ENCHENOPA. | 11 
7. Enchenopa multicarinata, sp. n. 
Castaneo-ferruginea; capite modico subquadrato, pronoto subtiliter griseo-pubescenti in cornu longum et sat 
latum utrinque quinque-carinatum producto; tegminibus subhyalinis, venis brunneis; pedibus rufo- 
brunneis. 
Elongate, castaneo-ferruginous, with the pronotum finely pubescent and closely punctured, produced into a horn 
which is longer than the remainder of the pronotum, and forms almost a straight line with it, and is broad, 
_ rounded at the tip, and furnished with five more or less distinct carinew on each side; lateral carine 
strongly marked; tegmina brownish, darker towards the base, slightly mottled, coloured much as in the 
preceding species; legs ferruginous. 
Long. 94 millim., cam tegm. 103; long. cornus 5 millim. 
Hab. Mexico (coll. Signoret, in Mus. Vind. Ces.). 
This species resembles £. sericea, but may at once be distinguished by the much 
longer pronotal horn, which is furnished with more carine, by its finer pubescence and 
the colour of the tegmina.

The single specimen contained in the ‘ Biologia’ collection is much larger (long. 11 
millim.) than a typical specimen sent me by Dr. Aurivillius, and is darker coloured; I 
cannot, however, find any structural difference sufficient to give it specific value. The 
slender form and very long thin thoracic horn at once distinguish the species from any 
other I have seen.

This is a very puzzling species, and appears to present several different forms; the 
extreme varieties look very different, but in a large series they lead one into another 
by a perfect gradation. I thought at first that two species at least might be sepa- 
rated on the presence or absence of the pronotal horn, but in some specimens it is 
well marked, though short, in others it is rudimentary, and in others entirely absent: 
the colour, too, is variable ; the upper surface of the pronotum is black or more or less 
ferruginous with two light markings, one dorsal and one just before the apex; at the
