[Oct., '14 



large part of the dorsum of 2, a transverse basal ring on 2)'7> sides of 

 8, much of 9 and 10. especially on the dorsum. 



Legs yellowish, articulations and tarsi blackish. 



The colors immediately after death of T. inopinata male, also taken 

 December 2, 1909, agreed with those noted above for pellucida, in- 

 cluding the pale colors of frons and nasus, but there was very little 

 pruinosity except on the ventral surface of the thorax and on the 

 posterior abdominal segments. The dark band on the wings varies 

 somewhat in width; its proximal edge is at the nodus, its distal edge 

 at the costa is from 16 to 20 mm. distad on the front wings, from 21 

 to 25 mm. distad on the hind pair. The male of May i, however, has 

 the proximal edge of this band 6 mm. beyond the nodus and the distal 

 edge at 21 and 26 mm. from the nodus on front and hind wings re- 

 spectively; the costal and radial spaces between nodus and the prox- 

 imal edge of the band are more or less brown. 



The colors of the body of Thaumatoneura females (dry, I have no 

 notes on living colors) are as in inopinata males. In none of them 

 is a distinct pale band on frons and nasus present, such as can be seen 

 plainly on the dried pellucida males; Nos. 2, 5, 6, 8, 10, 11 and 12, of 

 the table on page 343, show traces of pale color on these parts. The 

 markings at the tips of the wings are shown in PI. XIV, Figs. 2, 4, and 

 the dimensions of this brown area are given in the table just quoted. 

 Dorsum of abdominal segment 10 with a median longitudinal carina; 

 hind margin a little excised ; appendages subequal to 10 in length, 

 straight or nearly so, a little compressed, tai»ering to an acute apex, 

 black. Ovipositor proper (gonapophyses of 8 + median gonapophyses 

 of 9) reaching caudad not as far as the level of the hind end of 10, 

 each lateral half having ten to twelve obliquely transverse ridges on 

 its external (ectal) surface before the apex. Genital valves (lateral 

 gonapophyses of 9) reaching caudad beyond the level of the hind end 

 of ID, ventral edge of each in its caudal half hairy and denticulated, 

 hind end emarginated, valvular process attached at the deepest point 

 of the concavity and directed caudad and ventrad. 



The variation in the number of antenodals is as follows, the num- 

 bers giving percentages of wings :
