147. Pachyarches amphitritalis. 



Margarodes amphitritalis, Giienee, Delt. et Pyr., p. 307. 

 Pachyarches amphitritalis, S. & C, No. 4209. 



I never have seen the male of this apparently rare 

 but widespread species. According to Lederer, it belongs 

 to Pachyarches.

148. Margaronia fallacialis, nov. spec. 



A male of 32 mm. expanse. 



This species has very much the appearance of Pachyarches 

 psittacalis, but the antennae are normally formed, without a tooth- 

 like projection of the basal article or cm-ve at the base of the 

 hamper (see Lederer, Wien. Ent. Mon., vii., pi. 5, f. 7 (not fig. 6)), 

 and there is no fold at the under side of the costa of fore wings ; so 

 the species belongs to Margaronia {Margarodes, Lederer). Palpi 

 porrected, rostriform, bicolorous, white and brown. Antennae 

 green, minutely ciliated. Head, upper side of thorax, abdomen, 

 and wings bright green, as in psittacalis and Enchocnemidia 

 squamopedalis, the edge of costa of fore wings brownish, the dots 

 on the disco-ceUular hardly visible ; no marginal dots or other 

 markings. Fringes dark grey, shining; anal tuft black. Under 

 side of wings pale glaucous green, greyish towards the hind mar- 

 gins, as in psittacalis, but the costa of fore wings nearly con- 

 colorous, only very slightly greyish ; base of wings and body paler 

 and more bluish, again as in psittacalis ; middle and hind coxae 

 and tibiffi pale bluish green ; fore coxae mixed with ochreous, the 

 tibiae with a black spot ; all tarsi greyish white. 



As the name Margarodes is preoccupied in the 

 Hemiptera, I accept, following Walker and Moore, the 

 name Margarotiia of Hiibner's ' Verzeichniss'; but it is 

 my opinion that in other cases the so-called generic 

 names of that much antidated Catalogue never can 

 take priority over those of serious works. Hiibner's 

 ' Verzeichniss ' is, as Zeller very justly observes, a mere 

 name-store (Namen-magasin), without scientific value.
