30. Exochus virgatifrons, new species 



Figures 189,q; 194,b 



Front wing 4.9 to 6.0 mm. long; combined face and clypeus about 

 1.18 as high as wide, moderately convex both horizontally and verti- 

 cally, in profile faintly flattened just above clypeus and the apical 

 part of clypeus more strongly incurved, their punctures coarse and 

 strong, subadjacent on face, sparse on clypeus; apical angle of inter- 

 antennal process about 105 degrees; median swelling of frons weak, 

 laterally only indistinctly differentiated; hind ocellus separated from 

 eye by about 0.45 its long diameter in both sexes; median half of 

 apical margin of clypeus weakly concave; mandible with sparse, 

 moderate-sized punctures, evenly tapered from its base of moderate 

 width to its rather narrow apex, its lower tooth small; cos tula repre- 

 sented by short stubs; second lateral area of propodeum with a few 

 hairs basally and often a very few apicolaterally, the rest bare; 

 areola bounded laterally by weak or obsolescent carinae; hind femur 

 about 2.60 as long as deep in male, about 2.40 as long as deep in 

 female; front spur of hind tibia about 3.3 as long as wide in male, 

 about 3.4 as long as wide in female; punctures of second abdominal 

 tergite of moderate size, strong, sublaterally separated by about 1.3 

 their diameter, medially absent or very sparse. 



Colored in general like Exochus rutilatus except that the pale 

 markings are a little more extensive. The following are definite 

 points of difference: Frons always with a complete and rather broad 

 ivory orbital border that is confluent with ivory mark at top of eye; 

 ivory mark on upper hind part of pronotum extending forward to 

 about the epomia; pronotum sometimes largely pale; disc of scutellum
