 apically with large, sparse, shallow punctures, basally with fine, close punctures; 

 front with medium sized, close punctures; vertex with fine, close punctures; 

 interocular space at the vertex less than the length of antennal joints two and 

 three united; joints three and four subequal; mesoscutum with fine punctures, 

 well separated; mesoscutellum rather shiny, with sparse, fine punctures; epi- 

 sterna very densely punctate; disc of propodeum strongly striate, the striae 

 diverging from near the base; a shallow fovea at the apex; sides of propodeum
