on the anterior femora of the male; of this, however, there is sometimes 
no trace: the posterior femora are furnished behind with a row of ir- 
regular teéth, and these, in some males, have entirely disappeared; the 
size varies greatly (length 5 to 9 lines), and the colour is black, or 
black with green or blue reflections. 
G. corruscans, Chev., is distinguished from pyreneus by its brilliant 
purple golden colour, and by the abdominal punctuation being greater ; 
the colour, however, is toned down in some individuals to a dull brassy 
tint ; and the abdominal punctuation is scarcely greater than in ordi- 
pyreneus ; the thorax is sometimes a little shorter than in some indivi- 
duals of pyreneus, but in others it is quite as long ; this form is confined 
to the mountains of Spain, and it appears to me to possess no characters 
by which it can be distinguished as a species from G. pyreneus. I have 
a series before me from the Guadarrama, and another from Galicia; 
these do not quite agree, the Guadarrama individuals being of a more 
purple and beautiful colour than those from Galicia. 
In the “Insecten Deutschlands,’ Erichson mentions, under the 
name of G. splendens, Zieg., a variety from Italy, which should be re- 
ferred I think to G. pyreneus ; but Iam not sure of this, as Erichson 
regarded corruscans as distinct from vernalis, but placed splendens as a 
var. of vernalis ; the characters, however, that he gives for splendens are 
much the same as those he gives for corruscans. The synonymy is 
G. pyrenzus, Charp. 
vernalis, Steph. 
politus, Muls. 
v. corruscans, Chev. 
? v. splendens, Zieg. 
This species appears to be less widely distributed than vernalis, 
and also more local. It occurs in England (but not in Scotland or 
Sweden), in France, the Pyrenees, and the Asturias, and (as corruscans, 
Chey.) in other parts of Spain. 
I have received from M. Deyrolle, under the name of G. molestus, 
Fald., a Sternotrupes closely allied to the two species now under con- 
sideration, but I think really distinct. The G. molestus of Falderman 
is, however, according to Jekel, an Anoplotrupes; and in this case the 
insect from M. Deyrolle requires description. 
G. (Sternotrupes) CAUCASICUS, nov. spec. 
Oblongo-ovalis, supra niger, nitidus, prothoracis elytrorumque margi- 
nibus metallescentibus, subtus viridi-ceruleo-micans ; supra levis (capite 
prothoracisque margine externo exceptis); subtus abdomine confertim 
equaliter punctato. Long. 74 lin., lat. 4 lin.
