Athysanus punctatus n. sp. 



Superficially very strikingly resembling obtutus in form and color 

 but with a shorter head, large spots placed further apart and the ovi- 

 positor not exserted. Testaceous with two black spots on the vertex 

 just within the ocelli. Length, macropterous form, 3.5 mm.; bra- 

 chypterous form, 2.50-2.75 mm.; cj, 2.50 mm. 



Macropterous form : ?, vertex one-fourth wider than long, two- 

 fifths longer on middle than next the eye, sloping, rather roundingly 

 angled to the front. Front transversely convex, nearly parallel-mar- 

 gined to the antennae, then roundingly narrowed to the clypeus, cly- 

 peus about half longer than wide, suture indistinct, genae much longer 

 below angle than in obtutus. Pronotum four fifths wider than long, 

 strongly rounding in front, side margins very short, posterior margin 

 short, shallowly excavated, rounding to the long oblique humeral mar- 

 gin. Elytra twice longer than broad, overlapping at apex, apex nearly 

 truncate, the outer angle rounding, the base of the apical cells equal- 

 ling the tip of the pygofers. Venation weak and indistinct, appendix 

 short, four broad apical cells and one long costal one, under wings 

 fully developed. 



Brachypterous forin : ?, elytra .short and broad, reaching to the 

 sixth abdominal segment, their tips shortly rounding from both sides, 

 venation weak, the apical cells small and inconspicuous or wanting, 

 under wing reaching the third or fourth segment, pygofers armed with 

 a brush of stiff hairs. 



Color: Light testaceous, vertex a little more yellow with two large 

 round black spots on the anterior half, their diameter being about one- 

 third the width of the vertex; before and between these on top of the 

 vertex are two reddish-brown points. Eyes black, face and legs light 

 testaceous. Pronotum testaceous, scutellum with a yellowish cast. 

 Elytra sub-hyaline with a reddish metallic reflection, the black abdo- 

 men partly visible, ultimate dorsal segment broadly tipped with white, 

 penultimate one narrowly so, venter black. 



Genitalia: ?, ultimate ventral segment scarcely twice wider at 

 base than length on middle, the sides roundingly narrowing, posterior 

 margin broadly rounding, a flat elevated area in the middle. P) go- 

 fers rather small, scarcely inflated, oviduct very stout, little if at all 

 exceeding the pygofers. S\ valve broadly triangular, twice wider 

 than long, plates broad at base, regularly concavely narrowing to the 

 acute points, two and one-half times the length of the valve, pygofers
