Pemphredon as having spoon-shaped and quadridentate 
mandibles, and adduces the P. lugubris of his ‘ Histoire’ 
as the type, and refers the P. minutus (which he there for 
the first time states to have been the original type of his 
genus Pemphredon in the ‘ Précis’), to the genus Stigmus 
of Jurine, and makes it the first section of this genus. 
In the ‘ Nouveau Diction. d Hist. Naturelle; tom. xv. 
p- 151, 1817, he further confirms this, by stating that the 
mandibles of Pemphredon ‘ are stronger (in comparison 
with Stigmus), and dentate all along their inner edge: 
thus, therefore, although the original type of this genus was 
the Pemphredon (Diodontus) minutus, F.; yet as Latreille 
subsequently changed his views, I necessarily follow the 
course he adopted, and consider the Crabro luqubris, F., 
as the true type of the genus Pemphredon. I have given 
this history of the genus in consequence of Mr. Westwood 
having, by a string of inaccuracies in a recent periodical,* 
mtroduced confusion where the course was exceedingly 
clear, and this is the more unfortunate, as they are pro- 
duced as an example in a paper on nomenclature, where 
the strictest correctness was requisite, and even addition- 
ally requisite, if such a condition be possible where ac- 
curacy is always indispensable, because he there corrects 
what he considers the imaccuracy of Mr. Curtis, but who 
is certainly right. I hope this will be read and understood 
in its proper sense, and not be misconstrued into invi- 
dious carping, as it is my wish to do uniform justice, 
without which, truth, which should be the great and para- 
mount object of us all, is unmercifully sacrificed. It is 
remarkable that St. Fargeau should not have subdivided
