tige, et plusieurs autre petits Chlorops de la second 
espece qui dévorent l’epi. Ces deux espéces se com- 
portent, pour leurs métamorphoses, de la maniére qui a 
été indiquée plus haut.” 
The Memoir of M. Herpin was accompanied by a 
Supplemental Memoir by M. Guérin-Méneville, illus- 
trated with six coloured plates. In this memoir the first 
species described by M. Herpin, and incorrectly referred 
by Olivier and Dagonet to the Musca pumilionis of 
Bjerkander, was affirmed to belong to the genus Chlorops 
(‘‘ tandis que l’autre est une Oscinis’’), and was described 
under the name of Chlorops lineata.* ‘‘Flavicans; an- 
tennis, vertice macula triangulari, thorace vittis quinque 
nigris; abdomine flavo, fasciis punctisque duobus 
basalibus fuscis, ano flavo, pedibus flavis, tarsis anticis 
nigris, intermediis et posticis flavis, duobus articulis 
ultimis atris. L. 0°0004; 1. 0:0012.” + 
The second species, whose habits were noticed by 
M. Herpin, was described by M. Guérin (Mem., p. 80) 
under the name of Chlorops Herpini, ‘‘ Flavicans; 
antennis nigris vel flavis, margine antico setaque nigris, 
vertice maculis duabus nigris triangularibus; thorace 
vittis tribus latis nigris ; abdomine fiavo, fasciis punc- 
tisque basalibus fuscis, ano nigro ; pedibus flavis tarsis 
omnibus fuscis. L. 0°008; 1. 0°001.”
