of squamosity, but that is really clothed with inconspicuous scales. It is of compara- 
tively narrow and elongate form, and is also distinguished by the regular coste, which, 
however, are not strongly elevated, and by the numerous and closely placed large 
punctures on the spaces or intervals between them. The thorax has the groove 
along the middle entire, rather narrow, the lateral sculpture scanty, and not forming 
a continuous depressed space. 
Two specimens from Sallé’s collection are labelled “ Epicwrus niger, Chevr.;” a 
mutilated example in my own possession is labelled “ H. aléernans, Jekel.” 
6. Epicerus centralis, sp. n. 
Elongatus, niger, tenuiter squamosus ; elytris interstitiis 3°, 5°, 7° parum elevatis; prothorace haud discrete 
sulcato; rostro medio canaliculato. 
Long. 12-14 millim. 
Hab. Mexico, Guanajuato (Sallé). 
I distinguish from Z. vilis four individuals of more elongate form, with a greater 
amount of pallid squamosity on the surface, and with the raised coste of the elytra 
less definite. They are separable from E. cognatus by these characters, and by the 
rostrum having on the middle only a single groove. The thorax bears numerous 
coarse rugosities, but exhibits no definite sulcus along the middle, though the rugosities 
there are more continuous and confluent than elsewhere. The sculpture between the 
slightly elevated coste of the wing-cases is coarse and deep, though indefinite. 
Three males and one female. The female example is much larger and broader than 
the males. 
7. Epicerus zqualis, sp.n. (Tab. IV. fig. 20.) 
Elongatus, niger, obsolete squamosus ; prothorace ubique rugoso, medio sulcato; elytris profunde regulariter, 
fortiter seriatim punctatis, interstitiis alternis vix magis elevatis ; rostro trisulcato. 
Long. 17 millim. 
Hab. Mexico, Orizaba (Sal/é). 
Although we have received only one example, a male, of this species, it appears to 
be readily distinguished from all others of the genus by the sculpture of the elytra 
consisting of very large, regularly-placed punctures, while the alternate interstices are 
only very obscurely elevated. The rugose punctures of the thorax are evenly distributed, 
so that there is no trace of lateral impressions, although the median groove is quite 
distinct. ‘The three grooves on the rostrum are very distinct. 
8. Epicerus uniformis, sp. n. 
Niger, dense, pallide griseo-squamosus ; elytris interstitiis 3°, 5°, 7° sat elevatis, 7° nudo; prothorace rugoso, 
vix in medio sulcato ; rostro medio canaliculato. 
Long. 13 millim. 
Hab. Mexico, Puebla (Sallé).
