454 MR. MARTIN JACOBY ON NEW SPECIES [Nov. 28, 



Var. Thorax without spots ; elytra greenish-black, the sides 

 and apex rather broadly fulvous. 



Length 6 inillim. 



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 ; antennae extending to the 

 middle of the elytra, fulvous, the third and fourth joints very nearly 

 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. 



Ilab. Bolivia. 



I cannot identify this species with O.fenestrata Har., to which 

 it is no doiibt closely allied. Yon Harold, who gives no details in 

 regard to the shape of the thorax, describes his species as having 

 black antennje and under side, as well as similai'ly 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 antennse 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 antennae 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. 



Oedion\'Chis duodecimnotata (Clark, MS.), sp. n. (Plate XIV. 

 fig. 11.) 



Testaceous, the terminal joints of the antennae black ; the head 

 and thorax with two black spots, closely punctured ; elyti'a very 

 closely and strongly punctured, the basal margin and five spots on 

 each elytron black ; under side black, legs testaceous. 



Leng-th 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 ; antennae slender, testaceous, the terminal 

 six joints black ; thorax with strongly produced anterior angles, 

 the lateral margins feebly rounded, the disc broadly flattened at 

 the sides, closely and distinctly punctured, testaceous, with a large 

 black spot at each side ; scutelium black ; elytra very broad and
