1882. | SPECIES OF PHYTOPHAGOUS COLEOPTERA. 53 
thickened; second a little shorter than the third ; seventh and eighth 
joints gradually widened ; last three joints flattened, broader than 
long, black. Thorax narrowly transverse, fulvous, shining ; sides 
rounded, anterior margin straight; disk rather convex, closely and 
deeply punctured. Scutellum triangular, fulvous. Elytra wider at 
the base than the thorax, moderately convex, the sides deflexed ; 
surface closely and regularly punctate-striate, black, opaque, a trian- 
gular spot at the shoulder and a narrow elongate apical one fulvous, 
Underside and legs entirely fulvous. 
Three specimens are contained in my collebtion, 
Baya, noy. gen. 
Elongate, subparallel. Head perpendicular, broad, invisible from 
above. Eyes slightly emarginate, small. Palpi filiform. Antennee 
half the length cf the body; second joint short, globose; third 
and following three joints subequal, slender; the rest gradually 
thickened. Thorax transverse, its sides rounded and entire, anterior 
angles produced. Scutellum triangular. lytra slightly wider than 
the thorax, convex, semipunctate-striate. Legs of moderate size ; 
the intermediate and posterior tibiz of the male with a large tri- 
angular acute tooth. 
2. Intermediate tibize toothed oniy, the posterior ones emar- 
ginate ; prosternuin greatly narrowed in the middle, the base trun- 
cate; anterior thoracic episternum concave. 
Type, Balya quadrimaculata. 
I found this genus upon a handsome-coloured insect, of which 
three specimens are contained in my collection, from Brazil. It 
ought to be placed amongst the first group of the Eumolpide (the 
Iphimeine, according to Chapuis’s arrangement), from all genera of 
which it is easily distinguished by the toothed middle and posterior 
tibize of the male and its general elongate subcylindrical shape. 
5. BALYA QUADRIMACULATA, Sp. OY. 
Below black ; head, thorax, and the base of the femora fulvous ; 
antennee (the first 4 joints excepted), a spot at the middle of the 
thorax, and the tibia black ; elytra dark purplish, the suture and 
two spots on each elytron flavous. 
Length 3 lines. 
Hab. Brazil (Lagoa Santa). 
Head very finely and closely punctured, broad, the eyes very 
distant. Antennee black, the first four joints fulyous. Palpi fulvous, 
terminal joint black. Thorax transversely convex, not narrower at 
the apex than at the base, the anterior angles produced into a short 
tooth, fulvous, with a central black rhomboidal spot; surface 
scarcely visibly punctured. Scutellum black, triangular. Elytra 
slightly wider at the base than the thorax, parallel and subeylindri- 
cal; surface closely covered with large and smaller punctures arranged 
in subregular rows, the apex longitudinally costate ; of adark purplish- 
blue colour, the suture narrowly, and two irregular-shaped spots near
