can 
156 Mr. J. B. Bridgman on some additions to 
this they vary to the thorax almost entirely red; the 
same with the cox; the Ist segment of the abdomen 
also ranges from red to piceous, with the base darker. 
Pezomachus incertus, Foerst. 
Foerst., Mon. Gat. Pez. 128, 61. 
This species also does not appear to be uncommon. 
Mr. Billups captured five or six specimens at Headley 
Lane last year, and it is not scarce round Norwich. Like 
the last species, this varies much in the intensity of the 
colour of the legs and thorax. 
Pezomachus Miilleri, Foerst. 
Foerst., Mon. Gat. Pez. 127, 60. 
This is another species taken by Mr. Billups at Wey- 
bridge, Leatherhead, and Rainham; all during 1880. 
Pezomachus juvenilis, Foerst. 
Foerst., Mon. Gat. Pez. 186, 72. 
I took two specimens of this species at the end of 
September last year in this neighbourhood ; it has also 
been taken by Mr. Billups in the Mickleham Valley, 
October, 1880. 
Pezomachus dubitator, Foerst. 
Foerst., Mon. Gat. Pez. 159, 105. 
I have taken several specimens of a Pezomachus which 
I think must be this species, but they differ slightly 
from Foerster’s description; he says, ‘‘the abdomen 
to the apex densely punctured and haired,” which, I 
suppose, means the whole abdomen is evenly sculptured. 
This is not the case with my insects; the first three 
segments are densely haired ; the hairs on the remainder 
are more scattered. Similar specimens have also been 
taken by Mr. J. W. May and Mr. E. A. Butler. It is 
much like P. transfuga. 
Pezomachus micrurus, Foerst. 
Foerst., Mon. Gat. Pez. 155, 98. 
I have seen a Pezomachus which I believe to be 
this species; it was taken by Mr. E. Parfitt in the
