Specimens of the larvae of the Army Worm (Leucania unipuncta) 

 were received from Muscatine County with the information that they 

 were injuring crops in a considerable area in that county, but as they 

 were evidently full grown probably their injuries ceased almost im- 

 mediately afterward, so that I have no further information as to in- 

 juries from them or of their being present in any other localities in that 

 part of the State. 



The Clover-seed Caterpillar (Grapholitha interstinctana) was again 

 plentiful and caused a considerable loss in the clover crop. This 

 species feeds readily on the leaves or in the crown of the plant and so 

 does much injury aside from its destruction of the clover seed. 



A common Pyralid moth related to the species of Crambus, the 

 Xomophila noctuella, was extremely plentiful in grass land during early 

 October, swarms of them being seen in all pastures and meadows. In 

 a previous report I have called attention to this species as a probable 

 serious pest in grasses, with habits similar to those of Crambus, and 

 the observations this season on the numbers of the adults and their 

 habits confirm my opinion that they have larval habits similar to 

 Crambus and that they must cause a serious loss in pastures and 

 meadows. Work upon other species has precluded any effort to trace 

 the larval history the past season, and so far as I am aware nothing 

 has been recorded with regard to it. It seems to me well deserving of 

 investigation. The imagos of Crambus exsiceatus, a species Avhich has 

 heretofore been reported upon, with details of its life history, were 

 plentiful this season, but not in such numbers as in some former years. 

 Still they may be counted as among the very constant destructive 

 species. 



Edema albifrons was quite plentiful on Oak, and has been received 

 from other localities, and would seem to be more than ordinarily 

 destructive this season. 



The larvae of quite a number of Lepidoptera that are usually rather 

 scarce or inconspicuous were during autumn quite abundant. Among 

 these I may mention Papilio cresphontes, which, though usually very 

 rare here, was taken in considerable numbers upon Prickly Ash. 

 Mamestra picta, generally rare here (which may sound strange to ento. 

 mologists in some other localities), was fairly common, though not to be 

 counted a destructive species. Actias luna was quite common and 

 many specimens were brought in by students. Also Hyper chiria io, 

 very seldom seen in any great numbers, was found in considerable 

 numbers. Datana angusii. as usual, was abundant, and Grapta inter- 

 rogationis and Vanessa ajitiopawere, conspicuous in their attacks. The 

 common species, Papilio turnus and Papilio asterias, were more abun- 

 dant than usual, and in some cases did damage to their respective food- 

 plants. 



At the meeting of the Association of Economic Entomologists held 

 in August I reported some notes on the life histories of certain Jassi-
