tree growing on the bank of the stream. It was found late in 

 the afternoon, and further search then and during a subsequent 

 visit failed to reveal more specimens. The species is appar- 

 ently unnamed but I do not care to name it from such scanty 

 material. A brief description of the single female follows : 



Abdomen 30, hind wing 25.5. Labrum, nasus and frons in 

 front rich dark brown ; rhinarium and a small spot on the lat- 

 eral margin of the nasus gray ; frons above in front greenish 

 yellow, the posterior half and the vertex brown, and the occiput 

 darker brown. Postocellary ridges meeting in the median line 

 in an angle of about 120° with no conspicuous median promi- 

 nence. Occipital edge nearly straight, very slightly concave, a 

 scarcely discernible median concavity ; occipital hairs short. 



Prothorax brown, the anterior lobe lighter and the posterior 

 lobe darker, the inflated areas of the median lobe greenish 

 yellow. Thorax rich dark brown marked with greenish yel- 

 low (see fig. 3), the brown on the metepimeron lighter than 

 on the mesepisternum. Beneath and coxae greenish yellow, the 

 latter shaded and marked with light brown. 



Abdomen brown, marked greenish yellow; i brown, pale 

 below; 2 with a narrow median longitudinal stripe the length 

 of the segment and the sides broadly pale; 3 and 4 with the 

 merest trace of the same dorsal line, not discernible throughout 

 the length of the segment on 4; 3-6 each with a large dorsal 

 basal spot on either side of the median line, the two on each 

 segment narrowly separated, and with the inferior lateral mar- 

 gin pale ; 7 apparently pale basally to the transverse carina, and 

 with the sides below, posterior to the carina, largely pale brown 

 or yellowish ; 8 and 9 dark brown or black above, the sides ex- 

 tensively paler brown or yellowish, similar to 7 posterior to the 

 transverse carina ; to black ; appendages light brown or gray- 

 ish, darker at the extreme base.
