72 THE CANADIAN ENTOMOLOGIST. 



Tribe Tarac/iini. 

 The thorax is squamose, being covered with flattened scales. The 

 legs and wings are also covered with oppressed scales ; while the form is, 

 on the whole, like the preceding type. Whether more than the genus 

 Tar ache (Acontia) 2a-\d Chamyris belong here, I am doubtful — Tricho- 

 tarache having a resemblance to the Heliothians, to which Xanthodes and 

 Trileiica may also belong. The genus Tarache has its metropolis in 

 Africa. We have some twenty-two species, while Europe has but six. 

 The species bear a general resemblance to each other from the prevailing 

 white colour, to which terminimaculata offers a singular exception. Our 

 most beautiful species, with a resemblance to the exquisite moth Ciris 

 IVilsoni, is, perhaps, Ta?'ache lactipennis Harvey. 



Tribe Eustrotiiiii. 

 The moths are small, with broad squarish primaries, which have usually 

 somewhat of a tortriciform cut, rounded secondaries, the squamation on the 

 body thin, mixed scales and hair. The eyes are naked, antennae simple, 

 the form is frail. Boisduval calls these insects '■'■ Noctuophale7iidce." 

 The caterpillars are 12 or 14-foqted. The typical genus Eustrotia 

 ( Erastria) has nine European and thirteen American species. The 

 European genus Thalpochares, with twenty-six European species, is but 

 sparingly represented with us. I have been able only to study the neur- 

 ation of aetheria, which is an undoubted Thalpochares. In this group I 

 have found the neuration useful in separating the genera. From neur- 

 ational characters I have separated the American forms, related to the 

 European genus Agrophila, under Spragueia. I have also referred here, 

 under the generic name Euherrichia., certain American forms with silvery 

 marks, previously referred to Eriopus. The peculiar Californian genus 

 Annaphila, with fourteen species curiously resembling miniature Brephince, 

 I refer also here. Among interesting American genera are Exyra, which 

 is parasitic on Sarracenia, the pitcher plants ; Escaria, a western form, 

 and Azenia with large clypeal projection. This tribe, although represent- 

 ed by some of the principal European genera, offers many peculiar 

 American forms, such as 2ripudia^ Gyros and Fruva. The departure 

 from the European types is perceivable. Consult for the neuration of 

 Thalpochares and Eustrotia Grote, N. Am. Ent, I., p. 46-47. Also, 

 for the structure of Eroty/a, Spragueia, Fruva, Xanthoptera and Exyra,
