are produced into advanced points. A very splendid species from 

 Mexico, witli long curved mandibles, very long palpi, and spinose 

 head and thorax, forms the genus Psalidognathus Gray i^Griff. Anitn. 

 Kingd. pi. 6. and 14.). M. Bohemann has described several species of 

 the same genus in the Trans, of the Royal Acad, of Stockholm for 1834. 

 The Brazilian genus Psygmatocerus Perty (Isis, vol. xxi. No. 7.), is 

 remarkable for the antennae being furnished with very long, flattened, 

 lateral plates in the males. 



The second family, Cerambycidje* Leach, comprising the Linna^an 

 genera Necydalis and Cerambyx (except such species of the latter as 

 constitute the preceding family) is distinguished by the exserted and 

 transverse labrum (^r/. 44. ll.) ; the reniform or lunate eyes; the 

 antennae very long, inserted close to the inner margin of the notch 

 of the eyes, and never serrated ; the maxillary lobes are ctistinct and 

 membranaceous (^/ig. 44. 12. maxilla of Cerambyx moschatus ; 44. l. 

 ditto of Saperda carcharias) ; the body is long and subdepressed, occa- 

 sionally subconvex ; the femora often clavate ; and the tarsi short, 

 and of the ordinary pseudotetramerous form. The maxilla, in some of
