 except that it is much narrower. Frontalia much narrower 

 than one parafrontal. Antennae short, third joint not over 

 three times the short second. Palpi rudimentary, very short 

 and slender, filiform. Cheeks about one-sixth of eye-height. 

 Proboscis corneous but not longer than head-height. Three
