25. Lygus buxtoni, sp. n. 



Allied to L. muiri Popp., but differs as follows : vertex without distinct 

 longitudinal depression, rostrum scarcely attaining hind margins of posterior 

 coxae ; length of second antennal segment not quite equal to three times the 

 length of first segment ; length of pronotum equal to more than half the width 

 of pronotum at base. 



Colour. — Yellowish-brown tinged with reddish ; base and apex of cuneus, 

 tip of embolium, sides of venter and thorax, and marks on apical half of femora 

 bright red ; antennae uniformly yellowish, segment II fuscous at tip, segment 

 III fuscous on apical fourth, segment IV fuscous ; tibia pale yellowish, spines 

 brown and without spots at base. Membrane rather unevenly shaded with 

 fuscous, a spot beyond tip of cuneus, central spot, and basal half of areoles 

 paler, veins dusky, cubitus paler about apex of larger areole. 



Structure. — Length 4-7 mm., width 2-5 mm. ; short oval in outline. 

 Head : width 1-21 mm., vertex -38 mm. ; basal margin without elevated carina, 

 but margin formed by a rather deep step-down to the collum, which is normally 

 covered by the close-fitting collar ; position vertical, frons moderately convex, 

 eyes large, hollowed out behind and fitting closely against anterior angles of 

 the pronotum ; inner margins of eyes emarginate about insertion of antennae. 

 Rostrum, length 1-99 mm., scarcely attaining hind margins of posterior coxae, 

 Antennae : segment I, length -78 mm. ; II, 2-03 mm. ; III, 1'21 mm. ; IV, 

 •86 mm. Pronotum : length 1-12 mm., width at base 1-95 mm. Hind femur : 

 length 2-2 mm., width -52 mm., length of hind tibia 3-2 mm. Dorsal surface 

 clothed with pale yellowish pubescence, intermixed on clavus and corium with 

 a few golden, sericeous, pubescent hairs.
