« I A KK — TWENTY-FIVE NEW SPHINGIDAE [ Vol. Vllf ' 



Neogene corumbensis sp. nov. 



Al. ant. long., ef j M mm.; 9, 25 mm. Al. ant. lat., cf, 9 mm.; 



9, 9.. r > mm. Marg. est., d", 12 mm.; 9, 12.5 mm. 



Habitat. — Corumba, Matto Groaso, western Brazil. Two males and 

 two femalM in OolL B. Preston Clark, received from Dr. 0. Staudinger 

 and A. Hang-Haas. 



This form has the while occipital band of A T . dynaeus, but 

 it is cream-colored, not brilliant white. The ground tone of 

 both wings, above and beneath, is brown, where N. dynaeus is 

 gray. The abdomen also is brown, where N. dynaeus is black. 

 The hind wing of the male is not white, as in N. dynaeus, but 

 is uniform brown above and beneath. The white markings of 

 the fore wing above, so distinct in N. dynaeus, are in this form 

 almost entirely lacking. It is a singularly unicolorous insect 

 throughout. 



Coenotes maximus sp. nov. 



Al. ant. long., 9, 38 mm. Al. ant. lat., 9, 17 mm. Marg. ext.. 9 

 21 mm. 



Habitat. — Ceram. One female in coll. B. Preston Clark, received from 

 Dr. O. Staudinger and A. Bang-Haas. 



The entire insect is unicolorous and uniformly gray above and beneath 

 except as follows. The abdomen above has a heavy black median line, and 

 heavy black roughly triangular side patches on each segment, the points 

 downward. On the fore wing above is an irregular apical line, 11 mm. in 

 length, angled between SC4 and SC5, and between SC5 and Rl. A broad 

 gray pogtmedian band, darker in color than the general tone of the wing, 

 extends acroee the wing, roughly parallel to the distal margin, and turns 

 Bfl it approaches the costal margin. A second similar band runs par- 

 allel to the lir>t about midway between it and the distal margin. Cilia are 

 dark at the veins on both wings above. There are no markings whatever 

 on the under side of cither wing, except an apical line 3 mm. in length and 

 the darkened cilia at the veins. A very quiet-looking insect.
