Hab. Mexico, Omilteme in Guerrero 8000 feet (H. H. Smith); Panama, Volcan de 
Chiriqui 8000 feet (Champion). 
Three female specimens. We figure one from the Volcan de Chiriqui. 
AMBLYCENTRUS, gen. nov. 
Oblongus, pubescens, capite insequali, ocellis inter se et ab oculis fere pariter remotis, oculis magnis prominulis ; 
pronoto convexo, supra caput late plicato, sine cornibus, humeris prominulis, a fronte visis subauriculatis, 
processu postico vix ultra apicem scutelli producto, obtuso, a latere viso sat lato apicem versus sensim 
dilatato ; tegminibus longis, pubescentibus, corio areis apicalibus quinque, discoidalibus duabus, clavo 
venis duabus magnis, distinctis; alis areis apicalibus quatuor ; pedibus teretibus. 
Elongate, strongly pubescent, with the head about as long as broad, and the eyes rather large; pronotum 
convex, rather strongly plicate above the head, without horns, with the shoulders prominent, and bounded 
on their inner side by a rather deep furrow, which makes them appear somewhat auriculate, if viewed 
from the front; posterior process reaching a little beyond the apex of the scutellum, not elevated above 
it, obtuse, if viewed from the side rather broad and gradually dilated behind ; tegmina long, pubescent, 
with five apical areas and two discoidal, the clavus with two large raised veins on the disc; wings with 
four apical areas; legs slender. 
This genus is rather closely allied to Centriculus, but the general facies is very 
different, and the longer head, subauriculate shoulders, and the very different tegmina, 
together with the two strongly raised veins on the clavus, seem sufficient to distin- 
guish it. 
1. Amblycentrus pubescens, sp. n. (Tab. IX. figg. 23, 23 a, 6.) 
Fusco-niger, capite pube longé densdque grisea instructo, pronoto fortiter punctato minus dense pubescenti, 
linea levi ferrugineé in processum posticum extenso, hoc brevi a latere viso haud tenui apicem versus 
sensim dilatato, testaceo, apice nigro; tegminibus ad basin nigris, punctatis, deinde nigro- testaceo- 
hyalino-variegatis, venis partim nigris, partim testaceis, his pube longa circumcinctis ; pedibus nigris, 
tibiis rufo-ferrugineo annulatis. 
Of a fuscous-black colour, with the head clothed with thick and long greyish pubescence; pronotum strongly 
and closely, and at the sides subrugosely, punctured, with a smooth central line extending behind into the 
posterior process, which is short, testaceous, and black towards the apex ; tegmina black and punctured 
at the base and thence variegated with black, obscure testaceous, and hyaline, the apex hyaline, the veins 
large, partly black and partly testaceous, surrounded by long pubescence; wings with the veins black; 
legs black, with the apex of the femora and tibie, the tarsi, except the claws, and more or less distinct 
rings on the tibie, rufo-ferruginous, 
Long. cum tegm. 53 millim.; lat. int. hum. 2 millim. 
Hab. Muxico (Mus. Oxon.: 2), Xucumanatlan in Guerrero 7000 feet (H. H. 
Smith: 3). 
This insect is quite distinct from any that I have yet seen. The specimen from 
Xucumanatlan is figured. 
Since writing the above description, I have received an insect from Omilteme, 
Guerrero (8000 feet), which may belong to this species; it is rather smaller, with the 
pronotal process narrower at the apex, and the apical areas rather straighter. Both 
this and the type specimen are males.
