(584) 1 . Polydesma umbricola Boisduval 



Polydesma umbricola Boisduval, 1834, Faune Ent. Madagr., Lep., p. 108, PI. xiii, 

 fig. 5. Hampson, 189 i, Moths of India, II, p. 468. 



Three specimens, two taken at Medje in April 1910, one at Stanley- 

 ville, in the same month, 1915. A common insect in the tropics of the 

 Eastern Hemisphere. 



Rhynchodes^ Guenee

Plate XIII, Figure 10, 9 

 9 . Upper side of both wings moderately dark purpUsh brown; body on the 

 upper side concolorous; the body and wings on the lower side a shade lighter; the 

 fore wing is crossed by a fine dark median line, curving inwardly and running from 

 about two-thirds of the length of the costa from the base downwardly to the middle 

 of the inner margin, cutting diagonally across the end of the cell. Beyond this there 

 is a heavy black, or dark brown line, which runs perpendicularly from a point on the 

 costa a little before the apex to the inner margin, which it reaches about one milli- 

 meter beyond the inner angle of the wings. This band is accentuated both on the 

 inner and outer sides by a few faint reddish scales; the fringes at the apex and in the 

 excavated portion of the outer margin below the apex are dark brown. Expanse, 32 

 mm. 



The type was taken at Avakubi on August 30, 1913, and is in The 

 American Museum of Natural History. A paratype taken at Efulen, 

 Cameroon, by Dr. H. L. Weber, is in the Carnegie Mu.seum. 



Amphigonia Guenee 



(586) 1. Amphigonia complex (Holland) 

 Episparis complex Holland, 1894, Psyche, VII, p. 103, PI. iv, fig. 14. 



Two examples taken at Matadi, June 24, 1909, agree with the type. 



'There is another species of this genus known to the writer, which apparently has not been described 

 and which he takes the present opportunity to diagnose. 



Rhynchodes efulensis, new species 



c?, 9 . Resembling R. avakubi, but differing in having the ground-color on the upper side bright 

 eastaneous; in the males the median line in the three specimens before me is almost obsolete upon the 

 fore wings; in the two females representing the species it is visible, but very fine, and differs from the 

 median line in R. avakubi in not being curved inwardly, but running more nearly vertically from the 

 middle of the costa to the middle of the inner margin. The outer line crossing the wing in the males ig 

 heavier and darker than in R. avakubi; on the under side of the fore wings the costa is bright orange 

 with the cell at its end and the region immediately beyond the cell clouded with dark fuscous; the inner 

 margin of the fore wing on the lower side inclines to whitish. The lower side of the hind wing is orange- 

 red and there is a prominent black spot at the end of the cell of the hind wing on the lower side. Expanse, 

 25-30nim. Types in Carnegie Museum. Several paratypes. Habitat Cameroon. 



Closely related to avakubi, but easily distinguished by the brighter color and the orange costa of the 

 under side of the fore wing.
