2^94 [September, 



I have a specimen received some years ago from Mr. Fish, under the latter 

 name, •which is cei'tainly identical with suhocTiraceus. This name would therefore be 

 entitled to take precedence if (as I have no reason to doubt) Fish was rightly ac- 

 quainted with Chambers' species, but the name is incorrectly formed, and cannot be 

 emended to galactodactylus or to lacteipennis, as these names have already been 

 used. It would appear, therefore, that the name suhochraceus should be retained. 



JPterophorus sulphureodactylus, Pack. 

 Here, I venture to think, the protest against a mongrel name formed in defiance 

 of a well-acknowledged rule of zoological nomenclature founded on orthography 

 should be sustained. The proper correction to thiododactylus cannot be made, for 

 Hiibner published a theiodactyla, and therefore (Pter. Cal. and Or., p. 49), I sug- 

 gested the substitution of sulphureus. 



Pterophorus paleaceus, Z. 

 This species was recorded from Portorico by Moschler, Ab. Senck. Nat. Ges., 

 XY, 346, 354 (1890), and included in my West Indian lists, Pr. Z. Soc. Lond.,1891, 

 495, 542 (1892) : 1897, 60, No. 14. The synonymy == Leioptilus sericidactylus, 

 Mrtf., is undoubtedly correct, and was accidentally omitted from my papers. 



Pteo^opTiorus agrapTiodactylus, Wkr. 

 Fernald omits to mention the synonymy, = aspilodactylus, Wkr., under which 

 name the species was recorded from Jamaica by Butler, Pr. Z. Soc. Lond., 1878, 

 495, vide Wlsm., Pr. Z. Soc. Lond., 1897, 61, No. 17. 



Pteropliorus parvus, Wlsm. 

 I recorded this from Grenada, Pr. Z. Soc, Lond., 1897, 60, No. 10, and 

 the distribution of this, rather peculiar species may now be extended as follows ;— 

 Arizona (Morrison), Peru, Callao (J. J. Walker). Two specimens in the Zeller 

 collection (unnamed) were evidently collected by Petersen in Colombia. 



Pterophorus cretidactylus, Fitcli. 



Here, again, the author omits to adopt the suggested correction of a mongrel 

 name \_gypsodactylus, Fitch, Wlsm. (emend), Pt. Cal. and Or., 35]. In the 

 " Canadian Entomologist " [XXV, 96 (1893)] Dr. Fernald pointed out that occi- 

 dentalis, Wlsm., was a synonym of this species, and his description now published 

 tends to confirm this view, which cannot be well disputed since he has Fitch's types. 

 I am under a strong impression that up to the date 1885 (or thereabouts, if not much 

 later), he shared the view of Zeller and myself, that the species afterwards described 

 as eupatorii, Fern., was the true cretidactylus, Fitch. I have again carefully studied 

 the original description, and the correction should be accepted. 



In this genus there are several groups of recognised species, which run very 

 closely one with another, and where further study may reduce some of their number 

 to mere synonyms. These are respectively as follows : — 



Crogenlioferi, Mn. 



■s grisescens, Wlsm.
