Megalomus falcatus Blanchard, Historia Fisica y Politica de Chile, In- 

 sectos, p. 125, pi. I, fig. 8, 1849. 



This very interesting species, originally described on specimens from 

 Calbuco, Chile, is present amongst the material by two male specimens from 

 Masatierra, Juan Fernandez, December (Backstrom leg.). 



The two specimens agree in every respect with the short and insufficient 

 description and with the rather good figure, given by BLANCHARD. 



Head pale yellowish brown; labrum and clypeus smooth and shining; 

 face and vertex dispersedly and deeply punctuate. Basal part of apical joint 

 of maxillary and labial palpi blackish. Antennae 54-jointed, half as long as 

 the forewing, brown and with pale annulations; basal joint stout, subconical and 

 pale; second joint half as long as basal joint, much narrower and with a dark 

 ring at apex; third and following joints broader than long; the apical joints 

 as long as broad. Prothorax pale yellowish brown, more than twice as broad 

 as long, with front and hind margin parallel to each other. Me.so- and meta-

thorax pale yellowish brown. Pro- and metathorax with short yellowish hairs. 

 Abdomen pale brown and with pale hairs. Legs pale, tip of tibiae and tarsi 

 a little darker. Basal tarsal joint as long as second and third united; second 

 joint a little longer than third; third and fourth of the same length; fifth as 

 long as third and fourth united. Forewing rather long and broad, strongly 

 falcate at apex. Membrane with yellowish tinge. Venation pale yellowish 

 brown, very dense and irregular in the basal third part, more open and regular 

 in the two apical third parts. Costal area very broad at base, and with a 

 recurrent vein, circumscribing a long, narrow, rectangular space. Sc. and R 

 united at their tip. Subcostal area with many crossveins in basal half part. 

 Six radial sectors; the sixth with three branches. Along the margins several 

 small blackish spots; a rather large spot is found where R and Sc unite. In 

 the basal part and near the hind margin three or four spots, and in basal part 

 of costal area and on the disc several smaller or larger spots are present. 

 Almost in the centre of the wing a rather large brownish opaque circular spot 

 is found. The hindwings smaller than forewings and slightly falcate at tip. 

 Membrane hyaline with a faint yellowish tinge along the margin. Venation
