front, and its centre is formed beneath into a longitudinal tube, within 

 which the head is capable of being entirely withdrawn ; the anterior 

 angles of the latter (7%. 27. 2., the head extracted from its tube) are 

 formed into two rounded pilose lobes, which Dr. Perty has supposed 

 serve as organs of taste ; but as they are in no wise connected with 

 the mouth, this opinion cannot be maintained. The same author has 

 represented the head extracted from its prothoracic sheath, having a 

 pair of large lateral ocelli, and a pair of thick jointless organs, which, 

 in two specimens which I have dissected, were entirely immersed in 

 a cavity at the anterior angles of the head. These organs, which 

 Perty calls tentacula, are rudimental antennae, and call to mind the 

 sunk antennae of the Hippoboscae. The mouth, which Perty has entirely 

 overlooked, is, indeed, very minute, but consists^ as usual, of a pair of 

 mandibles, very acute and small ; a pair of maxillae, of which the 

 terminal lobe and 4-jointed palpi are capable of being withdrawn into 

 the extremity ; a broad mentum and lip ; and a pair of minute 3-jointed 

 labial palpi ; the mentum and maxillae are soldered together, forming a 

 large flat membranous plate, covering the under side of the head in 

 the centre. The mesothoracic, metathoracic, and eight following seg- 

 ments, have each a pair of spiracles. 



I have also figured, from the collection of the Rev. F. W. Hope, 

 another remarkable larva (^fig. 28. 1.), nearly allied to the preceding, 

 but of a narrow form, and of a black colour, with four longitudinal 

 series of bright orange-coloured tubercles. The under side of the 

 prothorax is formed as in the preceding, and the parts of the mouth 

 are very weak. As the latter, and especially the mandibles, are very 

 long and acute in the larvae of the Lanipyres, the supposition that 

 these larvae belong rather to some species of Lycus is strengthened. 



Tlie fourth family, TELEPHORiDiE *, is so named from the typical 

 genus Telephorus of De Geer and Schaeffer, corresponding with the
