The Walnut-Caterpillar {Dutaud anijHuii). — This cati-rpillar is frt'tiueutly very in- 

 juriou.s to small waluut trees aud often defoliates larfje ones that are situated away 

 from natural timber, but does not seom to bother the trees growing wild in natural 

 forests or along creek banks. On August 10, 1889, the writer observed at the foot of 

 some waluut trees bunches of these worms congregated, fully as large as a peck 

 measure. 



Yellow-necked Apple-tret* Caterpillar {Datana miniHtra). — Tliis caterpillar does 

 great damage to young apple trees, and also at times to larger ones. It has been 

 observed to completely defoliate trees three years from the nursery. It has not 

 made its appearance this season at this date. 



Fall Web-worm (Hifphantna ciinea, Drury). — Present in ([uitt; numerous colonies 

 some seasons, but seems to favor dry seasons ; does uot do as much damage as the 

 preceding. 



Corn Ear-worm or Boll Worm. — This was very numerous last year; hardly a jjer. 

 fect ear of corn could be found, and the excrement of the worm was so thick that, in 

 husking, large quantities accumulated among the corn in wagons and crib; it does 

 great damage from the fact that it makes it very hard to get perfect corn for seed. 



Codling Moth. — Very numerous ; nearly half of the apple crop was infested by this 

 moth; such apples as Ben Davis, Jonathan, etc., were more affected than such as 

 Wine-sap, Romanite, and apples of like quality. It has already made its appearance 

 in green Ben Davis apples on the writer's premises, its effects being easily seen by 

 the apples falling to the ground. 



Among other insects I may mention will be found the Plum Curculio, not very 

 numerous ; the white scale which was on willow and cottonwood trees at the writer's 

 premises for three years past has not made any appearance so far this season. — [Wil- 

 liam N. Hunter, Nebraska, July 23, 1891. 



Second letter. — The Corn Root-worm {Diahrotica longieornin). July 31: The 

 effects of this worm are commencing to make themselves shown after heavy rain 

 (that is, what was planted to corn last year and again this year). Last year they 

 were not present, at least I did not see or hear of any, but possibly the lack of rainfall 

 to soften the ground may have had the effect of leaving the corn standing instead of 

 its blowing down. August 17 : Its effects were more plain to be seen after the heavy 

 rain of the 14th and 15th; the mature beetles are plentifully present (August 22); 

 noticed complaints in local papers from the western end of the county that this 

 worm has been doing great damage. Since heavy rains accompanied by Avind its 

 effects have been already shown. September 15 : The mature insects are very niimer- 

 ous. I noticed them feeding extensively upon the flowers of the wild sunflower 

 growing alongside of the cornfields. They seem to favor this weed above all other 

 vegetation except corn. 



The Apple-tree Tent-caterpillar and the Codling Moth are fully up to the average 

 years. The former is much worse than for a number of years past. 



The Green-striped Maple Worm made its first appearance in this vicinity Septem- 

 ber 10, and in comparatively few numbers. 



Chinch Bug {Blisms leucopterus). I noticed the first appearance of this bug in 

 small numbers on August 5; the i)iuk larvie of the second age were most abundant. 

 Also noticed some of the short-winged variety at a later date, though it has uot 

 done any damage to crops worth mentioning. 



August 2. I noticed the first appearance of the Walnut Caterpillar {Datana angimi) 

 on some large walnut trees, but not in very extensive numbers. September 15. This 

 worm has proved very numerous and quite destructive to the foliage. — [William N. 

 Hunter, Nebraska, September 15, 1891. 



Pall Web-worm Parasites in Indian Territory. 



Since reading your article on the parasites of Hyphantria cunea, in Bulletin No. 10, 

 I have reared several species. I inclose for identification a few of these bred species, 

 both primary and secondary. No. 1 I take to be Meteorus hyphantriai and cocoons.
