8. Liburnia teapa, sp.n. (Tab. XIII. figg. 13, 134, 6, 3.) 
Parva, partibus anticis nigris ; tegminibus nigris, nitidis, margine exteriore apicem versus vitreo-albido ; capite 
brevi, fronte latitudine fere duplo longiori, carina centrali valida, antennis sat longis, late flavis; pronoto 
brevi, carinis lateralibus haud basim attingentibus; scutello proncto triplo longiori, distincte tricarinato ; 
tegminibus venis granulatis; pedibus flavescentibus. 
Mas pygofero testaceo, tubé anali magn4, stylo anali fusco; stylis latis robustis, apicibus late dilatatis, 
furcatis. 
A very small species, with the front-parts black, more or less shining, the tegmina black, with the veins 
granulose, and the exterior margin towards the apex vitreous; forehead about twice as long as broad, 
with a strong central carina; antenne rather long, yellow; pronotum short, with the side-keels not 
reaching the base ; scutellum about three times as long as the pronotum ; abdomen piceous; legs yellow. 
Male with the pygofer broader below than above, with the anal tube large and the anal style large and 
fuscous ; styles broad, approximate, stalked, with a dilated head which is broadly furcate. 
Long. cum tegm. 24 millim.; lat. ad hum. 1 millim. (¢ @.) 
Hab. Mexico, Teapa in Tabasco and Vera Cruz (H. H. Smith). 
Several males and one imperfect female. 
4. Liburnia albolineosa, sp. n. (Tab. XIII. figg. 14, 144, 4, 3.) 
Precedenti quod formam pygoferi stylorumque maris maxime affinis, sed fronte angustiori latitudine triplo 
longiori, perdistincte tricarinata, carinis albidis, et vitté lata albida longitudinali a vertice usque ad 
media tegmina extensa, facile distinguenda. 
A very pretty species, black, with a clear white band running from the front to the middle of the tegmina, 
including the vertex and the central part of the pronotum and scutellum, and half the suture of the 
tegmina; the male characters are just as in the preceding species, except that the stalks of the styles are 
a little longer; this, however, is due probably to their being rather more adpressed in some specimens 
than in others; in the female the ovipositor is very large and strongly curved, and the side-plates are 
curved at the apex ; the forehead is very long and narrow, with three distinct white keels. 
Long. 23-3 millim.; lat. 1 millim. (¢ @.) 
Hab. Mexico, Teapa in Tabasco (H. H. Sinith). 
Several males and one female. 
5. Liburnia marginicornis, sp.n. (Tab. XIII. figg. 15, 15a, 2.) 
‘Testacea, pronoto apiceque abdominis supra et infra obscuriori; capite perbrevi, vertice ante oculos vix 
distincte producto, perbrevi, transverso; fronte angusta, latitudine fere triplo longiori; antennis sat 
longis testaceis, nigro, anguste sed distincte marginatis; pronoto brevi, carinis lateralibus haud basim 
attingentibus ; scutello magno, nitido, convexo, tricarinato, castaneo, macula fuscé utrinque pone medium ; 
tegminibus longis, flavo-pellucidis, ad medium indistincte notatis ; pedibus flavescentibus. 
Femina segmentis abdominis fortiter emarginatis ; ovipositore permagno, acuto.
