STELIDOTA. 315 
punctuation very obsolete; with regular series of erect short pubescence, each series 
consisting of a single row, but midway between each pair with an indistinct series of 
shorter hairs; costate at the apex only; fuscous, with the apex, a spot at the base of 
each, and another beyond the middle vaguely red. Under surface more or less infuscate. 
Axillary space large, the coxal line being externally greatly deflexed. Male with the 
hind tibize almost simple, very slightly curved and feebly dilated at the apex. 
We have received a good series of this inconspicuous insect. 
14, Stelidota championi, sp. n. (Tab. X. fig. 6, 2.) 
Minor, oblongo-ovalis, minus lata, convexa, ferruginea, elytris fuscescentibus, ad basin et ultra medium vage 
ferrugineis ; prothorace basi fere truncata, lateribus haud explanatis ; elytris obsolete sculpturatis, tantum 
ad apicem sulcatis, seriatim regulariter pilosis.

Smith); Guaremaa, Capetillo, San Gerdénimo, San Juan in Vera Paz (Champion) ; 
Panama, Bugaba (Champion). 
This species closely resembles S. chontalensis, but it has the axillary space small, 
and the male has the hind tibie simple, and straight even along the inner margin. The 
thorax is not quite so free from curvature at the sides as it is in S. chontalensis, and the 
base is perceptibly sinuate on each side near the angle. 
15. Stelidota extranea, sp.n. (Tab. X. fig. 7, 2.) 
Oblongo-ovalis, subdepressa, fusca, supra fusco-testacea, limbo testaceo; prothorace lateribus late explanatis ; 
elytris irregulariter, fortiter, parum profunde, punctatis. 
Long. 3% millim.

Although very dissimilar in appearance from the typical species of the genus, this 
insect shows no remarkable structural differences, the most important being, so far as I 
can see, that all the coxe are less widely separated ; the sculpture of the upper surface 
and the form of the thorax are the characters that give rise to its peculiar facies. The 
thorax is very deeply emarginate in front, the base is quite straight, the hind angles 
definite, slightly obtuse, the sides expanded, the surface a little uneven, coarsely but 
not at all deeply punctate. Scutellum triangular. LElytra fuscous on the disc, 
but vaguely marked with yellow, which is the predominant colour at the margins; 
the surface is coarsely punctate, and there is a very scanty irregularly distributed 
pubescence. The male has the apices of the middle and hind tibie a little incurved. 
Two specimens.
