 center of eye emargination, cheek, clypeus, mouth parts except usually 

 for female mandible, front half of tegula, front and middle coxae and 

 trochanters of male, apex of femora and basal 0.2 of tibiae, pale yellow 

 or ochraceous yellow. The face usually has a median subdorsal 

 elliptical brownish mark, often its upper lateral corner black, and 

 especially in females the clypeal fovea is usually brownish. Female 

 mandible pale brown. The frons is commonly entirely black and when 

 there is yellow in its lower lateral corner this is truncate rather than 

 tapered dorsally, and rarely reaches center of eye emargination. 

 Antenna tinged with brown below; back half of tegula ferruginous; 

 hind coxa entirely ferruginous or basally more or less fuscous, at least 

 its apical 0.2 ± always ferruginous; legs fulvoferruginous except as

 and usually apex of hind femur above, weakly infuscate.

 rinaeus funebris carinatus. 



In the absence of the type of Polyrhabdus cariniger, application of 

 the name has been decided on the basis of the original description. 

 This is rather detailed and indicates that very probably the present 

 form was Walsh's cariniger.
