whitish on front and sides, and narrowly behind ; abdomen black, a whitish stripe on 

 the side of basal half and two or three of the segments behind are narrowly white 

 on the side of the apical margin ; coxae and venter almost black, four elongate whit- 

 ish spots just behind hind coxae, the basal one much the largest; trochanters black, 

 legs brown, pale on middle of femora, darker on patellae. Eye-tubercle moderately 

 prominent, faintly roughened above ; patella of palpus with a distinct projection at 

 inner end about as long as width of joint, tibia scarcely longer than patella, last joint 

 slightly curved, fully as long as tibia plus patella ; basal part of abdomen finely rug- 

 ulose, also the apical portion of the apical segments ; legs faintly roughened. 



Readily distinguished by the white front and white spots behind 

 coxae. 



Leptobunus spinulatus, sp. nov. 



Length n mm., femur I, 5 mm., femur II, 9 mm. Black, mandibles pale yel- 

 lowish, patella, tibia, and basal half of tarsus, of palpus yellow brown, coxae dark 

 yellow brown, extreme base of femora whitish, tarsi brownish. Eye-tutercle low, 

 with a few spinules above, a group of numerous spinules on front border, all small ; 

 palpi with short stiff hair, tibia much longer than patella, tarsus longer than both to- 

 gether, nearly straight; coxae with granules, and trochanters spinulate, rows of spin- 

 ules on the femora, more irregular on patella and smaller on tibiae ; tibia II nearly 

 smooth, with two false articulations, none in other tibiae, none in anterior metatarsi ; 

 abdomen with transverse rows of minute, pale, pointed tubercles, rather few in a row. 



Related to L. gratide, but much more spinulate. 



LIFE-HISTORY OF FERALIA JOCOSA. 



By Otto Seifert. 



This pretty species may be found in the vicinity of New York from 

 the last days of March to the end of April, wherever hemlock trees 

 (Tsuga Canadensis) grow in any number. The moths emerge from 

 their pupae about noon and ascend the hemlock trunks to develop their 

 wings. Sometimes, on very cold days, they remain resting near the 

 ground, as if paralyzed by the severity of the weather. When dis- 

 turbed, they seem indifferent at first, but later suddenly dart off, usually 

 to the higher branches of the trees. They are easily found, as their 

 bright colors contrast with the dark bark, especially after rain ; but 

 they are never abundant and seem to prefer spending their lives high up 

 amongst the foliage of the trees, so much resembling their own colors. 

 I have never been able to find a pair in copulation, though I have often 

 observed males and females on the same trunk. When taken home and
