POLYGLYPTODES.—ENTYLIA. 129 
2. Polyglyptodes affinis, sp. n. 
Precedenti affinis, sed flavo-testacea, longior et angustior, cornu pronoti longiori et rectiori, carinis utrinque 
rarioribus et magis elevatis ; pronoto ad latera fortius punctato, dorso fere recto, haud sinuato, lateribus 
minus rotundatis. — 
Allied to the preceding, but of a more yellowish-testaceous colour (which may be different in life), and evidently 
longer, narrower, and less robust. The horn of the pronotum is considerably longer, more slender and 
straighter, and has fewer and stronger carine at the sides. The back is almost straight throughout, from 
the tip of the horn to the apex of the pronotum, which is more strongly punctured at the sides, and has 
the coste, as a rule, more elevated, and the sides straighter, and is more gradually produced to a point 
both in front and behind, if viewed from above. 
Long. 10-104 millim. (sine cornu 8 millim.); lat. max. 1? millim. 
Hab. Mexico (Bilimek, in Mus. Vind. Ces.). 
Three female specimens. 
3. Polyglyptodes scaphiformis, sp. n. (Tab. VIII. figg. 11, 11a, 4.) 
Parva, elongata, angusta, fusca vel fusco-brunnea, capite metopidioque testaceis, pronoto in cornu breve, 
obtusum, utrinque carinatum, levissime deflexum producto, distincte minus fortiter punctato, plerumque 
undecim-costato, lined dorsali plus minusve elevata, interdum nigricanti, dorso a latere viso ab apice 
postico usque ad apicem cornus equaliter et leviter rotundato, haud sinuato; tegminibus hyalinis, venis 
fuscis ; pedibus testaceis, interdum ad partem fuscis, tarsis nigricantibus. 
A small species, which viewed from the side appears to be slightly and evenly rounded from the anterior to 
the posterior apex, like the shape of an inverted canoe; pronotal horn short and blunt and slightly 
deflexed, but straighter in some specimens than in others, with the sides carinated; pronotum rather 
finely but distinctly punctured, as a rule with five carinz on each side, dorsal carina more or less strongly 
elevated, sometimes blackish ; tegmina hyaline, with brownish veins; legs mostly testaceous, with the 
tarsi blackish. . 
Long. 6 millim. (sine cornu 5 millim.); lat. max. 13-14 millim. 
Hab. Guatemaa, Cerro Zunil (Champion). 
Five specimens. At first sight this species looks very different to the two preceding, 
but it cannot well be separated from them generically.

Entylia, Fairmaire, Ann. Soc. Ent. Fr. sér. 2, iv. p. 299 (1846) (nec Burmeister, Rev. Ent. Silb. 
iv. p. 181). 
The limits of this genus are very uncertain, and the synonymy is in great 
confusion owing to the variability of the species and the difficulty of distinguishing 
them by any constant characters. ‘They are, as a rule, easily recognized by the deeply 
cut sinuation of the pronotum, which is compresso-elevate and more or less sharply 
carinate ; the differences, however, in a large series of specimens are very great, and 
the gradation so complete that it is impossible to define the species with any approach 
to certainty. Stél separates off E. concava, Germ., under a separate genus Publilia, 
characterized by having the back of the pronotum convex and only slightly depressed 
before or at the middle; it is, however, doubtful whether the genus ought to stand,
