S. ementitor, sp. nov. (Mas.) Sat late ovalis ; sat nitidus ; pube 
albida vestitus ; niger, capite prothorace (vitta mediana lata 
excepta) antennis palpis pedibusque anticis pallide flavis, 
abdomine (parte mediana basali excepta) tarsisque testaceo- 
brunneis; capite sat crebre minus subtiliter, prothorace 
crebre minus subtiliter, elytris crebre dupliciter (sc. subtiliter 
et subfortiter) punctulatis ; prosterno medio longitudinaliter 
depresso ; spatio depresso minus lato antice angustato 
utrinque subtiliter carinato ; elytrorum sutura haud carinata ; 
lamellis abdominalibus haud integris. 
Fem. capite et pedibus anticis (tarsis exceptis) obscuris. Long., 
12h; lat. SC vax). 
In my tabulation of Scymnus this species does not fall very 
naturally beside any there characterised ; it will stand under the 
heading “‘ HH. Puncturation of elytra much better defined” on 
p. 249, and is at once distinguishable from all the rest of that 
group by its prothorax black in the middle with the sides very 
broadly of a pale yellow color. It bears an extraordinary resem- 
blace to Platyomus lividigaster, Muls., from which it differs in 
generic characters and also in the less coarse puncturation of its 
elytra, &e.

by Mr. Cowley from the same place. 
S. Cowleyi, sp. nov. Sat late ovalis; valde convexus; sat 
nitidus; pube albida densa erecta vestitus; niger, capite 
prothorace elytrorum apice antennis palpis pedibus anticis 
(femoribus supra et subtus lineatim infuscatis) tarsis omni- 
bus abdomineque rufo-testaceis ; capite sparsius subtillissime, 
prothorace crebre subtilissime, elytris crebre sat subtiliter, 
punctulatis; prosterno medio longitudinaliter depresso ; 
spatio depresso sat lato antice acuminato utrinque sub. 
tilissime carinato; elytrorum sutura postice subtilissime 
carinata ; lamellis abdominalibus haud integris. Long., 13 
]. ; lat., 125 1. (vix). 
In my tabulation (vide supra) this species stands beside 
poonindiensis and Meyricki, differing from both inter alia by its 
strongly convex form (viewed from the side the height of its 
elytra is not much less than their length), its rufo-testaceous pro- 
thorax and the sharply defined limit of the testaceous apical part 
of its elytra which is like that of Platyomus Koebelei. The speci- 
mens before me are probably males and it is likely that the head 
and front legs of the female are darker in color.
