ORDER COLEOPTERA. 349 



P. far. Lin. Fab. P. latro, striatus, F. Oliv. Col. II. I7, 

 i. I, 3. ii. 9, Var. of the male ; a line and a half in length, 

 of a clear brown ; antennae of the length of the body ; corslet 

 having on each side a pointed eminence, and two others 

 rounded and covered with a yellowish down in the interval ; 

 two transverse bands, greyish, and formed by hairs on the 

 cases. 



According to Degeer, it lives on flies, and other dead in- 

 sects with which it meets. Its larva makes a terrible devas- 

 tation in herbals, and collections of natural history. 



P. imperialis, Fab. Oliv. ibid. I. 4, remarkable for two 

 spots of the cases, representing, by their union, the rude figure 

 of an eagle with two heads. Lives on old wood. 



This species, it appears to us, ought to be placed in the 

 genus Hedobia, of the catalogue of the collection of M. le 

 Comte Dejean. It differs from that of Ptinus, by having 

 more separated antennae, a little serrated, and particularly 

 by the tarsi, which are short, and composed of articula- 

 tions almost in the form of a heart, more broad, especially 

 the last. The crotchets of this last are even concealed. In 

 the Ptini these tarsi are narrow, with the last articulation in 

 the form of an inverted cone. The antennae are approximated 

 at their base. 



I have frequently found on excrements the P. Germcmus, 

 (Lat. Crust, et Insect. I. p. 279), which has several relations 

 with P. latro. {See, for the synonimy of the species of this 

 genus, Schoenhen, Syn. Insect. II. p. 106.) 



GiBBiDM, Scop. Ptinus, Fab. Oliv., 



In which the antennae are inserted in front of the eyes, which 

 are flatted and very small, in which the scutellum is wanting, 

 or is not very distinct, and whose body is short, with the 

 abdomen very large, swelled, almost globular, and semi- 

 transparent. The antennae are more slender towards their
