prothorax has a dark brown sinuous vitta along the outer edge and a paler line inside 
this at the base. 
11. Phace striatipennis, sp.n. (Tab. XXX. figg. 21, 21a, 9.) 
Oblong-ovate, black, the rostrum rufo-piceous, the antenne ferruginous ; densely clothed with pale brownish 
scales intermixed with very short, small, erect light and dark scales, these latter seriately arranged down 
each elytral interstice; the prothorax with a broad, transversely-subquadrate patch on the disc behind 
and a streak on each side of it, and the elytra with a common, angulate, anteriorly evanescent, submedian 
fascia, some indefinite markings between this and the base, a small spot at the apex of the fifth interstice, 
and an oblong patch on the suture at the tip, infuscate or black, the scutellum whitish; the vestiture of 
the under surface and legs pale, the legs annulate with brownish. Head and base of the rostrum densely, 
and the rest of the latter sparsely and very finely, punctate; antenne inserted at the middle of the 
rostrum, joint 2 of the funiculus a little shorter than 1. Prothorax transverse, narrowed and slightly 
constricted in front, feebly bisinuate at the base, the sides rounded anteriorly and almost parallel behind ; 
densely, finely punctate. Scutellum small. LElytra very little wider than the prothorax, and at the sides 
forming an almost continuous outline with it, slightly flattened on the disc, the humeri obtuse ; finely 
punctate-striate, the punctures oblong in shape, the interstices convex and densely punctulate. Beneath 
somewhat coarsely, closely punctate. Legs rather stout; femora feebly clavate, unarmed. 
Length 54, breadth 2,% millim. ( 9.) 
Hab. Guatemata, Rio Dulce, Yzabal (Sal/é). 
- One specimen. In this insect the elytra, which are very little wider than the 
prothorax, are subparallel at the base, and have sharply-defined striz, and an angulate, 
blackish submedian fascia, followed by a broad pallid subapical fascia; the outer row 
of punctures (the tenth) extends to near the apex. 
PEUCRON, gen. nov. 
Rostrum stout, curved, about as long as the prothorax; eyes laterally placed, large, separated by the width 
of the rostrum, almost covered in repose; antennee with the funiculus 7-jointed, the club ovate; prothorax 
transverse, arcuately dilated at the sides, deeply bisinuate at the base, the median lobe almost filling the 
scutellar cavity, the ocular lobes well-developed; scutellum very minute or invisible; elytra somewhat 
rounded at the sides, the base sinuate, the humeri effaced, the tenth row of punctures short ; mesosternum 
prominent, arcuato-emarginate; metasternum very short, the episterna moderately broad; ventral 
segment 2 as long as 3 and 4 united, the first suture arched; legs short ; femora moderately clavate, 
unidentate ; tibise carinate, rounded at the base externally ; tarsal claws simple; body subovate, squamose. 
Type, P. alboguttatus. 
The type of this genus is distributed in various collections under the MS. name of 
Acalles alboguttatus, Chevr. It may be briefly described as a Phace with the base 
of the prothorax deeply bisinuate and the elytral humeri effaced.

Acalles alboguttatus, Chevr. in litt. 
Subovate, opaque, black, the antenne and tarsi ferruginous ; somewhat thickly clothed with small brownish 
scales, the prothorax with a short median line at the base and two minute spots on the disc, and the
