Ill 



Neopiiylax, gen. nov. 



Calcaria 1, 2, 4<. Ala? anticaD dense pubescentes, apicem versus 

 gradatim dilatatae, margine apicali sinuato ; cellula discoidali 

 elongata : posticae cellulis apicalibus 5 instructs?. Abdomen 

 infra apicem versus dentibus duobus instructum ( c? ). 

 Head. Antennae about the length of the wings, moderately short, the 

 basal joint longer than the head. Eyes large. Ocelli present. Max- 

 illary palpi with short and oval basal joint ; second joint long, 

 gradually thickened ; third joint rather shorter than the second, cy- 

 lindrical : labial palpi with two short and thick basal joints, and a 

 longer, slender, and cylindrical terminal joint. Thorax short. Ab- 

 domen slender : penultimate and antepenultimate segments each fur- 

 nished with a tooth beneath : appendices little prominent. Legs mo- 

 derately long; tibiae and tarsi with few spines: spurs 1, 2, 4; the 

 inner subapical spur on the posterior tibiae very small, scarcely more 

 than a tooth -like tubercle ; the other pairs subequal. 

 Anterior wings clothed with dense short pubescence, and with short 

 fringes ; narrow at the base, gradually widened to the apex ; apical 

 margin oblique, slightly emarginate in the middle of the margin of 

 the fourth apical cell, elevated at the point of termination of upper 

 branch of the fork of the ramus thyrifer, and afterwards gradually 

 emarginate to the anal angle, which is rounded ; discoidal cell very 

 long and narrow, closed ; apical cells long and narrow, the first, third, 

 and fifth acute, or subacute, at the base, and longer than the second and 

 fourth ; radius strongly bent before its termination. Posterior wings 

 broad, the fringes long at the anal angle ; subcosta and radius run- 

 ning very close together for more than half their length, then becom- 

 ing confluent, or nearly so, afterwards disuniting, the radius then 

 curved ; ramus subdiscoidalis simple ; hence there are only five apical 

 cells (three apical and two subapical, according to the nomenclature 

 of Kolenati); discoidal cell broad, closed (d 1 ). 

 A singular genus, which should probably be placed near Apa- 

 tania, with which it agrees in its spur-formula and densely pubes- 

 cent anterior wings. The shape of the anterior wings is peculiar, 

 and the neuration of the posterior wings very remarkable in the 

 small number of apical cells, in this respect unique in the family 

 Limnophilidaa. 



Neophylax concinnus, nov. sp. N. testaceus. Pedes nigro-spi- 

 nosi. Aiae anticae fulvae, fusco-pubescentes, punctis albidis obsoletis 

 irroratae ; margo dorsalis maculis tribus flavis ornatus ; cdiis apica- 

 libus fuscis, albido-interruptis ; posticae fumato-subhyalinae.
