 The three last are new localities. 



In England, at Hereford, in 1890, on Ribes 

 sanguineum. (Morgan). It is also found in 

 Canada, being included in the check-lists of 

 inserts of the Dominion of Canada, compiled 

 by the Natural History Society of Toronto 

 and published in 1883. [Henshaw]. 



Chionasfis furfurus has been cited as 

 being found at New Mexico (Bull. No. 3, 

 N. M., Agr. Exp. Sta., Jan. 1891); but Prof. 

 Cockerell assures me that it has never been 

 found there. Walsh in Practical Entomolo- 

 gist, vol. I, p. 64, iS66, lists it as being very 

 common on willow in Illinois. And Riley 

 in American Naturalist, 1881, vol. 15, p. 4S7, 

 received them on raspberry from Oxford, 

 Miss. There is, perhaps, some doubt as to 



the identification of the scales on these food 

 plants. 



Chionaspis furfurus Fitch is a native 

 species, and was iirst observed by Harris in 

 1841, and was named by Fitch in 1856. It 

 has been commonly known as the scurfy 

 bark louse and Harris bark louse, and cited 

 by many authors as Aspidiotus furfurus, A, 

 cerasi^ Coccus harrisii, Asfidiotus harrisii 

 and Diaspis harrisii. 



Postscript. — Since the above was writ- 

 ten, I have received the following, kindly 

 furnished me by Prof. James Fletcher of 

 Ottawa, Canada. Chionaspis furfurus has 

 been received from Nova Scotia, New Bruns- 

 wick, and Prince Edwards Island, and 

 many have been imported on nursery stock. 

 It is not an uncommon species, but at the 

 same time by no means of frequent occur- 

 rence throughout Ontario west of this 

 point to tlie Niagara Peninsula and up to 

 Lake Huron and Georgia Bay. It has not 

 been received from British Columbia. 



DESCRIPTION OF THE LARVA OF CALOCAMPA CURVIMACULA. 



BY HARRI.SON G. DYAR, WASHINGTON D. C. 



I received these eggs through Dr. Ottolen- 

 gui under another name, but the determina- 

 tion was corrected by breeding. The mature 

 larva has been briefly described by Dr. Thax- 

 ter. The generic term Calocampa is utterly 

 inapplicable to this species, as the larvae are 

 plain, ordinary noctuids, far from "beauti- 

 ful." 



Egg. Hemispherical, rounded below, the 

 flat base small ; strongly vertically ribbed, 

 beaded, with ring-like micropyle. There are 

 about 40 ribs around the base, but they 

 diminish in number upward, not confluent 

 and are finely beaded. Diameter .8, height 

 .5 mm. 



Stage I. Head rounded, pale brown, not 

 shining; width .4 mm. Body slender, gait 



slightly looping, the abdominal feet of 

 joints 7 and 8 much smaller than the others, 

 especially on joint 7. Joint 12 a little en- 

 larged. Body smooth, light gray, food visi- 

 ble ; tubercles large, nearly black, circular, 

 iv equidistant between iii and v, vi not pres- 

 ent ; setae dark, distinct, but short. Cervical 

 shield brown; no anal plate. After feeding 

 the larvae became pale green. 



Stage II. Head pale greenish ; width .6 

 mm. Body long, slender, feet of joints 7 and 

 8 very small ; not shining sordid green with 

 narrow white dorsal, subdorsal and broader 

 stigmatal lines, none very distinct. Tuber- 

 cles minute; setae distinct, dark, normal. 

 Segments very indistinctly annulate. 



Stage III. Head whitish green, not shin-
