LlBUE>'IA PALUnOSA. 



Delphax 2)aJudosa, Flor, E-hyn. Livl., ii, 82, 27. 

 Undeveloped form, ^ . 



Pale yellowish or brownish-yellow. Antennce : apex of the 1st 

 joint and base of the 2nd narrowly black. Elytra as long as the ab- 

 domen, slightly narrowed towards the long rounded apex. 



Head brownish, inclined to fuscous-brown. Crown with a somewhat fuscous shade 

 in front ; basal fovese distinct. Face : keels moderately acute and prominent. 

 AntenncB brownish-yellow ; 2nd joint at least one and a half times as long as 

 the 1st ; 1st joint at the apex, and 2nd at the base, narrowly black. 



l^horax — pr'onotum ycWow, with a distinct puncture on each side of the centre ; pos- 

 terior margin concave or somewhat angulate. Scutellum yellow. Elytra pale 

 yellowibli or brownish-yellow ; nerves somewhat thickly and finely punctured. 

 C'orium slightly tapering from the apex of the clavus to the long rounded apex. 

 Sternum yellow, or with a slight fuscous shade. Legs yellow ; 1st and 2nd pairs 

 with a brownish or fuscous shade. Tarsi : Ist and 2ud pairs black, or 1st and 

 2nd joints piccous and 3rd black ; 3rd pair, 3rd joint black. 



Abdomen: above, yellowish ; beneath, pitchy-brown ; genital processes brown, to- 

 wards the top reddish ; upper portion, when viewed from beneath, somewhat 

 square, with the upper margin concave. Length, 1 lino. 



By the shape of its genital processes, suggestive of L. neglecta, 

 but in that species the upper portion is much longer, entii-ely 

 brown, and attached to a shorter base. In L. i^ahulosa, when viewed 

 from beneath, they may be roughly likened to two flags blowing towards 

 each other. The different coloring of the antenna) and shape of the 

 elytra are also excellent diagnostic characters. 



Two ^ examples have been captured by Dr. Power at Mertou and 

 TVimbledon in June and July.
