98 THE ENTOMOLOGIST. 



prominent knot below the middle. The group which it represents 

 corresponds with Lederer's typical Zanclognatha. 



On the other hand, Dr. Moore, who worked out the synonymy 

 and fixed the types of genera for his work on the * Lepidoptera 

 of Ceylon,' gives H. harhalis, Clerck, as type of Herminia. From 

 the latter, I have been unable to distinguish Philometra* 



Lederer erroneously separated H. harhalis from Herminia, 

 and made it the type of his genus Pechipogon (Hiibner). Moore 

 quotes the latter in his synonymy of Herminia. 



Under Philometra, Prof. Smith quotes two species, P. goasalis 

 and P. eumelusalis. With regard to the first, I have a few 

 remarks to make, which I hope Prof. Smith will accept in the 

 friendly spirit in which they are intended. The following is the 

 species as rendered by Prof. Smith, and he must forgive me for 

 thinking that the synonymy was written down hurriedly. 



First of all he calls the species : — 



P. GOASALIS, Wlk. 



1859. Wlk., C. B. Mus., Het. xvi. 134, Epizeuxis. 

 I looked out this reference, and found no trace of Walker's 

 species ; but in vol. xix. p. 876, I found Epizeuxis gaosalis (sic). 



The next reference is : — 

 1859. Wlk., C. B. Mus., Het. xix. p. 876, Epizeuxis. metonalis,'SS\k. 



This also was not on the page indicated ; but in vol. xvi. 

 p. 236, I found Herminia metonalis, Wlk. 



The third reference is : — 



Wlk., C. B. Mus., Het. xvi. 236, Herminia. longilahris, Grt. 

 But on p. 236, Walker gives no reference to Grote's species. 



Now it is perfectly evident that the first reference (Het. xvi. 

 134) was not required at all ; the page quoted merely gives us an 

 enumeration, with diagnoses, of certain species of Epizeuxis 

 described by M. Guenee : take away this reference, shift the 

 others up, and all references become correct ; excepting that the 

 species is gaosalis not goasalis, and should be called metonalis. 

 The effect of this confusion in the synonymy is, that a mistake 

 has also been made in the note succeeding it, viz. : " Under 

 goasalis, Walker has also a specimen of Herminia petrealis, Grt., 

 which he did not recognize as distinct." 



Now anyone can satisfy himself, by looking up the correct 

 reference to Walker's Epizeuxis gaosalis, that only one example 

 ever existed under the name ; nor did I find any example which 

 could by any possibility be mistaken for a member of the group 

 in the drawer with it. But, under Herminia metonalis, there is a 

 somewhat aberrant example (the type), with an oblique dusky 



-'- Grote states that the antennae are shortly pectinate, without nodosity, 

 as one of the characters for Philometra, in which he is quite correct-
