276 SUPPLEMENT. 
8. Cometes hilaris. (Tab. XIX. fig. 25.) 
C. acutipenni (Buquet) simillimus ; differt capite angusto post oculos haud subito angustato, ventre sparsim sub- 
tilissime setifero-punctulato. Angustus, gracilis, viridi-cyaneus ; elytris vix nitidis versus suturam violaceis, 
fascia basali aurantiaca ; capite post oculos quadrato apud collum angustato ; thorace grosse subconfluenter 
punctato, callis quinque dorsalibus levibus; elytris postice attenuatis apice sat prolongatis subacutis, 
undique confertissime grosse punctatis, costula utrinque tenuissima; corpore subtus subtilissime sparsim 
setifero-punctulato. 
d(?). Ventris segmento apicali plano, medio foveato, apice angustato et rotundato. 
Long. 44 lin. 
Hab. Panama, Bugaba (Champion). 
Very similar in form and colours to the C. acutipennis, Buq., of Cayenne, but differing 
in the form of the head and the punctuation of the abdomen. In C. acutipennis ( ¢ ) 
the head is narrowed immediately behind the eyes, which latter are prominent, and the 
abdomen is very closely and coarsely punctured. If the two examples of C. hilaris are, 
as I believe, males, they offer further a great difference from the same sex of C. acuti- 
penms in the terminal ventral segment, which in C. acutipennis is greatly elongated, 
semitubular, and broadly truncated at the apex*. 
4. Cometes festivus, (Tab. XIX. fig. 24.) 
C. pulcherrimo affinis; differt elytris utrinque maculis magnis cuneiformibus duabus aurantiacis, altera basali 
altera apicali. Viridi-eneus, capite angusto, post oculos tumido; thorace grosse subconfluenter punctato, 
callis quinque levibus; elytris apice subacute rotundatis undique confertissime grosse punctatis, sub- 
tiliter costatis, maculis basali postice, apicali antice, versus discum prolongatis, subacutis. 
dS. Palpi maxillares articulo apicali valde et oblique dilatato, campanuliformi, apicis concavitate latissima ; 
ventris segmento apicali parvo, plano, apice subemarginato. 
9. Palpi maxillares articulo apicali ovato, apice acuminato. 
Long. 4—63 lin, 
Hab. Panama, Bugaba (Champion). 
5. Cometes venustus. (Tab. XIX. fig. 23.) 
Elongatus, subviridi-cyaneus ; elytris fulvo-aurantiacis, plaga utrinque elongata laterali (apud medium) violacea; 
capite post oculos gradatim paullo angustato; thorace grosse punctato-ruguloso, 5-calloso; scutello 
cyaneo; elytris apice oblique obtuse truncatis, confertim grosse (versus basin subseriatim) punctatis, uni- 
costulatis ; femoribus postice apice bispinosis ; ventre grosse sed valde sparsim punctato. 
@. Palpi maxillares articulo apicali ovato. 
Long. 6 lin. 
Hab. Panama, Bugaba (Champion). 
* T profit by this occasion to correct an error in the remarks on C. acutipennis and on the genus Heteropalpus, 
which I published in Trans. Ent. Soc. 1870, p.441. I there say that the ¢ of C. acutipennis has the singular 
form of maxillary palpi which characterizes the genus Heteropalpus, the 9 having normal palpi, and that this 
genus is therefore untenable. The pair of C. acutipenmis received from Paris, labelled as such, on which the 
above remark was founded, I now find to be both males, and, notwithstanding the identity of colours, to 
belong, the one (the true C. acutipennis, Buq.) to Cometes, the other to Heteropalpus.
