There are two species of Protoanthidium coloured in the same way; and there is a large concourse of insects of different orders mimicking this type of coloration, viz.: four Hymenoptera; three species of Bracon, one with very hairy hind femora and tibiae simulating the dilated tibiae of its model, and a Chalcid, Megcdo-colus notator (Walk.); a Longicorn, Epania singaporensis (Pasc.); a plume moth ; a Gapsid, a Reduviid, and an obscure Homopterous insect; two flies, Holocephala near hirsuta (v. d. Wulp), and Toxophora near javana (Wied.). The resemblances between these mimics and the Melipona are in some cases remarkably exact; the Longicorn and the Holocephala were taken in the company of the bees; all the mimicking Hymenoptera are indistinguishable from their model whilst on the wing. In this group I consider the Melipona to be the central typical warningly coloured and specially protected insect. Asterisks indicate the convergent species which are probably synaposematic in the following diagrammatic arrangement represented in Table VII. (p. 271). The whole of the species are shown in Plate XXITI. figs. 37 to 47. |
