BuprestidaB. 



Chalcotcema vittata, n. sp. 



Valde elongata, postice attenuata, senea, supra fere nigra, nitida ; 

 thorace antice parutn angustato, guttis parvis punctulatis viridi- 

 aureis impresso, disco plaga lanceolatanotato ; olytriscostis qiiatuor 

 perparum elevatis, interstitiia guttarum auratarum scriebus nota- 

 tis, marginibus vitta lata impressis. 



Long. 18-21 lin. 



Closely allied to C. qjax, Saund., but mucli narrower, 

 more attenuated posteriorly, nearly black above, and with a 

 golden-green submarginal strijie on the elytra extending from 

 the shoulder to the apex. The thorax is of the same form 

 as that of G. ajax, but with the posterior angles not the least 

 prominent ; there is no impression within the posterior 

 angles, the surface being gently convex, with small dots or 

 irregular green marks scattered here and there, leaving the 

 greater part black ; in the middle of the disk is a narrow 

 lanceolate space more or less defined by some green punctured 

 lines. The elytra are evenly convex, smooth, with the 

 suture slightly raised ; each elytron has four scarcely notice- 

 able costfB, marked out by lines of fine punctures ; the first, 

 second, and third intervals have each a series of small golden- 

 green more or less elongate marks ; in the second inter- 

 stice there are generally two marks which are larger than the 

 others ; the sutural angle has a very small tooth ; and there 

 are three or four small teeth on the apical margin. The 

 underside of the insect is green, with golden reflections. The 

 punctures on the prosternal process have a tendency to form 

 a line in the middle. The metasternum has a few strong 

 punctures. The abdomen has numerous impressions filled 

 with pale yellowish pile, one at the side of each segment being 

 particularly conspicuous. The male has the fifth segment 

 deeply triangular, notched at its apex; the sixth segment 

 has all its apical portion concave and filled with yellowish 

 pile or cottony substance. The female has the fifth segment 

 slightly truncate at the extreme apex, with an elongate trian- 

 gular apical impression, which is filled with yellowish pile ; 

 the sixth segment is not visible.
