separated, but in Amphideritus there is a post-coxal process that is not found in 
Deamphus. 
1. Deamphus brevipennis, sp.n. (Tab. V. fig. 1.) 
Niger, tenuiter setosus, antennis piceis ; prothorace valde transverso, lateribus rugosis, disco punctato, nitido * 
elytris seriatim fortiter, minus argute punctatis. 
Long. 62 millim. 
Hab. GUATEMALA, Quezaltenango 7800 feet (Champion). 
Rostrum short, coarsely and closely punctate, shining, rather deeply impressed along 
the middle, with a fovea between the eyes; the latter a little convex. Thorax broad, 
close. to the front abruptly narrowed, and also much narrowed near the base, the 
basal margin distinct; rugose-punctate, except on the disc, where the punctuation is 
more scanty. Elytra short, with series of coarse, but not deep punctures. Legs 
elongate. One specimen. 
This species is not much like any other known from our region. It somewhat 
resembles Peritaxia rugicollis, Horn, though that is a much more elongate insect. 
2. Deamphus deceptor, sp. n. 
Nigro-piceus, nitidus, parce setosus, in elytris submaculatus; prothorace fortiter rugoso; elytris profunde 
grosseque seriatim punctatis. 
Long. 7-8 millim. 
Hab. GuatemaLa, Quiche Mountains 7000 to 9000 feet, San Gerénimo 3000 feet 
(Champion). | 
| Closely allied to D. brevipennis, but with a much coarser sculpture on the thorax ; 
the surface bears a scanty depressed setosity of a pinkish-grey colour, and on the elytra 
these scale-like sete are more abundant in some places, so as to form a vague pattern. 
In the male the thorax is rather more dilated at the sides than it is in the female. 
Six specimens. | 
3. Deamphus latifrons, sp.n. (Tab. V. fig. 2.) 
Gracilis, elongatus, piceus, squamosus parciusque setosus ; elytris punctato-striatis. 
Long. 11-12 millim. 
Hab. Mexico, Hacienda de San Miguelito (Dr. Palmer), Refugio in Durango (Héqe). 
Evenly covered with round, closely-adherent scales of a greyish or ashy colour, these 
scales nowhere overlapping one another ; the surface also bears fine, rather long, scanty 
hairs. Rostrum very short and broad, separated from the head by a broad obscure 
depression, in which there is placed an indistinct fovea; eyes very widely separated, 
round, rather convex ; antenne dark red, setose. Thorax strongly transverse, rounded 
at the sides, rather narrower at the base than in front, quite even, and without basal
