186 HEMIPTERA-HOMOPTERA. 
This species is one of the instances in which Stl totally ignores Walker’s description, 
although it is quite satisfactory; he has done the same with Monecphora postica, 
Walk.=T. pictipennis, Stal, and Sphenorhina assimilis, Walk.= T. varians, Stal. All 
three of these species are described by Walker as from Mexico (Sallé), and yet Stal, 
though he styles his papers “ Hemiptera Mexicana,” makes no allusion to any of 
them. 
7. simulans, so far as the formation of the metopidium is concerned, is intermediate 
between Monecphora and Sphenorhina, and serves to show how unsatisfactory a generic 
character this is. 
A specimen of the type form from Teapa is figured. 
26. Tomaspis prenitida, sp.n. (Tab. XI. figg. 23, 23 a, 6.) 
Oblonga, nigro-picea, nitida; capite sat lato, metopidio haud producto; pronoto latitudine fere duplo longiori, 
pernitido, levi, remotius punctato; scutello magno; tegminibus piceis, dense, antice fortius, punctatis, 
vitté subalbida undata pone scutellum, alteréque pone medium instructis, apice haud reticulato ; corpore 
subtus piceo, abdomine nigro; pedibus piceis. 
Oblong, broader in front than behind, the front parts very shiny; pitchy-black, with a whitish wavy band 
behind the scutellum and another behind the middle, the suture between these bands being lighter than 
the ground-colour; head broad; pronotum very shining, about twice as broad as long, diffusely and 
shallowly punctured ; scutellum large, brownish, produced into a sharp point behind; tegmina rather 
strongly punctured at the base, very finely so towards the apex, which is not reticulately rugose ;’ 
underside and legs pitchy, the abdomen black. 
Long. 84 millim.; lat. max. 34 millim. 
Hab. Panama, Volcan de Chiriqui 2500 to 8000 feet (Champion). 
27. Tomaspis apicifasciata, sp.n. (Tab. XI. figg. 24, 24a.) 
Parva, brevis, oblonga, nitida, nigra vel nigro-picea; capite brevi, sat lato, oculis permagnis, prominentibus ; 
metopidio haud producto, equali; pronoto longitudine sesquilatiori, sat fortiter punctato ; scutello 
leviter rugoso, peranguste albido marginato; tegminibus subtiliter punctatis, limbo albido sat lato, 
suturam attingenti, paullo ante apicem instructis ; corpore subtus pedibusque piceis. 
A small, short, oblong species, black, with a broad white band a little before the apex, reaching across the 
tegmina; head short, but broad, the eyes large and prominent, the metopidium not produced; pronotum 
shining, rather strongly and somewhat closely punctured ; tegmina very finely punctured behind, more 
evidently so in front, scarcely reticulate at the apex; legs pitchy. 
Long. 74 millim. ; lat. max. 4 millim. 
Hab. Panama, Bugaba (Champion). 
28. Tomaspis distincta, (Tab. XI. figg. 17, 17 a.) 
Sphenorhina distincta, Distant, Trans. Ent. Soc. Lond. 1878, p. 1781. 
“* Black, shining, thickly and finely punctured. Head, thorax, and scutellum slightly pilose. Reticulated 
portions of tegmina somewhat ferruginous; corium black, shining. Abdomen and posterior legs (tarsi 
excepted, which are black) sanguineous. Wings obscure hyaline, somewhat fuscous at outer borders. 
Posterior tibie armed with a strong spine. Scutellum large, transversely striated. Long. ex. tegm. 
6 millim.; exp. tegm. 18 millim.” 
Hab. Costa Rica, Volcan de Irazu 6000 to 7000 feet (Rogers').
