Yellow, deeply and irregularly punctured throughout. 
Head : crown somewhat elongate, the width along the posterior margin 
3z times greater than across the centre; sides slightly waved, apex 
rounded ; front plate as in alni. 
Phorax: pronotum, anterior margin slightly waved, apex acuminate. 
lytra yellow, with blach punctures, and without spots or patches.

The above are the giants of the Aphrophoride, and measure four 
lines in length. Of the two, alni is much the commoner. Both are 
widely distributed, and may be taken throughout the whole summer. 
Flor, in the Rhyn. Liv., ii, 187, 3, describes a third species, A. coriacea, 
Sahlb., said to occur on Pinus abies. It is smaller than either of the 
two other species, and is worth looking for. 
We now approach the Wembracina, or 4th Section (Jassida Mem- 
bracina, Stal, Hem. Afr., iv, 83), in the first family of which, Centrotide, 
we have two genera, each represented by a single species. These are 
Centrotus cornutus, L., known by its two lateral spines and one pos- 
terior spine, and Gargara geniste, Fab., in which the lateral spines 
are wanting. Both are so well known as to need no further notice 
here. In the 2nd family, Ulopide, we have again but one genus, 
Ulopa, which, until now, has only boasted of the commonest of the 
common among species, viz., obtecta, Fall. Not well adapted for 
leaping, the individuals cf this species lie lazily all the summer at the 
roots of heath, &c., the heat being too great for them to go abroad; and 
in winter are heaped up in numbers amongst the flowers and seed-pods 
which have fallen to the ground and are collected in little masses at 
the roots, and these they so resemble, that, until the insects move, you 
ean scarcely say which is which. As the genus Ulopa has but few 
representatives throughout the whole world, I consider the addition 
of the following species of more than ordinary interest. 
Genus 1.--ULOPA, Fall. 
Species 2.—ULopa TRIVIA. 
Ulopa trivia, Germ., F. Ins. Eur., fase. iv, tab. 21 (1812); Mag., 
iv, 56, 4 (1821) ; Burm., Gen. Ins, tab. 3 (18388). 
Pale yellowish-white. Blytra with three longitudinal black streaks. 
Head: crown black, thickly and deeply punctured, with a broad yellow streak down 
the middle and a narrow one adjoining each eye; anterior margin elliptic. 
Face black, with a yellow middle line. Antenne yellow. Eyes pale brownish. |
