and furnished with from nine to a dozen fine coste on each side; the pronotal horn is broad at the base 
and has five or six coste on each side; tarsi occasionally somewhat darker than the rest of the legs. 
Long. cum cornu 13 millim.; ab oculis ad apicem pronoti 8 millim.; lat. max. 2 millim. (d 2.) 
Hab. Mexico (Bilimek). 
2. Bilimekia minor, sp. n. 
Duplo minor, cornu pronoti breviori, et lateribus utrinque sex- vel septem-costatis. 
Very like the preceding but very much smaller, with the pronotum rather more finely punctured and with 
fewer cost on each side, and the pronotal horn much shorter in proportion. 
Long. cum cornu 7-8 millim.; ab oculis ad apicem pronoti 43-5 millim.; lat. max. 14 millim. (d 9.)

POLYGLYPTODES, gen. nov. 
Polyglypte affinis, sed cornu pronoti a latere viso, ad basin latiori, et minus abrupte producto; capite sat 
magno, clypeo lato, modice semicirculariter exciso ; tegminibus areis tantum tribus apicalibus, undque 
discoidali, oblonga, prope apicem sita instructis. 
This genus is allied to Polyglypta and Bilimekia. From the former of these it may 
be distinguished by its finer sculpture and less abrupt horn (in which point, however, 
Polyglypta ague forms a transition between the two genera), and especially by the 
venation of the tegmina, which have only three apical areas, and the costal portion 
divided into three long basal areas instead of two asin Polyglypta. From Bilimekia 
it may at once be known by its shape and by the oblong discoidal cell of the tegmina, 
as well as by the fact that Bilimekia has only two long basal areas on its exterior 
portion, as in Polyglypta. 
The three species here described differ more or less in shape and general appearance, 
but agree in the generic characters above given. 
1. Polyglyptodes cucullatus, sp. n. (Tab. VIII. figg. 10, 10a, 8.) 
Elongata, robustior, tota testacea (an viridi-testacea ?), pronoto antice sinuatim in cornu breve, ad basin latum, 
ad apicem acutum, utrinque multicarinatum producto, dorso subrotundato, lateribus subparallelis in 
apicem obtusiusculum contracto, distincte et dense sed minus profunde punctato, undecim-costato ; 
tegminibus hyalinis, venis pallidis; pedibus testaceis. 
Elongate, but comparatively stout, of a unicolorous light testaceous colour, which is probably greenish in life ; pro- 
notum with the back slightly rounded, sinuate just above the shoulders, and produced into a short, porrect, 
moderately sharp horn, which is broad at the base and resembles a conical cap; at the sides of the horn 
there are several coste ; the sides of the pronotum are subparallel, very slightly rounded, and gradually 
contracted behind into a blunt apical process which reaches just as far as the apex of the tegmina; the 
punctuation of the pronotum is close and distinct, but not coarse, and on each side there are five or six 
fine but distinct coste ; the latter character, however, is variable, and one specimen before me has five on 
one side and six on the other; legs testaceous. 
Long. 8 millim. (sine cornu 6 millim.); lat. max, 2 millim. 
Hab. GuaTEMALA, near the city (Champion). 
Three specimens.
