 part finely granular. Front and vertex closely punctured ; a distinct 

 median furrow from between base of antennae almost to the occiput; 

 space between the eyes at the top about equal to the length of antennal 

 joints three and four; third and fourth antennal joints about equal; 

 mesonotum closely, finely punctured, appearing almost granular; 

 scutellum not impressed, punctures separated and distinct; meso- 

 pleuraB granular, dull; dorsal aspect and sides of propodeum granular; 

 posterior face finely striated, with a distinct furrow which broadens
