Zombrus flaviceps sp. n. — Rufous, the head yellow, the 

 antennae, tips of mandibles, pro- and mesothorax and legs, except 

 the hind coxœ, with their spines, the palpi and tips of mandibles, 

 black ; there is a flat spiniform small plate between the antennae ; 

 the upper coxal spine long, curved, narrow, the base dilated, the 

 rest narrowed, but not much, towards the apex ; the lower tooth 

 about one fourth of the length of the upper and stouter compared 

 with the length. Wings dark fuscous violaceous, the stigma and 

 nervures black, 9- 



Length 26 mill. 



Mayumbe (Cabra). 



Head, pro- and mesothorax smooth, the face covered with long 

 black hair. Pronotum coarsely longitudinally reticulated. Meta- 

 notum somewhat strongly reticulated and punctured, the sides 

 more or less transversely striated. Mesosternal furrow closely cre- 

 nulated; the furrow at the apex of the mesopleuras more strongly 

 so. There is a triangular space on the upper, basai half of the meta- 

 pleurae, its base smooth, the apex fmely punctured; the rest 

 closely, strongly, slightly obliquely striated. Abdomen strongly 

 striated, the striœ becoming gradually weaker towards the apex ; 

 the area on 2 nd segment large, its basai half gradually, roundly 

 narrowed to a bluntly rounded point, the apex with the sides 

 rounded ; its narrowed basai half bounded by stout, oblique, 

 clearly separated punctures; the sides of the segment are finely 

 irregularly punctured and bear some stria?; the transverse sutures 

 are closely crenulated. The centre of the basai slope of the l n abdo- 

 minal segment is bounded by stout keels, which run on to the 

 middle of the segment. Tibia? and tarsi densely pilose; the apices of 

 the tarsal joints spinose. 



The apical abdominal segments are absent but the spécimen 

 seems to be a $.
