MALACODERMATA.. 247 
Hab. Panama, Volcan de Chiriqui, Bugaba (Champion). 
Found in considerable numbers by Mr. Champion in company with C. oculatum, from 
which it could not have been discriminated when alive. It is apparently a commoner 
species. 
5. Calocladon ephippium. (Tab. XI. fig. 10¢,11¢.) 
C. oculato quoad formam congruens, nigrum; prothoracis lateribus elytrisque flavo-testaceis, his macula magna 
communi subtriangulari trienteque apicali nigris. Long. 8-9 millim. ¢ Q., 
Hab. Mexico, Cordova, Oaxaca (Hége); GuateMaLa, El Reposo, San Isidro ( Champion) ; 
Panama, Bugaba (Champion). 
The sexual characters, form of the thorax, and its carina and channel, agree with those 
of C. oculatum. The elytra have the alternate interstices equally raised. The black 
patch common to the elytra varies in size and a little in form. It usually widens out 
from the scutellum till it reaches the submarginal interstice, and it varies in the extent 
to which it is produced backwards or along the suture. A good series were obtained. 
The figures are from Bugaba specimens. 
LINOPTES, gen. nov. (to follow Calocladon, p. 29). 
Antenne utriusque sexus serrate, valid, compress, corpore breviores. Prothorax planiusculus tenuissime 
carinatus, carina postice duplici, vix divisa; basi valde bisinuata medio sublobato emarginata. Llytra 
cellulis seriebus decem instructis. 
This new genus differs from Calocladon in having the antenne of the male only 
serrate, and also in the shape and structure of the thorax and its carina, which is so 
very finely divided behind the middle as rather to give the idea of its being double in 
that part, the sides meeting again at the base. ‘The sexual characters of the abdomen 
are as usual; the seventh segment of the male is excised, showing a narrow conical 
eighth. 
I have considered whether this could be referred to Erichson’s genus Emplectus. I 
have not seen the typical species of that genus, viz. H. bimaculatus, a Peruvian insect. 
M. Bourgeois considers species which are very closely allied to the genus Calocladon of 
the present work to be referable to it; while Mr. C. O. Waterhouse refers to it 
Calopteron socium and allied species. I incline to the belief that an examination of the 
type will prove it to be different from any of these genera. 
1. Linoptes imbrex. (Tab. XI. fig. 12 ¢.) 
Depressus, postice paululum ampliatus, testaceus; capite, antennis, palpis, pedibus abdomineque plus minusve’ 
infuscatis; prothorax planiusculus antice angustatus, margine omni concinne reflexo, nitidulo, tenuiter 
carinato, carina pone medium tenuissime diviso, basi bisinuata angulis posticis acutis; elytris interstitiis 
alternis elevatioribus. Long. 11 millim. ¢ 9. 
Hab. Nicaracua, Chontales (Belt, ¢ ); Panama, Bugaba (Champion, 3 @ ).
