Of P. nuhilus. Fall, {vide I. c. supra), Dr. Puton says {in litt.), 

 tlie distinct maculation of the membrane of the elytra, in comparison 

 with the obscure marking in P. geniculatus and P. ffracilicornis, is one 

 of the characters of the species always particularly noticeable.

Notus aureolus, Leth., Hem. Nord., 78, 7 (1874). 



TyjyJilocyba chlorophana, H.-Schf., F. G., 124, 9. 



Broad, upper surface pale greenish-jcUow. 



Head transverse, longest in the middle, rounded in front, scarcely angulatc, in- 

 cluding the long, not projecting, eyes lunate, wider than the pronotum. Myes 

 concolorous with the head, but partly with a darker shade. Pronotum convex, in 

 front following the contour of the concave posterior margin of the head, posteriorly 

 deeply emarginate ; posterior angles obliquely truncate, disc in the middle slightly 

 infuscated. Sciitellum large, posteriorly distinctly acuminate. Elytra broad' 

 posteriorly broadly rounded ; membrane sub-hyaline, slightly infuscated ; nerves 

 straight, parallel, yellow, the second cell shorter than the others. Wings slightly 

 infuscated, sub-hyaline ; nerves strong, blackish, except at the base of the apical 

 furcation of the third, which is pale, as also is the transverse nervule connecting the 

 fork with the second nerve ; the said furcation at its commencement acutely angulate, 

 and then divergent to the intramarginal nerve. Legs yellow ; posterior tibiae out- 

 wardly with small black dots at the base of the dark spines ; claws of the tarsi 

 blackish. Abdomen above, black, the posterior margin of the segments, including 

 the genitalia, broadly yellow, under-side yeUow. Length, 1^ line. 



Found among heather {Callnna vulgaris), in August and Septem- 

 ber. The species, new to our fauna, was taken last autumn at Forres, 

 by Mr. G. Norman. 



In the Verh. z.-b. Ges.Wieu,XTi, 507, Fieber founded on this species 

 his genus Erythria, but the slight differences in the form of the head 

 and the neuration of the wings from his genus Notus (= Dicranoneura, 

 Hardy), doubtless induced him subsequently (Kat. Cicad., p. 14) to 

 merge it in the latter.
