1. JOPPIDIUM RUBRICEPS, Cl'eSS. 



Trans. Amer. Ent. See. 1872, p. 160, male and female ; J. rufi- 

 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 

 cBquatus, Say (Boston, Journ. Nat. Hist. 1836, p. 247 ; Leconte, 

 Writ. Say, ii. p. 701). The typical male was acquired by the 

 British Museum in 1873, 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 antennae 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. 138, male and female. 



Sumichrast found both sexes at Cordova in Mexico ; but it 



was unknown to Cameron when writing the Ichneumonidae part 



of Biologia Centr.-Amer. of 1885. As its author remarks : " The 



female is closely allied to that of rubriceps, Walsh, but distinct
