186 MALACODERMATA. 
The one from Pantaleon is so very small that it seems difficult to connect it with 
the same species. I do not think; this insect is the same as the species from Cuba 
which Chevrolat regards as the 0. bimaculata of Melsheimer. It is, at any rate, 
distinct from O. damicornis, and is very much more pubescent. 
4. Orthopleura purpurea. (Tab. IX. fig. 17.) 
Rubra, pube micante vestita ; antennis, palpis, thoracis lateribus, pedibus et abdomine nigris. Long. 5-10 millim. 
Hab. Guatemata, Chacoj (Champion). 
The specimens taken at this locality, nine in number, all agree in presenting a very 
distinct form of coloration. This species is no doubt very closely allied to O. binotata ; 
but there are no connecting forms, and I believe it will prove distinct. ~The antennz 
are nearly twice as long as the head and thorax. The thorax is indistinctly carinate, and 
with an obsolete tubercle behind. The pubescence is velvety and shining, disposed in 
three lines on the thorax. The species of this genus vary very much in size, probably 
not so much in colour. 
5. Orthopleura ichnoides. 
Platynoptera ichnoides, Chevy. Rev. et Mag. 1874, p. 73’. 
Hab. Mexico, Cordova ! (Sallé). 
It is odd that the affinities of this insect did not strike M. Chevrolat; but it is never- 
theless a veritable Orthopleura. The antenne are longer than usual; and the thorax 
has two black lines in addition to the sides being black in the normal manner. 
Two specimens are all that were in Sallé’s collection when it was acquired by the 
editors. 
6. Orthopleura teneroides. | 
Oblonga, subcylindrica, nigra, subopaca, capite obscure rufo, prothorace rufo, vitta mediana integra lateribusque 
ad angulos anticos nigris. Long. 7-11 millim. 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). 
The smaller specimens of this species, probably the males, are much narrower than 
the larger ones, which also have the ventral apical segment elongate spathulate. The 
head is obscurely red between the eyes. The thorax is clothed with sericeous hairs, which 
are red on the rufous portion; the sides beneath and a rather wide vitta extending from 
the front to the hind margin are black. The elytra are distinctly punctured, the punc- 
tures being close, very irregular in shape, and the interspaces dull. The antenne are 
_of ordinary length ; the intermediate joints as in O. purpurea &c., set with strong tufts 
of black hairs, and the three terminal joints about equal in length to the basal part. 
Five specimens from Bugaba, one from Chiriqui.
