Genus Diasemia Hbn. 

 Diasemia alaskalis, n. sp.

 thorax reddish-brown; abdomen brown, whitish towards end; legs whitish. 

 Primaries pale brownish with whitish scales along costa from base to reniform

 with brown; costal margin yellowish-brown. T.a. line brown, sinuous, indistinct 

 on costa. Orbicular oval, defined by brown, rilled with yellowish-brown. 

 Reniform rather large of an elongate-quadrate shape, slightly constricted 

 centrally and filled with yellowish-brown. T.p. line dark brown, slightly 

 dentate, almost straight from costa to vein 4 then incurved to below reniform 

 on vein 2 and then excurved to inner margin. Terminal line brown, widened 

 into conspicuous spots at ends of veins. Fringes pale brown, darker brown 

 centrally. Secondaries whitish, thinly spotted with brown scales; discal spot

 ancHhe costal margin, as also a brown subterminal line; fringes as on primaries.

Alar expanse, 22 mm. 



Type, a male, in the Canadian National collection from Collinson point, 

 Alaska, July 10, 1914 (F. Johansen). One paratype, bearing label " W. of 

 Konganevik (Camden bay), Alaska, beginning of July, 1914 (F. Johansen)." 

 The primaries of this specimen are more heavily dusted with brown than are 

 those of the type. 



Dr. Dyar kindly compared the specimen which I have made the type with 

 material in the United States National Museum and reported that it represented 

 an undescribed species of Diasemia. 



The type is figured on PL V, fig. 11. 



Genus Titanic Hbn. 

 Titanic species 1. 



Two specimens collected at Bernard harbour, Northwest Territories, one 

 August 4, 1915, the other in July, 1916 (F. Johansen), were submitted to Dr. 

 Dyar, who reported that they represented an undescribed species of the genus 

 Titanio close to alticolalis B. and McD. The specimens, however, are con- 

 siderably rubbed and for this reason I do not at present care to give the species 

 a definite name. 



Titanio species 2. 



A third specimen from cape Pullen, Wollaston Land, Victoria island, North- 

 west Territories, July 15, 1915 (D. Jenness), probably also belongs to the genus 

 Titanio and represents another undescribed species. It too, unfortunately, is in 

 poor condition.
