There are two species of Protoanthidhim 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 tibise 

 simulating the dilated tibiae of its model, and a Ohalcid, Megalo- 

 colus notator (Walk.) ; a Longicorn, Epania singaporensis (Pasc.) ; 

 a plume moth ; a Oapsid, a Reduviid, and an obscure Homopterous 

 insect ; two flies, Holocephcda near hirsiita (v. d. Wulp), and 

 Toxophora neeir javatia (Wied.). The resemblances between these 

 mimics and the Melipona are in some cases remarkably exact ; 

 the Longicorn and the Holocephcda 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 coloui'ed and 

 specially protected insect. Asterisks indicate the convergent 

 species which are probably synaposematic in the following dia- 

 grammatic arrangement represented in Table VII. (p. 271). The 

 whole of the species are shown in Plate XXIII. figs. 37 to 47.
