Agonoscelis is a genus of shield bugs, in the monotypic tribe Agonoscelidini, that are native to the Afrotropics and Australia, but one species is established in the New World. Some species are minor[1] or considerable pests.[2]

They have five nymphal stages, and are 8 to 12 mm long as adults. They attack (or control) weeds and herbs including horehound, thyme, flax and cotton, or the developing seeds of sunflowers or cereals like millet or sorghum.[3] They may swarm on a variety of other shrubs and trees, including coffee and cacao.[2] The scent gland is located at the end of the abdomen.
