Face yellow. Crown pale yellow-brown, with the front margin narrowly, and 

 a middle line, yellow. Pronotum yellow-brown, broadly paler down the middle, the 

 sides rather broadly yellow. Scutellum pale brown, with a middle line and the apex 

 yellow. Elytra brownish blood-red or yellow-brown, the costal area -whitish-hyaline, 

 the membrane, a siibquadrate spot in the apex of the brachial area, and an oblong 

 spot in the apex of the suprabrachial area, fusco-hyaline ; veins of the corium, in 

 highly coloured examples, blood-red, those of the membrane yellowish. Abdomen 

 yellow, more or less tinged with red, breast and legs yellow, tlie claws and the spines 

 on the inner side of the front tibiae blackish. Male genitalia precisely similar to 

 those of 2\ Douglasi, mihi. Length, -4 mm. 



A few specimens of this interesting insect were taken in August 

 last by Mr. Edward Saunders on an old paling under sycamore trees 

 at Clandon, a place about five miles south of Woking. Its continental 

 distribution appears to be France, Germany, Switzerland, and Austria ; 

 and its food-plant beech. 



Both Prof. Then and Dr. Melichar speak of entirely yellow ex- 

 amples of this species, and the former has been good enough to send 

 me specimens of this form taken in company with normally-coloured 

 cruenta ; these are certainly T. Douglasi, mihi ; neither of these 

 authors mentions specimens which intergrade in point of colour between 

 that proper to T. Douglasi and normally-coloured examples of cruenta. 



TYPHLOCrSA CANDIDULA. 



Typhlocyha candidula, Kirschb., op. cit., 185, 18 ; Fieb., op. cit., 67 ; 

 Then, I. c. ; Melichar, op. ciL, 345, 5. 



Entirely white, dull, the membrane faintly tinged with fuscous. Front pairs of 

 tarsi more or less fuscous, all the claws blackish. Appendages of the oedeagus all 

 subterete and pointed, the upper (posterior) pair sinuate and divergent, like a pair 

 of ox-horns directed cephalad ; each of the lower (anterior) pair is divided at the 

 base into two narrow incurved arms, of which the inner is the shorter, the appear- 

 ance of the lower set might, in fact, be equally well described as four narrow pointed 

 convergent arms, of which the two inner ai*e the shorter. Length, 31 — 4 mm. 



This species has recently been found by Mr. W. West on white 

 poplars at Blackheath, Lewisham, Lee and, Brockley. Its continental 

 distribution appears to be France, Germany and Austria, and it is 

 recorded as found on Populus alba and canescens and Salix incana. 



In his original description Kirschbaum says " ^ letztes Bauch- 

 segment und genitalklapjyen wie hei * * rosce;'^ this is correct with regard 

 to our insect, but it not unfrequently happens that the armature of
