REVISION" OF THE GENUS EXETASTES — CUSHMAN 277 



19. EXETASTES CALUPTERUS, new species 



Very similar in general appearance to bifenestratus , but much larger 

 with head and clypeus of different form, punctation of thorax coarser 

 and less dense, and differing also by many other characters. 



Female. — Length 15 mm, antennae 9 mm. 



Head much less than twice as broad as thick, the occiput deeply 

 concave, temples short but rather strongly convex, finely and rather 

 densely punctate; frons more closely punctate, broadly concave; face 

 rather flat with a low median elevation, less than twice as long as 

 broad; clypeus more than half as long as broad, much narrower than 

 face, distinctly emarginate at apex, basal portion weakly convex, 

 fully as long as apical portion, which is separated largely by difference 

 in sculpture; cheeks in front veiw nearly straight, their extended angle 

 nearly right; malar space slightlj^ more than half as long as basal width 

 of mandible; mouth much broader than face; mandible nearly twice 

 as long as broad at base, only slightly narrowing toward apex, lower 

 tooth larger and longer than upper; junction of occipital and hypost- 

 omal carinae fully three-fourths basal width of mandible from the 

 latter; eyes unusually long, nearly twice as long as broad, moderately 

 convex, distinctly longer than width of face, weakly convergent below; 

 postocellar line slightly shorter than ocellocular line and barely a half 

 longer than diameter of an ocellus; posterior ocelli touching posterior 

 tangent of eyes; antenna very short, slightly thickened in middle, 

 43-jointed, basal joint of flagellum fully twice as long as second, middle 

 joints as thick as long, subapical joints a little longer than thick. 



Thorax shining and rather densety and finely punctate, mesoscutum 

 more finely and very densely punctate, mat, with very short, very 

 dense erect pubescence, almost pilose; notauli lacking; scutellum 

 strongly convex, more coarsely and sparsely punctate than scutum; 

 propodeum confluently punctate, rugulose medially, positions of 

 pleural carinae indicated by difference in sculpture, spiracles rather 

 broad, far above normal position of pleural carinae. 



Legs rather slender, hind femur three-fourths as long as tibia ; inner 

 hind calcarium fully half as long as basitarsus; apical joint of hind 

 tarsus as long as third. 



Wings: Apical abscissa of radius nearly straight at base, more than 

 a half longer than basal abscissa; areolet rather small with long 

 petiole; second discoidal cell rather broad, second recurrent barely 

 two-thirds as long as basal abscissa of subdiscoideus, moderately 

 curved above; nervulus strongly postf ureal and strongly inclivous; 

 abscissula about twice as long as intercubitella. 



Abdomen moderatel}^ stout, first tergite a Httle less than twice as 

 long as broad at apex, second fully as long as broad at base; ovipositor 

 nearly straight, sheath distinctly shorter than first tergite.
