but shorter and of a more oval form; the rugosities on the head 
are somewhat similar, but the lateral carinze do not unite behind. 
Thorax more quadrate ; the punctures more regular on the disk ; 
sides less rugose and rounded. Scutellum slightly larger. Elytra 
scarcely wider than the thorax; shoulders not enlarged; sides 
Jess attenuated behind, subparallel for about two-thirds of their 
entire length, then converging to the apex ; apical spines more 
obtuse than in the preceding species. Elytra scarcely twice as 
Jong as broad, the ground colour of the disk being lighter than in 
the preceding, and the golden spots do not show so brightly 
against it. Beneath similar ; prosternum trisulcate.

Lampetis affinis, n. sp. 
L. speciebus duabus precedentibus affinis. A ZL. psilopteroide 
differt mensura minore et humeris non prominentibus. A 
L. viridicupreé forma angustiore, capite minus rugoso, pro- 
sternoque bisulcato. 
Closely allied to the two preceding species, between which it 
almost forms a link. Smaller than Z. psilopteroides, from which 
it differs by the want of the prominent shoulders, by the much 
closer punctuation of the thorax, by the carine on the head not 
uniting at the vertex, and by the denser punctuation of the pro- 
sternum. From ZL. viridicuprea it differs by its narrower form, 
by the rugosities of the head being less strongly marked, and 
especially by its bisuleate prosternum.

Camboja, Pachbon. 
Obs. These three species are probably but varieties of one 
another; but having only a very few specimens, I have been obliged 
to keep them as species; they are very variable in punctuation, 
and probably more specimens would show similar modifications 
of form. 
Lampetis fastuosa, Fab. 
Var. B.—I have one specimen of a small narrow form of Lam- 
petis, which I believe to belong to this species ; it differs from the 
typical form in size only.
