SERRICORNIA. 
Buprestide. 
Ptosima magnifica, sp. nov. 
P. elongata, parallela, nitida, leete ochracea, nigro- vel ceruleo-viridi 
ornata ; elytris ad apicem truncatis serratis. Long. 73 lin., lat. 
21 lin. 
Form of P. 11-maculata, Hbst., but relatively longer, and 
with the thorax less ample, &c. Head bright orange-yellow, 
thickly and strongly punctured, with the neck, a spot on the 
crown, and two spots on the forehead blackish. Thorax one 
quarter broader than long, very slightly narrowed in front, 
gently convex, but flattened posteriorly, moderately and not 
very strongly punctured on the disk, closely and strongly 
punctured towards the sides; orange-yellow, with a broad 
sutural stripe and one on each side of it blackish. Scutellum 
eneous, shining. Elytra the same width as the thorax, and 
less than three times as long, attenuated towards the apex, 
strongly punctate-striate, the interstices with a row of punctures 
not placed very close together; orange-yellow, the suture, the 
apex, and a transverse band immediately before it, a longi- 
tudinal stripe from the shoulder reaching to the middle of each 
elytron, a spot on the suture behind the middle, and two spots 
on the margin bluish green. Apex of the elytra truncate, the 
sides towards the apex and the truncature serrated. Under- 
side of the body yellow, the various parts surrounded with 
bluish green. The mouth, antenne, and legs green; the 
femora marked with yellow. 
This species most nearly resembles Pt. amabilis, L. & G., 
but is at once distinguished by its larger size, by the thorax 
having three stripes, and by the apex of the elytra being 
serrated instead of having three strong teeth to each elytron.
