AMICHORUS.—FLOHRIA. O91 
Antenne a little thickened externally, the four penultimate joints moderately trans- 
verse. Head quadrate, coarsely punctate, the punctuation absent from a large space 
on the anterior part; eye occupying fully one half of the length of the side. Thorax 
very shining, coarsely but sparingly punctate, the punctuation leaving very little trace 
of a smooth space along the middle. Elytra dull, indistinctly punctate. Hind body 
black, without the least trace of tomentum; sparingly punctate, each of the terminal 
two segments with a fascia of scanty white hairs at the extreme base. Breast with a 
scanty griseous pubescence. Legs black, tarsi rufescent. 
I have seen only a single example; it is a male, and has a broad, moderately deep 
notch on the last ventral plate; the hind margin of the preceding segment is also a 
little emarginate. |

Hab. Panama, Volcan de Chiriqui between 4000 and 6000 feet (Champion). 
Antenne much thickened externally, the terminal joint ferruginous, the penultimate 
joints strongly transverse. Head rather sparingly punctate, the punctuation absent 
from a space on the middle. Thorax with the sides evidently sinuate in front, punctate 
like the head, with a smooth space along the middle. Scutellum black, metallic on 
the middle, this part punctate. Elytra very distinctly punctate, of a beautiful metallic 
green colour, showing, according to the light, purple or golden reflections. Hind body 
shining, black, sparingly punctate, and with an extremely scanty flavescent pubescence ; 
the hind margin of the sixth segment broadly yellow, as well as the whole of the 
seventh and the terminal styles. Legs elongate and slender, tarsi piceous. 
Of this species also only one example has been found; it is a male, having a very 
slight emargination of the apical ventral plate. 
FLOHRIA. 
Corpus elongatum, subcylindricum; antenne breves, latissimse ; palpi breves, labiales crassi articulo ultimo

This curious insect is not at all closely related to any other known to me. There is 
no stigmatic membrane on the sides of the thorax ; the ligula is broad at the extremity 
and slightly emarginate. The mesosternum is much produced between the middle 
coxe, so that it has a very acute termination; its posterior portion is separated strongly 
from the anterior by a line curved in the middle but not angulated; the middle coxe 
are very nearly contiguous; the metasternum is elongate, and the coxal appendages (at
