1. JoPPIDIUM RUBRICEPS, Cress. 
Trans. Amer. Ent. Soc. 1872, p. 160, male and female; J. ru/i- 
ceps, Walsh, Trans. Acad. St. Louis, 1873, p. 70, female. 
This is the typical species of the genus, and a single pair 
was captured in North America on umbelliferous flowers during 
July. I am not aware that it has been noticed since 1873, and 
greatly doubt the synonymy, suggested by Walsh, with Banchus 
e@quatus, Say (Boston, Journ. Nat. Hist. 1836, p. 247; Leconte, 
Writ. Say, ii. p. 701). The typical male was acquired by the 
British Museum in 1878, and the female was possibly destroyed 
in the Chicago conflagration of 1871, at which time Cresson tells 
us Walsh’s MS. was already completed ; this male is from 
‘« Texas (Belfrage),”’ and was labelled by Fred. Smith ‘‘ Joppidium 
nebriceps (sic), Cress.”’ It is at once known from the remainder 
of the genus by its entirely black thorax and abdomen, and its 
bright orange-coloured antenne with their apices alone slightly 
infuscate ; the description of Walsh’s name appears to differ 
solely in its slightly darker flagellum. 
2. JOPPIDIUM DUBIOSUM, Cress. 
Proc. Acad. Philad. 1878, p. 188, male and female. 
Sumichrast found both sexes at Cordova in Mexico; but it 
was unknown to Cameron when writing the Ichneumonide part 
of Biologia Centr.-Amer. of 1885. As its author remarks: ‘‘ The 
female is closely allied to that of rubriceps, Walsh, but distinct
