by the punctuation of the i-oi-iuni, wliicli i(< (.-lose and irregular all 

 over ; whereas, in claviculus, along the claval suture, there are two 

 regular sub-parallel rows of punctures, with a rather wide smooth 

 space between them, while the rest of the coriuni is closely punctured. 



LiTosoMA Douglas T, n. s. 

 Pale green ; elavus, outer nerve of the coriuni, and the external margin of the 

 cuneus, darker. Antenna; with a brownish tinge. After death, the head, the front 

 of the thorax, the legs, and the sides of the elytra more or less widely, become of a 

 yellowish-brown colour. Surface covered with short, curved, white hairs, mixed with 

 longer nearly straight black ones ; these black hairs ai-e only observable under a 

 strong lens. Membrane slightly clouded ; nerves pale greenish-yellow, yellowish- 

 brown after death. Tarsi brownish, black at the apex. Antennae : first joint about 

 two-thii'ds as long as fourth, second joint as long as third and fourth together, fourth 

 about — or not quite — two-thirds as long as the third. Length 2 lines.

Obs. — The short third and fourth joints of the antennae will at 

 once distinguish this species from its allies. I can find no description 

 of any European species to agree with it, and therefore describe it as 

 new. I have named it in honour of Mr. J. W. Douglas, who has 

 rendered me much assistance in the study of this genus, and whose 

 knowledge of our British Ileiniptera is so well known.

Occurrence in Britain of Ahdera triguttata, Qyll. — I have much jileasuro in 

 being able to record the capture in this country of Abdera triguttata, Gyll., a species 

 occurring somewhat rarely in Sweden, France, and Germany. It is hardly to be 

 compared with either of our other British Ahderee, but is a little like hifasciata, 

 though larger and much broader (especially behind) in proportion, with the markings 

 of the elytra very different. It varies somewhat (from l^- to IJ lines) in length and 

 very much in colouration, some individuals being mostly lurid-testaceous, with the 

 disc of the thorax, a small scutellar patch and a larger triangular marking on each 

 elytron below the middle dark, whilst others (and those would seem to be the typo 

 form) are pitchy-black, with two ligiit ovate spots below the scutellura, pointed to- 

 wards the suture, down which the light colour runs narrowly until it forms a common 

 larger pale spot before the apex. Every intei*mcdiate grade appears to exist : and, 

 from tlie absence of mention by Gyllenhall or Thomson of any varieties in such a 

 variable insect, it would seem that no largo numbers of it can have come imder the 

 observation of either of those authors. The whole insect is very pubescent, rather 

 coarsely punctured all over ; and has the two basal joints of the antenna) testaceous. 

 Found, somewhat commonly, in company with Zilura firruginea, by my friend 

 Mr. AUin and myself, under (and in cliinks of) bark uf young dead standing Scotch 

 firs, at Aviemore, Inverness-shire, in the beginning of June last. It is one of the 

 most fragile insects I ever met with.— G. C. Champion, 274, Walworth Eoad,
