(especially behind) than in the allied species. The long series of examples before me 
vary in size from 93-14 millim. 
In Mr. F. Bates’s collection there is an example of this species labelled as from 
Mexico, and another Brazil (2); both localities require, I think, confirmation. 
Some allied undescribed species from Venezuela, Colombia, and Brazil exist in 
collections. 
2. Epitragus sallei. 
Epitragus sallei, Haag in litt. 
Oblong ovate, convex, reddish brown or piceous, shining, with very short scattered appressed yellow hairs, 
when fresh densely clothed with yellowish-white mealy efflorescence. Head closely and rather coarsely 
punctured, the epistoma rounded emarginate in front; prothorax broader than long, convex in front, 
widest at the base, the sides nearly straight behind, rounded and narrowing in front, hind angles subacute 
not prominent, anterior angles obtuse, the base bisinuate and with a shallow oblique impression on each side 
near the middle, closely and unequally punctured, the punctures fine and crowded at the sides and coarser 
and more scattered along the middle, and with a smooth central line; elytra wider than the thorax, convex, 
with rows of shallow grooves, in each of which are some scattered coarse punctures, the interstices very 
closely finely and confusedly punctured. 
Length 94-134 millim. 
Hab. Mexico (coll. F. Bates), Vera Cruz, Campeachy in Yucatan (Sallé); GuaTeMaLa, 
San Gerénimo, Paso Antonio (Champion); Nicaragua, Chinandega (Sallé).—Sovutu 
America, Peruvian Andes (coll. P. Bates). 
Narrower and a little more convex than LH. aurulentus; the thorax more convex, 
more rounded at the sides, the hind angles less acute, the punctuation unequal, and 
the pubescence less distinct. In some examples the thorax is a little narrower and 
more rounded at the sides than in others. 
3. Epitragus emarginatus. 
Closely allied to E. salle, and differing as follows :—The thorax is more equally and finely punctured, more 
rounded at the sides, nearly as wide at the base as the elytra, the punctures along the middle closer and 
finer, the basal impression on each side shallower and less distinct; the elytral grooves deeper, the inter- 
stices more finely and closely punctured. 
Length 9-11 millim. 
Hab. Panama, Volcan de Chiriqui, David (Champion). 
Fight examples. From EF. aurulentus it may be known by the thinner and less varie- 
gated pubescence of the upper surface, the narrower and more convex form, and the 
thorax less finely punctured and more rounded at the sides, with the hind angles more 
obtuse. An allied species from Carthagena is labelled E. lebasii, Dej., in Mr. F. Bates’s 
collection; E. fuscipes, Latr., from Colombia, must also be allied to this species. 
4. Epitragus nigricans. (Tab. I. fig. 18.) 
Ovate, rather broad, convex, blackish bronze, clothed with very fine, short, scattered appressed cinereous hairs. 
Head with the anterior margin and the vertex very finely and closely, and the space between the eyes
