This is a stink bug that I found in Indiranagar, Bangalore. It was dead at that time and had become stiff, so the following are the best pictures I could get. It is 2cms in length. I tried searching on the net on various websites but I didn't find a match for the colouration on the dorsal side. Also, I would like to know what those protrusions on the top half of the shield ( excuse me if 'shield' is the wrong terminology) are. They seemed to be quite a troublesome feature as none of the reference pictures I saw on the net seemed to have bugs with these 'protrusions' .
