208 Mr. G. R. Waterhouse's Notes 



We possess two species, viz. : — 



E. cornutum, Mellie, 1. c. p. 362, pi. 4, f. 12. 

 Cis cornutus, Gyll. Ins. Suec. iv. 626. . 



A smallish oblong species (being scarcely 1 line in length), and 

 of a testaceous or fusco- testaceous colour, the legs and antennae 

 paler ; antennae with the two basal joints stout, these followed by 

 two slender joints, of which the first is the longest, then two 

 small transverse joints, and the three-jointed club ; the clypeus, 

 in the male, is produced into two pointed tubercles, which are 

 horizontally compressed ; in the female transverse, rounded, with 

 the margin recurved, and obscurely emarginate in the middle : 

 thorax with the broadest part very near the posterior angles, 

 gently rounded at the sides, and gradually contracted towards the 

 fore part; in the male with two approximated tubercles in front; 

 in the female with an aggregate of small sefse at the same part, 

 leaving, however, a smooth mesial line ; narrowly margined be- 

 hind and at the sides, the convex upper surface distinctly, but by 

 no means thickly punctured: elytra about 2| times the length of 

 the thorax, and very little broader; tolerably well furnished with 

 small yellow setae, more strongly punctured than the thorax, the 

 puncturing not very dense, and having a tendency here and there 

 to form lines. 



This insect I have taken recently at Hawkhurst. 



Ennearthron affine, Mellie, 1. c. p. 364, 2, pi. 4, f. 13. 



Cis affinis, Gyll. Ins. Suec. iv. 629. 



— frontlcornis, of Stephens' Collection. 



Is considerably smaller (being about f of a line in length), and 

 relatively narrower than the preceding, from which it is further 

 distinguished by its pitchy-black colour, less strongly and thickly 

 punctured upper parts, its dull thorax, and less dense setae on 

 the elytra ; these are, however, conspicuous, being white and 

 rather strong, and arranged in rows. The clypeus, in the male, 

 is furnished with two acute tubercles. 



Genus Octotemnus, Mellie, 1. c. p. 384,* is founded on the — 

 Cis gJahriculus, Gyll. Ins. Suec. iv. 629. 

 Oct. id., Mellie, 1. c. p. 385. 

 Cis nitidus, of Stephens' Collection. 



A small, glossy, pitchy-black insect, bearing a superficial resem- 



• The two genera Ennearthron and Octotemnus were first pointed out by M. 

 Mellie, in the " Revue de la Society Cuvierienne" for Rlarch, 1847.
