Ariz., July 25, 1905 (Schaeffer). Another specimen is in the 

 Dury Collection from the Santa Rita Mts., Ariz. July 1915. 

 Three nearly similar specimens, but having a black venter, are 

 from uncertain Mexican sources. 



22. Chirida extensa Boh. I am indebted to Mr. Schaeffer 

 for the identification of this species which had been confused 

 among the pale specimens of C. guttata. Five specimens from 

 Brownsville, Tex. are in the National Collection, three of which 

 were taken June 9, 1895 by Mr. Schwarz, the other two having 

 been received from Schaeffer. 



23. Psalidonota leprosa (Boh.) or marmorata Champ. Seven 

 specimens from Brownsville, and one from the Guadalupe River, 

 Texas (Townsend, Wickham, Dury, Schaeffer and Mitchell, 

 collectors) are smaller than our more tropical specimens of 

 leprosa but. do not quite agree with marmorata. 



24. Deloyala clavata (Fabr). As above stated this species is 

 hereby chosen as the type of Chevrolat's long neglected genus, 

 and this combination was used in the Melsheimer catalogue 1853, 

 and by Riley 1870 and others, who allude to the species as an 

 enemy of the white potato. Pierce has found the species in Texas, 

 breeding on Physalis cornuta and Knab informs me that larvae 

 and adults occur on both white potatoes and bitter-sweet (Sola- 

 num dulcamara) in Massachusetts. Dr. Chittenden has a speci- 

 men labelled "on Solatium nigrum, Glen Echo, Md." Speci- 

 mens from Texas, New Mexico and Arizona are larger, paler and 

 less tuberculate posteriorly but are not regarded as specifically 

 distinct. They are believed to represent intergrades between 

 our eastern form and the Central American testudinaria, but I 

 am dissatisfied as to the strict application of Fabricius' name. 



25. Metriona bicolor (Fabr.) This, familiar to most of us 

 under the name Coptocycla aurichalcea, is apparently a composite 

 of ill-expressed local forms distributed throughout the United 

 States. Champion 1894 (Biol. Cent.-Amer. Coleop., vol. 6, pi. 

 2, p. 212) applies this name to a smaller and quite distinct form, 

 varieties of which he admits merge with a series of varietal forms 

 which he treats under the name trisignata and it seems certain to 

 the writer that in Texas, these latter merge with the series of 

 forms we have known as bicolor Fabr., aurichalcea Fabr., auri- 

 splendens Mann, and marylandica Hbst. with which Champion 

 thinks bis-tripunctata Hbst. may not be strictly synonymous. 

 Until their status can be better determined, further nomrnrlu- 

 torial changes would be unwise. The localities for this ubi- 

 quitous species are not indicated on the appended maps. Riley 

 1870 (2nd Ann. Rep. Nox. Ins. Mo., p. 62, figs. 33 and 34) cites 

 sweet-potato, morning-glory and bittersweet as hosts, but adults 

 are found evidently at home on a large number of plants, and
