Elytra broader than the thorax, slightly broader behind ; 

 sides margined, posterior angles armed with a broad, flattened, acute 

 spine ; apex (Tab. IX. fig. 26) rounded, apical margin produced 

 into a flattened acute tooth, its outer edge with one or more indi- 

 stinct teeth ; above subdepressed along the back, convex on the 

 sides ; shoulders subprominent, slightly produced laterally, their 

 apex obtuse ; surface deeply and regularly pimctate-striatc, alter- 

 nate interstices raised, the two intermediate more strongly elevated, 

 costate ; bright metallic green, each elytron with its lateral border, 

 the suture in front, an apical patch, and a broad vitta on the disc, 

 pale fulvous ; the latter, which commences at the extreme base, 

 where it is confluent Avith the sutural line, nms obliquely down 

 the inner disc and joins the sutm'e at the termination of its second 

 third, it then curves obliquely outwards nearly to the base of the 

 posterior spine, from whence it is produced almost directly across 

 the elytron to unite A^ith the suture near its apex. Beneath pale 



* The antennae in the only specimen that I have seen of tliis insect are unfor- 

 tunately wanting, but from its liabit I have placed it in the present section.
