1908. 1 85 



strap-shaped, acuminate, bisinuate, ascending in their apical third, more than twice 

 as long as the app. inf. ; the latter lying in approximately the same horizontal 

 plane as the former, furcate from a short, base, the branches arcuate, pointed, 

 approaching at the tip, the outer one-third longer than the inner. ?: crown and 

 pronotum ivory-white, scutellum reddish-white, corium canary-yellow (chrome- 

 yellow), membrane not obviously fumose. 



T took this species off beech at Colesborne in October, 1895, and 

 bave not met with it since. 



LlVIA CREFELDENSTS, Mink. 



Distinguished from L. juncorum. by its paler color and much 

 smaller second joint to the antenna?, the latter being only sub-equal 

 in length to the second and third joints together. The food-plant of 

 this species appears to be unknown, but it is said to occur on grasses 

 in wet places. I have seen a pair taken by Mr. 0. Morley at 

 Tuddcnham, Suffolk 



PSTLLA VIBURNr, Low. 



An entirely p le species, greenish- or yellowish-white, with the 

 distal half of the last joint of the antennae black. Its food-plant 

 Viburnum lantana. on which it occurs in the perfect state in June, is 

 common in this district, but I have only found the insect on some 

 plants which grow amongst scrubby underwood on a dry hill-side ; 

 I have never found it on those growing in hedges. 



Trioza velutina, Forst. 



Scott (Trans. Ent. Soc. Lond., 1876, p. 555) treats this as the 

 same as T. galii, but this is a mistake, probably due to the fact that 

 he had never seen velutina. For many years past I have taken at 

 irregular intervals a few specimens of a Trioza which I regard as 

 T. galii, and whenever the shelter-plant could be noted it was always 

 Galium verum. On August 27th last, however, from some extensive 

 patches of Galium cruciatum growing just outside a wood here, I 

 swept up a number of specimens of a Trioza which agree well with 

 the description of T. velutina. The two species may be distinguished 

 as follows : — 



Elytra as a rule absolutely hyaline, nearly three times as long as broad, less sharply 

 pointed, the costa from behind the middle gently sloping towards the 



dorsum. Hind thighs entirely black galii. 



Elytra generally yellowish-hyaline, but little more than twice as long as broad, 

 attaining their greatest width near the middle and consequently more 

 sharply pointed, the costa from the middle abruptly sloping to the dorsum. 

 Hind thighs brownish-yellow at the apex velutina.
