Genus (Edionychis, Erichs. 



11. OEdIONYCHIS aUADRIFASCIATA, Sp. nOV. 



Broadly ovate, black, above testaceous ; a transverse band on the 

 disk of the thorax, and four others across the elytra, metallic vio- 

 laceous blue. 



Length 4 lines. 



Head impunctate, deeply transversely impressed between the eyes, 

 shining, piceous, lower part of face flavous, apex of labrum piceous ; 

 antennae black, the first three joints flavous, stained with piceous 

 above, the first joint elongate, the third and fourth joints subequal. 

 Thorax very narrow, about four times as broad as long, its sides 

 broadly margined and evenly rounded ; anterior angles outwardly 

 produced, their apex rounded, basal margin sinuate on either side, 

 disk impunctate or scarcely visibly punctured, flavous testaceous ; a 

 black narrow band, not touching either side, extends transversely 

 across the disk ; scutellum black, smooth, broad, its sides rounded 

 and its apex obtuse. Elytra narrowed at the base and towards the 

 apex, finely but distinctly and moderately closely punctured, of a 

 testaceous colour ; a transverse hand at the base, one immediately 

 before, another behind the middle, as well as a fourth band near the 

 apex, metallic violaceous or greenish blue ; none of these bands 

 extend quite to the lateral margins ; and the intervals between them 

 are of about half the width of the bands themselves. Underside and 

 legs black, the margins of the abdominal segments obscure flavous ; 

 posterior thighs very thickened ; the first joint of the tarsi shorter 

 than the two following ones united ; the claw-joint very swollen.

 verse larger one in the middle, and another near the apex, fuscous. 



Length 2 lines. 



Head distinctly punctured, with a strongly-marked transverse 

 groove ; antennae with joints three and four of equal length, the first 

 five joints flavous, the rest piceous-coloured ; anterior angles of the 

 thorax toothed, the posterior margin nearly straight, surface im- 

 punctate, testaceous ; elytra narrowed at the base, rather flattened, 

 more convex behind the middle, distinctly punctured, the interstices 

 slightly wrinkled, of a flavous or testaceous colour, each elytron with 

 four fuscous spots, of which one (the smallest) is placed at the 

 humeral callus, another (larger one) near the scutellum, a more trans- 

 versely-shaped one at the middle, slightly hollowed out at its pos- 

 terior margin, and the fourth (generally the largest) also transversely 

 placed at a little distance from the apex. Underside obscure 

 piceous, the four anterior legs entirely flavous.
