30 SOME INSECTS INJURIOUS TO TRUCK CROPS. 



tained, but it was al)out the 21st of October, which woukl <>-ive a 

 period for the pupa of ten months, as the moths of this lot began 

 issuing August 21." 



One individual transformed to pupa October IT and the imago 

 issued August i>4 of the followmg year. 



October 15, 1898, the larva was brought to the writer by Mr. P. H. 

 Dorsett, from his greenhouse at Garrett Park, ^Id.. where the species 

 was feeding on the foliage of violet. The same year, November 3, 

 this larva was found rather abundantly by Doctor Howard in tobacco 

 fields in southern Virginia, near the North Carolina border line, upon 

 the leaves, which in some cases were badly ragged.^ The first moths 

 issued in July. 



During 1000 and 1001 correspondence Avas had in regard to this 

 caterpillar with Mr. H. Walter McWilliams, Griffin, Ga., wdio sent 

 specimens, as also larviv of the so-called cotton cutworm {Prodenia 

 ovn'dhogaUi Guen.), with which the insect was associated in both 

 years. The caterpillars were noticed there in greatest numl^ers during 

 NoA^ember, and both species were reported as destroying a number of 

 garden crops, among which were cabbage, coUards, turnip, ruta-baga, 

 rape, peas and related plants, as also some other vegetables. Mature 

 larva? were seen as late as the last week of November. 



Among other office records are two Avhich also have a bearing on 

 the biology of this species. One of these was made by ^Nlr. Theo. 

 Pergande, who found the larva^ in the District of Columbia feeding 

 on blackberry and on flowers of a goldenrod {Solid ago sp.). The 

 other is a short note by Mr. F. M. Webster upon the rearing of the 

 moth in spring from the ;eed pods of milkweed {Asdepias inrar- 

 nafa), near Lafayette, lud. " The larva appeared to subsist upon the 

 seeds, the pods being attached unopened to the wrecked plant." '' 



October 21 the larva was found at Washington, D. C. We have no 

 further records in regard to the hal)its of this species other than the 

 capture of moths in the District of Columbia July 25, August 22 and 

 25, and Septeml)er 2, and there are sijecimens also in the IT. S. 

 National ^Museum from Lewis County, N. Y., July 4, collected by 

 O. Meske, and others from New Jersey without definite locality. The 

 species is also said, to occur at Portland, Oregon. It is interesting to 

 note that among these specimens are inflated larvae and mounted 

 heads labeled " pretty cutworm," which might be termed a m-anu- 



« The i-earing ,i;ir was kept undev somewliat uiinatiu-nl conditions, at times 

 too warm and dry. but tlie effect of one condition mi,i;lit have been eounteracted 

 by another, and the date of issuance of the adults was not far from that which 

 would be assumed in nature — more likely earlier than otherwise.
