110 MR. E. M'LACHLAN ON NEW TOBMS, ETC., 



should be placed next thereto. I have already (Stettiner ento- 

 mologische Zeitung, 1867, p. 54) separated certain forms with the 

 same number of spurs into a distinct genus under the term Pota- 

 moiites ; but these, in the narrower form, and pouched hind wings 

 of the male, come near Drusus. Platyphylax is really so near 

 Stenophylax that, without examining the spurs, the species might 

 pardonably be supposed to pertain to the latter. 



In JPlatyphjlax should be placed the European E. Frauenfeldii, 

 Brauer and JiJ. Xolenatii, Ko\. (=FrmtenfelduS'^), the North- 

 American JS. subfasciata, Say, E. desir/nata, Walker, and JE. lepida, 

 Hagen, and the Chinese species described below as P. lanuginosus. 



JE. irrorata, P. (^ = inter cisa, "Walk., Hag.), and E. prceterita, 

 Walk., probably form another genus. E. areolata, Walk., is 

 probably a true Enceeyla ; but it is desirable to see the female. 



Platyphylax lanuginosus, nov. sp. P. fuscus, abdomine ochraceo. 

 AntenriEe palpique fusco-nigri. Pedes flavi, tibiis tarsisque fusco- 

 nigris. Altae anticae latae, testaeeo-fuliginosaj, dense et breviter te- 

 staceo-hirsutse j venae pilis erectis fuscis fimbriatae : posticse fuliginoso- 

 subhyalinae, margine costali apicem versus flavido ( $ ). 



Long. Corp. 7 lin. ( = 15 mill.); exp. alar. 18 lin. (=37 mill.). 



Hab. Shanghai [in Mus. auct.). 



Head fuscous above, posterior margin and a small tubercle on each side 

 close to the eyes testaceous ; ocelli white ; ontennai blackisli, the 

 basal joint with blackish hairs, a few testaceous ones being intermin- 

 gled ; face ocbraceous j palpi blackish. Thorax fuscous above, ochra- 

 ceous beneath ; posterior half of metanotum yellowish. Legs: coxa;, 

 trochanters, and femora testaceous ; tibiae and tarsi fuscous, armed with 

 numerous short blackish spines. Abdomen ochraceous ; at the apex 

 are two short and obtuse appendices (my individual carries at the ex- 

 tremity of its abdomen a dried mass of gelatinous matter, such as en- 

 velopes the eggs). 



Anterior wings broad, the apical margin oblique, somewhat sinuate, and 

 narrowly darker ; the colour is smoky with a testaceous tinge ; and 

 there is a uniformly dense, almost woolly clothing of short procum- 

 bent testaceous hairs, intermingled with which are short, erect, blackish 

 hairs; and on the veins, especially on the cubitus, are longer, erect, 

 blackish hairs ; a wliite dot at the thyridium, and another at the ar- 

 culus ; veins pale fuscous ; first to fourth apical cells all more or less 

 truncate at the base, fifth acute, scarcely reaching the anastomosis, 

 furnished with a short footstalk j a black horny dot at the base of the 

 third apical cell. Posterior wings smoky subhyaline ; veins blackish- 

 fuscous ; apical portion of costal margin, and the subcosta and radius 

 at that portion yellowish. 



I have one female, from Shanghai, taken by Mr. W. B. Pryer.
