TWO NEW BEITISH HEMIPTERA. 

 BY EDWARD SAUNDERS, E.L.S. 



Trapezonotus Ullrichii, Fieb., Weit. Beitr. z. Nat. u. Heilkunde, 

 p. 347, tab. ii (1836), fig. 23. 

 This species may be known at once from our other species of the genus by the 

 long basal joint of its posterior tarsi, which is twice as long as the other two 

 together. In colour and form it resembles a large agrestis, and has the tibise spinose 

 as in that species, but the antennse are more slender, the 3rd joint is proportionately 

 longer, and the 2nd and 3rd joints are testaceous ; the pronotum is longer in pro- 

 portion to its width, the puncturation of the elytra is finer, and the membrane is 

 pale whitish ; the apices of the femora and all the tibise are testaceous. The entire 

 insect is of a lighter and brighter colour. 



This important addition to our list was taken by tbe Eev. T. A. 

 Marshall " last summer on the cliffs near Boscastle or Tintagel, 

 Cornwall," who, recognising what he had captured, sent it to me for 

 Terification, and very generously made me a present of the specimen.

Somewhat intermediate between tenella, Zett., and coleoptrata, Fall. ; it re- 

 sembles the former in the $ sex in having the short rudimentary elytra, and re- 

 sembles the latter in the J in having the anterior angles of the pronotum simple or 

 nearly so, not dilated as in tenella. 



It is rather larger than tenella, and in the $ the antennae are longer, and the 

 apical joint is hardly longer than the 2nd, the chief character, however, lies in the 

 shape of the pronotum ; in this species the sides gradually converge to the anterior 

 margin, and are not dilated in front as in tenella, nor constricted into a short neck 

 as in coleoptrata ; the pronotum in front is narrower than the head across the eyes, 

 in tenella it is wider. The ? can only be confounded with that sex of tenella, from 

 which it may be known by its rather longer size, its duller surface, the more pu- 

 bescent and more closely punctured abdomen, the rather straighter sides of the 

 pronotum, and the shorter 3rd joint of the antennje. 



1 took 3 ^ and 2 ? by beating old lichen-covered larches near 

 Busbridge, Surrey, in July, 1890. I put them aside as probably dis- 

 tinct from tenella, and now feel little doubt that they are rightly 

 referred to the above species.
