160 MALACODERMATA. 
36. Clerus zsopius. (Tab. VIII. fig. 8.) 
Niger, vix nitidus, sublevis, depressiusculus ; elytris fascia lata ad suturam anguste interrupta, ad marginem 
angustata, lineaque parva nec suturam nec marginem attingente flavis. Long. 8 millim. 
Hab. Nicaragua, Chontales (Janson). 
Deep black, short; thorax nearly as broad as the elytra at the base, with a scanty 
pile; the constricted basal part small. Elytra with rather prominent shoulders; a 
large, yellow, somewhat triangular spot nearer the base than the apex, nearly reaching 
the suture, and with one of its angles on the margin, but truncated there; and a very 
narrow: oblique line before the apex yellow. 
A single specimen, which has lost the abdomen, is all I have seen. It is very 
distinct. 
37. Clerus insidiosus. 
Niger, sericeus, pube cinerea fulvaque varius ; capite nigro, vix pubescente; prothorace elytrorum latitudine, 
cinereo-sericante, disco depresso; elytris tuberculo basali nigro-piloso, humeris subrugulosis, fascia 
mediana alba versus apicem recta, versus basin in medio elytri angulatim ampliata, apice indeterminate 
albo-pubescente ; pedibus (presertim posticis) longis. Long. 9-10 millim. 
Hab. Panama, Bugaba, David (Champion). 
This very singular insect resembles some of the varieties of C. mexicanus, and has, 
like it, a raised tubercle at the base of each elytron; but the length of the legs, espe- 
cially of the hinder femora and tibiw, remove it from any species of this genus, and 
perhaps indicate a generic difference, the hind femora being long enough to reach or 
pass the apex of the elytra. But the claws, antenne, palpi, and other characters are as 
in typical Cleri. | 
The antenne have the basal joint and the second joint partly reddish ; the palpi are 
black. The thorax is narrower behind and more produced than in C. meaxicanus or its 
allies, and hence appears more detached from the rest of the body; and this, together 
with the long legs, gives this species the appearance of the Australian genus Olesterus. 
The central fascia is white, bone-coloured in the middle, and thickly punctured and 
eburated at its edges; it is followed towards the apex by a band, nearly denuded, of 
the greenish-black colour of the base of the elytra; the apex is clothed with bone- 
white hairs. 
_ Two specimens were taken at Bugaba, and one at David, by Champion. 
38. Clerus cuneatus. (Tab. VIII. fig. 16.). 
Niger, parum nitidus, pube brevi plumbea vestitis, nigro-pilosellus, omnino crebre subtiliter punctatus; elytris 
fascia valde angulata alteraque recta spatium deltoideum nigrum cingentibus. Long. 8-10 millim. 
Hab. Mexico (coll. Gorham), Peras (Sailé). 
Black, nearly covered with a very fine, leaden, silky pubescence. The disk of the
