RUPPELLIOIDES. 
Ruppellioides, Alph. M. Edw. Ann. Soc. Entom. France (ser. 4) 
vu, p. 279, (1867). 
Resembles Ruppellia, but the sub-orbital lobe not united with the 
front of the carapace so as to exclude the external antennae from the 
orbit. Basal joimt of the external antenne greatly developed, and 
produced between the sub-orbital lobe and the front, and bearing at 
its extremity the flagellum, which is thus included within the orbit. 
24. Ruppellioides convexus. 
Ruppellioides convexus, Alph. M. Edw. Ann. Soc. Entom. France 
(ser. 4) vii, p. 279, (1867). 
Carapace wide, and very convex, strongly lobate in front, the lobes 
covered with granules. Antero-lateral margins divided into five but 
slightly prominent teeth, and directed forwards. Front biemarginate, 
consisting of four rounded teeth. Anterior legs strongly granulous.
