bidentate and tridentate species should the mandibles be worn 
down at the tips. 
In Cuphopterus, male, the two upright spines which appear at 
the base of the seventh ventral segment are processes of the 
pleural region of the seventh dorsal; the spines which truly 
belong to the seventh ventral are very small and only visible 
when the segment is fully extended. 
In Hoplocrabro, female, there is often a very minute tooth on 
the lower edge near the apex of the mandibles, and the actual 
apex in some aspects may appear truncate rather than rounded,,. 
but as the genus is well defined by other characters, the mandi- 
bular structure is of less importance. 
It should be understood that in my paper on the Crabronide: 
it was my object, so far as possible, to supplement the excellent 
descriptions of Edward Saunders, and consequently no allusion 
is made to many good specific characters (e.g. those of the front 
legs of Thyreopus) which have been detailed by him.

BRITISH ORTHOPTERA IN 1914. 
By W. J. Lucas, B.A., F.E.S. 
LirtLe information of interest has come to hand concerning 
the British Orthoptera in 1914; but the following new locality- 
records and short field-notes.should no doubt be published for 
the benefit of students of the Order. 
Forficulodea.—On March 15th earwigs and eggs were found 
more than once in stumps from which Scotch firs had been cut 
down on Esher Common, Surrey. A batch of the latter was 
brought home, together with a female imago found at the same 
time, one of whose cerci was broken. In captivity she did not 
seem to take any notice of the eggs, which possibly were then 
dead. On April 20th Dr. T. A. Chapman gave me a living nymph 
of Forficula .auricularia, Linn., with the following history :— 
‘Karly in January I brought into the house a plant in a pot 
that had up till then been out-of-doors. One day early in 
February I found on a leaf of the plant a young earwig. I 
expected others to shew themselves, but none did. It was so 
small that I was rather surprised it was out of the ‘nest.’ I 
have since kept it and fed it. It has moulted three times when 
it ate the cast skins, and has regenerated two joints that were 
missing from an antenna. The problem was, how did it happen 
that there was a solitary earwig that ought not to have left its 
mother at such a date? It must have been still younger when 
brought in, as it was several weeks later when I found it.” 
I saw no evidence of its moulting again till May 10th, when
