124 ME. E. m'lachlak on new foems, etc., 



iongis extus instructae. Antennae alls pauUo longiores, intus 

 Bubserratae. Palpi maxillarese longati ; articulo 1° brevi, 2° 

 et 3° elongatis, 4° et 5° brevioribus. Alae anticae amplae, 

 elongato-triangulares : pube brevi dense vestitae ; margine 

 apicali obliquo ; venis d $ asqualibus ; cellula discoidali oc- 

 clusa, elongata, angustata ; cellulis apicalibus novem angu- 

 statis, quarum I'' ad basin cellulae discoidalis fere extensa: 

 posticae breves, lata?; radio cum sectore primo ad apicem 

 conjuneto ( d* $ ). 



Head. Antennae stout, tapering to the apex, rather longer than the 

 wings 5 the basal joint short, subglobose ; third and succeeding joints 

 long (the third longer than the others) j each, at its apex internally, 

 carries one or two short spines or bristles, causing the autennse to 

 appear somewhat serrated, but these are absent in the extreme 

 apical portion. Eyes small. Maxillary palpi long, stout, hairy : 

 basal joint short ; second very long ; third slightly shorter than the 

 second, and thinner; fourth and fifth each about one-third shorter 

 than the third. Labial palpi small : basal joint very short ; second 

 long, third still longer than the second. Prothorax very small ; on 

 each side beneath is a semicircular lobe. Mesothorax oval, elongate. 

 Metathorax cordate. J 5c?ome« short, moderately stout; d superior 

 and inferior appendices present ; penis (or upper penis-cover ?) long, 

 triangular ; 5 , apex of abdomen oblique, forming a shallow cavity 

 beneath. Legs : anterior pair short ; intermediate and posterior very 

 long; posterior tibiaj of the c5' fringed externally with very long 

 silky hairs ; tarsal joints long ; in the J the first two joints have, ex- 

 ternally, long bristle-like hairs, which, becoming agglutinated, have 

 the appearance of long spines. Spurs: c?, 2,4,2, the pairs sub- 

 equal, those on the anterior tibia; shorter ; $ , 2, 4, 4. 



Wings. Anterior wings ample, elongately triangular, the apical mar- 

 gin oblique ; densely clothed with short pubescence ; fringes very 

 short : subcosta and radius regular, straight, connected towards the 

 apex by a transverse veinlet ; discoidal cell very long and narrow, 

 closed ; median cell longer than the discoidal, and broader ; cellula 

 thyridii commencing near the base and extending to the middle of 

 the median cell ; nine apical cellules, all of which are long, the first 

 extending to two-thirds the length of the discoidal cell, first, 

 third, fifth, seventh, and ninth acute at the base, second, fourth, 

 sixth, and eighth truncate. Posterior wings short and broad, the 

 costal margin rounded up to near the apex, the apical portion being 

 slightly excised ; apex obtuse ; radius Ijecoming confluent with the 

 fir.st apical sector before the apex ; neuration otherwise much as in 

 the anterior wings, allowing for the usual diff'erences ; the discoidal 

 cell is perhaps open in these wings (the possible position of a trans-
