218 THE CANADIAN ENTOMOLOGIST. 



nearly as in Perittia, but this insect has the tongue longer and scaled at 

 the base only ; as in Perittia, there are no ocelli, and no maxillary palpi, 

 the labial palpi (recurved in the living, porrected or drooping in the dead 

 insect) do not over-arch the vertex, but reach only about to the base of 

 the antennae, and taper gradually from the base to the apex, with the 

 articulations indistinct ; the antennae are simple, rather slender, and a 

 little more than half as long as the wings. The ornamentation, though 

 quite distinct from all other Glyphipterygidce, yet reminds one of Glyphip- 

 teryx by the smooth elevations of violaceous metallic spots, and of Dr. 

 Clemens' genus Hybroma, by the dark streak along the base of the costa. 

 Thus the head and its appendages ally this species to Perittia ; the wings 

 to jflLchmia, and less closely to Tenagma, while the secondary cell of the 

 fore wings and the ornamentation ally it more remotely to Glyphipteryx ; 

 the characters of the larva also ally it to Glyphipteryx, but the larvae of 

 the other genera mentioned above are unknown. 



Palpi, head and antennae like polished silver, the antennae annulate 

 with brown ; fore wings appearing to the unaided eye silver gray as far as 

 the ciliae, and the apical portion ochreous or golden, according to the 

 light, but under a lens the silver gray portion is resolved into a multitude 

 of narrow wavy lines, alternately white and black, which cross the entire 

 breadth of the wing ; the costal margin from the base to about the basal 

 fourth is velvety black, interrupted by two smooth metallic violaceous 

 streaks, nearly perpendicular to the margin and appearing to be raised a 

 little above the surface; and there is another on the extreme base of the 

 costa which is almost concealed by the patagia (or instead of this, we 

 may say there are three metallic violaceous spots, each widely margined 

 by velvety black, the posterior black margin of each confluent with the 

 anterior black margin of the succeeding one) ; a very little further back 

 and stili before the middle of the wing length, is another velvety black 

 spot (the fourth, counting the one on the base), containing another 

 metallic violaceous spot, and nearly opposite to this, but a little further 

 back, is a velvety black dorsal spot, containing also a metallic violaceous 

 spot, and further back on the costal margin, behind the middle, are two 

 spots of smooth violaceous metallic raised scales, not margined with 

 black, and opposite to the space between them, just within the dorsal 

 margin, near the end of the cell, is another one also unmargined, and on 

 the margin beneath it is a small white spot. In some lights all of the 

 metallic violaceous spots appear simply white, and in the golden ochreous
