One of the three males from Berbera has the triangle of the 

 hind wings crossed by one vein, and five rows of cells between the 

 principal and nodal sectors at the level of the inner end of the 

 pterostigma ; these are two of the characters given as distinguishing 

 C. divisa Baumann {Ent. Nach., xxiv, p. 342, 1898), a West 

 African species, from erythnea. On the other hand, the body is 

 no more slender and the amount of yellow coloring at the base of 

 the hind Avings no less than in the other two Berbera males, which 

 have the triangle of the hind wings free, and one of which has 

 five rows, the other four rows of cells between principal and nodal 

 sectors at the level of the inner end of the pterostigma. It seems 

 very doubtful, therefore, that divisa is a distinct species. 



It may here also be remarked that, on the page quoted from 

 Baumann' s paper, it is stated that " ferrugaria Ramb., Calv.," is 

 the female of erythnea. I pointed out the differences between the 

 two in Proc. U. S. Nat. Mt(s., xviii, p. 127, 1896, and subse- 

 quently showed /errH<7rtrta to be a synonym of xaitguinolenta Burm. 

 (Trans. Am. Ent. Soc, xxv, p. 9l"^ 1898). 



8. Pseudomacromia Donaldsoni u. sp. (P). X, fig. 5.) 



One male, Stony brook, August 17, 1894. 



(^. — Dull bluish black except in those parts noted below. Ver- 

 tex and most of the frons metallic violet, the lateral and inferior 

 margins of the latter pale brown. Nasus blackish brown, darker 

 in the middle. Rhinarium pale olive. Labrum shining black. 

 Labium yellow, median lobe and inner halves of the lateral lobes 

 black. Occiput black above, orange edged with black behind. 

 Rear of the eyes black and yellow. Mesepisternum and meta- 

 pleuron with some very indistinct, yellowish spots and stripes. 

 Posterior half of metasternum black with a pair of bright yellow 

 spots close to the median line. Coxse and trochanters obscure 

 brownish. Sides of first three abdominal segments pale broAvn, 

 evidently much faded. It seems quite likely that in life there was 

 a longiludinal yellow or brown streak on each side of the dorsum 

 of 3-7, uow^ almost completely faded. 



Eyes meeting for a distance a little less than the antero -posterior 

 middorsal dimension of the occiput. Tip of the vertex barely 

 concave in outline when viewed from in front. Face clothed with 

 black hairs, most numerous on frons and vertex. Frons without
