168 RHYNCHOPHORA. 
serrate ; surface convex, punctate-striate, the strie rather deep and crenate, interstices nearly flat, with a 
single series of somewhat tuberculate rugs, finer towards apex, and bearing short fuscous-black bristles. 
Underside and legs piceous-black, the tarsi lighter. 
Hab. GuateMa.a, El Reposo (Champion). 
Twelve specimens were taken, of which the majority were immature. This species 
can be separated from P. setulosus and other closely allied forms by the fact that the 
elytral bristles appear black or deep fuscous, even in immature examples. To it must 
be referred for the present a single example from British Honduras (Blancaneauz). 
The specimen, a female, differs little except in length (1°7 millim.), being not more 
than half as large as normal specimens of P. subovatus; it is a little narrower, the 
front has no arcuate impression, the thoracic tubercles are nearly obsolete, and the 
elytral interstices less prominently wrinkled. These features are all consistent with 
depauperization. 
11. Phleotribus sodalis, sp. n. 
Ovalis, convexus, subnitidus, nigro-piceus, elytrorum disco pedibusque rufescentibus, breviter parce fusco- 
pilosus; prothorace transverso, antice subangustato, irregulariter rugose punctato, anterius tuberculato ; 
elytris crenato-striatis, interstitiis transverse rugosis et seriato-setosis, in declivitate spinose tuberculatis, 
margine apicali serrato. 
Long. 2°7 millim. 
Mas. Fronte impressa; prothorace anterius xqualiter tuberculato; interstitiis alternis in declivitate fortius 
tuberculatis. 
Fem. Prothoracis angulis anticis muricatis ; interstitiis equaliter tuberculatis. 
Oval, convex, moderately shining. Head black, vertex dull, shagreened and punctured, front ( ¢ ) subnitid, 
impressed, and with a short median linear sulcus and prominent lateral tubercles, convex (2) with an 
arcuate transverse impression; antennee piceous-red with the club infuscate, scape ( ¢) with a long pencil 
of fuscous hairs. Prothorax transverse, subconstricted towards apex, and not hemispherical, the apex 
more obtuse in the female, base obtuse; surface piceous, lighter towards middle of base, indistinctly 
elevated along middle, with scanty erect hairs, subcoriaceous, with shallow rugose punctures of different 
sizes, the front half with scattered asperities (¢), weaker or absent (2), with the anterior angles 
muricate. Elytra twice as long as the prothorax, with which they complete a uniform oval, the basal 
borders not strongly elevated nor crenate, the apical margin somewhat acute and serrate; surface 
piceous-brown, darker at sides and round scutellum, with crenate indistinctly punctured strie, interstices 
nearly fiat, with transverse elevated rugs replaced on the declivity by small spinous tubercles, rather 
more prominent on the first and alternate interstices in the male, the seriate bristles obscure brown. 
Underside black, pubescent. Legs piceous-red. 
Hab. GuatEMALA, Panajachel, Cerro Zunil (Champion). 
Three specimens, of which two are females, were taken at Cerro Zunil, and from 
these the description has been drawn up. ‘The example, a female, from Panajachel 
differs in some respects: it is black with the tarsi and antenne (except the club) alone 
reddish ; the prothorax is more strongly tuberculate in front near the middle line, and 
the punctuation of its basal half is stronger and less irregular; the basal margins of 
the elytra are more elevated and crenate, the interstitial ruge are stronger and the 
hairs more infuscate.
