102 THE CANADIAN ENTOMOLOGIST. 



the fore wing following the faint submarginal white Hne instead of pre- 

 ceding it as it does in both iincanaria and Califoruiaria, 

 Our species should stand as follows : 



(i) Plataea Californiaria, Herr.-Sch. 

 = personaria, Hy. Edw, 



(2) P. uncanaria, Guenee. 



(3) P. diva, Hulst. 



(4) P. trilinearia, Packard. 



= ? dulcearia, Grote. 



Californiaria seems to be widely distributed in the State, and to be 

 common in April and May. 



Uncanaria is not so common. My specimens were taken in Sonoma 

 County in May. 



Diva is rare in collections. The type was from the Argus Mountains 

 (Riley), and my own specimen was received from Mr. F. Grinnell, who 

 took it on the San Bernardino mountains, at an elevation of 8,500 feet. 



Trilinearia is the most abundant form. Dyar's list gives TexaS) 

 Colorado, Arizona and Nevada as localities, and I can add to these 

 California, Kansas, British Columbia and Alberta. 



Dulcearia^ Grote, is placed by Hulst as a synomyn of trilinearia, 

 and probably quite rightly. Grote, however, says that the two can readily 

 be distinguished, and I must say I have never seen a specimen quite 

 agreeing with Grote's diagnosis. Possibly Grote may have been misled 

 by the very faulty figure in Monograph. 



The Chora detnorsaria of Strecker, " which is placed in the genus 

 Plataea by Hulst, is said by Dr. Dyar to be based on a specimen of 

 Spodolepis substriataria. 



A NEW CANADIAN SPECIES OF COPIDOSOMA. 



BV L. O. HOWARD, WASHINGTON, D. C. 



The little Chalcidid parasites of Lepidopterous larvae belonging to 

 the genera Copidosoma, Litomastix and Ageniaspis, are of especial in- 

 terest at this time, on account of the extraordinary discoveries in the de- 

 velopment of these forms that have been made by Marchal and Silvestri. 

 Mr. H. H. Lyman some time ago rearing a number of specimens of one 

 of these insects from the larvae of Anacanipsis lupinella, Busck, taken on 

 a species of Lupinus at Toronto, sent the reared specimens to the Depart-
