402 Mr. A. G. Butler on Nocturnal Lepidoptera 



This extrciordiuarj form comes nearer to Tarudaoi Walker 

 til an to any other genus : it doubtless belongs to the group of 

 genera allied to Gryptolechia ; the singular development of 

 bristles from the median vein of the secondaries, in order to 

 hold down a long hair-pencil which proceeds from the mar- 

 ginal abdominal furrow, is one of the most singular contri- 

 vances which 1 ever observed in a Lepidopterous insect. 



40. Euperissus cristatus, sp. n. (No. 72). 



Primaries above pale shining bronze-brown, with a black 

 spot at tlie end of the cell, a grey dot near the middle of the 

 cell, one or two (very indistinct) near the base, and one about 

 the middle of the interno-median area : secondaries silvery 

 grey, with the cilia from the median vein and the pencil from 

 the abdominal fold bright ochreous ; marginal fringe pale 

 brown, spotted obscurely with grey at the base : head clay- 

 brown ; thorax silvery ; abdomen pale buif ; basal joint of 

 antennte blackish, remainder of antennae and palpi cream- 

 coloured. Under surface shining silvery, metallic ; legs and 

 base of venter pale buff. Expanse of wings 11^ lines. 



One specimen. Mountains near Honolulu. 



Stcebeehinus, gen. nov. (Fig. 2, palpus.) 



Urharce affine genus, Ypsolopho * simile, differt autem palpis maris 

 permagnis crassis, scopis terminalibus expansis, feminie palpis 

 simphcibus longulis porrectis ; anteunis crassis. 



The development of the male palpi in this genus is con- 

 siderably greater tiian in the little South-American genus to 

 which Walker has given the name of Urhara ; this organ 

 curves upwards far above the head in StceherhinuSj and is 

 broadly fringed at the back, so as to present the appearance 

 of a hearth-broom f. 



41. StoeherJiinus testaceus, sp. n. (No. 73). 



Primai'ies above pale testaceous ; six dark brown spots 

 arranged in pairs, two at the base, two just beyond the basal 

 third, the fifth (which is largest) just below the end of the 

 cell, and the sixth in an oblique line with it on the dorsal 

 margin ; two or three widely-separated brown costal spots 

 and an arched series close to the outer margin ; a slender 

 brown marginal line, and a paler line near the base of the 



* Y. verhascellus especially. 



t The development is quite different from that in Anaplwra, being 

 quite slender and only emitting divergent bristles from the back of the 

 last joint.
