towards the middle, black, still more finely punctured than the thorax, their epipleurae 

 very broad and concave ; posterior tibiae curved, mucronate, the first joint of the 

 posterior tarsi as long as the following three joints together. 



Hah. Celebes. 



Nearly allied to S. vlolaceipennis .Jac, but differing iu the colour of the antennae 

 and elytra, in the finely punctured thorax, and in the colour of the underside ; the 

 larger specimen has the abdomen partly piceous, and is of robust and broadly widened 

 shape. 



Sutrea sexmaculata sp. no\. 



Black, antennae fulvous, thorax and the four anterior tibiae flavous, elytra nearly 

 impunctate, black, two spots placed transversely at the middle and another, .semi- 

 lunate, near the apex, whitish. 



(?. The last abdominal segment with an elongate triangular impression. 



Length 2^ lines. 



Head impunctate, black, the frontal elevations in shape of two elongate raised 

 ridges, carina short, strongly raised, clypeus flattened, black, like the labrum, palpi 

 flavous, antennae entirely fulvous, third and fourth joints equal; thorax more than 

 twice as broad as long, the sides roimded, the anterior angles oliliijue, posterior ones 

 l>roduced outwards into a tooth, surface impunctate; scutellum broad; elytral 

 punctuation only visible under a strong lens, two small spots at the middle and a 

 semilunate transverse spot near the apex, yellowish white; breast, abdomen, and 

 posterior femora black, the last abdominal segment of the male with a long, triangular, 

 and deep excavation, extending the entire length of the segment. 



Hob. Andai and Humlioldt Bay, 



S. sexraaculata agrees in the pattern of the elytra with 5. hejxispUota Baly, but 

 differs in the fulvous antennae, the black head and underside, the scarcely perceptibly 

 punctured elytra, and in the male sexuah character, which differs from any other 

 species of Sutrea described, in the elongate shape of the sulcus of the medial lolie 

 of the last abdominal segment. 



Sutrea impressa sp. nov. 



Black, the basal joints of the antennae, the clypeus, and the anterior legs 

 testaceous, thorax whitish, with a central black patch, elytra finely and closely 

 ]>unctured, black, a transverse spot at the middle and a round one near the apex 

 white, the sides at the latter place with a longitudinal depression and a short costa. 



Length 2 to 2A lines. 



Head broad, the vertex black, impunctate, frontal tubercles transverse, yellowish 

 white like the clypeus, labrum black, antennae extending beyond the middle of the 

 elytra, obscure fulvous, the apical joints darker; thorax twice as broad as long, of 

 equal width, the sides almost straight, the anterior angles oblique, the surface very 

 minutely and not very closely pimctured, yellowish white, the middle with an ovate 

 or oblong black jiatch, pointed posteriorly, posterior angles not produced ; elytra 

 slightly depressed below the base, closely and very finely punctured in somewhat 

 regular rows, each elytron with a transverse spot at the middle not extending to 

 either margin, and a small round spot at the apex, whitish, the outer edge of this 

 apical spot is bounded by a short costa preceded by a longitudinal depression ; under- 

 side and the posterior femora black, legs obscure fulvous.
