INSECTS. 287 



larvze, of a dirty white colour, and of an elongated form, have six short feet, a large 

 and scaly head, two antennae of five joints, nine stigmata on each side, and a body 

 of thirteen segments. They live three or four years in this state, assume afterwards 

 the pupa foim, and appear as perfect insects in the third or fourth year. Many 

 expedients have been used by planters and agriculturists to destroy or diminish the 

 number of these larvae in places where their multiplication is injurious to vegetables. 



M. vulgartSj Lat. The Cockchaffer. Black, with the antennae, the 

 anterior margin of the hood, the elytra, the feet, excepting part 

 of the posterior thighs, reddish bay ; thorax with the lateral bor- 

 ders slightly dilated and rounded in the middle, and a black or 

 red cicatrix near the margin of each ; elytra with each four lon- 

 gitudinal ribs ; breast gray and downy, and the margins of the 

 abdomen with a row of white triangular spots. Common over all 

 Europe. Sharv, vi. pi. 3. 



M.yW/o, Lat. Body brown or black, with numerous white spots 

 formed by the down ; hood straight before, with a white line on 

 each side ; thorax with three white lines ; scutellum with a white 

 cordiform spot ; abdomen cinereous. 16 lines long. Inhabits 

 Europe. Shaw, vi. pi. 5. 



5. ANTHOBII. 



Gen. GLAPHYRUS, Lat. Melolontha, Fab. 

 Antennae of ten joints, of which the last three form a leafy al- 

 most ovoid club ; palpi terminated by a thicker nearly ovoid 

 joint ; labium with two lobes projecting beyond the chin ; 

 jaws bifid, with their exterior division almost ovoid, and the 

 internal one very small, in the form of a tooth ; mandibles 

 corneous, projecting, angular, and dentated ; labrum project- 

 ing. 



G. Manrus, Lat. Body blue green, with the abdomen, antennae, 

 except at the base, the legs and tarsi of the anterior feet brown- 

 ish. Inhabits Barbary. Lat. Gen. ii. 117. 



6. MELITOPHILI. 



Gen. TRICHIUS, Lat. Scarabceus, Lin. 

 Thorax rounded, almost orbicular ; a scaly plate between the 

 posterior and exterior angles of the base of the elytra, form- 

 ing a prolongation of the pectoral plate ; jaws narrow ; man- 

 dibles almost membranaceous ; labrum membranous, concealed 

 under the hood ; last joint of the palpi ovate ; antennae of 

 ten joints, the last three forming a club. 



The insects of this genus differ but slightly from those of the genus Cetonia in 

 their organs of mastication ; but their jaws are proportionally narrower, and the 

 last joint of the palpi is less elongated. The chief distinction, however, is found 

 in the form of the thorax, which is subtrigonal in the Cetonice, and orbicular in the 

 present genus. They are chiefly found on flowers. 



T. eremita, Lat. Shining black, slightly coppery, with two ribs and 

 two elevated tubercles on the thorax ; a furrow on the scutellum, 

 and the elytra slightly rugous. About an inch long. Inhabits 

 Europe, on the dead trunks of trees. Lat. Gen. ii. 123.
