292 RHYNCHOPHORA. 
2. Kustylus setipennis, sp.n. (Tab. XIII. figg. 21, 21a, ¢.) 
Elongate, narrow, rather convex, piceous; above densely clothed with brown scales, with cinereous or 
greenish-white scales intermixed, the lighter ones sometimes condensed into two faint vitte on the 
dise of the prothorax and a more or less distinct short oblique streak on the outer part of the elytra at 
about the middle, the scales on the flanks in part, and those on the under surface, usually cinereous or 
greenish-white; the elytra also set with numerous long, stiff, suberect, blunt setee down each of the 
dorsal interstices, the rest of the surface with short curled decumbent scattered sete, the tibiae pilose 
within. Head and rostrum canaliculate, the rostrum longer than broad, the scrobes subparallel as seen 
from above, the head flattened between the eyes and abruptly convex behind them, the eyes rounded 
and very prominent ; antennal scape very stout, reaching beyond the front margin of the prothorax, 
joint 2 of the funiculus longer than 1. Prothorax much longer than broad, subcylindrical, slightly 
rounded at the sides, sparsely punctate. Scutellum small. Elytra moderately elongate, punctate- 
striate, the alternate dorsal interstices sometimes becoming more or less costate posteriorly, the humeri 
not very prominent. Legs stout, anterior femora unarmed. 
Length 5-63, breadth 14-2 millim. (<.) 
Hab. Guatemata, Senahu and San Juan in Alta Vera Paz (Champion), Cacao near 
Trece Aguas (Schwarz and Barber, in U.S. Nat. Mus.). 
Five examples, apparently all males, varying in the colour of the scales, the Senahu 
specimen having the flanks of the prothorax and elytra in great part greenish-white. 
Near L. striatus, Boh., differing from it in the subparallel scrobes, the longer antennal 
scape, and the strongly setose elytra. 
3. Hustylus striatus. (Tab. XIII. fig. 22, 3.) 
Eustylus striatus, Boh. in Schénh. Gen. Cure. vil. 1, p. 42°. 
Length 54-7, breadth 13-23 millim. (¢ 9.) 
Hab. Mexico (Hegewisch, in coll. Sommer '). 
An elongate, narrow form, variegate or lineate above with a dense clothing of light 
and dark brown scales (the dark scales clustered into three narrow vitte on the 
prothorax and various interrupted lines or small confluent spots on the elytra), and 
also set with numerous, rather long, curved, adpressed, dark sete, the scales on the 
under surface greyish or opalescent ; the short deep scrobes converging posteriorly ; 
the eyes large and prominent; the antennal scape very stout and reaching the front 
of the prothorax ; the prothorax elongate ; the elytra very gradually narrowing from 
the base in ¢, broader, subparailel in their basal half, and more abruptly acuminate 
in 2, the alternate interstices costate; the anterior femora unarmed. This species is 
not represented in any of the extensive Mexican collections received by us, but there 
are six examples of it in the Sommer collection, now in the Oxford University Museum, 
the male figured having been kindly presented by Prof. Poulton. 
4, Kustylus quadrigibbus, sp.n. (Tab. XIII. figg. 23, 23, 3.) 
Moderately elongate, narrow (d ), broader (@ ), piceous or ferruginous ; densely clothed with coppery-brown 
scales, the prothorax with an indication of two faint paler stripes on the disc and the elytra each with 
un irregular, oblique, dirty white fascia just beyond the middle; the surface also set with scattered, 
curled, decumbent sete. Head and rostrum canaliculate, the rostrum longer than broad, widened
