CYPHONID.E. CYPHON. 288 



mainder of nearly equal length, filiform ; the fourth and last heing rather the 

 longest; or with the fourth to the tenth joints inclusive slightly pectinated or 

 serrated. Head transverse, in general concealed beneath the anterior margin 

 of the thorax, which latter is transverse, margined laterally, rounded in front 

 and mostly sinuated behind : body ovate or oblong, sometimes rounded : legs 

 short ; femora compressed, slender : tibia with the apex unarmed, or fur- 

 nished with a very minute spine. 



The elongate antennae, slender hinder femora, and unarmed tibiae 

 enable us with facility to discriminate the insects of this genus from 

 Scirtes : — there is nevertheless considerable diversity amongst the 

 species; and doubtless the time is not far distant when the first 

 and the two last species will be separated into other genera : Cy. 

 chrysomeloides, of which the male has slightly pectinated antennae, 

 is evidently more allied to this than to the preceding genus. 



A. With the head concealed beneath the thorax. 



a. The body hemispheric : antenna serrated. 



Sp. 1. chrysomeloides. Ferrugineo-testaceus, pubescens,oculis nigris, elytris punc- 



tulatis. (Long. corp. 2\ lin.) 

 Cy. chrysomeloides. Wilkin MSS.—Steph. Catal. 128. No. 1298. 



Rufo- or ferruginous-testaceous, pubescent, eyes black: scutellum rather large, 

 oblong, triangular: elytra large, very convex, thickly and rather coarsely 

 punctured: body finely punctulated beneath : legs and antenna? pale-testa- 

 ceous, the latter more or less serrated. 



Apparently very rare : I once took a specimen many years since, 

 in Coombe-wood, and subsequently obtained a second example 

 from the same locality, and an original specimen from the Mar- 

 shamian collection : these, with two others, are the only examples 1 

 have seen. 



b. The body oblong-ovate : antenna; simple. 



Sp. 2. melanurus. Oblongo-ovatus, testaceus, pubescens, elytrorum apice abdo- 



mineque J'uscis, antennisj'uscis bast teslaceis. (Long. corp. 2 — 2 J, lin.) 

 Cy. melanurus. Fabricius.—Steph. Catal. 128. A r o. 1299. 

 Oblong-ovate, testaceous, pubescent, shining; with the apex of the elytra and 



the abdomen fuscous ; the antennae fuscous, with the base testaceous : eyes 



black. 

 Variable in colour: sometimes entirely rufo-testaceous, with the eyes and tip of 



the antennae alone black. 



Occasionally met with in plenty ia the neighbourhood of the
