S70 MODERN CLASSIFICATION OF INSECTS. 



I am indebted to Mr. Ingpen for a larva (^Jig. 44.. 21.) taken in 

 rotten wood in Bewdley Forest, which varies from the Ceramby- 

 cideous larvae, in the larger size of the bead, and in the abdominal 

 segments being furnished with lateral fleshy lobes, in the terminal 

 segment of the body being produced in an obtuse point over the 

 anus ; the body is of equal breadth throughout, and subdepressed ; 

 the jaws and upper lip are advanced. It has six very short legs, and 

 the remaining segments unprovided with flesh}' retractile prolegs. It 

 was found in company with Mesosa nebulosa ; but I have no hesi- 

 tation in giving it as the larva of Ilhagium inquisitor. 



It appears to be a peculiarity in the geographical distribution of 

 these insects, that none exist in India (Westermann, in Silherm. 

 Rev. Entomol. No. 3.). 



These insects are of moderate size, and are generally gaily coloured. 

 There are about thirty British species belonging to the genera ar- 

 ranged in my Synopsis, according to the revision of M. Serville. 



Amongst the exotic genera, Vesperus DeJ., composed of two species 

 inhabiting the south of Europe, merits notice from the remarkable 

 diversity exhibited by the sexes ; the male being narrow and winged, 

 and the female very broad, with the elytra small, soft, and attenu- 

 ated, and the wings rudimental. 



In the third subsection of the Pseudotetramera, Phytophaga* (Eu- 

 PODA Latreille), the body is generally thick, and of an oval, subor- 

 bicular, or quadrate shape. The head is short, without any frontal por- 

 rection, and immersed as far as the eyes in the thorax ; the antennae 

 generally much shorter than the body, and filiform, or but slightly 

 and gradually thickened to the tips, with moniliform or conical joints 

 (^fig. 45. 10., 46. 7.) ; the parts of the mouth are short, or but little 

 exposed ; the jaws are short, corneous, trigonate, with the outer edge 

 curved and thickened ; the lower jaws are terminated by two lobes, 

 the external one often resembling a palpus, and the internal one 

 not being furnished with a corneous tooth at the tip ; the lower lip is 

 thick and generally quadrate ; the palpi are terminated by a short 

 ovoid, or subulated joint ; the tibiae are either unarmed, or furnished 

 with very short spurs; in some species the hind legs are formed for 

 leaping. 



* Kirby {Fauna Bor. Ainer. p. xxvii. ) ; but in p. 227. the term is changed to 

 Phyllophaga : I have preferred the former as being more correct.
