A NEW ELACHISTID MOTH FROM MANITOBA.* - 



BY ARTHUR GIBSON, 



Chief Assistant Entomologist, Department of Agriculture, Ottawa. 



Among some micros collected at Aweme, Man., by Mr. 

 Norman Criddle, Field Officer of the Dominion Entomological 

 Service, are two specimens of a species of Heliodines, of the family 

 Elachistidae, which is undescribed. The specimens were reared by 

 Mr. Criddle from larvae found feeding on Oxybaphus nyctagineus, 

 a widely occurring representative of the Nyctaginxcece in Canada. 

 I therefore propose the name: 



Heliodines nyctaginella, sp. now 



Antennae dark metallic grayish-purple. Palpi pale yellow, 

 tipped with black. Face, head and thorax blackish, shining; 

 thorax with greenish reflections. Fore-wings bright golden-orange, 

 with nine metallic bluish-gray, more or less elongate, spots, six 

 costal and three dorsal, all edged with black basally. Base of 

 costa and margin of dorsum to first dorsal spot black. Space
