CAMPTODES. 347 
Group 4. 
Labrum broader, its lobes more truncate in front, forming an angle, with a minute 
denticle on each side of the median excision. Sides of the prothorax and elytra 
unarmed. (Species 48-51.) 
The species of this group are usually larger insects of less rotund form, and have the 
prosternal process comparatively more elongate. 
48. Camptodes latipes, sp. n. (Tab. XI. fig. 3, 3.) 
Rotundatus, minus elongatus, ferrugineus, elytris posterius ex parte majore nigris; pygidio peropaco, 
impunctato. 
Long. 57 millim. 
Hab. Panama, Bugaba (Champion). 
We have received only one male example of this species; it cannot be mistaken for 
any other of this group, as the form is that of C. communis, the elytra being less 
elongate than they are in its congeners, but by the structure of the labrum and 
mandibles the insect certainly belongs here. The surface is completely dull, as in the 
largest males of C. communis; the head is only finely punctured, the thoracic sculpture 
is completely obliterated, and the punctuation on the elytra can scarcely be detected ; 
the large black marks on the elytra are vague in front, do not reach the base, and are 
very widely separated at the suture anteriorly, but at the apex they leave only the 
margin ferruginous. The mesosternal carina is rather narrow. 
I suspect that the female of this insect will prove to be very different from the male. 
49. Camptodes chiriquensis, sp.n. (Tab. XI. figg. 4, 9; 4a, labrum and 
mandibles; 4 4, extremity of the elytra.) 
Rotundato-ovalis, sat. convexus, crebre subtiliter punctatus, nitidus, ferrugineus; pygidio crebre, subobsolete 
punctato. 
Long. 5-54 millim, 
Mas elytris subopacis, apicibus subtruncatis, angulo suturali leviter obtuso: abdomine segmento ultimo 
ventrali apice modice pubescente. 
Fem. elytris nitidis, apictbus subsinuatis, ad suturam breviter dehiscentibus. 
Hab. Panama, Bugaba, Volcan de Chiriqui, David, Caldera (Champion). 
Head coarsely punctate; club of the antenne fuscous, rather large. ‘Thorax rather 
closely and finely, the elytra sparingly punctate. 
We have received eighteen specimens of this species. Except in size, it varies little ; 
the sculpture in the males exhibits but little peculiarity; the sexual distinctions in the 
form of the apices of the elytra, though not great, appear to be quite constant.
