INSECTA SAUNDERSIANA. 
Longit. (cap. infl.) If lin. = 4 millim. 
Latit. mecl. elytr. 1^ lin. = 2f g millim. 
Patria: Colombia. 
Nearly allied to Br. umbrinus (Pachym .), Kl., Sch., but differs in 
having the scutellum subquadrate, the elytra not callose near the apex, 
and the posterior thighs not crenulate beneath before the apical spines. 
About the width of Br. Pisi, but much shorter. 
Head oblong -subquadrate, transversely impressed behind the eyes, 
where it forms a sort of neck nearly as long as the forehead, which has in 
the middle a high ridge extending from the transverse impression to the base 
of the rostrum, where it is obsolete ; upper part of the vertex convex, 
densely punctate, covered with a dense longitudinally arranged ferruginous- 
brown pile; part between the eyes (front) coarsely and distantly punctate, 
with a slighter pile of the same colour, placed transversely. Eyes large, 
crescent-shaped, obliquely approaching towards the rostrum in front, 
coarsely reticulate, pitchy. Rostrum , with the labrum, nearly as long as 
the head when at rest, being at the base (mandibles included) as wide as 
the latter, somewhat narrowed towards the apex, which is subtruncate ; 
base slightly and widely bi-impressed; from the base to two-thirds of its 
length coarsely punctate, tomentose like the front; apical third part po¬ 
lished, shining, glabrous, extremely finely punctulate. Labrum transverse, 
slightly rounded at the apex, polished, shining, glabrous, having two trans¬ 
verse rows of distant and rather strong punctures, interrupted in the mid¬ 
dle. Mandibles strong, long, moderately incurved, pointed at the apex, 
which is ferruginous ; their upper part longitudinally angularly elevated 
along the middle, forming a carina or ridge running to the apex; external 
side coarsely punctate, dull tomentose; internal side (observable only when 
the maudibles are laterally open) concave, polished, shining, very finely 
punctulate ; black, apex rufescent. Maxillary palpi black; other parts of 
the mouth, with the labial palpi , light rufous; apex of the maxillae pale 
yellow. Antennae moderately thick and long, peaching to the base of the 
thorax ; four basal joints together subcylindric; 1st the longest and thick¬ 
est; 2nd the shortest; 3rd and 4th subequal; 5th to 9th gradually more 
transverse, but subequal in length, not longer than the two preceding; 5th 
to 7th triangular, scarcely wider than long, especially the 5th; 8th and 9th 
half as wide again, nearly cup-shaped, as well as the 10th, which is nar¬ 
rower, shorter, and also transverse; terminal narrower than the 10th,
