side just anterior to the median carina, and a subapical transverse batid 

 on either side (the above description of i and 2 appHes equally well to the 

 j)reserved specimen; 2 beneath, anterior to the lateral carina and the 

 auricles largely green, auricles beneath largely black with a broad bar of 

 blue, a dark spot on the margin of the genital fossa opposite and adjacent to 

 the spine of the anterior lamina, margin of the genital fossa, anterior to the 

 point of covergence. very narrowly l)rown and armed with a single row 

 of seven to nine low scale-like teeth ; auricles with eight denticles, the 

 anterior ones very small, increasing in size posteriorly) ; 3-10 above very 

 dark brown to black ; 3 has AL blue, large and shading out above, and MD, 

 PD, ML, and PL green and small; 4 and 5 have AL reduced and 

 the four green spots reduced ; 6-8 have AL greatly reduced to a narrow 

 transverse basal line and PL wanting; PD is almost gone on 6 and does 

 not appear on 7 and 8, and on these two segments MD and ML are greatly 

 reduced; on the posterior segments spots MD, PD, and PL are green or 

 bluish green but ML is duller being greenish or bluish yellow; 8-10 and 

 appendages black (all the above markings are more or less discernible in 

 the preserved specimen; beneath the abdomen is brown or yellowish brown). 



(Wings hyaline, costa dark, stigma reddish brown, venation black or 

 nearly so; anal loop short and rounded, separated from the anal triangle 

 by two cells; one row of cells throughout between Mo and Rs in all 

 the wings.) 



(Legs entirely black except as follows: first femora broadly green or 

 blue behind for the entire length, and the merest streak of yellow above 

 at the base of the middle tibiae.) 



Material examined : a single male, the type, taken near Puerto Berrio, 

 Dept. Antioquia, Colombia, January 31, 191 7, by Jesse H. Williamson, for 

 whom this beautiful species is named ; specimen in coll. E. B. W. In the 

 account of our collecting trip to Colombia (Univ. of Mich., Mus. of Zool., 

 Misc. Publ. No. 3) on the bottom of page 13 and top of page 14, I have 

 described the forest where this specimen was taken. J. H. W. found it 

 hanging on a vine in the shade in this deep forest. Jessci is a close but 

 very distinct relative of tibiata. Whether it will be found to have the 

 wide distribution of the latter species remains to be seen. Tibiata has 

 not been taken in Colombia but it has been taken in Venezuela in the 

 nearby Catatumbo River basin and there is no reason why these two hand- 

 some species may not at some future date be found in the same forest.
