626 SEEEICOENIA . 



TELON. 



Head short, not produced in front, in repose resting upon the prosternum and invisible from above, sunk into 

 the prothorax up to the eyes, the latter very large, rounded, and prominent ; labrum very broad, short, 

 prominent; mandibles acute, short, stout, curved, projecting beyond the labrum, armed with a sharp 

 tooth on the upperside some distance before the apex ; mentum broad, strongly transverse, narrowed in 

 front ; ligula in the form of two loug tapering lobes ; maxillary palpi very stout, the apical joint subsecu- 

 riform ; labial palpi long and stout, the second joint elongate, the third joint subsecuriform ; outer lobe 

 of the maxillae divided into two, the outer portion long and tapering, the inner portion short, both being 

 ciliate, the inner lobe rather slender ; antennae with joint 1 stout, 2 very small, the other joints long and 

 flattened, 3-10 very broadly and obliquely dilated within, with their inner apical angles obtuse ; pro- 

 thorax completely margined at the sides, semicircular, transversely swollen in front ; scutellum trans- 

 versely cordate ; prosternum extremely short and vertical before the coxse, and produced between them 

 into a thin lamella, which is raised almost to the level of the coxse, hooked at the tip, and received into a 

 deep notch in the mesosternum ; anterior coxse oval, with large trochantin ; middle coxse narrowly 

 separated, with small trochantin ; posterior coxse separated by a narrow intercoxal process, the coxal 

 plates moderately dilated inwards : legs stout, the tibial spurs small : tarsi shorter than the tibiae, the 

 basal joint about as long as the second and third united, the third joint broadly dilated, excavate above, 

 and extending to some distance beneath the fifth, its lower surface velvety-pubescent, the fourth joint 

 very small, the claws feebly dilated towards the base ; sixth ventral segment visible. 



The above characters are taken from a single species of large size from Panama. 

 This insect, which has very much the facies of a Lampyrid, is nearest allied to 

 Cladotoma, Guer., a genus containing three Tropical- American species ; but differs 

 from it in the bilobate ligula, the bilobed outer portion of the maxillae *, the shorter, 

 subsecuriform apical joint of both palpi, &c. The antennae might be described as 

 broadly lamellate. The form of the tarsi agrees with that of the Ptilodactylini, except 

 that the claws are only feebly dilated towards the base. 



1. Telon CUCullatUS. (Tab. XXVII. figg. 14 ; 14 a, labium ; 14 b, maxilla and 

 maxillary palpus ; 14 <?, antenna.) 



Broad, robust, oblong-oboval, subopaque ; rufo-luteous, the eyes, the antennas, the basal joint excepted, the 

 palpi in great part, and the apical three-fourths of the elytra, black ; beneath luteous, with the abdomen, 

 except at the base on either side, black ; the legs luteous to the basal third of the tibise, the rest of the 

 tibiae and the tarsi black ; above and beneath densely, minutely punctate, and thickly clothed with very 

 short fine pubescence, which partakes of the ground-colour, except on the abdomen, where it is fuscous. 

 Head with indications of a smooth median line ; antennae about half the length of the body. Prothorax 

 transverse, semicircular, bisinuate at the base, with the broad median lobe truncate ; obsoletely canali- 

 culate, and with two transverse depressions behind connected by a transverse groove ; the basal margin 

 bisinuate, finely denticulate. Scutellum finely denticulate in front. Elytra wider than, and four and 

 one-third times the length of, the prothorax, widening to beyond the middle, compressed at the sides 

 below the humeri, and sharply margined, with indications of four faint costae. Fifth ventral segment 

 entire. 



Length 13, breadth 6f millim. 



Hal. Panama (Salle). 



One example, probably a female. The locality seems to require confirmation. 



* In Cladotoma the ligula and the outer portion of the maxillae are both quadrilobate.
