1873.] 129 



Thorax : pronotum yellow or greenish-yellow, with a central, longitudinal keel, 

 terminating in a faint depression considerably before reaching the apex ; the 

 crenulation extends on either side in a diagonal manner from the base of the 

 central keel towards the posterior angles. Scuiellum brown ; apex, from the 

 ai'cuate channel, paler. Elytra pale brownish-yellow ; nerves brown* Clavus 

 with a few minute brown spots towards the apex. Coriuni, around the second 

 transverse nerves, thickly and minutely spotted with brown, the spots more or 

 less confluent ; the areas before the membrane paler than the other portion of 

 the disc, with numerous scattered brown spots ; immediately beyond the apex 

 of the clavus, the margin and a small portion of the disc, white, beyond which 

 is a dark brown patch nearly occupying the whole of the first membranal area ; 

 the remaining membranal areas yellowish-brown, with numerous minute brown 

 spots. Legs pale brownish ; tibice — denticidation in front black ; claios black. 



Abdomen above, black, margins of the segments narrowly pale brownish, beneath 

 yellow ; last genital segment above, pitchy-black, beneath yellow ; external 

 processes whitish, widened and flattened at the apex, and clothed wilh fine, 

 white hairs. Length, 2 lines. 



Allied to P. cet-ea, but the yellow or greenisli-yellow head and 

 pronotum will be found sufficient to separate the two species. 

 Apparently rare. Esher in June. 



Species 2. — Pediopsis ulmi, sp. n. 



(^ testaceous-brown ; ? fulvous or testaceous ; both sexes shining. 



(^ . Head and pronotum pale brownish-yellow. Scutelhmi with a 

 brown, triangular spot at the basal angles. Elytra deep testa- 

 ceous-brown, having a somewhat smoky appearance ; clavus — ■ 

 nerves stout ; tilice — 3rd pair black, spines pale yellowish or 

 whitish. 



Sead : face pale brown, around the ocelli and down the side margins frequently 

 darker ; ocelli minute, white. Antennce pale. 



Thorax ; pronotum pale brownish-yellow ; length down the middle about equal to 

 one-half the width ; crenulation finest next the centre ; posterior margin some- 

 what paler than the disc, and, in fresh examples, frequently with a faint 

 greenish appearance. Scutelhim more or less clear pale brown ; from the base 

 to the transverse channel finely crenulate-punctate ; basal angles with a large, 

 triangular, brown, unpunctured spot ; apex somewhat yellowish. Elytra deep 

 testaceous-brown, with a somewhat smoky appearance. Clavus — nerves stout, 

 dark brown or fuscous, the coloiu: extending on either side upon the disc, 

 thereby giving them a stouter appearance than they really possess. Coriiim — 

 anterior margin adjoining the nerve narrowly dark brown or fuscous ; Ist 

 longitudinal nerve entirely, and the two others, as far as the 2nd transverse 

 nerve, brownisli or fuscous, paler than those of the clavus, the colour extending 

 on to the disc as in the latter ; from the 2nd transverse nei-ve to the apex the
