26 HETEROMERA. 
6. Epitragus ornatus. (Tab. I. fig. 20.) 
Oblong ovate, rather broad, brassy seneous, clothed with cinereous pubescence. Head rather short, closely and 
finely punctured, epistoma produced and rounded in front; prothorax—in the female broader than long, 
narrowing from the base forwards, the lateral margins sinuate (not straight) thickened and reflexed and 
abruptly narrowing in front, the base bisinuate, the disc with an oblique ridge on each side extending to 
the anterior margin (which is a little raised and feebly emarginate between) and enclosing a large 
flattened shield-shaped impression, the elevations a little thinner in front and each with a tuft of yellowish 
decumbent hair, the anterior angles acute, prominent, and parallel, the hind angles thickened and subacute, 
with a deep rounded excavation on each side near the base, smooth, shining, very finely and sparingly 
punctured, sparingly pubescent,—in the male about as long as broad, very slightly rounded at the sides, 
closely and finely punctured, with a smooth central line, and the base with a feeble oblique impression on 
each side just within the margin; elytra short, broader than the thorax, scarcely narrowing behind, very 
closely, finely, and equally punctured. 
Length 12-123 millim. (¢ 9.) 
Hab. Mexico, Matamoras, Puebla (coll. F. Bates), Izucar, Guanajuato (Sal/é). 
Six examples. I have seen this species labelled E. acutus, Lec. ‘The female of 
E. ornatus may be known at once by the tufts of yellow hair on the front of the thorax. 
7. Epitragus hogei. 
Oblong ovate, brassy with a cupreous tinge, clothed with yellowish or cinereous pubescence. Head closely and 
finely punctured, the vertex in the female with two broad shallow longitudinal impressions separated in 
the middle by a fine indistinct ridge, the epistoma produced and rounded in front; prothorax—in the 
female transverse, the sides straight, narrowing from the base forwards, the lateral margins a little 
thickened and reflexed, the front angles rather prominent, acute, and directed a little inwards, the hind 
angles acute but not very prominent, the base feebly bisinuate, with a smooth shallow central line or 
channel, the disc raised towards the front, flattened and excavated within, enclosing a shallow triangular 
impression, closely, finely, and equally punctured, rather shining,—in the male less transverse, more 
closely and distinctly punctured, the disc very slightly flattened [not excavated], and the prominent anterior 
angles broader and triangular; elytra wider than the thorax, very closely and finely punctured, with 
indistinct traces of shallow fine grooves. 
Length 12-123 millim. (¢ 2.) 
Hab. Mexico, Misantla, Jalapa, Cerro de Plumas (Hoge). 
Nine examples, of which seven are females. The male of this species may be known 
from that sex of FE. bicarinatus by the thorax being less widened at the base, the front 
angles broad and triangular, and the hind angles less acute and not produced; the 
female is abundantly distinct. 
8. Epitragus angusticollis. 
Oblong ovate, brassy neous, somewhat densely clothed with cinereous pubescence. Head closely and finely 
punctured, the epistoma produced and rounded in front; prothorax broader than long, comparatively 
narrow, Widening but little behind, the lateral margins equally thickened and reflexed from base to apex, 
almost straight, the anterior angles are much produced, very prominent and acute and directed a little 
outwards, the hind angles obtuse not prominent, the base feebly bisinuate, with a smooth central line, the 
disc raised in front and with a rounded elevation on each side, shallowly impressed at the base and near 
the anterior margin, closely and finely punctured; elytra much wider than the thorax, closely and very
