142 MALACODERMATA. 
3. Colyphus telephoroides. 
Ater, parum nitidus ; capite flavo, occipite et infra oculos nigro ; prothoracis lateribus angustius rufis. Long. 
6-8 millim. <6. 
Hab. Guaremara, Capetillo, San Gerénimo, Sinanja valley (Champion). 
In form and sculpture very nearly allied to C. ventralis; but the abdomen is wholly 
black, and the species is smaller. The specimen from San Gerénimo varies slightly in 
having the basal half of the lateral margin narrowly pale. 
4. Colyphus nigrifrons. 
Derestenus nigrifrons, Chevr. Rev. et Mag. Zool. 1874, p. 88°. 
Derestenus orthopieuridus, Thomson (Sallé coll. ex parte). 
Hab. Muxtco, Juquila, Cordova, Panistlahuca, Oaxaca (Sallé). 
The head and thorax are variable: in some specimens from Panistlahuca the former 
is entirely yellow and the thorax unspotted ; in other specimens the thorax has a central 
vitta ; in the type and specimens from various localities the thorax has a single spot on 
the front margin. The very evenly serrate antenne and yellow femora are good 
characters. The elytra are rather parallel, never vittate, but rarely with a shoulder- 
stripe ; the abdomen is black.’ 
5. Colyphus mutabilis. (Tab. VII. fig. 23, & Tab. VIII. fig. 1.) 
Derestenus mutabilis, Chevr. Rev. et Mag. Zool. 1874, p. 38’. 
Colyphus flammeus, Gorham, Trans. Ent. Soc. Lond. 1878, p. 162°. 
Hab. Mexico !?, Juquila (Boucard, coll. Sallé), Playa Vicente (Hoge). 
This differs in colour from C. nigrifrons; but it is variable; the typical specimens 
have the elytra yellow, with the apex and a scutellar spot black, and the disk of the 
thorax black. The femora are black. 
6. Colyphus lateralis. 
Derestenus lateralis, Chevy. loc. cit. p. 38°. 
Colyphus marginatus, Gorham, loc. cit. p. 162”. 
Hab. Mexico 12, Juquila (Boucard, coll. Sallé); Panistlahuca (Sad/é). 
The specimen from Panistlahuca is doubtfully assigned to this species; it has the 
breast yellow, as well as the legs, excepting the tibie and tarsi; and the submarginal 
stripe is rather further from the margin than in the two typical examples described by 
M. Chevrolat and myself. 
7. Colyphus floralis, (Tab. VII. fig. 25.) 
Niger, ore, antennis, prothorace (basi excepta), pectore pedibusque rufis; elytris flavo marginatis, vittaque 
angusta cum margine juxta apicem conjuncta flava. Long. 6 millim. 
Hab. Panama, Volcan de Chiriqui (Champion).
