1899.] NATURAL SCIENCES OF PHILADELPHIA. 251 



I examined Rambur's type, now in the University Museum, 

 Oxford, England, September 3, 1896, and made some notes upon 

 its venation, some of which are incorporated in the above table, 

 while the others follow here: 



Front wings with 10 (right), 11 (left) antenodals, the last one 

 not continued to the median vein, 7 postnodals. Hind wings with 

 7 antenodals, 8 postnodals, inner (basal) side of the triangle a 

 little nearer than the arculus with which, if produced, it would form 

 a small angle; two or three posttriangular rows, rather irregular and 

 not symmetrically developed on right and left wings. Total length 

 of body 47 mm., abdomen 32, front wing 38, pterostigma 3.5. 



The data given for hova iji the table are based on the type male 

 and on a male from Nossi-Be, INIadagascar coast, given me by 

 Baron de Selys-Longchamps. 



Pseudomacromia speciosa (rj*) and pretiosa (Q). 



The data given for characters 3, 6-13, are drawn from Dr. 

 Karsch's and Mr. McLachlan's descriptions and figure {Ent. 

 Nach., xvii, pp. 73, 74, taf. ii, 1891, I'd, 1? ; Ent. Mo. Mag. 2, 

 ii, p. Ill, 1891, 2 d^, 19). For Nos. 1-3, 5 and 6 I am also 

 indebted to a letter from INIr. McLachlan, in which he expresses 

 his opinion, already quoted, that these two nominal species are 

 reaUy one. 



Variations of speciosa: 8. Of the three males known, one has 

 two submedian cross-veins in both hind wings (McLachlan, 

 /. c. ). 10. Dr. Karsch mentions that it is free on the left wing 

 of the male he examined. 



Variations of liretiosa : 6. Mr. McLachlan in his letter ivrites, 

 " one or two asymmetrical double cellules in the posterior wings." 

 8. Dr. Karsch mentions two on the left front wing of his type, 

 Mr. McLachlan three on the right hind wing of his specimen. 



The species of Pseudomacromia fall into two groups as regards 

 the tarsal nails; one (see the table, character No. 3) comprising 

 torrida and Donaldsoni, the other hova and speciosa (with pretiosa 

 as 9 ). Hova differs from speciosa in character No. 2, and perhaps 

 also in its' superior appendages, " munis en dessous et un peu 

 lateralement, ii I'endroit de leur epaisseur, d'une pointe trfes- 

 courte" (Rambur), a point easily seen in the male I possess. Ps. 

 Donaldsoni lacks this " point," and its presence is not mentioned
