and the fascia very much reduced. All the forms agree in the general disposition of 

 the markings, and nearly so in puncturing.

Possibly this is another variety of E. ocellatus, to which it corresponds in its 

 markings; it is, however, always darker yellow, less pubescent, broader, and less 

 parallel. The district of its distribution is the northern limit of the genus. 



3. Epopterus comptus. (Tab. vil. fig. 20, d .) 



Oblongus, rufo-piceus, nitidus, antennarum basi pedibusque flavis, illis articulis sex ultimis nigris ; prothorace 

 transverso, lateribus sinuatis antice parum attenuates, angulis posticis acutis, maculis tribus basalibus 

 elongatis duabus anterioribus ssepe confluentibus et plagia laterali antice abbreviata nigris ; elytris flavis 

 vel ferrugineis, maculis duabus (una basilari, una subapicali) fasciaque lata utrinque valde undulata nigro- 

 piceis, sutura postice parum infuseata. Long. 6 millim. $ $ . 



Hab. Nicaragua, Chontales (Janson, Belt). 



Allied to E. ocellatus, but distinguished from any of the varieties of that species 

 known to me by the marking of the thorax : the four transverse spots are, as it were, 

 united by streaks to the base, with the addition of two on the front margin, which are 

 often confluent, and have each an angular projection inwards, and one central basal 

 one. The markings of the elytra are also different, as there are but one basal and one 

 apical spot, the latter being large, and there is no spot on the suture ; the suture is in 

 some cases pitchy-red in the centre of the fascia. The elytra are more convex in the 

 longitudinal direction than in the allied species, with the least appearance of pubescence 

 at the margins and apex, very finely, but distinctly, punctured. The legs are rather 

 long, entirely yellow; the male characters, as usual, not very pronounced. 



There are four specimens of this insect collected by Janson and one by the late 

 Mr. Belt before me, which do not vary among themselves to any extent. It is a species 

 which will compare favourably for beauty with any in this genus. 



A male specimen is figured. 



4. Epopterus scalaris. (Tab. vil. fig. 21.) 



Oblongus, latiusculus, niger, nitidus ; capite, prothoracis macula quadrata ad angulum anticum, ramum postice 

 emittente, elytrisque flavis, his sutura antice late, fascia mediana undulata, puncto subhumerali, apiceque 

 nigris ; abdomine versus apicem tarsisque flavescentibus. Long. 6J-7 millim. $ <j> . 



Mas tibiis anticis curvatis, ad apicem rectis, et compressis. 



Hab. Nicaragua, Chontales {Belt) ; Panama, Bugaba, Volcan de Chiriqui (Champion). 



Head yellow, rather thickly punctured ; antennse black. ' Thorax smooth, sparsely 

 and rather deeply punctate ; the basal sulci sharp and clear, starting from triangular
