I have abstained from giving a separate name to this- 
insect, because, in view of the great sexual differences of some 
Liparetri, and of the fact that the unique example described 
above is a male, while the unique type of analis is a female, 
I see nothing conclusive against their specific identity. The 
two specimens differ greatly in colouring, and the pygidium 
of analis is non-carinate. The hind tarsi of analh (type) have 
only the basal joint, but it is quite like the basal joint of the 
hind tarsi of the specimen described above. If further in- 
vestigation should prove that the male described above is dis- 
tinct from anafix, it will be time then to give it a separate 
name. The lidhitdt of the type of analis is uncertain. The 
fact that the basal joint of the hind tarsi is a trifle shorter 
than the second joint renders it desirable to compare it with 
the species of the third group, from all of which its nitid pro- 
notum bearing strong, decidedly sparse puncturation, in com- 
bination with its colouring and smaller size, readily dis- 
tinguishes it.
