or markings from my $ that I could discover, I refrain from 

 giving it that standing at present. The species is a beautiful 

 one, as will be seen, and its markings approach in style the 

 emargataria Gn. That species is larger, a brown or cafe au lait 

 color, slightly strigate, with prominent discal dots and quite 

 different in appearance. 



Kcnipii Hulst, the type of which is a 9 , seems to me an 

 extreme varietal form of alcoolaria Gn. It is a fresh specimen, 

 with the ground color paler, less strigate or mottled, with the 

 cross lines more sharply drawn ; otherwise the same. I would 

 list our species as follows : 



Scrinaria H-Sch. 



=subprivaria Walk. 



== Hoscularia Grote. 

 var. rosaria Grote. 

 Keutzingi Grote. 



—nigrescaria Hulst. 

 Altruaria Pears. 



=keutzingaria Pack. 



Fervidaria H-Sch. 



= excurvaria Mor. 

 Alcoolaria Gn. 



var. kempii Hulst. 

 Phlogosaria Gn. 

 Emargataria Gn. 



= arrogaria Hulst. 

 Purpuraria Pears. 

 Approximaria Dyar. 



The vitality and power of resistance of the sheep tick, Melophagus 

 ovinus Linn. Being interested in a woolpulling establishment, I have 

 had the opportunity of observing the terrible punishment inflicted 

 upon the sheep ticks, after the sheepskins are brought into the shop, 

 and how they come out whole and very much alive after said punish- 

 ment. The skins are brought in all day up to six o'clock P. M., and 

 are put into large cement vats with running water, in which the 

 skins are totally submerged; they remain in these vats over night, 

 and the following morning are run through a scrub machine, a machine 

 for cleaning the wool, with steel blades on a cylinder, revolving nine 

 hundred times per minute; these blades and the force of water make 

 the wool as white as the driven snow, taking out burs and dirt. The 

 skins are then put into a hydro-extractor revolving twelve hundred 

 times a minute, from which the skins come out very nearly dry; 

 they are then painted on the pelt side with a very strong solution of 

 sulphide of sodium, folded, wool out, and laid in piles twelve high ; 

 in this position they remain for at least twenty-four hours, when they 

 go to the pullers' beams, and it is here that the pullers have their 

 troubles, for unless they see the ticks first, the latter will get under their 

 clothing wherever there is a chance, and try to make up the time 

 lost in the two or three days' fast. They finally succumb, however. 

 after the wool is pulled and goes into the drying machine, where the 

 temperature is two hundred and fifty degrees Fahrenheit. — Frank
