EEATERIDiE. CTENICERUS. 265 



This genus, termed Cleniocerus by Dr. Leach, in allusion to the 

 conspicuous antennae of some of the males, may be readily known 

 from all the preceding ones in the family, by having the second 

 joint of the antenna? alone minute and nodose, the third being 

 nearly as long and of similar form with the fourth ; the terminal 

 one elongate ; the thorax considerably longer than broad, a little 

 depressed, the body usually adorned with rich metallic hues, and 

 the antenna? more deeply serrated ; by several of which characters 

 it may also be distinguished from the following genera. 



A. With the antennae pectinated in the males; serrated in the females. 



"rSp. 1. aulicus. Obscure viridi-oeneus, elytris testaceis immaculatis. (Long. 



corp. 7—8 lin.) 

 EL aulicus. Panzer.— CI. aulicus. Steph. Catal. 124. No. 1264. 



Head and thorax obscure brassy-green, the former depressed and punctulated, 

 the latter slightly pubescent: scutellum concolorous with the elytra, which 

 are pale immaculate-testaceous, striate-punctate, with a slight impression on 

 each side at the base : legs and body beneath dull blackish-brass : antennae 

 black. 



In the British Museum is a pair of this insect, said to have been 

 taken by Dr. Leach in Devonshire, about four years since ; but 

 doubts have recently been started by Mr. Curtis, with his wonted 

 caprice, as to its indigenous origin ; and also of several other species 

 reported to have been captured about the same period, some being 

 admitted and others doubted. 



Sp. 2. pectinicornis. Elongatus viridi-ceneus nitidus, thorace sidcato, elytris 



punctato-striatis. (Long. corp. 7 — 8 lin.) 

 El. pectinicornis. Linnc.—Don. x. pi. 356. /I 2. — CI. pectinicornis. Steph. 



Catal. 124. No. 1265. 



Above of a rich shining brassy-green : head rather obscure, punctate : thorax 

 with a dorsal channel, the posterior angles stout, elongate, carinated above : 

 scutellum fuscous : elytra rich green, tinted with aeneous, rather deeply punc- 

 tate-striate, the interstices finely punctured and slightly pubescent: body 

 beneath more obscure, pubescent : legs and antennae black, the latter in the 

 male elongate, deeply pectinated ; in the female short, serrated. 



Found chiefly I believe in hilly and mountainous districts; 

 abundant on the Malvern Hills, and in many parts of the north of 

 England. " North Wales."— Rev. F. W. Hope. « Near York 

 and Newcastle ; also near Wastwater, Cumberland : females rare."
