SPHiERO DERMA

anterior lateral angles obliquely rounded, basal margin sinuate at 

 eacli side as usual, its median lobe broadly rounded and produced; 

 surface very minutely punctate, the punctures not very close 

 together, sparser in front. Scutellum triangular, smooth, im- 

 punctate. Elytra hardly broader at base than prothorax, punotate- 

 striate, each elytron having about eleven rows which are arranged 

 in pairs; a broad, so-called impunctate, space extends along the 

 lateral margin, and a row of deep punctures along the extreme 

 margin ; besides bearing the rows of punctures the whole surface 

 is completely and confusedly covered with very fine punctures. 

 Underside thinly covered with fine hairs. 

 Length, 4 mm. 



Burma : Toungoo (type-locality) ; Karen Mts. (Doherty). 

 Type in the British Museum. 



Jacoby first described this species in 1896, calling it flavo- 

 plagiata, but, finding that he had already used the same name 

 for a species of this genus from Sumatra, he changed it to omati- 

 pennis.

Brown; the seven apical segments of the antennae black; elytra 

 pale yellow-brown, the sutural and extreme lateral margins and 

 a large spot at the middle of each elytron, piceous ; the dark 

 sutural band is slightly widened at the middle ; scutellum piceous ; 

 epipleura brown, with the inner edge piceous. 



Head rather broad, impunctate ; clypeus broad, its apex straight. 

 Antennae extending to half the length of the body, third and 

 fourth segments more slender and equal. Prothorax nearly three 

 times as broad as long, sides scarcely rounded, anterior lateral 

 angles oblique, posterior margin slightly sinuate at each side, the 

 median lobe moderately produced; surface extremely finely 

 wrinkled, but this rugosity is only visible under a high power. 

 Elytra scarcely visibly punctate. 



Length, 3| mm. 



Tenasserim: Kawkareik [Kawkareet] (Fed); a single specimen. 

 Type in the Genoa Museum.

Upper side shining black; underside piceous, with the apex of 

 the abdomen brown ; legs reddish-brown ; the six or seven basal 

 segments of the antennae brown, sometimes tinged with piceous ;
