Jasciisque duabus denticulatis, una mediana ad suturam inter- 
rupta, una subapicali arcuata luteis ; antennis articulis duobus 
primis exceptis, tibiis tarsisque nigro-fuscis. 
Long. 12 millim. 
Hab, Peru, R. Ucayali (Bartlett). 
Var. prothorace nigro-marginato, punctis duobus externis cum 
margine conjunctis, elytris macula parva humerali et epipleuris 
basi fulvis. 
Hab. Amazons (Bates). 
Head and thorax forming a nearly even semicircle in front, the 
latter being excised deeply, but not widely, for the reception of the 
former, both of a uniform rich orange-red ; in the typical examples 
from Ucayale only the extreme limb, and this so narrowly as not to 
be apparent, is blackish. The ten spots are placed, four trans- 
versely in front, and six in a row behind these, the three on each 
side being arcuate, the four central ones forming a square. The 
scutellum is either rufous or pitchy. The elytra are evenly 
punctate-striate, the rows of punctures very finely impressed, the 
interstices smooth and shining. The underside wholly of the rich 
red colour of the head and thorax. The metasternal and abdominal 
lines both very fine and short. The prosternum is compressed, 
forming a blunt keel, a very little prominent in front. The elytral 
fascize are yellow, the basal markings more orange-coloured. The 
first fascia commences rather before the middle of the margin, but 
is oblique, reaching the suture about the middle ; it has two or three 
irregular teeth on each side. The epipleuree are quite black in the 
typical examples. The legs are of the body-colour, with black tibize 
and tarsi; in the variety the tibiee are rufous at their tips. 
In the Amazons specimens the limb of the thorax is more 
distinctly black, and on the middle of the front has a triangular 
black spot, and on the base three such spots attached to it, the two 
exterior discoidal spots also being united, so that the six remaining 
spots form two equilateral triangles; the wide concave part of the 
epipleura is yellow. Four specimens of the typical form from Mr. E. 
Bartlett, and two of the variety from Crotch’s collection, and two 
others from the Amazons in the collection of E. Armitage, Esq. 
7. BRACHYSPHENUS BISTRIFOLIATUS, sp. nov. (Plate LXI. 
fig. 5.) 
Late ovatus, ater, nitidus ; elytris perobsolete punctato-striatis, 
singulis macula magna trifoliata basah, fasciaque lata, ad 
suturam interrupta, pone medium aurantiacis. 
Long. 13 millim. 
Hab. Peru, Chancamayo (Buckley). 
Labrum and palpi yellow; head and thorax smooth, the latter 
glabrous, twice as wide as long at the base, the front narrower, the 
basal median lobe nearly covers the scutellum; prosternum com- 
pressed, the apex of the process wrinkled. LElytra with red epi- 
pleurze, but the limb very narrowly black. The markings are 
peculiar ; the basal one is like three irregularly shaped red spots
