strongly convex. — cf. Anterior tibiae fringed with 

 long hairs all along their under margin. 

 * Elytra with a strong sutural spine at the end. — (ƒ. 

 Anterior legs very elongate, their femora strongly 

 curved near the base. The abdominal segments 

 simple. RoELOFSiA nov. gen. 



** Elytra with a very minute sutural spine. — cT . An- 

 terior legs but slightly elongate , their femora straight 

 or nearly so. The centre of the 1st, 2nd and last 

 abdominal segment provided with shallow impressions 

 which bear short bristles. Cyrtotrachblus Schönh. 



hh. Anterior coxae approximate. Otidognathus Lacord. 



aa. Elytra nearly parallel, conjointly truncate or hardly 

 emarginate at the end. Protoceriüs Schönh. 



The type of the genus Macroclieirus is M. praetor QjWi. 

 from Java^), and up to now two other species of this 

 genus have been described, viz. M. spectabilis Dohru (Stett. 

 Entom. Zeit. 1883. p. 362 and 397) from Nias and West 

 Sumatra, and the allied M. herveyi Waterh. (Ann. and 

 Mag. of Nat. Hist. (5) vol. XIX. 1887. p. 295) from 

 Malacca. — The specimen described by Dohrn as being 

 a male , no doubt belongs to the female sex according to 

 the furrow on the sides of the rostrum and the triangular 

 pygidium, whereas no mention is made of the two rows 

 of crenulations on the rostrum nor of the fringe of long 

 hairs on the under margin of the apical half of the front- 

 tibiae, which are very conspicuous characteristics of the 

 male sex. In the genus Macroclieirus the penultimate joint 

 of the tarsi is nearly circular (the sides strongly and regu- 

 larly rounded) , in Roelof sia and in Cyrtotracheliis it is 

 triangular (the sides straight). 



The type of the genus Roelof sia m. is Cyrtotrachelus 

 Buquetii Guér. from Bombay , and with this Cyrtotrachelus 

 dux Boh. from Assam is congeneric. The male of a third 



I) Perhaps Cureulio {Calandrd) longipes Drury, a species unknown to me, 

 will prove to belong likewise to this genus.
