Lab'ial palpi cuspidate, nearly concealed by hair, porrected, triarticu- 

 late? the basal joint very obscure, 2nd small, 3rd large, oval. Head 

 small. Ei/es small, globose, granulated. Thorax large in the males 

 alone. Abdomen sometimes short and truncated in the male, sabovate 

 in the female. Wings large and rounded, rarely small and lanceolate 

 in the female. Legs slender. Tibice anterior with a short slender 

 spine on the internal side, the others spurred only at their apex. Tarsi 

 5-jointed, basal joint the longest, penultimate the smallest. Claius 

 and 2ndvilU distinct. Larva with 6 pectoral, 8 abdominal, and 2 anal 

 feet, tuberculated,each tubercle producing a bundle of hairs." — Curtis, 

 Brit. Ent. V. 213.

" Faljn very hairy, triarticulate; the basal joint nearly half as long as the 

 second, somewhat clavate j the second elongate, clavate j the terminal 

 ovate, acute : maxillcB obsolete. Antennce short, acute, very strongly 

 bipectinated in the males, slightly in the females: head small, very 

 pilose : thorax rather short and downy : abdomen slender, and tufted 

 at the apex in the male, rather short and attenuated in the female, 

 with the apex acute and naked : luings deflexed, thickly clothed w'lth 

 scales: legs not very slender; /emom and tibicB fringed with hairs. 

 Larva elongate, attenuated posteriorly, with fascicles of hair on the 

 back and sides; those behind the head and on the penultimate seg- 

 ment longest, l^upa smooth, with tufts of hair on the segments, the 

 terminal one with an obtuse projection : changes in a loose folliculus." 

 "This genus differs from the foregoing {Hi/2}ogi/mna) hy having the basal 



joint of the palpi elongate, somewhat triangular and clavate, the terminal 



acute, and closely allied to the preceding ; the female has the abdomen 



moderately stout, and attenuated posteriorly, with the ovipositor exposed."

" Palpi hairy, short, triarticulate, the basal joint minute, second elongate, 

 subclavate, terminal ovate, obtuse : maxillce obsolete. Antennce short, 

 acute at the tip, very strongly bipectinated in the males, slightly in the 

 females : head minute, with a downy tuft : thorax and abdomen stout, 

 woolly, the latter very robust and obtuse in the female, and terminated 

 by 3 downy mass, rather attenuated, and furnished with a hairy tuft in 

 the male : wings deflexed, not very densely clothed with scales : legs 

 not very stout ; femora and tibia: slightly fringed with long hairs. 

 Larva elongate, cylindric, with short, rigid hairs on the back, and 

 elongate fascicles on the sides of tiie head, and at the tail : pupa 

 slightly hairy, the apex with a truncate projection : it changes in a 

 loose cocoon." — Steph. Illust. Brit. Ent. II. 65.
