SUPPLEMENT, &C. 565 



The genus Pimelia of Fabricius, formed of many apte- 

 rous tenehriones of Linnaeus, has suffered in succession divers 

 modifications. Thunberg has made of the Pimelia ciliata, a 

 peculiar genus, which he names Eurychonis. Herbst has 

 adopted it, and has instituted two others, AMs and Stenosis, 

 which he has similarly detached from the pimelia of Fabricius. 

 M. Latreille, in his " Precis des Characteres generiques^' has 

 united these first two sections into one, to which he has pre- 

 served the denomination of Eurychorus. Fabricius, in his 

 Eleutherata^ admits the genus Eurychorus of Thunberg, 

 and that of Akis, but he refers to the latter the Stenosis of 

 Herbst, and the Pimelia of the same author, whose corslet 

 is orbicular. M. Latreille, afterwards, established along with 

 them, the genus Tentyria. Some other pimeliae of these 

 two naturalists, tolerably analogous in the general form of 

 the body to Tentyria, but which differ in the antennae, have 

 been united into another generic section called moluris. 



The habits of these insects is the same as those of the tribe 

 in general. Pimelia htpiinctata, which has been observed in 

 a living state by M. Latreille, inhabits the sandy borders of 

 the Mediterranean. It conceals itself in holes, which it ex- 

 cavates very promptly by means of its feet. We possess, 

 otherwise, no fact relative to the habits and metamorphoses 

 of this species or its congeners. 



The genus Pimelia, though much more restrained than in 

 its origin, is still composed of a great number of species, but 

 the determination of which is very difficult. The authors 

 who have described these insects, have neglected many cha- 

 racters in detail ; such as the precise form of the articulations 

 of the antennae, those of the feet, their relative proportions, 

 and the employment of which, seeing the multitude of 

 species collected in the East, by Olivier, and M. M. Labil- 

 lardiere and Savigny, is absolutely necessary. Accordingly 

 we find that many naturalists have referred to various species
