32. EXETASTES SUBIMPRESSUS, new species 



Similar in form of clypeus and slender abdomen as well as m many 

 other respects to ornatus, but immediately distinguishable by the 

 entirely black body in the female and the lack of yellow marldngs 

 dorsally in the male. 



Female. — Length 12 mm, antennae (broken). 



Head slightly broader than thorax, a little more than twice as 

 broad as thick medially; occiput rather deeply concave, temples 

 wealdy convex, strongly receding, sparsely and weakly punctate; 

 frons shallowly concave, rather densely punctate; face less than twice 

 as broad as long, densely punctate, roundly elevated medially, con- 

 cave laterally below antennae; clypeus narrower than face, weakly 

 convex in profile, divided into basal and apical portions only by 

 difference in sculpture; cheeks in front view short, their extended 

 angle slightly acute; malar space a little more than half basal width of 

 mandible; mouth as broad as face; junction of occipital and hypo- 

 stomal carinae distant from base of mandible by nearly the width of 

 latter; eyes rather strongly convex, slightly convergent below, longer 

 than superior width of face; postocellar and ocellocular lines equal 

 and each nearly twice as long as diameter of ocellus; antennae slender 

 (tips gone but undoubtedly attenuate apically and probably with 

 55-60 joints), first joint of flagellum hardly twice as long as second, 

 wliich is nearly three times as long as thick.
