meanwhile it is practically impossible to draw a hard-and-fast line of difference between 
any of the forms. 
We figure a specimen of the form E. mira, Butl., from Orizaba.

One of the specimens from San Joaquin has the front horn almost wanting and the 
back of the thorax scarcely sinuate, and closely resembles a Publilia. 
PUBLILIA. 
Publilia, Stal, Ofv. Kongl. Vet.-Ak. Férh. 1867, p. 553. 
This genus was formed by Stal to receive Entylia concava, Germ., and is distinguished 
by having the back of the pronotum convex, only very slightly depressed in or before 
the middle. As above remarked, it is doubtful whether it will stand as a distinct 
genus from Entylia, although in facies it is very distinct from the ordinary forms of 
that genus.

In colour and general appearance closely resembling the preceding, but with a short and broad porrect horn in 
front, and with the back of the pronotum slightly sinuate and less straight before the horn; the colour 
is light brownish grey, with two more or less distinct lighter stripes on each side, and with a few very 
scattered small dark markings, which are often almost, if not entirely, absent.
