Vertex and frons ochre brown, clypeus and occiput paler, more 

 yellowish. Lips yellow, a tendency toward orange in the free margin 

 of the labrum. Rear of the head and bases of the mandibles pale 

 greenish. 



Prothorax obscure yellowish, inclining toward ochre in the middle 

 lobe. Thorax brownish yellow, darker on the mesepisterna, which 

 in addition to the long hairs bear numerous closely-set brown spinules. 



Abdomen brownish yellow, perhaps even golden yellow in life, more 

 robust than in R. hollandi 2, the only species of this genus of which 

 a female is available for comparison, compressed and evidently partly 

 distorted. Vulvar lamina reaching to one-fifth the length of the lateral 

 margin of 9, flattened on to the sternum thereof 90 that it is impossible 

 to state its angle of projection, bilobed in its distal half by a semi- 

 circular emargination whose width is a little greater than its depth 

 and is subequal to one-fourth of the basal width of the whole lamina. 

 Appendages concolorous, longer than 10, a little shorter than 9, rather 

 stout, very acute at apex. 



Legs brownish yellow becoming darker distally on the tibiae and 

 tarsi, the third tarsal joint almost black; spines on the legs black. 



Wings hyaline, front wings very pale yellow at base, almost impos- 

 sible to say where this color ceases but hardly visible distad of the 

 level of the arculus ; hind wings a slightly deeper yellow at base, also 

 gradually fading out at the level of the triangle and at about two cells 

 posterior to the level of the hind end of the ash-colored membranule. 

 Stigma pale brownish yellow. Front wings with 19 antenodals, 13R, 

 14L postnodals, 2 rows of cells between Rs — Rspl a maximum of 3 

 rows in the anal field proximal to the triangle. Hind wings with 

 14R, 15L antenodals, 15 postnodals, i row (with i double cell) R, 2 

 rows L between Rs — Rspl, 4-3 rows between A3 and the hind mar- 

 gin at the level of the triangle. 



Abdomen 33, hind wing 43.5, costal edge of stigma of front wing 

 4.5 mm. 



I refer this individual to hinci because of its robust abdomen 

 and the presence, in three of the four wings, of two rows of 

 cells between the subnodal sector (Rs) and the supplementary 

 sector next below (Rspl). 



In this connection, I may remark that the size of the 

 pterostigma and very venational characters which Dr. Ris 

 has commented on in his descriptions of R. hollandi and R. 

 Moris (Cat. Coll. Zool. Selys, Libell. fasc. xiii, pp. 610-612, 

 191 1 ) lead me to think that it is his c hi oris which is the same 

 form as that which I described previously as hollandi, and that
