XXV. Descriptions of a new genus and two new species 

 of SpliingidjB, ^oitk general remarks on the 

 family. By Arthur G. Butler, F.L.S., 

 F.Z.S., &c. 



[Read 7th November, 1877.] 



Mr. Kirby having kindly placed in my hands for 

 description a beautiful new genus of the sub-family 

 Macro glossin(2, I take this opportunity of more fully 

 characterizing my genus Himantoides, and also of answer- 

 ' ing some of the remarks which Mr. Kirby has made 

 respecting my revision of the SphingidcB. 



Himantoides, Butler. (PI. IX. fig. 1.) 



Allied to Perigonia, but the wings much shorter and 

 broader, the secondaries more rounded, scarcely perceptibly 

 excavajted above the anal angle, not sinuated ; eyes less 

 prominent though quite as large ; antenna considerably 

 longer (so that if thrown back they would reach to the 

 middle of the abdomen), of the male thicker, of both sexes 

 with the terminal hook of nearly twice the length. Type, 

 Himantoides undata, Wlk. 



The example described by Walker consists of the head, 

 with one antenna, the thorax and the primaries of a female 

 example ; a second specimen (a male), was presented to 

 the collection towards the end of the year 1876 by 

 Mr. F. B. Sturridge ; it differs from the female in the 

 absence of all the blackish bands and lines, excepting one 

 which tapers from near the apex to the second median 

 branch, forming a partial boundary to the outer border ; 

 the secondaries are deep orange with a large triangular 

 interno-basal spot and a broad almost marginal band of 

 chocolate-brown ; the abdomen seems to have the general 

 coloration of the thorax, but the specimen is rubbed: 

 expanse, 1 inch 9 lines. 



Hah. — Jamaica. Type, B. M. 



Mr. Kirby quotes one or two instances in which I have 

 missed Boisduval's recent species. I am not surprised 

 because the book arrived in England after my paper was
