372 MANDIBULATA. COLEOrTERA. 



Green above; head black : thorax with the posterior angles somew'hatacu?ninaied, 

 the disc obsoletely punctured: elytra ample, with the sides posteriorly 

 rounded ; the disc longitudinally convex, and throughout somewhat deeply 

 and coarsely punctured ; the lateral margins deflexed and expanded : breast 

 black ; abdomen yellow : legs short flavescent. 



Very rare : I have hitherto seen but two specimens only, which 

 were captured in Devonshire. 



Subsection III. — Trimeri, Dumeril. 



Body hemispheric or oval. Antennce 11-jointed, short, gradually thickening to 

 the apex, or abruptly clavate: palpi short, filiform; or with the terminal 

 joint securiform-truncate : mandibles horny, broad, trigonate, compressed, 

 acute, the apex sometimes bifid : maxillce membranaceous, bilobed, the inner 

 lobe small: head deeply inserted in the thorax ; the latter short, transverse; 

 or subquadrate, flat : elytra arched, very convex, and covering the abdomen, 

 which is ample ; flat or convex beneath : legs rather short, unarmed ; tarsi 

 frequently three-jointed only, sometimes tetramerous.

 Britain, thus cursorily distinguished.

Family LTII.— COCCINELLIDJE, Latreille. 



Maxillary palpi large, with the terminal joint largest, and generally securi- 

 form ; labial small, subfiliform : labrum narrow, elongate, membranaceous. 

 Antennae shorter than the thorax, and more or less distinctly thickening to 

 the apex, in the typical genus rather abruptly clavate, the club in form of a 

 reversed triangle: Ziorfy hemispheric, or short-ovate: ^/wraar transverse, broad, 

 the hinder margin forming a reversed arch : elytra ample, convex, covering the 

 abdomen, which is flat beneath ; tarsi obscurely tetramerous, or trimerous. 



The insects of this family are known by the familiar names of 

 Lady-bird, Lady-cow, &c. They are of moderate size, and do not 

 possess the brilliancy of metallic colouring which so pre-eminently 

 distinguishes many of the insects of the prececling subsection, though 

 their colours are nevertheless very gay and lively, consisting gene- 

 rally of rich tints of red, black, luteous or whitish, varied with spots
