united, the exterior one being in one instance disunited. The 
merest rudiments of punctures or strie remain. The scutellum is 
depressed at the base to receive the lobe of the thorax. It is 
difficult to compare this with any other species. It is, I think, best 
placed next B. distinctus. 
8. BRACHYSPHENUS BATESI, sp. nov. (Plate LXI. fig. 7.) 
Breviter oblongus, fere ellipticus, aterrimus, glaber ; elytris 
dimidio basali flavis, fasciis tribus e maculis irregularibus 
nigris formatis, prima basali valde undulata, secunda maculas 
quatuor punctiformes prebente, tertia e strigis sex obliquis 
plerumque constituta in singulis elytris. 
Long. 10-11 millim. 
Hab. Amazons (Bates). 
The form of this species is unusally convex; it is oblong, almost 
evenly wide before and behind, the extremity of the elytra being a 
little more pointed than the front. The surface is quite smooth in 
two specimens, in two others there is on the elytra very obsolete 
serial punctuation. The wavy fasciz on the yellow part of the 
elytra are variable, being very often formed, in the basal one, of two 
inverted V’s, thus 4 A, with a dot external and a linear mark internal 
to them. In the third fascia there are three V’s inverted, but the 
- linear spots are often all disunited; the margin of the black apical 
half is tridentate on each elytron. This is one of many beautiful 
species of Erotylide brought by Mr. H. W. Bates from the 
Amazons which have hitherto escaped recognition. Two specimens 
in Crotch’s collection and two in that of E. Armitage, Esq. It 
should be placed after B. musicalis. 
9. BRACHYSPHENUS INCAS, sp. nov. (Plate LXI. fig. 4.) 
Breviter ovatus, niger ; elytris tenuiter geminato-striato-punctatis, 
fasciis duabus ud suturam interruptis, una basali, una pone 
medium, epipleurisque flavis. 
Long. 11 miilim. 
Hab. Peru, Chancamayo. 
This insect resembles rather closely B. dizonatus, Crotch, and is 
allied to it by the geminate series of punctures and by the yellow 
epipleure ; it differs from it in being less convex, and by the form 
of the yellow fascize, which are not so broad; the anterior one is 
basal and is notched on its apical side, so as to appear somewhat 
arcuate ; the postmedial fascia is irregular on both its sides (but not 
dentate), rather narrower near the suture. The epipleure are 
yellow except in the apical quarter, and, as usual, the entire extremely 
narrow limb of the margin is black. 
This species also somewhat resembles B. epipleuralis, Crotch ; 
the geminate series of punctures will separate it. No metasternal 
nor abdominal lines are present. Three specimens, in my own 
collection.
