darkly fuscous, the third and fourth joints being rufo-fuscous. Legs

 of Mr. Baly. 



Genus 9. PILffiDROMUS*. (Tab. III. fig. 1.) 



Labrttm transversum. 



Palpi maxillares : art. 2 nd0 ad basin attenuate, ad apicem dilatato et 

 oblique truncato, 3"° elongato et contracto, 4 t0 minuto. 



Palpi labiales elongati. 



Antennae Jili formes, sat robustm. 



Oculi globosi, ad latera capitis positi. 



Caput breve, haud antice productum. 



Thorax transversus, latus, ad latera angulatus, glaber. 



Elytra subparallela, depressa, elongata, ad apicem rotundata. 



Pedes : tarsis anterioribus latis, artic. 3 tio haud bijido ; femoribus 

 posticis incrassatis, tibiis ad apicem longihidinaliter marginatis, 

 tarsis attenuatis. 



Labrum transversely subcircular. 



Mandibles robust, short, with an inner obsolete tooth at their 

 inner margin, concealed. 



Maxillary palpi (Tab. III. fig. 1 m) : the basal joint obsolete, 

 obscure ; the second narrower at the base than the apex of the basal 

 joint, dilated and broadly truncate at the apex, the length being 

 more than twice the greatest breadth ; the third more elongate, and 

 narrower, subdilated towards the apex, and broadly truncate ; the 

 apical joint is minute, subconical, considerably smaller at the base 

 than the apex of the penultimate joint, the length equalling 11 of its 

 breadth. 



Labial palpi (Tab. III. fig. 1 n) corresponding in form to the 

 maxillary ; the second joint elongated, and gradually dilated towards 

 the apex ; the apical joint minute, smaller at the base than the apex 

 of the second joint, narrower and distinctly more elongate than the 

 ultimate maxillary joint. 



Antenna' filiform, sufficiently robust ; the basal joint elongate, in- 

 curved outwards, and gradually dilated towards the apex, the apex 

 broadly and transversely truncate ; the second much narrower than 

 the first, short, and ovate; the third shorter than the first and
