232 MANDIBULATA.— COLEOPTERA. 



joint stouter than the others, short, ovate : head deflexed : clypeus subemar- 

 ginated : thorax subquadrate ; with the margins denticulate, and two longi- 

 tudinal wrinkles : scutellum elongate, triangular : elytra short, abruptly de- 

 pressed on the sides : abdomen with a series of spiniform scales at the apex, 

 and in the female with an acute ovipositor : anterior tibiw with five teeth 

 on the outer edge ; hinder tarsi with the basal joint elongate ; claws simple. 



The smaller bulk of the only indigenous species, compared with 

 the Trichii, at once points out a dissimilarity therefrom ; but the dif- 

 ference in the form of the terminal joint of the palpi, the deflexed 

 head, subquadrate, longitudinally porcate, and denticulated thorax, 

 and five-toothed anterior tibise, with the spiniform process at the 

 apex of the abdomen, may also be noticed.

Black, varied with black and white scales, somewhat rugose-punctate : thorax 

 slightly narrowed in front, the disc unequal, with two longitudinal wrinkles, 

 and spotted with white ; elytra also with white spots, each with four some- 

 what obsolete, waved, striae : the body beneath and anus clothed with whitish 

 or cinereous scales, with two black spots near the latter; legs black. 



This insect has recently been captured in the west of England ; 

 and two specimens in the late Mr. Francillon , s cabinet are said to 

 have been taken in a chalk-pit in Kent. " I have received this 

 species from Bath alive, also from Devonshire." — G. Wailes, Esq. 



Genus CCXIII. — Cetonia, Fabricius. 



Antenna short ; the basal joint robust, glabrous, the capitulum elongate, tri- 

 phyllous ; the first joint thereof dilated in the centre. Palpi short, with the 

 terminal joint elongate, ovate-cylindric : mandibles short: head moderate: 

 clypeus quadrate, emarginate : thorax subtrigonal, truncate anteriorly : elytra 

 abruptly sinuated towards the base, externally, with a triangular scale inter- 

 posed between the outer base and the posterior angles of the thorax : sternum 

 produced anteriorly ; scutellum large, elongate: body short, ovate, depressed, 

 broad. 



The anteriorly produced sternum, large scutellum, externally 

 sinuated elytra, and above all the singular interposed triangular 

 process between the base of the elytra and that of the thorax, at 

 once show the distinction between Cetonia and the other indigenous
