Pterophorus cineraceus, Fish, 

 Originally printed thus, but probably a mere printer's error for " cinerascens." 



Pterophorus luguhris, Fish. 



This should be carefully compared with the European rogenhoferi, Mn., and the 

 same remark must also apply to grisescens, Wlsm., which Dr. Jordan professed him- 

 self unable to separate from it [Ent. Mo. Mag., XVIII, 118 (1881)]. 



I reserve for the present any discussion of their possible identity, but would 

 add Arizona and Colorado to the localities for P. grisescens. 



Pterophorus inquinafus, Z. 

 = (Edematophorus mnhrosice, Mrt£. 



The neuration of inquinatus, Z., is figured, PL III, 5 — 6, and the genitalia, 

 PI. IV, 3 — 4, while the genitalia of amhrosice are figured, PI. VI, 14 — 17. These 

 two sets of figures certainly do not belong to the same species, and an unfortunate 

 error, either of synonymy or of name, has been made, which doubtless Dr. Fernald 

 can easily explain. 



Reference is omitted to Coquillett's description of the larva of (Edematophorus 

 inquinafus [Papilio, II, 61 — 2 (1882)], and to the West Indian records of Hayti 

 and St. Thomas ; Hedemann, Stett. Ent. Ztg., LVII, 9 (1896) ; Wlsm., Pr. Z. Soc. 

 Lond., 1897, 59, No. 7- Fernald confirms me in sinking ambrosiee as a synonym of 

 inquinatus. 



Stenopttilia pumilio, 7i. 



This species also occurs in Jamaica, St. Croix, St. Vincent, and Grenada. 



Stenoptilia (?) pumilio, Wlsm., Pr. Z. Soc. Lond., 1891, 495, 542 (1892). 

 MimcBseoptilus gilvidorsis (partim.), Hdm., Stett. Ent. Ztg., LVII, 8 — 9 (1896).

Having ventured on so many friendly criticisms, the more pleasant 

 duty remains to record the strong sense o£ obligation which all 

 students o£ the Pterophoridce must feel towards the author of this 

 most useful monograph. It represents the result, so far as it goes, of 

 an almost life-long study of this intricate subject, and Dr. Fernald 

 has been particularly fortunate in obtaining the types of both Fitch's 

 and Fish's species, thus giving to those who follow his descriptions 

 the utmost confidence in the conclusions at which he arrives. There 

 is little doubt that were he to publish all that he knows on the subject 

 he would be justified in adding further discoveries to the list of
