PJatysoma Thugnaum, sp. n. 



Oblongo-ovatum, parum convexum, nigrum, nitidum ; frontc im- 

 pressa, stria integra ; pronoto (basi excepta) impunctato ; elytris 

 striis 1-4 integris, 5 ultra medium abbreviata ; propygidio 

 pygidioque grossc punctatis, hoc utrinque profunde fovcoiato ;

L. ^-^ miU. 



Oblong-oval, convex above, black and shining ; the head 

 feebly punctulate, impressed anteriorly, stria complete and 

 nearly straight in front ; the thorax smooth, \v'\t\\ a row of 

 punctures on each side along the basal edge, scutellar fovea 

 extremely minute, marginal stria complete ; the elytra, striai 

 1-4 complete, 5 equidistant between the fourth stria and the 

 suture, it reaches beyond the middle and anteriorly turns very 

 slightly away from the suture, the sutural stria is wanting ; 

 the propygidium is transversely densely punctate, punctures 

 large and ocellate, but along the base there are only small 

 irregular points ; the pygidium is similarly punctate, with a 

 very conspicuous fovea on either side and a smooth posterior 

 rim ; the prosternum, the keel is narrow in the middle and 

 without striaj ; the mesosternum is widely sinuous anteriorly, 

 with a well-marked marginal stria; the anterior tibice are 

 5-deutate, the two apical teeth are a little separated from the 

 third. 



This very distinct species may be placed near P. integrum^
