12. Antichira Desmarestii, n. s. 
Oblonga, parallela, niger, nitidissima; thoracis an- 
gulis anticis sat crebre subtiliter punctulatis, angulis 
posticis flavis, pygidio subtiliter striolato. Long. 83 lin. 
Very close to A. variabilis, Burm. Burmeister places 
this species in a different section from his A. trifida; 
but as both species vary very much in colour, it is 
extremely difficult to distinguish them, except by the 
sternal process, which in A. trifida is rather thick, and 
not very much enlarged at the apex, whilst A. variabilis 
has this process slender, more curved, and clavate at the 
apex. The form which I now propose to call A. Des- 
marestii is nearest to A. trifida, but has the sternal 
process more slender and more acuminate at the apex. 
One male example has the pygidium margined at the 
apex with dull yellow; the female has a yellow spot on 
each side ; a female example from New Grenada has the 
pygidium black. 
Hab. Ecuador (Buckley) ; New Grenada. 
B. Scutellum never more than one-third the length 
of the elytra, often shorter; the other characters as in 
Section A. Species 13—17. 
13. Antichira polita, n. s. 
Oblonga, convexa, nitidissima, viridi-gnea, cuprascens ; 
elytris striis levissime impressis atque subtilissime 
punctulatis, scutello parvo. Long. 11 lin. 
Closely resembles A. lucens in general form and 
appearance, and might be mistaken for it, except for the 
small scutellum, which only measures four millimetres 
in length. Front of the head and the clypeus closely 
and rather strongly punctured. Thorax rather strongly 
rounded at the sides posteriorly, extremely delicately 
punctured, the punctures a little more close at the sides 
than on the disk; the base moderately sinuate on each 
side of the basal lobe, which is quite straight next the 
scutellum. Elytra to nearly the middle parallel, but 
then somewhat arcuately enlarged; smooth (or with 
only a few extremely delicate punctures) except at the 
apex, which is strongly punctured. The pygidium is
