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 
coxse. 
Leptobunus spinulatus, sp. nov. 
Length ii mm., femur I, 5 mm., femur IT, 9 mm. Black, mandibles pale yel¬ 
lowish, patella, tibia, and basal half of tarsus, of palpus yellow brown, coxse 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; coxse with granules, and trochanters spinulate, rows of spin¬ 
ules on the femora, more irregular on patella and smaller on tibise; tibia II nearly 
smooth, with two false articulations, none in other tibise, none in anterior metatarsi; 
abdomen with transverse rows of minute, pale, pointed tubercles, rather few in a row.

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
