CERAMBYCIDiE. TETROPS. 241 



tured, the latter with a faint wAzYw/i-pubescent central line: scutellum also 

 whitish : elytra clothed with a delicate ashy down ; each with an abbreviated 

 elevated central line, and a second within the margin : anterior legs luteous, 

 with the base of the femora black. Head in one sex pubescent, in the other 

 glabrous and punctate in front. 



Not uncommon in some places within the metropolitan district : 

 I have frequently captured it in Maiden-lane, Copenhagen-fields, 

 in June, in a hazel bush, on the inner pith of the twigs of which its 

 larva subsists. " Cambridge, Monk's-wood, Hants." — C. C. Babing- 

 ton, Esq. " Cowpen, near Cambridge."- — -Rev. L. Jenyns. 



Sp. .9. oculata. Lineari-elongata, angusta, luteo-testacea, capite, antennis, elytris 

 pimctisque duabus thoracis nigris. (Long. corp. 8 — 10 lin.) 



Ce. oculatus. Linne. — Don. v. pi. 305. — Sa. oculata. Steph. Catal. 198. No. 

 2031. 



Linear-elongate, narrow : head and antennas black : labrum and palpi, abdomen, 

 legs, scutellum and thorax pale rz^fbz^^-yellow, or testaceous, the latter luith 

 two remote black dots: elytra Sishy-black, deeply and somewhat regularly 

 punctured. 



Also a local and rare species ; found most abundantly in the Isle 

 of Ely : I have two specimens which were captured by Dr. Leach, 

 in Scotland. " Baron-wood." — 2^. C. Hey sham, Esq. " Once 

 taken at Swaffham Bulbeck on wing." — Rev. L. Jenyns. 



Genus CCCLXXVL— Tetrops, Kirby. 



Palpi with the terminal joint conic-acute. Antennce rather stout, shorter than 

 the body, pilose, basal joint slightly robust, second a little elongate, third and 

 fourth of equal length, remainder gradually decreasing in length; the eighth, 

 ninth, and tenth being nearly equal, and the eleventh about as long as the 

 seventh, and slightly acuminated : head short, deeply immersed in the thorax, 

 which is small, deeply constricted within the base and apex, cylindric, un- 

 armed : eyes four, superior bent : elytra linear, soft, with the apex subtrun- 

 cate : legs short : femoi^a simple : tarsi also simple. 



One can scarcely conceive that at the present day this genus 

 should continue to be united to Saperda without the slightest 

 allusion to its discrepancies from the type of that genus; such, 

 however, is the case in the most recent illustration of the latter 

 genus ; from which the present not only differs by its comparatively 

 minute bulk — being the smallest European species of the family, — 

 but by having the eyes each decidedly broken into two separate
