One male and two females. A minute, delicate, pallid, oblong, 

 convex insect, with i'usco-trifasciate elytra ; the antennae similar in the 

 two sexes, very slender, with joints 1, 2, and 11 stouter; the posterior 

 femora clavate and finely dentate in ^J ; the eyes transverse, entire, 

 convex, and rather small. The strongly deflexed head, sub-cjdindrical 

 body, etc., are suggestive of Hylobaenus, Phytobaenus,a:ud. Notoxeuyleties, 

 and it is probable that X. egregius may have to be separated from 

 XylopMlus Latr., in which it can remain for the present. X. hiimpressus 

 Pic, from Pontianak, Borneo, may be an allied larger form, with 

 larger and more approximate eyes, sub-filiform antennae, unifasciate 

 elytra, &c.

ON SOME ADDITIONS TO THE BEITISH LIST OF COLEOPTEBA. 

 BY E. A. NEWBERY AND W. E. SHARP, F.E.S. 



In an Exchange List of the British species of Coleoptera compiled 

 by us, which has just appeared, the names of certain species and 

 varieties are inserted which have not as yet been brought forward as 

 indigenous. It seems desirable that a short notice of these should be 

 published. 



Bhantus exoletus Forst., var. nigriventris nos. This variety differs 

 from the type form by having the ventral abdominal segments black 

 or pitch-black. This form is not referred to by either Seidlitz or 

 G-anglbavier. It was taken in small numbers at Askham Bog, Torks., 

 by one of us in March, 1895. 



Tachyporus macroptertis Steph. {^^ dimidiatus Steph., ptisillus 

 var. b, Gryll.). This insect stands in most British collections as a dark 

 forai oi pusillus Grrav., from which it may be separated thus : — 



Elytra distinctly longer than thorax, red or red-brown, with side-margins 

 and a space round scutellum more or less infuscate...T. pu$illus Grav. 



Elytra scarcely longer than thorax, black, with apex narrowly pale 



...T. macropterus Steph.
