HYPAMASTRIS. 93 
1. Hypamastris segmentata, sp. n. (Tab. VI. figg. 23, 23 a, 3.) 
Sat lata, capite testaceo, pronoto leviter distincte punctato, sparsim pubescente, antice testaceo, postice fusco- 
brunneo, ad apicem interdum testaceo, vel macula aut vitté albida mox ante apicem, et macula semicirculari 
obscuriori utrinque ad marginem laterum arcu albido plus minusve distincté (nonnunquam deficienti) 
limitaté; dorso a latere viso leviter rotundato, vix sinuato, post medium impresso; tegminibus hyalinis, 
plus minusve infuscatis, macula infuscaté ad apicem, venis magnis brunneis; corpore subtus et pedibus 
testaceis unicoloribus vel ad partem fuscis. 
A broad and stout species, with the head and front part of the pronotum testaceous, the latter being dark 
behind, the change of colour being often gradual; at each side there is a dark semicircular patch usually 
bounded by a whitish arc, and there is usually a whitish vitta or patch before the apex, which is often 
obscurely testaceous; the pronotum is very closely and distinctly punctured, and evidently, though 
sparsely, pubescent, and is strongly impressed at the sides behind the middle; the tegmina, as well as the 
pronotum, vary in colour in different specimens, but are always more or less infuscate, and have an 
infuscate patch on the apical margin ; legs and underside testaceous, sometimes partly intuscate. 
Long. 4-5 millim. ; lat. int. hum. 2-22 millim. 
Hab. Mexico, Chilpancingo in Guerrero, Atoyac in Vera Cruz, Teapa in Tabasco 
(H. H. Smith); Guatemata, El Tumbador, San Isidro (Champion); Panama, Volcan de 
Chiriqui (Champion). | 
The colour of this species varies considerably, and some of the lighter specimens are 
almost unicolorous, but the darker arc at the side is almost always plainly traceable. 
Among the specimens from Teapa there is one variety with the ground-colour greyish, 
the dark markings of the pronotum very distinct, the sides of the body black, and the 
legs light testaceous. The specimen figured is from Teapa. | 
2, Hypamastris minor, sp. n. 
Minor, isabellina, minute griseo-marmorata, humeris testaceis; tegminibus hyalinis, fusco maculatis, venis 
distincte fuscis; pedibus testaceis. 
Considerably smaller than the preceding, of a dark fuscous or fuscous-brown colour, minutely marbled with 
greyish-brown, and with a minute obscure whitish spot on the central line behind the middle (sometimes 
absent) of the pronotum, and a small inconspicuous whitish band before the apex ; tegmina more or less 
broadly infuscate, with the veins thick and dark ; abdomen infuscate; legs testaceous. 
Long. 34-4 millim.; lat. 2 millim. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
A small series. 
3. Hypamastris albifrons, sp. n. (Tab. VI. figg. 24, 24.) 
Oblonga, depressa, magis parallela, fortius praecipue ad latera, punctata; capite metopidioque ad medium albidis 
purpureo-lineatis ; pronoto fusco-purpureo, carina centrali rufescenti, apice truncato ; dorso a latere viso 
fere recto, pone medium late leviter impresso; tegminibus hyalinis, venis maximis, irregularibus, fuscis, 
margine apicali fuscaté; corpore subtus pedibusque obscuris. 
Oblong, depressed, subparallel, with the sides very gradually narrowed to the apex of the pronotum, which is 
very blunt and truncate ; head and the centre of the metopidium whitish, with longitudinal purple 
lines; pronotum of a fuscous-purple colour, with the central raised line reddish ; dorsal surface almost 
flat, slightly but distinctly impressed on each side behind the middle; tegmina hyaline, with only the 
apical margin and the veins, which are very conspicuous, infuscate ; underside and legs dark. 
Long. 5 millim.; lat. int. hum. 23 millim. 
Hab. Guatemata, San Gerénimo 3000 feet (Champion).
