? 
Var. Thorax without spots; elytra greenish-black, the sides 
and apex rather broadly fulvous. 
Length 6 millim. 
Of rather short, broadly ovate and convex shape, the head with 
a few punctures near the eyes, the latter large, each as wide as the 
intermediate space, the vertex piceous, lower portion fulvous, 
frontal tubercles narrowly transverse; antenne extending to the 
middle of the elytra, fulvous, the third and fourth joints verynearly 
equal, following joints rather stout and not longer than the fourth ; 
thorax more than twice as broad as long, of equal width, the sides 
rounded anteriorly, straight at the base, anterior angles prominent 
with a small tooth, lateral sulci deep and broad, the surface 
impunctate, fulvous, with a short transverse black band or spot at 
each side; elytra narrowly margined, rather strongly punctured, 
fulvous, each with ten black spots, of which three are placed 
transversely at the base, three below these before the middle, two 
larger ones nearly connected below the middle, and two others well 
separated near the apex, there is also another obscure spot placed 
at the apex on the suture; under side and legs dark fulvous ; 
metatarsus of posterior legs very short, claw-joint strongly swollen. 
Hab.. Bolivia. 
T cannot identify this species with O. fenestrata Har., to which 
it is no doubt closely allied. Von Harold, who gives no details in 
regard to the shape of the thorax, describes his species as having 
black antenne and under side, as well as similarly coloured legs 
and the elytra with 9 spots only; the thorax also is said to have a 
single band, not two spots, and the third joint of the antenne to be 
distinctly shorter than the fourth: none of these details applies 
to the present insect. The variety, which at first sight entirely 
differs in coloration, agrees in every structural detail and also in 
the colour of the antenne and under side; there is also a widening 
of the fulvous band at the sides corresponding with the fulvous 
space which separates the spots as in the type, and the greenish- 
black colour likewise is the same in the spotted form, although 
which of the two may be looked upon as the type is optional. 
OEDIONYCHIS DUODECIMNOTATA (Clark, MS.), sp.n. (Plate XIV. 
sme, ht) : 
Testaceous, the terminal joints of the antennz black; the head 
and thorax with two black spots, closely punctured ; elytra very 
closely and strongly punctured, the basal margin and five spots on 
each elytron black ; under side black, legs testaceous. 
Length 10 millim. 
Head with a few deep punctures, flavous, shining, the vertex 
with two black spots, frontal tubercles bounded behind by a deep 
groove, labrum black; antennz slender, testaceous, the terminal 
six joints black; thorax with strongly produced anterior angles, 
the lateral margins feebly rounded, the dise broadly flattened at 
the sides, closely and distinctly punctured, testaceous, with a large 
black spot at each side; scutellum black; elytra very broad and
