testaceous band below the latter ; and the posterior half of the elytra 

 black. Entire underside and the femora rufous ; tibise and tarsi 

 black. 



82. DiABROTiCA ATRIVENTRIS, Sp. UOV. 



Oblong-ovate, widened behind. Flavous, shining ; antennae (the 

 first joint excepted), tibise and tarsi, abdomen, and the posterior 

 half of the elytra black. 



Ijength 3 lines. 



Head much longer than broad, longitudinally grooved in the 

 middle, impunctate. Antennae two thirds the length of the body, the 

 second joint half the length of the third, black ; basal joint fulvous. 

 Thorax transversely subquadrate, widened at the middle, surface 

 impressed with a deep transverse sinuate groove not extending to 

 the sides ; disk minutely punctured. Elytra closely and finely but 

 much more distinctly punctured than the thorax ; the anterior half 

 fulvous, the rest black ; breast and the femora fulvous ; abdomen, 

 tibiae, and tarsi black. 



The small size and the differences in colour will distinguish this 

 species from others nearly similarly coloured. 



Genus Cerotoma, Chevrol. 



83. Cerotoma trifasciata, sp. nov. 



Black ; head, legs, and thorax fulvous, the latter deeply sulcate, 

 with two piceous spots ; elytra costate, the intervals geminate-punc-

 and a third one near the apex bluish black. 



Length 4 lines.

 taceous, with a piceous mark ; antennae light testaceous, the basal 

 joint flavous. Thorax with a deep sinuate fovea in the middle of 

 the disk in shape of a W, and having a piceous spot at each end ; 

 surface with a few obsolete punctures near the anterior margin ; scu- 

 tellum fulvous. Elytra widened behind, each elytron with seven or 

 eight longitudinal costae, which do not quite extend to the apex ; 

 the interstices deeply geminate-punctate ; flavous, with three trans- 

 verse bluish-black bands, of which the last is the broadest and ex- 

 tends to the lateral margin, the others not quite reaching it ; under- 

 side black, the abdominal segments margined with fulvous, legs en- 

 tirely of that colour. 



This species is not unlike G. deyrollei, Baly, but is much larger, 

 and diff"ers in the colour of the underside and in the two spots of the 

 thorax.
