204 [ February, i 



Taken on whitethorn {Cratcegus oxyncantha) at Lee, Dartford; c....^ 

 Addiugton Hills, from the end o£ June to the end of October. I 

 once found it on ajjple trees. 



Ttphloctba debilis, 11. sp. 



? . Pale yellowish-white. Head very obtusely produced, sides rounded, frong 

 with two large, round, black spots. Pronotum with a small black dot in front 

 close to the head, posterior margin scarcely concave. Scutellum concolorous with 

 the head and pronotum, the apex with a conspicuous shining black spot. Elytra 

 pale yellowish-white, with a delicate greenish flush, gradually deeper from the middle 

 of the corium to the outer margin of the clavus ; membrane pale fuscous, with in- 

 distinct pale yellowish nerves, generally the apex, and anterior and inferior margins 

 each, with a dark fuscous, inwardly directed, elongated spot ; on the corium, at the 

 base of the apical cells, a transverse row of fuscous spots. Wings diaphanous, lon- 

 gitudinal nerves yellowish, fuscous at the extremity. Legs pale, claws of the tarsi 

 fuscous. Abdomen above black, the margins of the segments white, the last ab- 

 dominal segment posteriorly broadly white, and roundly produced over the long 

 genital segment, which is whitish at the apex. Length, 1^ line. 



Close to T. tenerrima, H-Schf., but distinct by the black spots on 

 the head, pronotum, and scutellum, the absence of distinct vitta? on 

 the elytra, the fuscous membrane, &c. 



The male is unknown to me. I took three females at the Adding- 

 ton Hills on 26th October last, beaten out of blackthorn growing among 

 other bushes.
