498 COLYDIIDA.—RHYSODIDZ. 
very different appearance from Holophygus, yet the two genera are apparently very closely 
allied structurally. Notiophygus has, however, very thick maxillary palpi, while the 
parts of the mouth in Holophygus, so far as I can see them, apparently differ but little 
from those of Discoloma. 
1. Holophygus celatus, sp. n. (Tab. XV. fig. 29.) 
Subrotundatus, sat convexus, fuscus, limbo rufescente ; antennis pedibusque flavis; opacus, breviter parceque 
hispidulus, limbo subtuberculato. 
Long. 23 millim. 
Hab. Panama, Volcan de Chiriqui 3000 feet (Champion). 
Club of antenna elongate and slender. Head small, deeply inserted in the thorax ; 
this latter broad and short, very greatly narrowed in front. Scutellum extremely short. 
Elytra as well as the thorax coarsely, quite irregularly punctured, and studded with 
distant, very short, thick, erect sete; the margins of the thorax as well as those of the 
elytra are so formed as to give an undulated outline to the insect, the projections on 
each wing-case being seven in number. 
Of this curious little insect only one specimen was obtained, and it, unfortunately, has 
been somewhat injured, probably in connection with its capture. 
Fam. RHYSODIDZ*. 
According to the Catalogue recently made of these anomalous insects by Mr. Geo. 
Lewis, forty-one species are at present known. One only has been previously recorded 
from our region, and I now add a second discovered by Mr. Champion in Guatemala. 
CLINIDIUM. 
Clinidium, Kirby, Zool. Journ. v. p. 6 (1829). 
This genus, consisting at present of sixteen species, has an extremely wide distribution 
in both hemispheres. C. guatemalenum is found under the bark of pines. 
1. Clinidium mexicanum. 
Clinidium mexicanum, Chevr. Ann. Soc. Ent. Fr. 1878, p. 214°. 
Hab. Mexico, Jacale (Sallé}, Truqui), Cordova (Sallé), Omilteme in Guerrero (H. H. 
Smith), Las Vigas, Esperanza, Amecameca, Toluca (/oge). 
9. Clinidium guatemalenum, sp. n. 
Angustum, nigro-piceum, nitidum; prothorace lateribus bisuleatis, dorso profunde sulcato, basi utrinque foveolata, 
foveolis longe antrorsum prolongatis ; elytris sulcatis, interstitiis minus argute crenatis. 
Long. 7-8 millim.
