SUPPLEMENT. 



The following supplementary pages contain descriptions of the new species received 

 during the progress of the present volume, together with indications of new localities 

 for species previously recorded and a few rectifications of synonymy, errors, and omis- 

 sions that have been detected since the foregoing parts were published. 



PSEUDOLUCANUS (p. 1 ; to precede the genus Cantharolethrus). 

 Pseudolucanus (Hope), Parry, Trans. Ent. Soc. Lond. 1870, p. 72. 



According to Major Parry this genus includes four described species, viz. one North- 

 American, one peculiar to the Mediterranean region, one Indian, and the following 

 from Northern Mexico : — 



1. Pseudolucanus mazama. 



Dorcus Mazama, Leconte, Proc. Acad. Phil. 1861, p. 345 ; Parry, Trans. Ent. Soc. Lond. 3rd ser.

 Pseudolucanus Mazama, Parry, Trans. Ent. Soc. Lond. 1870, p. 72. 



Hab. Mexico \ Santa Clara in Chihuahua (Edge). 



I am indebted to Mr. Flohr for calling my attention to this species, which was over- 

 looked in the former part of this work. It has since been captured in large numbers 

 by Herr Hoge. 



iESALUS (p. 2). 

 2 (a). <3Dsalus smithi. 



2E. neotropicali valde affinis et similis ; differt statura paullo majore coloreque subsenescenti-fusco et praeeipue 

 cantho oculari multo breviore et latiore ; supra nitidior, sparsius et discretius umbilicato-punctulatus, 

 setulis griseo-fuscis (haud nigro-fuscis) brevioribus et sparsioribus, elytrisque interstitiis planis. 



Long. 5 millim. 



Hab. Mexico, Chilpancingo in Guerrero (H. H. Smith). One example only. 



The much shorter and broader can thus of the eyes is the principal character which 

 distinguishes this species from M. neotropicalis, the length of the canthus being scarcely 

 one fourth the width of the eye and its ridge arcuated, whilst in JE. neotropicalis it is 

 about one half the length of the eye and linear, with a straight ridge. Compared with 

 a good series of JE. neotropicalis the surface is conspicuously more shining, due to the 

 more separated punctures and correspondingly sparser setse, which latter are also 

 shorter and lighter in colour.
