Géhin speaks only of **quelques poils rares;" because their form 
is notably shorter and wider than the form of Yarrelli, while 
Géhin seems to say that flavipennis is * narrower and longer than 
Yarrelli,—but it is not quite clear he may not mean that Yarrelli 
is narrower and longer than flavipennis (which is the more likely 
since Yarrelli is a particularly narrow and elongate species); and 
cause their sterna and hind coxe are variably (but always 
considerably) variegated with yellow, whereas in flavipennis they 
should be entirely green. The last-named discrepancy is of less 
consequence inasmuch as Géhin's description is evidently care- 
lessly written containing the statement that the “ ventre et bords 
posterieurs des segm abdominaux ” are of a beautiful green

being called a variety of Yarrelli as no variety of the latter 
(observed by me,—and I have seen many) much resembles it in 
markings, and the size (12—13 mm.) greatly increases the difti- 
mr of supposing it to be Yarrelli. Its author mentions having 
a good many specimens and the varieties he indicates are
