152 MAHAKAMIA KAMPMEINERTI. 



No doubt Drury's Curcidio lotigipes ') {Macrocheirus Dniryi 

 Guér.) from the island of Johanna, one of the Comoro islands, 

 belongs to the genus Mahakamia. The figure given by Drury 

 /. c. shows very clearly most of its characters, even that of 

 the not widened penultimate tarsal joint. 



The following key may be useful to determine the 

 genera of this group of Curculionidae. 



a. Elytra distinctly narrowing backward. 



h. Anterior coxae rather widely separated. 



c. Joints of the funiculus slender, its second joint much 

 longer than the first. Rostrum curved. Scutellum 

 elongate lanceolate. Metasternum strongly convex. 

 Anterior legs in the cf very elongate. 

 * Elytra conjointly emarginate at the end. — cf . 

 Anterior femora and tibiae more or less waved, 

 the latter fringed with long hairs at the under- 

 margin of their apical half. Intermediate femora not 

 notched at the end. Penultimate joint of the tarsi 

 broad, subcircular. Pygidium declivous, not elongate. 

 Macrocheirus Schönh. 



** Elytra conjointly truncate at the end. — cf . Ante- 

 rior femora straight, anterior tibiae regularly faintly 

 curved, not fringed but provided all along their 

 underside with rows of minute tubercles separated 

 by a narrow well-defined furrow. Intermediate femora 

 with a regularly rounded notch at the end. Penul- 

 timate joint of the tarsi not broader than the pre- 

 ceding one. Pygidium horizontally stretched, narrow 

 and elongate. Maiiakamia, n. g. 



cc. Joints of the funiculus not or but little longer than 

 broad, its first and second joint about equal in length 

 to each other. Ro'strum straight. Scutellum acutely tri- 

 angular with concave sides. Metasternum not strongly 

 convex. — cf . Anterior tibiae fringed with long 

 hairs all along their undermargin.
