female, much longer in the male ; basal joint strongly clavate ; 
dark brown, bases of the joints, from the fourth, grey. Thorax 
bituberculate on each side the central ridge, dingy tawny brown. 
Elytra elongated, gradually and slightly tapering from base to 
apex ; shoulders conical, base on each obtusely raised, finely 
punctured, colour uniform brownish tawny. Body beneath 
tawny brown ; abdomen black down the middle. Legs simple, 
icarcely dilated in the male ; black, thinly clothed

10. Hypselomus ligmcoloVy n. sp. 
H. subcylindricus, brunneus ; thorace et pectore vittis lateralibus 
obliquis, elytris sutura vittisque lateralibus abbreviatis curvatis, 
nigris pallide marginatis ; elytris compressis, sparsim punctatis, 
humeris paulo productis baud tuberculatis. Long. lin. 2 • 
Head tawny, spotted with dark brown. Antennae as long as 
the body ( $ ), moderately stout, brown, unicolorous. Thorax 
unarmed and free from tubercles, surface smooth, brown ; sides 
each with two oblique, blackish vittae, the upper one margined 
with dull ochreous ; there is also a short dusky central line near 
the middle of the hind margin. Scutellum blackish in the 
middle. Elytra nearly cylindrical, sides compressed, shoulders 
produced each into a slightly elevated ridge not surmounted by 
a tubercle; surface sparingly and finely punctured, brown, su- 
ture and several curved streaks on each side blackish, the lateral 
streaks margined on the upper sides with pallid brown. Body 
beneath brown ; breast with oblique stripes, dull ochreous and

Ega. This species is much more elongate and narrow than 
the typical forms of the genus ; it consorts, however, much better 
with the Hypselomi than with Hesycha or Oncideres (which com- 
prehend elongated forms), having antennse approximated on the 
forehead instead of widely separated at their bases. It seems to 
be nearly allied to Hypselomus egens, Erichson (Consp. Col. Peru, 
p. 148). 
11. Hypselomus obscurellusy n. sp.

trigonis, humeris conico-elevatis, obtusis. Long. 5| lin. S *
