ATTEMPTED DIVISION OF BRITISH INSECTS. 411 



exteriorly; mandibles long, acute at the apex, and having one 

 tooth internally ; maxillae, with the blade and galea, obtuse, the 

 feeler long and six-jointed ; labium short, ligula more produced, 

 trilobed ; ocelli three ; head large, orbicular ; wings ample, with 

 numerous nervures ; legs short ; podeon fully developed ; body 

 short and robust. Inhabits woods, flying in the sun, settling on 

 leaves, and occasionally, but rarely, on flowers. Tarpa, Lyda, 

 Lophyrus ? which principally differs in its pectinated antennae. 



Natural Order. — Cephites. 



Larva elongate, with its feet obsolete or rudimental. Inhabits and 

 feeds on the stalks of corn and the buds of fruit-trees. Pupa 

 changes within the stalk. Imago, with antennae twenty-jointed, 

 long, filiform, slightly incrassated externally ; mandibles short, 

 broad, trifid ; maxillse with the blade distinct and acute, the 

 galea elongate, and separated from the maxilla by a distinct 

 line, resembling an anchylosed articulation, the feeler long and 

 six-jointed ; labium, with its four parts, perfectly developed, 

 the feeler-bearer elongate, and notched at the apex, the ligula 

 produced and trilobed, and the feeler four-jointed ; ocelli 

 three ; head rather square, broader than the following segments ; 

 prothorax fully developed, cylindrical, quite detached from the 

 mesothorax ; podeon fully developed, divided on the back longi- 

 tudinally ; body elongate ; legs elongate; flight easy and graceful 

 in the sunshine. Settles in abundance on composite flowers by 

 the road-side, and in meadows on Ranunculi. Cephus. 



Class IV. — Coleoptera. 



Larva, with corneous mandibles moving horizontally ; a pair 

 of articulate feet, generally on the second, third, and fourth 

 segment; no other feet, unless a prehensile caudal appendage 

 occasionally present can be so denominated. Food very 

 various. Pupa of nearly uniform appearance. Imago, with 

 the parts of the mouth fully developed; the mandibles moving 

 horizontally, and being employed in mastication. Wings 

 fully developed ; fore-wings hard, crustaceous, not used in 

 flying, when closed meeting with parallel edges, and com- 

 pletely covering the hind-wings, to protect which appears 

 their only office ; hind-wings generally much longer than the 

 body, folded longitudinally and transversely beneath the fore- 

 wings. Prothorax very large ; mesothorax small ; metathorax 

 huge. Food various.
