INSECTA COLEOPTERA.

once at Fontainbleau, and A. punctum, from Italy, resemble the A. 
nigricornis ; A. parvulus, found at Fontainbleau, in a decayed oak, is 
very similar to my A. gramihim, and dilfers only in the elytra being 
much closer punctured. 
In D’Orbigny’s Voy. d. I’Am. Mer, this family has been increased by 
Blanchard with a number of new species : Hololepta attenuata, from 
Bolivia ; Saprinus ornaUis (this name has already been given by the 
reporter to the 8. interruptus, Fisch,), allied to the 8. decoratus of the 
reporter, and 8. patagonicus, both abundant in Patagonia ; 8. nigrita, 
from Maldonado and Monte Video ; 8. erythropus, from Buenos Ayres ; 
8. piceus (this name also is not free, as Hist, piceus, Payk., is a 8apri- 
nus), from Corrientes ; 8. impressifrons, from Bolivia; 8. atro-nitidus, 
from Corrientes. 8aprmus incisus, of the reporter, from Van Diemen’s 
Land, is also to be mentioned (Arch. 1842, i. p. 152). 
Dermestini. — A new species, Megatoma adspersa, has been found by 
D’Orbigny abundantly in Bolivia, in houses and walls; and has been 
described by Blanchard, in the Voy. d. I’Am. Mer. 
Megatoma morio and Trogoderma riguum of the reporter, are two 
new species from Van Diemen’s Land (Arch. 1842, i. p. 152). 
Byrrhii. — This family has been treated of by Steffahny in an excel- 
lent dissertation, “ Tentamen Monographias Byrrhorum” (also printed 
in Germar’s Zeitschr. f. d. Entomol., iv. p. 1). The difficult and 
hitherto much mixed species are firmly established. The genus Byrrhns 
is, following Stephens’ arrangement, confined to such as have the antennae 
gradually thickened ; and also show some variations in the form of the 
terminal joint of the maxillary palpi, the shape of the lobes of the 
labium, the toothing of the mandibles, and in the presence or absence 
of a membranous appendage on the under side of the third tarsal joint, 
which are used for the certain distinction of the species. B. scahri- 
pennis, approximating to the B. gigas, from the Styrian Alps ; B. regalis, 
Dahl., from the Banat; B. insignis, near to the B. murinus, from 
Turkey ; B. decorus, allied to the B. lariensis, Heer, from the Banat ; 
and B. scutellaris, Esch., from Kamtschatka, are new. The B. striatus 
of this author is the same with B. glabratus, Heer. The genus 8ynca- 
lypta, Dillw., with a three-jointed club of antennae, contains B. setiger, 
lU.; B. arenarius and pusillus, St. ; and a third new species, 8. striato- 
punctata, Dej., from Spain. Pedilophorus, a new genus, with a five- 
jointed club of antennae, broad tibiae, and the third tarsal joint with an 
appendage, is founded on B. auratus, Duft. {nitens, Germ.) 8implo- 
caria, Marsh., with a five-jointed club of antennae, narrow tibiae, simple 
tarsi, embraces B. semistriatus, F., and picipes, 01. I have also found 
that Amphicyrta, Esch., which Dejean places between the Chrysomelce 
and Colaspes, belongs to this family. It has filiform antennae, the third 
tarsal joint has a membranous appendage, and narrow tibiae with im-
