visibly exposed; antennae 11-jointed, inserted in front of eyes at 



fore-margin of the forehead.

 porrect, and posteriorly nearly always constricted forming a neck; 

 the antennae inserted at fore-margin of forehead in front of eyes 

 inside of and above base of mandibles (Fig 110.et.al,)ll-jointed, 

 thickened outwardly or moniliform, rarely after a lon^ first joint 

 geniculate ( Acylophorus ) ; eyes occasionally very large (many species of 

 Quediu s) , oftenest normal, rarely small; mandibles robust, pointed, 

 often with teeth, when at rest folded crosswise; labrum oftenest 

 emarginate or cleft in middle, more rarely whole; first joint of 

 maxillary palpi small, the two middle ones stretched, distal joint

 the side; prosternum occasionally ( Xantholinina ) anteriorly expand- 

 ed into a movable plate, which covers the gula (gula-shield, gula-
